  • I have told all my friends and neighbors about the benefits of our solar installation!
    Dear Mr. Castillo and Mr. Sandoval, This note is just to inform you that the solar production at my residence for year two has exceeded the contracted amount. I am quite pleased, and the system has been performing well. According to the TIGO measurements, in the period 9/1/17 to 8/31/18 my system produced 6820.34 kwH versus the agreed contract amount of 6419 kwH. I hope my system continues to perform as well for the next 23+ years. I have told all my friends and neighbors about the benefits of our solar installation, but so far no one else to my knowledge has yet made the commitment. Perhaps next year.

  • Operational in 5 weeks!!!
    Unbelievable. Went from site inspection to system being fully operational in 5 weeks.
  • They were very quick to follow through!
    I have been very happy with the service the folks at SolarUnion! They were very quick to follow thru at every step, and extremely responsive to every question.
  • They encouraged me to go out and keep comparing
    The energy auditor gave me a bid and actually encouraged me to go out and keep comparing. He told me to compare value, quality and performance guarantees then come back to them. I have to acknowledge I had never been invited by a salesperson to stop the conversation right there, go out and compare.
  • Solar system is delivering incredible power!
    The optimized solar system is delivering incredible power and more than enough to zero out the electric bill and sell some to the grid.
  • Comfort and Specialized
    SolarUnion was large enough to give me the level of comfort I needed that they would stand behind their 25-year output warranty as they advertised, yet still small/boutique enough to take a job that was too complicated for anyone else.
  • 25-year Performance Guarantee
    They offered me a 25-year Performance Guarantee, which just blew me away. That operation/servicing agreement alone has huge value. Yet, they offered the entire solution to me plus the performance guarantee at a cost below that of standard solar installers that did not offer a performance guarantee at all.
  • They did not walk away
    My roof is a challenging one and many solar companies simply walked away - Solar Union did not.
  • Going the Extra Mile
    SolarUnion has earned my business not by slick sales talks but by going the extra mile.
  • Personalized service from the start
    Personalized service from the start, reasonable cost, excellent design and a solid installation - I highly recommend Solar Union as your next solar installation company.
  • SolarUnion was onsite starting on the installation within a week
    Within a week or so of accepting their bid for the project, SolarUnion was onsite starting on the installation. The project manager was polite, clean and very communicative throughout the process which took 2 days to finish.
  • They were prompt with their install, and everything was done in a top-notch manner. I love my solar system and would call them in a heartbeat to do more work for me.

  • The customer service was excellent, and they went above and beyond my expectations. They are heads and tails above all of the other installers I interviewed.

  • They were straight shooters, and they weren't like other companies, who tried to sell me something I didn't need.

  • I was impressed by the SolarUnion team. I found them to be honest and they did an excellent job of educating me more about solar.
    During the summer months I use my AC every day. I did plenty of research to see if getting solar would help lower my PG&E bills. I noticed that the larger companies were the most expensive. I was disturbed by the fact that most of them aimed at tier-shaving or partial offset only to remove the most expensive PG&E rates. Then a relative recommended that I contact SolarUnion, a company solely focused on full offset. SolarUnion worked with me to offer me the most attractive financing option with $0 down at a monthly payment that was below my average monthly payments to PG&E. The monthly payment was all inclusive and covered for system maintenance and installation and performance guarantees. Sweet! I was impressed by the SolarUnion team. I found them to be honest and they did an excellent job of educating me more about solar. It was not a hard sale. As a matter of fact, my assigned energy auditor encouraged me to compare and asked me to call him back once I was absolutely convinced that SolarUnion was given me the best value and quality mix. I called him back within a week and signed up. The first time I paid for my solar system was when I saw results. I have effectively locked my electric rate with SolarUnion. Yes...the great part is that they are able to fight even the lowest tiers/rates from PG&E. I now pay PG&E only for interconnection fees. $0 for electric consumption. When I started the process I knew that a solar system on my roof was a long-term commitment. I have complete confidence that the SolarUnion team will be with me for the long-run. Regarding post sale service and operations: a couple of months ago they visited me to clean (power wash) my panels as soon as they noticed that my system's performance had a little hiccup...some dust collecting on one of the panels. SolarUnion's operations team was proactive. I did not even know the system was underperforming. They took the initiative. I am confident it is going to be a smooth ride with these guys.

  • I was referred to SolarUnion and they offered me the most attractive option with $0 down at a price that was competitive, including system maintenance and installation & performance guarantees.
    Mi casa tenía gastos altos de electricidad, con incrementos cada año. Era la dura realidad. Sabía que con un sistema solar ahorraría. Eso estaba clarísimo. Mi duda era con quién cerraría mi contrato y quién merecía mi confianza. Comparé varias opciones en el área de la bahía y me di cuenta de que las empresas grandes eran las más costosas y lanzaban mucha publicidad. Un poco sospechoso. Me refirieron a SolarUnion que me ofreció la opción más atractiva con $0 de entrada y a un precio que era el más competitivo, mantenimiento de sistema incluido y garantías de instalación y performance. Me impresionó gratamente la transparencia y honestidad del equipo de SolarUnion. Me guiaron a través de todo el proceso y me ofrecieron diferentes maneras de financiar el sistema solar. La primera vez que pague por mi sistema solar fue cuando vi resultados. Como debe ser. Ya varios miembros de mi familia han adoptado solar con SolarUnion. Continuamos contentos y ahorrando. ¡Gracias, SolarUnion! (English Translation) My house had high electricity costs, with increases each year. That was the harsh reality. I knew that a solar system would save money. That was clear. My question was who would close my contract and who deserved my trust. I compared several options in the Bay Area and I noticed that large companies were more expensive and throwing a lot of publicity. A little suspicious. I was referred to SolarUnion and they offered me the most attractive option with $0 down at a price that was competitive, including system maintenance and installation & performance guarantees. I was pleasantly impressed by the openness and honesty of the SolarUnion team. They guided me through the whole process and offered me different ways to finance the solar PV system. The first time I paid for my solar system was when I saw results. As it should be. Since then several members of my family have adopted solar with SolarUnion. We continue to be happy and saving each month. Thank you, SolarUnion!

  • I paid no money down and am saving instantly off my electricity bills. I now enjoy the benefits of a high-quality solar system. To make things even better, thanks to the solar addition my property has definitely experienced an increase in resale value.
    I am not an emotional buyer. So many questions went unanswered in my search for solar! Until I found SolarUnion. They answered all my questions and made the process easy for me. We sized the system to my needs. At my household, we also preferred a system that was not visible from the street. The SolarUnion team accommodated our request and designed the system so the solar panels would be placed out of eyesight. I also appreciated that I had the option to either purchase or lease the system, with or without financing. The SolarUnion team's dedication to customer service kept me well informed throughout the entire process and advised me to go for the zero money down option. Yes! I paid no money down and am saving instantly off my electricity bills. I now enjoy the benefits of a high-quality solar system (SolarUnion only installs Tier 1 components) on my hard-earned real estate investment. To make things even better, thanks to the solar addition my property has definitely experienced an increase in resale value. With SolarUnion, I have so much more than a solar electricity provider – I have a reliable long-term partner.

  • I have been 100% happy with the way it’s worked out…and a few of my friends in Lincoln have also used SolarUnion and have been very happy as well.
    Basically I started my solar inquiry in 2012 and found so much deception and marketing crap with many companies (not all, but many). Being a financial planner and very analytical (I also have a law degree which helps me see through the B.S.) I needed to see the numbers and so I set out to do a detailed comparison of all the options commercially available. I asked all for a 5.06kw system quote to keep things equal…and you really don’t want to lease solar unless you have no equity or ability to pay for or finance an system. After considering most of the major players (see spreadsheet) I was pretty set on going with [other company] when an older gentleman knocked my door and offered a free solar consultation. I accepted as I hadn’t heard of the company SolarUnion, and set a meeting with a sales representative. It was a great experience as I could tell the salesperson knew his stuff and was not pushy or manipulative in any way. Then I saw the numbers! Note that if you buy a bigger system (like a 6‐7kWp) then your savings actually increases. My Lenar house is about 3,000 sq ft and we went with a 6kWp system…so far it’s replacing all our usage (we were shooting for 95% to stay in tier 1 PGE rates). We signed up and SolarUnion was in contact with me through the whole process. They were GREAT to work with and handled the permits and every aspect of installation and interconnection with PGE. I spent a lot of time researching panels and inverters and considered installing myself. Solar Union also offers ongoing maintenance and they installed optimizer so I can see my power generation online each day. They warrantee the system for 25 years. I have been 100% happy with the way it’s worked out…and a few of my friends in Lincoln have also used SolarUnion and have been very happy as well.
