Solar Installation Group - Solar Installation Near Me - Oakdale, California

Our experience with SIG has been unacceptable. After installation and payment, SIG solar became largely unreachable. We have made multiple phone calls over the years needing assistance with system issues and were constantly told someone would call us back. Those calls rarely happened, to the point that my husband drove 40 miles to their office just to speak to someone in person - with no resolution. Because SIG solar failed to provide support, WE had to contact the inverter manufacturer, twice in the past few years to get the system functioning, something the installer should have handled. When we just recently realized that we needed our roof replaced, SIG solar charged us $8000.00 to remove and reinstall the panels. We had to pay it because we did not want to do anything to jeopardize our warranty, effectively forcing us into this expense. This company appears focused on sales, not long-term service. For a major investment like solar, this level of non-responsiveness and lack of accountability is unacceptable. Experiences like this are why homeowners rely on consumer protection and contractor oversight agencies. read more

We recently had a problem with our solar panels and system being down. So we are here, way out in Copperopolis, worried about paying a high PG&E bill while my super expensive solar panels sit not working, on my roof. We find out that the company that installed our system had gone out of business. But the first place we called we got lucky!!We talked with Christy at Solar Installation Group, SIG, and she arranged for a technician to come and check out our system . So, super friendly and knowledgeable, Brian came out .He replaced the faulty inverter and had our system up and running in no time. So now we feel very confident about using the Solar Installation Group for any of our future solar needs!!! They really turned what could have been a big headache into a super non stressful event, thanks SIG !! read more

Choosing sunrun is a huge mistake! The salespeople are good at saying all the things to get you signed up. Then they disappear, never return any calls, and everytime you do talk to someone they promise to fix the problems then ghost you again. They hooked up the solar all wrong, almost caused a fire, and we were left with a $12,000 true up with PGE! It's been over a year and a half, and I still can't get in touch with anyone to fix it. I highly recommend avoiding sunrun like the plague! Horrible customer service, unresponsive with any issues, all around a horrible experience that is costing us thousands of dollars! read more

I've contacted Sig Solar dozens of times over the past year to get a constantly failing Generac inverter fixed. They came out to take a look at it in MAY 2025, and it's now the end of October. I should not have to constantly call them to get my $100,000 solar install working. This is not a one time issue. The last time I had a problem, they played this same game, and it took over a year to get it fixed. This is costing me thousands of dollars in lost energy costs. My last yearly energy bill was $5000 and that is WITH a 16KW solar system. What's the point of hiring SIG Solar if their systems fail for a large amount of the time they're available? read more

I've been hemming and having over solar for a while and since the tax rebates are now going away after 2025, I decided now was the time. My sales rep, Damian Fernandez made me feel like a friend and didn't use any high pressure tactics to get me to commit. He came up with a system to put me at net zero with PG&E and presented it to me and my wife. After answering all of our questions and seeing the future savings over continuing to pay the for profit utility provider PG&E, we've made the choice to go solar. I'm very happy with the process so far and will update when the project is complete and we are switched over. I definitely recommend Damian to assist you in your solar needs! Leo Ayala is great too (assisted Damian at the house visit). read more

I highly recommend SIG solar, contact Daniel Martinez (209-702-9708) or Gina Gallegos (209-552-1218). They spent the afternoon measuring and looking at everything, giving us great options. We ended up with 15 panels and a Franklin battery (btw there are great reasons for Franklin VS Tesla battery); we have plenty of solar during the day and battery runs us through the night or as a back up. If you give them a call you will be very pleased. read more

What an amazing experience I had with SIG Solar from beginning to end. Having been highly recommended by a friend, I decided to try out SIG. It was Deanna Greener's visit and extensive explanation of the system's benefits from start to finish that convinced us to go solar. Throughout the installation process, she kept in constant contact with me and was always available to answer any questions I had. Thank you for the professional work of the installation team. I appreciate the respect, care, and cleanliness they demonstrated. If you are considering switching to solar, I would highly recommend using SIG Solor group. read more

Sig solar group installed a $115000. Solar System on my property about a year ago right? The main panel is falling off the Pole. I called them to repair it, and they want to charge me $750. They used poor workmanship when they installed it. read more

My sales person and the entire installation team from SIG Solar have been nothing but amazing, absolutely professional and going above and beyond even when they didn't have to. I would highly recommend them for all your solar needs. Feel free to hit me and and I can get you in contact with them for a free estimate. The tax credit is at 30% as of right now! No better time than the present to go Solar. read more

Josh Clark and the team at SIG Solar were excellent to work with. Josh was always proactive, patient with my questions, flexible and friendly. He designed and managed the perfect system for us, with honest pricing and was constantly following up to make sure the project was going as planned. The panels they purchase are high quality, easy on the eyes, and come with a great warranty. The install team were quick and friendly and I'm very happy to have been referred to SIG. read more

sig solar installed our system 2 years ago. The first year my true up charges were 1025$ second year 925$ why? Because on initial visit they underestimated how many panels we need to accommodate our usage even after reviewing our pge bills for 1 year. We have a pool and spa I believe it is their job to predict this. Guess what the response is? Well you'll have to buy more panels sorry. Well im sorry too, sorry I used them. Be very careful with these people. read more

I cannot help but wonder how much SIG pays for these reviews. Unfortunately, I had a similar experience to many others. We received great service up front, good on the installation, etc. However, when an inverter went bad, less than two years after installation, they caught it 5 months later. They at least came out and fixed it, but we went through the best energy-producing months (April - October) at 50% inverter capacity. The net result is several thousand dollars extra at true-up this year. When they sold and installed our system, they said monitoring was part of the package, but the person I spoke with today said customers need to monitor and call if they notice anything wrong. The person I spoke with also said they cannot monitor the system without SolarEdge working. However, SIG called me in October and said one of our inverters was not working, so they obviously could still see there was problem. Why did they wait 5-6 months to do something? This was a large install on a farmhouse (over $80k), and they can't even monitor the system. They were quick to point out that Solar Edge is responsible for monitoring, but we have to upgrade our connectivity to 5G...for more money in order for monitoring to continue working. We own three other homes for which we are considering solar. As much as I would love to support local businesses, I can't do this again with SIG. Their poor support and customer service will cost me over $5k in True-Up this year. There is zero chance I ever use or recommend SIG again. Sadly, because of this experience with SIG, I am leery of trusting any locally-owned solar group for the other homes. Fortunately SolarEdge support was helpful and told me I can buy wireless plug-ins or the 5G cards to get back on-line. Unfortunately, I have to call our solar installer to request the parts and install. At this point I am wondering if I could just pay a monthly fee to another Solar company to take over maintenance and monitoring. The thought of giving SIG any more money is sickening. read more

Starting in 2020, I began researching the addition of a roof-top solar system for my home in California, and I evaluated many solar installation companies. Based on the quality and efficiency of what SIG offered, plus the stellar reputation of the Solar Installation Group (SIG), it was a simple choice to go with SIG. My local sales person Jennifer, was very knowledgeable, completely honest and patient with my decision process. I am completely satisfied with the quality of the components and the installation work done by SIG's employees. I can absolutely recommend SIG to anyone looking for a quality solar system without reservation. They are the good guys, and a local hometown company. read more

We've had our solar now for 6 months and couldn't be happier. We had so many companies tell us our home wouldn't work for solar. But SIG took the time to come out and work creatively on a solution. We are now saving money every month, and feeling good about doing our part to reduce energy consumption. Thank you to Deanna and the whole SIG team. They are so courteous and responsive! We highly recommend them! read more

Th quality of work is outstanding. Every promise of their contract has been abided by. No false hope. And we have saved a ton of money.

*****UPDATE 6/2/23****** Within a couple of hours of posting this review, my rep Damien Fernandez reached out to me and was willing to do all he could to make things right. He called the office and they sent me a copy of my solar agreement details right away. Also, on 5/31, a SIG solar tech came out to my home to install the last breaker that was needed to get my system started and up and running. I appreciate the efforts that were made to solve our issues. I do wish it wouldn't have taken this review to get a copy of my solar agreement but we can't change the past. Due to the remedy in the issues I had, I'll be upgrading my rating from a 3 to a 4 star. ---------------------------------------------------------------------------------------------------ORIGINAL REVIEW: 5/24/23 My rep was Damien Fernandez. He was very informative and genuine upon our initial interactions at the almond blossom festival where we stopped at his booth. However, we have some issues that weren't resolved and it's disappointing considering we spent so much money on this system. We never received some sort of receipt for the project. When I requested this from Damien, he asked for clarification and I told him I wanted to know what I was paying $73,000 for. A simple receipt that would say something along the lines of (panels $50k, labor $20k, permits and other misc costs $3k). So he told me that they don't provide that because "no company provides info to customers regarding how much they're paying for the materials from the manufacturer and how much their mark up costs is and how much the customer ends up paying for it". That wasn't what I was asking for, and of course not something I'd expect any company to provide. I just want to know what I'm paying for. That was back in February and here we are 3 months later. I got the run around of "the office will get back to you", which they didn't. Today is 5/24/23, our system was installed on 5/3/23 and we're still missing a breaker (should be installed next week) and the 'Emphase' app to monitor the usage/output isn't working. Overall, the initial consult was great, the installation/installers were extremely professional, it's just the follow through that has left a sour taste behind. If you're wondering how they have so many reviews, it's because they have their reps compete with each other on who can get the most reviews. So they haggle the customers over and over til they get your review. I purposely avoided reviewing because I didn't want to leave any negativity, but I was contacted about 4 times to leave a review, so here it is. read more

SIG Solar provided me an excellent install experience. They asked me about a few details regarding the house and then they started right away. We thought that we would be without power all day but it really was off just 4 hours. They were finished and gone before I got home. Throughout the process my salesmen Damien was extremely helpful and provided me updates from beginning to end. I will be referring any friends and family to SIG Solar! read more

SIG SOLAR ROCKS! We purchased our home solar from SIG and had an incredible experience. Beginning with a discussion of the solar panels and micro-inverters that would be used to maximize our return on investment, Jason reassured us that our system would drastically decrease our electric costs and might even eliminate them altogether. We loved his straight-forward approach and appreciated the time he took to answer all of our questions. Then Jared came out to map the design of our solar system so that it would not impede the look of our home from the street. This made us really happy as he was able to maximize solar production without causing an eye-sore for the neighborhood. Upon installation, Paul made sure that the SIG crew did a nice and neat job and kept pipe-runs and boxes discreet from visibility. First-class all the way! Throughout the intake process, the office staff and installation crew were first class and made the transition to solar an absolute breeze. SIG was upfront and honest in their pricing and delivery of a quality product. Over the past 6 months, we have saved thousands of dollars! Thank you to Jason, Jared, Paul and the SIG Crew! GREAT WORK! read more

Have to add another 5-star rating to SIG (Solar Installation Group)! From my initial meeting regarding solar to the installation, SIG was courteous, informative and responsive to my questions. The attractive solar panels are nice and tight to the roof and I can't wait to minimize my "wonderful" PG&E costs. I did go with additional panels to prevent the potential "True up" end of year bill from PG&E...all with no out of pocket costs. SIG took care of permits, arranged financing and provided excellent referrals for the roof install (True Roof) and tree trimming (Sindelar Tree Service). Highly recommend! read more

So was referred to this company by a close friend. Since first contact they have been nothing short of amazing. Great communication, excellent service and all my questions have been answered. System and main panel replacement were completed today without a hitch. Have referred two(2) friends to them and both have signed on. Family owned and run with excellent service. In the ever competitive solar industry they stand alone. Rylan Kerr was my sales rep and was on-site for the install day to confirm all was completed above expectations. Give them a call ask for Ryan to give them a chance to compete. You will not be sorry. Dale Souza read more

Highly recommend using SIG as your solar company. Josh Clark was awesome to work with and he explained everything in a way we could understand. He was super friendly and knowledgeable. He even used spread sheets, which I loved, to show our potential savings and gave us options so we could choose the right plan for our specific family needs. The install team was very clean, professional, and FAST! We could not believe how quickly the process went. They even did all the paperwork and made all the phone calls to get approval from our HOA. We are very happy with this investment! We have been telling everyone who will listen, GO SOLAR! read more

Rylan and Sig Solar were the best ! Rylan was so helpful with all of our questions and concerns. He was so kind and professional! The installation process was completed without any issues or complications. We are beyond happy with choosing Sig Solar and are so very thankful for all Rylan has done for us! We will highly recommend Sig Solar to everyone! read more

This company is very unprofessional! We started the process in May 2022 with Josh as our rep. He promised and swore that he would be with us through this. And then we didn't hear anything from him our the company until August 2022 when we contacted them about delays. Ashley & Rachel let us slip through the cracks. Then only got on the ball when I started making calls every day. This was a horrible experience and feel that others should know about the way SIG handles business. read more

10 STARS** If you're thinking about getting Solar, we recommend SIG Solar. Our Representative Damian Fernandez sat down with us and explained in detail all the benefits and services they had to offer. From day one, it was a wonderful experience. The Crew of gentlemen that installed were fast, efficient and knowledgeable. The job was done in one day and PG&E inspection completed the next day. Damian went the extra mile and gave good feedback with all our questions. Excellent communication each step of the way and beyond. I highly recommend you request Damian Fernandez as your SIG sales representative. read more

The team is professional, polite and the installation process was extremely quick. This was the second system I have had them install on my property. I didn't realize I was going to be getting an electric vehicle in the future or that California's desire to eliminate propane as a possibility. Sense I had already done business with them the decision was a no brainer, especially after obtaining multiple quotes. read more

We purchased 56 panels for our farmhouse which should take care of everything on our property as well as future usage like adding a shop, swimming pool, hot tub etc but my PG&E bill is still $250 to $300 a month on top of $460 solar bill. Maybe we're using too many space heaters. I get that, but when I called to ask about it, no one called back.I came to the conclusion (by myself since no one called back) that I may need a battery back up. I called 4 times and still no response. When I finally got a hold of someone, they said that they don't sell battery backup for my system! I spent a lot of money on our solar. Their customer service is not what I expected. They don't call back which is unfortunate. Only reason why I was insistent on getting a quote from them is because they know exactly what I have. Installation people were great but post sale is pretty horrible. read more

SIG installed my solar as a subcontractor back in 2019. In hindsight, that was a mistake. The general contractor added needless cost. Next time I'll hire SIG directly. Anyway, SIG did a great job then. Ashley and Hasten in particular were particularly nice during my most recent experience described below. A few months ago the inverter died. (It took me a few weeks to notice.) The general contractor ghosted me, so I eventually called SIG directly. Their entire staff was very nice. They installed a new inverter today for a very reasonable price. (The old inverter is under warranty, but not labor.) Thank you SIG! The process took a while, but you can't expect a contractor to put big projects on hold to take care of unprofitable warranty work. That's particularly true in my case since, technically speaking, I was not their customer in 2019. The fact that they were willing to fit me in at all is very much appreciated. read more

Hey Solar Installation Group/ SIG, thanks. Solar installation on a very vertical roof on a home built into the side of a mountain with a roof not perfectly aligned for catching the sun. But bam! Attractive installation is already producing, even during cloudy, rainy days, more energy that we use from power grid. This is saving us hundreds every month. Great team to work with, friendly, professional, efficient. No out of pocket. Financing simple. Even helped secure a great affordable tree crew to trim for sunlight enhancements and included this in overall package. We worked with Matt Sexton officing out of Jamestown/Sonora focused on the needs of Tuolomne County, but SIG goes everywhere in the region. read more

I am updating my review from one star to three stars. Because they finally came out to help me with my expensive system I called five times asking for help. But when I gave them a bad one star review they came right away. I wish I didn't have to wait so long and miss the hottest days of summer but the technician was great and very friendly read more

I purchased a home with a solar system that had been installed by SIG. End of December they contacted me regarding a possible inverter failure and sent someone out...tech said he just needed to reboot the system and all was good. 9 months later my true up bill is $1400 and I learn that the inverter has been out since mid December. SIG knew it was broken, lied to me about it, and now won't return my phone calls. read more

Rylan was, and continues to be, great through the whole process. He is very knowledgeable in every aspect and had an answer for the million questions I asked. I am not one to make a quick decision and he showed nothing but patience and understanding. He went above and beyond without hesitation. Their team did a great job with doing a super clean install. They were quick, efficient, friendly and professional. I would 100% recommend SIG to anyone looking to get solar. I went from a guy who doubted solar was the right move to a guy that now checks how much energy the solar panels are generating at least once a day. read more

Phenomenal team and staff. Great to work with this team. I highly recommend to anybody looking for solar services.

This company put Solar on my 89 year old father's home in Sonora in September of 2019 on a old roof that was 29 years old and at the end of its life for $30,000.00 Now my father has passed and to sell the home we have to put on a new on his home and Jason Kerr told my husband $2k to remove and reinstall and now they want $7k to do that job. Buyers Beware - they take advantage of the older community and should have advised my 89 year old father who had Kidney Failure and Parkinson's to get a new roof before installing the panels. Not an honest company in my opinion. read more

After shopping around at different solar companies, I finally found SIG Solar and I couldn't be happier. Deanna met with me at my property the first day I called, with a plan and system specifically for my house, which was amazing. She was patient with me as I navigated the purchase, even when I waited three months to install. The customer service was on point and not overbearing. I especially like the quality of work and the family feeling you get working with them. Overall, Deanna and her team deserve more than five stars. I would definitely recommend SIG to anyone who needs solar. read more

This was one of the worst experiences I have had with a company that tells you that they will help anyway they can. My wife and I have had to do all their work for them from getting ahold of PG&E and HOA. It was a big let down the be told in May this would be done in August but here we are in September now being told it will have to be done 4-6 months from now. read more

We just had additional solar panels installed through SIG, and had the best experience. The owner came out and was on top of the house working out the plans. The Installers and Electricians were knowledgeable, polite, and very respectful. I believe we received the best value and service possible. Plus our Sales Representative, Gina Gallegos was able to answer all our questions and walked us through the complete process! Thank you very much!! read more

Great solar company ! Rylan Kerr sent over a quote within a few minutes after I requested for one. He kept me updated with the whole process and was great to deal with. Jared did an excellent job on making sure the solar was positioned to maximize efficiency and had awesome customer service . Ashton, Andy and Greg did a really great job on the install. I would recommend to anyone interested in solar to contact Rylan Kerr to get started. read more
