Excellent Service Very knowledgeable Very Professional He was very courteous and very helpful in answering all questions read more

my only regret I have is I should have done it much much earlier I had so many questions from all the information on the internet. Vincent made it easy for me to understand and he was able to answer all my questions. It took a little longer but I would rather it be done right than sloppy. I recommend calling Vincent in case anyone is wondering if solar is worth it or not for them. read more

SolarVast installed SunPower X-22 solar panels on my house back in 2018. I have referred many friends and family members to Ken Lau of SolarVast for their solar installation. SolarVast's installation was quick and they handled all the permits and paperwork with the City. I have not had any problems with the installation or the solar panels. I highly recommend SolarVast and SunPower's solar panels if you are in the Southern California region. read more

I picked Solar Vast because they offered Sun Power panels gave me the best deal for Maxeon panels with the option to redo my roof. Sun Power is of the highest quality solar panel companies with excellent warranties. Solar Vast is considered one of their "master" dealers. Ken Lau was my sales rep and he was initially responsive and informative about the process. It took 4-5 months from signing the contact to redo my roof and set up the solar panels. There were some hiccups along the way, but Cindy helped us sort out the issues. My solar system was turned on due to delays from SCE which lasted another 6-8 months. But I finally got my solar system set up last October (1 year after signing the contract) and it has been working well for us so far. read more

I compared a few solar vendors and Solar Vast presented me the best option, they are very responsive and has scheduled the installation and inspection in a very effective manner, not to mention their support after the project completed is still excellent. read more

Willie and his team were great with communication and installation of my Sunpower solar panels in October 2023. I met Willie through a referral at the height of the NEM 2.0 applications. Solar Vast was swamped with orders and delivered the solar panels within the 6 month promise date. The permits and city approval went of smoothly. Now, 7 months after, I have not had any issues. By the way, Sunpower customer service was helpful when my phone app was not working. I thought the solar panels were not generating energy. It turned out that I needed to delete and reinstall my app. No information was lost. read more

I referred this company to my client and they were very satisfied with their solar panels. I would definitely refer this company to my future clients looking for solar panels. - Maple (Feng) read more

Very smooth process from beginning to end. I highly recommend Solar Vast! They're very professional and I'm extremely happy with my Solar. read more

We were shopping around for solar given the rising cost of the electric bill. We were introduced to the Sales Representative named King Lau. He was professional, detail-oriented, and patient with us throughout the entire process. He clearly explained to us the steps, the finance part, and broke down the costs and terms to the level that we could understand. We had 15 panels installed. The company is great. The panels are high quality and have been saving us a lot of money, especially during the hot summers when we have to turn up the high ac. So far, everything has been beyond our expectation. We high recommend this company and our Sale Representative. read more

It can be overwhelming to know which solar company to go with with so many options out there. Willie from SunPower assisted us 2 years ago with our solar purchase. He was helpful from the beginning and has continued to follow up each year for a system report to make sure our panels are running smoothly. With 2 EV's, our electricity bill is either net zero or we have gotten a small credit on our bill. We plan on using Willie again to help us with our next solar install in our new home. Go with Sunpower, you won't regret it! read more

Did not propose accurately, and replacement service was three times greater than new installation

Overall communication about each step of the installation process could be better. Because I had friends who went through the process I knew what to expect and asked the appropriate questions. Someone new would definitely be lost. read more

Great company, Ken Lau has been great help throughout our process I Recommend 100% we Are very satisfied with our panels, so far this has been a great investment. read more

We have had a very positive experience with Sun Power and our representative has g9ne about and beyond for us. We have recommended th8s company to our family and friends. read more

Solar Vast was a great company to work with. Willie was very patient with our questions and he proved to be a subject matter expert. Each step of the process took time, but he let us know approximate time frames and kept us in the loop. He was always accessible by phone or text and responded promptly. The installation went well and the technical team was great. Highly recommend this company for your solar needs. read more

solarvast has been really helpful and has helped my parents with setting up their system which is working great!

I cannot recommend Solar Vast highly enough. They were in all respects completely courteous and professional, and they installed a state-of-the-art system which I am very happy with. They communicated everything in advance, so I knew what to expect. The sales person I worked with was Vincent. He was at all times knowledgeable, courteous, and helpful. He answered all of my many questions. I honestly don't have even a single complaint about anything related to my solar installation. The first company we contacted was through a national discount shopping warehouse. That company produced a good offer, but we decided to shop around. I wanted Sun Power solar panels, if possible, because I believed they would probably last longer and be less likely to fail than panels by their competitors. I found Solar Vast, because they were listed as a Master Dealer on Sun Power's website. They had a lot of positive reviews online, and after dealing with them I can understand why that is! Between the two vendors we were looking at, Solar Vast provided us with more information while we were making our decision. Their solution was technically superior to the other option, because it included micro-inverters on each solar panel vs. a single inverter. The price was comparable, but the competing vendor proposed to install solar panels by a different company (not Sun Power). All things being equal, I'd rather have Sun Power panels. So, we decided to go with Solar Vast. They pretty much handled everything in regard to getting permission from the power company to install the system and turn it on. It did take some time for those approvals, but I think that's to be expected. The installers were professional and courteous. Again, everything was communicated to me, so I knew what to expect. At the end, I received a packet with pictures of the installation and spec sheets of the various components. I couldn't be happier with the experience and the final installation. read more

The whole process was easy and fast for us. We got a proposed plan from them based on the our electricity usage and sun coverage of our house. Once it's signed, they requested the permit for us, and came over for installation. We had grounding issue which they also helped us to fix it. Then scheduled a inspector to check while they waited more than half day for the person to show up just to make sure everything is good. They took care pretty much everything for us. Pretty good experience, would recommend. read more

Great services! Joanna was our sales representative, she was responsible and helpful, she always responded quickly. We are glad to choose SunPower team to work on our solar panels. read more

Solar Vast was great! Good customer service. Ken was professional and helpful. Good value and quality.

I had a great experience with SunPower, especially with my rep Leon Yeh. He was professional and thorough and explained all the details carefully to us. We got the solar panels installed smoothly with no hassle and now we save a lot of money to charge our Tesla. Highly recommend! P.S. if you want to reach Leon, his # is 626-616-3356. read more

When it comes with sales, they are good, they will come to your house and call you everyday. When you need customer service, good luck on that. They have all kinds of excuses. Be careful read more

I recently had solar panels installed at my house & had a great experience with sunpower by solar vest. The process was clearly explained to me & I was guided through all steps of financing & installation. In addition, the app they use allows you to view how your solar panels are producing & what your use/gains are. Overall a very easy process, with personnel readily available if any questions arose. Highly recommend them to anyone contemplating going solar! read more

The whole process was great! Ken our sales rep couldn't have been nicer and was always an email away with an answer. They brought the panels one day and the next day they were installed. Sunpower and Solarvast is a good marriage. So what are you waiting for?? Save the planet!!! read more

Really glad that I went with Solar Vast. I got quotes from different companies and Vincent was honest, thorough with his explanation and provided me with the best price. From start to finish, he was consistent with checking up on me to make sure I knew what was going on. My SCE bill was around $250 average, even higher during the summer months because of the unbearable SoCal heat. Now, I'm only paying about $120 total! I didn't realize Edison had extra fees on my electric bill, such as the "Public Purpose Programs." I don't know how the solar system works but I'm glad I don't have to worry about it since it is all monitored, insured, and maintained by SunPower. Overall, I highly recommend going solar because the amount that I'm saving is enough to cover my other housing utilities and it's environmental friendly. Double plus!! P.S. Don't forget to ask Vincent about the referral bonuses! read more

To whom it may concern: Im writing to express my frustrations with sunpower. We have been having problems with the solar and till now no one has reached to us. Its been over 2 months and nothing is happening. The problem has not been fixed despite me following up several times as if Im not busy and just sitting at home. I called today again for like the 6th or 7th time and finally someone was able to give me the number to make an appointment. Everytime I called I was instructed that they have sent the request and just wait for the call from technician. After over 2 mos of waiting and being charged by edison for 2 months bill I finally get the phone number to call for appointment. It seems that there is a communication lapse because the number I called to make appointment never received any request from customer hotline that I need service. And after calling to make the appointment the earliest time they can come is Dec. 22. So after waiting for 2 months I have to wait anothe 1 1/2 month meaning I will be billed again by Edison. We average around 200$ a month so that means I have lost 400$ so far plus another 300 for 1 1/2 month. Plus the 86$ a month sunpower has been charging each month for services that was not actually rendered. I AM VERY UPSET FOR THE POOR CUSTOMER SERVICE. VERY INEFFICIENT SYSTEM. read more

I'm so glad I went with solar Vast! Everyone was super professional and I would definitely recommend to anyone who wants to go solar.

I have SunPower solar panels, I bought them from Solar Vast. I already wrote a great review because Solar Vast was perfect during the selling and installation period. Another company was recently polishing my concrete floor and when they attached their machines to my electrical panel (they had to open it and remove the front cover) the power went off and solar panels were also disconnected. That concrete polishing company messed up something in my electrical panel so I could not connect again the solar panels. I had to call Solar Vast, and in few minutes a technician was there and fixed everything. He also checked my panels because it seemed to me like one panel was not parallel and well aligned with the others. But instead everything was good. I did not have to pay anything, Solar Vast was very responsive and effective, and fixed everything very quickly. I am very happy with them, I would have not trusted another electrician (the concrete polishing company had also an electrician), because solar panels are important and delicate, I don't want to mess up things in the electrical panel. It was - clearly - during the covid-19 period and the Solar Vast technician was very careful in wearing masks, gloves, keeping distance etc. Thank you Solar Vast! (I don't remember the name of the technician unfortunately). read more
