Allterra installed our solar panels years ago and just recently had to remove and reinstall them for a house remodel. We have dealt with many different contractors and vendors over the past year and encountered many stressful and frustrating situations. We were honestly expecting something to go wrong in the reinstallation process, but Allterra's team was organized, set clear expectations and communicated promptly and respectfully. What a breath of fresh air! We now know an excellent company is not easy to come by and greatly appreciate their work. Highly recommend without reservations! read more

Shout out to Tamara Kleinman in Sales! I called Allterra based on their awesome Yelp review. I needed advice on how to approach adding to my existing solar system. She called back promptly, was a great listener, and came across as friendly and helpful. She really represented the company well. I look forward to working with them on things in the future. read more

We were able to sneak in to NEM-2 and needed to delay installation until after the rainy season and a new roof. We were pleasantly surprised that Allterra was both patient with our nearly-a-year delay as well as extremely responsive when we were ready to move forward. The installation went exactly according to plan without any additional costs or surprises. We love the dashboard and seeing how our energy bill has dropped significantly. We had received less expensive quotes but Allterra's reputation amongst our friends and Aptos neighbors made the difference for us. Michael worked with us initially to answer all our contract questions, and Saki's team led a professional and timely installation. Thank you so much, we are thrilled! read more

I was very impressed with the quality of their work. The install process was very smooth. Each person that came out explained what they were going to complete that day snd then let me know when they finished. They explained in great detail how the system works and walked me through setting up the apps for the panels and the battery. A job well done, I couldn't recommend anybody more than Allterra Solar. read more

They designed and installed a residential solar project for us, and it works even better than we had hoped. The equipment they installed is of top-notch quality, the quote was competitive, their staff was knowledgeable and professional, and their work was clean. We highly recommend them. read more

We had Allterra install our solar last year and couldn't be happier! We were impressed with the customer service and quality of the product then and we continue to be impressed with Allterra's continued care now. The consultation call with Jet was great; he took the time to thoroughly explain everything from the recommendations for number of panels to the quality and warranty of the panels themselves as well as what Allterra would be doing in the process. We appreciated that it was low pressure; he simply gave the information, answered all of our questions, and then left it up to us. The installation was also easy (and that was even with us requiring scaffolding for our high/steep roof) and painless. Saki, Nick, Miguel, and Fidel were our install team and they were great. They explained every step along the way and took the time to answer any questions we had. They were also just a lot of fun to be around:) You can tell they really love what they do and that says a lot about a company. The entire process of dealing with PG&E, permits, inspections, etc. was completely and competently handled by Allterra. We were really happy with the work that was done as well as the production of our panels and then Allterra really went a step above and beyond. Tamara emailed about 6 months after the installation with a ton of useful information on maintenance and upkeep as well as documentation and info on the PG&E/3CE billing process. I have had to call her a few times to clarify questions and she is always happy to help. It's amazing to have a company that cares about their customers after the work is done; we feel truly valued. When shopping for solar options, you can probably find some with cheaper quotes than Allterra but you'll get what you pay for. I did a lot of research and between customer care and the quality of the product, you can't beat Allterra. I have friends who went with other options and their stories are complete nightmares of poor quality panels and zero customer service. We can't recommend Allterra highly enough. read more

These folks deserve 6 stars, honestly. Getting our roof ready for the install was a slow, painful process... that's totally on us and unfortunately what Allterra had to work around. We're part of a small HOA/condo association that had a much older roof which took *forever* to get handled. Despite my constant delays and "dunno when that's going to happen" all the folks at Allterra Solar were saintlike in their patience. They were able to sneak us into NEM-2 before that closed down, exactly as promised. When we did get scheduled, the install was so quick! Just as advertised too; they said about two days and it was actually just under. They fully explained how it would go/went, what to expect and any other questions I could come up with. I experienced nothing but quick, patient handling my excessive regular questions and concerns. Jet, Jeremiah, Eric, Ashley, Rebecca, Adam... all the heights of professionalism. I really can't say enough good things about them. When (if?) I want to add batteries to my setup I can't see why I wouldn't go with Allterra. read more

Once again, Allterra rates as the absolute best Solar Company! A special shout out to Tamara, who did so much to help me organize and decipher my PGE bills. A huge thank you to Perry. Perry is exceptional at communicating, both via email and on our online chat. Perry provided information specific to our solar and energy needs. His honesty and expertise are much appreciated. Thank you again to Allterra Solar! read more

I should have written this review a while ago for extreme satisfaction on my initial consultation, to the communication throughout the entire process to get me on NEM2, to the installation and followups.. but it was my interaction with Allterra that prompted me to not wait any longer. I think ALL the things I mentioned regarding how happy I was / am with Allterras solar install are important, but what were really doing with such a significant investment is putting trust in a company in hopes that they will also be there on the other side of the install; that they will stand by their work. Well, im here to tell you that Allterra's customer service is everything I hoped it to be. I recently had a leak in my living room and i immediately notified both Dadarrio (who did some amazing roof work for me prior to the solar installation) and Allterra. There was no question in my mind that I felt the leak was being caused by the installation of panels directly above the living room where the leak appeared. Jeremiah was extremely responsive and scheduled 2 techs to come out to investigate the leak. Eric J. and Brian G. came out, and immediately started looking for the source of the leak. I often need to ask people to take off their shoes on the carpet but there was no need here. They both took their time to thoroughly investigate the source and it was determined it was no fault of Allterra's installation. They showed me pictures of some areas from the install and how it related to where the leak was happening and it was clear to me Allterra was in the clear. If everything stopped there I would have been plenty satisfied with their response however, Eric and Brian went on to locate the source of the leak and determined it could have been in 2 separate areas where roof nails were corroded on the outside immediately where the leak happened. They continued to inspect the area and went as far as to seal these areas for me. I think that's pretty awesome. I consider myself lucky to have landed with Allterra, but i think Allterra should feel just as lucky to have Eric and Brian representing them. Top to bottom Allterra ROCKS!!! Thank you so much!! read more

I've got nothing but great things to say about this company. Everyone here, and a big shout out to Eric and Jet, for making sure everything went according to plan. I had a few companies come out and give me estimates for our house. Alterra was by far the best panels and pricing. Do yourself a favor, and become educated about solar when your looking into it. All panels are not made the same, with the same amount of guaranteed degradation. There were a lot of companies, who will remain nameless but they aren't small, who wanted to install less efficient panels for a lot more. Don't let some of these companies tell you that you need a re-roof, when more often that not, you don't. Alterra did nothing of the sort and provided the most efficient, top of the line panels possible, for a very reasonable price relative to the competition. I can't speak for some of the other reviews on here, but given how I was treated, I would recommend Alterra to anyone who asks. I always received a response back in a timely manner, they were never to busy to answer any of my questions, and they even made a trip to get a few extra tiles (expedited) because rain was coming and they didn't want anything to happen if it did. If that isn't over the top customer service, I don't know what is. They didn't HAVE to do that, but they did because that's doing the right thing. Lastly, You can tell a lot about a company by the small details. All of the metal piping was custom bent, and matches the recesses on the house. Just the amount of time they spent on that alone shows me they care about how they do things. I've seen other solar installs and nothing was as clean as how they did the install. All the wires are clearly labeled, the correct length, and routed properly. read more

We just got 14 panels (EVPV410H PV) installed by Allterra. The overall experience was positive. To start the office staff was able to get the paperwork submitted to PGE well in advance of the deadline for NEM2. The install crew led by Saki and Jeremiah arrived as scheduled, took the time to explain what they would be doing over two-days, answered all questions, and completed the work on time. The panels immediately started to generate power. Allterra was able to get the final inspection by the county a day later and now we're just waiting on PGE to initiate NEM2. There was only one issue that they addressed immediately. read more

The Alterra crew of Saki, Nick, Michael and Julian arrived at our home ready to work. They completed their tasks in a very professional manner cleaned up their material and explained our new solar system in detail. Eric also from Alterra met with our City inspector to receive our approval, he also walked us through the system and answered our questions in detail. If you are considering Solar go "local" with Alterra Solar. read more

I had my solar+storage system (Enphase), and EV charger installed by Allterra Solar. They did it faster, better, and with better support than other companies I had gotten quotes from (and even started working with). I don't think I've ever been so happy about any service I've had before. Every single Allterra Solar employee I interacted with went above and beyond--including accommodating OCD-level requests about positioning of conduits or centering of the panel array. Everything went as smoothly as it could have. Even after the system was installed, running, and completely paid for, Allterra Solar continued offering great service and secured a rebate for my storage system. This review is a bit overdue as I have had the system for over a year now, and I've been VERY happy with it so far. If you're looking to get a solar system you should definitely reach out to them. read more

I had a great experience with Byers from Allterra Solar. I was worried that my problems would have required a truck roll and hours of labor but we were able to resolve the problem remotely over the course of a few days. Byers went above and beyond the call of duty for me. She definitely deserves a raise! read more

Like others here, I started as an enthusiastic supporter of Allterra and sent many to them (sorry to you all). Just over a year in, the system suddenly dropped (and stayed) to less than 50% output, I've been hit with a large trueup and Allterra won't resolve, instead pointing to the manufacturer (SunPower). I'm stuck with half the system I bought, and no recourse. Caution! read more

Allterra Solar - Just over a year in, Allterra's system dropped to less than half output. - Solar Installation Near Me - Santa Cruz, California

'Poster child for customer service' We installed solar approx. 10yrs ago and recently had our inverter go 'off line' with a voltage fault. We rang two solar companies locally as the installers we used went bye-bye. The 1st ones we got hold of told us 'we don't help anyone with solar unless they are one of our installations'.. Allterra were much more helpful and Casey McDonald was on-sight within 24hrs. He was super efficient, extremely knowledgable, fixed the problem quickly and documented everything we needed to know for future reference. So a couple of conclusions ; 1. AllTerra will be our goto solar company 2. AllTerra you are very lucky to have Casey Thank you sincerely ! read more

Hi, I want to give a round of applause for Derek! Prompt, professional, polite, courteous, hard worker, and incredibly knowledgeable of the system inside and out. He saved me a lot of work updating and adjusting the system so we did not have to move any Comcast Internet lines. He was very careful getting on the roof walking on my new roof and was very sensitive not to damage the other panels on the roof while he changed out an inverter. He is a great associate for Allterra Solar and represents the company well. In business, you're known by the company, you keep, my grandmother used to say in Spanish "tell me who you hang with and I'll tell you what you are". I think about that whenever I meet Service representatives from various companies. This is a solid organization with good people. I highly recommend them Because they have great associates working for the company which means the ownership cares about their people. I have recommended this company to numerous families over the years. One of the best things about Allterra Solar is you can get right to the owners of the company if you need to unlike these huge corporations that send you overseas whenever you call their customer service number. Thank you Derek for doing a great job. You represent the company well. Ron. read more

Allterra installed a 22-panel system on my house in Fall of 2019. The entire process went without a hitch from sales through installation. Allterra worked with me upfront to answer my many questions and they worked with me during installation to do their best to minimize the many aesthetic issues that almost prevented me from adding solar to my house. So far the system is performing exactly as promised. Only downside is that they are on the expensive side. Their bid came in about 10% more than another bid I received for the exact same system. (This competing bid came in late - after I had already signed up with Allterra. I stuck with Allterra because of my excellent customer experience. I was worried that the other guy's customer service would be lacking as evidenced by the extremely tardy bid.) read more

I chose Allterra for my solar installation​ after speaking with some of the larger companies (SunRun and Solar City). Allterra was the only company who could do what I wanted them to do, and who could answer all my questions. And believe me, I had about a million questions. I worked with Paul Brown, who was very patient with the sales process, even though it took a long time. The installers were great and fast, and so was the process of getting the HERO loan (which you should get if you're considering solar if it's still available). I have not had any issues with the panels and it's been about a year now. The PG&E bill has been very low. read more

They are quicker in responding. I will recommend them to all my friends. This is my second time requested to checked what was leaking. They are professional and Lee he has this calm voice. Abel and the other guy who works there are very helpful. I will recommend them again read more

We began to consider putting solar electric panels on our roof in February 2021, and had serious conversations with four companies. The first week in March we signed with Alterra. The reasons we chose Alterra are 1) At every turn they were quick to respond to our concerns. 2) Michael Taylor, our Project manager, never pushed us to make a decision, and gave us ample time to consider the decision to move ahead. 3) They never made claims on performance of our system. but did convince us that their experience and commitment to customer satisfaction drives their business. 4) I think the Enphase system that they recommended is the best on the market for residential applications. 5) I have a tech background, and know enough about how Solar works to be annoying, but Mike never got annoyed and resolved all concerns I had. The process for permits, site survey, inspections and final design took about 3 weeks, all done by Allterra, all much quicker than promised. We only had be available for inspections. PG&E began crediting us for our access power production 30 April 2021 - 5 weeks from signing the contract, and again, much quicker than promised. The system is producing exactly as expected. Allterra Solar was wonderful !!! Communication was flawless, they accommodated our preferences for installation detail, the crew was friendly, efficient and respectful of our property, there were no surprises or unexpected costs. We heartily recommend this company. read more

My Electrician recommended Allterra Solar for my client in Felton. Mike at Allterra met with my clients walked them thru the process, the best location for the panels, and the expected return on investment. My client was Thrilled with the service and end results. I highly recommend them for your project. Sincerely, Eric Lamascus www.DiscoverElite.com read more

Our solar system installed by Allterra has been up and running for a year now and we just received our first annual "True-Up" statement from PG&E. We are extremely happy with the system and Allterra. Prior to having the solar system we were paying PG&E between $300 and $325 per month (over $3,600 per year!). During the first full year, we paid PG&E a grand total of $113, saving us over $3,500! We could not be more pleased with the outstanding and professional service we received from Allterra during the installation and the results after one full year of service. I highly recommend Allterra to anyone considering a solar system for their home or business. Jim Carroll read more

Allterra installed our system 5 years ago. They were easy and honest to work with, and they made the process easy. I was surprised by how little money it cost us to go solar. This year a home project required us to take a few panels down, and put them back up in a new location. Allterra impressed again. They made it easy to schedule the work, and the installation crew went above and beyond to satisfy. Ask for Byers and Saki by name! Thank you! read more

We chose Alterra for our solar instalation after checking out all the biggies (Solar City, etc.) and several of the local companies. Alterra has been wonderful! They answered our (many, many) questions, helped us figure out our particular needs, gave us lots of info. about solar in general and their panels in particular, worked closely with our roofer (we had the roof replaced at the same time) and...they did NOT hound us to death with a hard sell like Solar City did. We've had our panels for almost a year now. When I have had questions I have called and always gotten immediate replies. This winter has been cold and wet and dark - lots of lights on and use of the small electric heaters and our PG & E bill is low low low. Solar is the way to go...and Alterra is the company to do the work. read more

Allterra was employed to install my 2nd solar system in the sleepy beach community of La Selva Beach, CA - being part of an HOA, my unit was the first such system in the entire complex. Allterra met all HOA requirements and was patient while the HOA board reviewed our proposal and eventually approved installation. When the date for the actual install came the work was done well, efficiently and with great care. Follow up visits to fix minor issues were completely quickly and with an excellent attitude. A friend of mine was also getting solar in the same time frame and he got bids from multiple solar vendors, and eventually picked a non-Alterra vendor. He was not happy and the install did not go as planned, Alterra was picked to "fix" the install and go forward with the project - he now regrets not picking Alterra when he had the chance, and if a do over was possible Alterra would now be his first choice. Having the chance to compare two vendors has lead my friend to conclude Alterra is the clear choice! Allterra's vast solar install experience, friendly staff, efficient communication and excellent attitude make them a top choice for your solar install needs! I highly recommend them. read more

I have had my system for 1.5 years now. I was thrilled at first and was recommending Allterra to everyone I know. Now I have rescinded those recommendations, because their ongoing support is non-existent. They have not responded to any of my inquires over the last year, which included how we could add to my existing system, how to determine why 2 panels underproduce significantly relative to the rest, and other questions about the new Enphase products. I was very happy with the installation, and the team who worked on ours was great (though they did not secure themselves at all while on my roof, and frankly it made me nervous because I have a 60 foot drop from the roof to the ground where the system resides). And I am still happy with the system overall. But now I am stuck with a system where 10% of the panels seem to not be working, and I am getting no support at all from Allterra. I am all about going local, but I am more about getting treated fairly. To top this off, I had a system installed on a rental property I own (I was very enthusiastic about Allterra back then) and that has been a complete disaster. The inspection never passed and they ignored repeated requests to get everything finished, until the permit expired and then they tried to stick me with blame. I cannot recommend this company, sadly. read more

I just want to give a shout out to Mike at Allterra Solar, who's integrity and honesty just saved us from a potentially financially fatal decision. Because of him, we're going to be able to afford several projects to improve our property (including having solar power), instead of just one or two. They're saving us money providing a top product and in the end we'll actually come out ahead because of some incentives they were able to point us to. Mike looked at the plans another company had given us for our project, and was able to point out the flaws and where the company had flat out lied to us about their system's output ability and installation possibilities. They can essentially do the same work, but make it look better and it'll cost us almost $15k LESS... and they were able to point us in the direction of good 3rd party advice about our financing options that would save us literally tens of thousands of dollars over the life of the loan we're applying for. The other company lied to us and told us several things we wanted to hear, but in the end we would have been very sorry when we learned that it was all lies just to get our business. A quick cross check told us that Allterra was acting in our best interest as a future customer, and it was a no brainer. We're going with them. Thanks, Allterra, and Mike! read more

I was referred to Allterra Solar by a good friend that I work with. I have an existing two inverter installation with three strings of panels which have not been working correctly for at least a year. One of the strings was bad so i disconnected it until it could be fixed. Anyway I called Allterra. They sent one of their best techs, Casey, out to debug my setup. In the end he not only found the root cause and fixed it, he also checked the rest of the installation painstakingly to make sure the problem didn't occur elsewhere. Demonstrating his great knowledge base, he also swapped strings to opposite inverters because that could potentially yield more energy(long story). In the end, I consider this service that absolute best I could have hoped for and I'm actually kind of giddy that my system may be producing more power than it ever has. 5 stars for Allterra Solar and its people!! I highly recommend them for any solar project you have. I plan to use them again. read more

Allterra did a nice job from consultation through install and continuing until permitting was approved and the system connected to the electrical grid. I had to nudge them once for an install date, but that was the only hiccup. They were patient with me on my final payment as I was waiting for a home equity line to fund. Based upon my experience I have no reservations recommending them to other. read more

Allterra Solar just installed a system expansion to the beautiful system they installed back in 2015. Another stunning project! Great communication, knowledge and installation. Each person is a pleasure to work with. Nothing has changed - they are simply the best Solar Company out there. If you want a stressless experience and a perfectly installed and working system, do not look any further than Allterra Solar. read more

I contracted with Alterra for a solar system for our house. As an architect, aside from design, I'm very familiar with permit processing, contracting, trades in general and recognizing a job well done when I see one. Alterra scored top on all. From Jet and James, to Jeremiah and installers Ed and Chris, you can expect great service. Casey, Charles and Eric great sparkys. And from the office, Alyssa kept us informed of every step. I really appreciated the effective, prompt communication. Job well done! it's been a pleasure. Thank you, Miguel Podolsky read more

These guys did grey water systems in the past, in addition to solar. Even though they don't do them anymore, when they realized I was interested in one, they went above and beyond to help with any information they could! I learned a lot They even contacted me a week later to let me know about a grey water workshop to help me get started! Their customer service rocks, and the people that fill this local shop are awesome. When I'm ready for solar... They will be my first stop read more

You're in the best solar hands if your working with allterra on your solar project. Local customer service is invaluable these days. Everyone from the sales team to installation team to the commissioning team was a pleasure to deal with and their work ethics and efficiency was just awesome. Coming from a career in Power Generation at the Moss Landing Power Plant and understanding all the different systems and moving parts required to make electrons, I can't tell you how excited I get knowing that my solar system, with ZERO moving parts consistently provides all the necessary electrons I need on a daily basis! So friggin stoked on the Allterra Solar system! Make the call, ask for Perry and the rest will flow. read more

We had excellent customer service from start to finish with Allterra. Our system has been up and running for 4 months now and we've had no issues. We purchased an electric vehicle this summer, and so the sun now powers our car - pretty cool. When I first looked into solar companies earlier this year, I was very thorough. I started with local companies who were endorsed by neighbors on NextDoor and then interviewed and got bids from three. Allterra was the clear winner for us because of the combination of panels, warranty, happy customers (yep, I called multiple people- this is a big purchase!) and price. In addition, I learned along the way that Allterrra was the only company I interviewed that always had their facts right about PG&E and solar more broadly. I learned a ton from Jeff our sales contact (who was a customer himself before he became an employee). They were very thoughtful on the configuration so that we could get maximum energy production while still making it look 'balanced' on our roof. And they did an good job hiding the conduit for the wiring. Their price was not the cheapest but was close enough. They finished the job a few weeks ahead of schedule. They were also flexible to work around my work schedule for appointments- and thoughtful not to ring the doorbell when they arrived early for appointments, as I had mentioned I'd be on conference calls from home. Anyway, we couldn't have been happier with the people and the process. read more

Allterra did everything in their power to make it right after I posted the review. There was obviously nothing they could do about past service but they worked hard to make me a happy customer. This included a follow-up after installation to get education on how to track performance of the panels and how to access/use the information available from PG&E (available for everyone, not just me!). They also swapped out the generic charger I had purchased with a Tesla-specific model and did not charge for the swap out. And Paul sent their expert to do the swap on the charger so it went super smoothly. read more

This experience was so easy! We had spoken to multiple companies in regards to having solar panels put on our roof. We never felt confident and would walk away saying, someday - but then we met Perry from Allterra.... we had a conversation NOT a sales pitch. From the first talk to the finished product the communication was amazing. We never had to track anyone down to find out what was going on (which seems like what we have to do with any company these days). The install looks beautiful and they even went above and beyond to make the conduit blend in to my roof color. Eric at Allterra kept us in the loop in the final permit sign-off stage to make sure all went smooth. We are already seeing huge savings in the first 2 months. I know there are many solar companies out there and I am sure many of them do a great job, Allterra definitely did the job and more. Thank you to everyone that had a hand in our project - we are so happy! read more

Allterra Solar rocks! They were outstanding from day one. Their customer focus and attention to detail is a model by which all other service companies can learn from. I was hounded by "another" Solar company for quite some time. It seemed like all they were interested in was the sale and not what that would mean specifically for us. We were repeatedly bombarded with cold calls and emails for months about "when did we want to get started". Not so with Allterra. When Josh came out, he sat for a couple hours with us and explained everything we asked him about. He followed up once and then left the decision in our hands. No hard sell and no pressure. And the customer service did not end with Josh. Everyone at Allterra was excellent during the entire process. The engineer, installers, project manager, final inspection guys and even Alyssa in the office are all at the top of their game! Very easy to work with and quite knowledgeable. When I call Allterra, I feel like I'm talking to a family member. I have no regrets with my decision to go with Allterra, and don't hesitate at all to recommend them if you are considering going Solar. read more

This review is for Aaron Powers specifically. He is the most helpful, knowledgable, dependable and efficient person I think I've ever worked with in any field. His dedication to customer service and satisfaction definitely shows through in his work. It's clear he's very passionate about his job and loves what he does! I'd recommend Alterra in a heartbeat to anyone based on my experience there. read more
