Since its opening, the company has installed over 25,000 solar systems on homes, businesses, and schools, totaling more than 260 MW. RGS currently operates in 10 states: California, Colorado, Connecticut, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, Vermont, and Hawaii (under the name Sunetric).

Top Ranked Companies


The Good

  • Quick Installations
  • Variety of Payment Options
  • Online Monitoring
  • Customer Service

Quick Installations

RGS Energy does a good job of pushing the installation process along. After the initial consultation, RGS Energy works with its inspectors and installation team to get the system design and permitting taken care of. After the permits are squared away (which requires legal authorization in order to proceed), RGS gets the installation done quickly.

Variety of Payment Options

RGS Energy offers several payment options, including outright purchase, loan, lease, and PPA. With so many ways to pay for a system, customers have the ability to find an option that works well for them and their individual needs. RGS provides in-house financing for customers interested in getting a loan.

Online Monitoring

RGS Energy offers online monitoring to help its customers stay up-to-date with their solar system and its performance.

Customer Service

Customer service is a priority for RGS Energy. Many RGS customers have said that they felt the company listened to their concerns and made an honest effort to address and improve them. 


The Bad

  • Outsourced Installations
  • Limited Warranty

Outsourced Installations

RGS Energy subcontracts most of its installations. This can be problematic because it might result in miscommunication, inconsistent service, or lower quality work. Additionally, it's unclear which company you should contact-RGS or the installation crew-in the event of an issue with the system.

Limited Warranty

Although RGS Energy's systems comes with a 25-year warranty, it is a limited warranty that only covers the production of the panels. If there is an accident or something goes wrong with the equipment, it won't be covered under the warranty.


The Bottom Line

RGS Energy is an established solar company with nearly 40 years of experience. The company is available in 10 states and offers a variety of payment options, online monitoring, and quality customer service. However, RGS outsources most of its installations and has a limited warranty.

Rgl Fresno, CA

RGS was referred to us by a friend as a top co, only they left the state and are now in Colorado. Our solar system does not work and they came out, for $350., and said there are issues with the panels as well as with the installation. They said that they would not repair them until we first paid the $350. Service charge. They said they would then repair them and referred us to their customer service. Their customer service ? has not responded to repeated texts and messages left on the phone number they asked us to call. We are extremely disappointed in their product and lack of supposed customer service. We are elderly people on a fixed income, we feel betrayed and disappointed in what we thought was a “good” company.

RGS energy is the worst company my wife and I have ever worked with...PERIOD! The sales pitch is strong and convincing, over promising. Once you sign all the problems begin. They out source all the work to shady independent contractors. When signing up, they told us we would not need to do anything with our existing electrical panel. Wrong! LADWP made us upgrade and move the entire unit at a cost of $6000. The contract stated they to bury the electrical conduit. I got home from work and they had bolted it to my cinderblock wall. Further, they damaged newly done landscaping and sprinkler lines, killing many plants. Early this year during the heavy rain in Los Angeles, we noticed leaks and damage to our ceilings. Our roof is only 4 years old. Contacted our original roofer and he completed and extensive report with all the poor workmanship RGS performed. RGS improperly installed the panels with no rain protection on the bolting to save money. I have spent $15,000 to have their work redone. Filed a formal complaint with the CA State Contractors Board, filed a claim on their bond, and have arbitration next month. Avoid this company, they outsource to companies that bid the cheapest and the end product is a disaster. Further, our electric bill does not show the decrease we were promised in the written contract. ***Update March 2018*** So we won the $15,000 max settlement after spending more time and money in CA arbitration after a long fight. The CA department of consumer affairs and the arbitrator found in our favor. Although getting back the money is one thing, the costs far exceeded $15K due to RGS out sourcing ALL of their work to independent contractors. We will be pursuing complaints against the install and roofing companies. RGS energy would not settle with us, driving this to arbitration despite our hired expert. Avoid this company at all costs. Your house may be damaged and depending on what state you live in there may be a cap on the money you can get back after a year of battle!

If zero stars was an option I would give them zero stars.They came to my home and evaluated my roof for solar panels. They let me know that my roof had at least another 10 to 20 years left and proceeded to install solar panels. When the rains came three months later and the roof started leaking the first thing my contractor noticed was that many of the solar panel attachment points were not in studs/stringers but in fact there were screw holes right through the roof/ceiling. In addition, many parts of the roof had bad or spongie decking. None of this happened in three months. My belief is that they wanted to put up a $35,000 system and didn’t care to let me know that I need a new roof first because they thought that that might be where I put my first $35,000. I did end up having to remove the solar panels $5000, replace decking and put on a new roof.$20,000. I do not recommend our RGS. When I contacted them three months after installation to let them know our findings they ignored me.

Robert C Franks Fresno, CA

We live in Fresno, California's Central Valley that has experienced a 6-year drought. In September 2013, RGS installed a 20-panel solar system. In February, 2017, after our first significant rain in those 6 years, we discovered a roof leak and subsequent ceiling water damage caused by cracked caulking around a roof jack located approximately 6" from the RGS solar panel system. We know this to be true as it was reported by a 3rd party inspector hired by RGS. The inspector resealed the area around the leak and we have had no further leaks. We sought repair of our ceiling from RGS in February. RGS denied our request for ceiling repairs taking until June 2017 to make that decision. RGS offers only a 1-year warrantee that is responsible for installation damage within 24 inches of their panels. Bottom line: no rain, no warrantee.

RGS Energy bought the company that did solar installation for our complex. In October 2015 they acknowledged that they owe us warranty service for defective inverters. On February 4 of last year, we got this in e-mail from them: "Just so you are aware RGS has declined to perform any service in the complex over there so you are going to need to find a local installer to come and do the swap for you. " Yes. "Declined." They understand that they owe us warranty service. They just aren't going to provide it. It's been 16 months since then, and while after untold yelling and screaming a few homes were fixed, they stopped doing that work about a year ago before most were done. (I, personally, was lucky.) Most still have not been fixed. Most installations are generating no power, some going back to 2014. tl;dr: Just because RGS understands that they owe you warranty service doesn't mean they'll actually furnish it. This is not a company to work with.

RGS was a valuable resource during installation period (unfortunately the person who was the sale contact has subsequently left the company). He was able to answer questions regarding time of use billings, system sizes, roof placement, etc. that others could not. After 3 years need warranty work on 1 panel - and am currently patiently waiting and reminding RGS that it is under warranty. Spent 2 weeks leaving voice mail messages with no call back. Finally placed service request on their website (it appears that is the only way to contact customer service). RGS has acknowledged there is a problem that needs to be addressed, but they have not been able to schedule a repair. Currently on week 7 of waiting (I contact the customer service dept every 2 weeks - to not appear too pushy). I don't understand why they cannot schedule a service appt. for 1 individual panel. I would strongly suggest looking elsewhere for installation - as their warranty service is horrible. It didn't take 7 weeks to purchase and install the system - but it takes longer than that to get warranty service (and I'm still waiting).

In Oct. 2015, RGS installed three solar panels on my roof. The project was supposed to include registering them so that I'd receive SREC payments. On Dec. 16, RGS learned that it would have to install a meter to register the panels and billed me an additional $487.50. Rather than accepting responsibility for its failure to include the necessary meter in its work order, RGS attempted to raise the cost of the project ex post facto from $3,930,30 to $4,417.80. It's this kind of practice that recently caused the Better Business Bureau to revoke its accreditation of RGS. Unless you enjoy being treated the way I have described, I suggest you steer clear of this company.

Two years after installation my roof was damaged by 2 inch hail. I have trying to get RGS to remove system so that a new roof can be installed. I am getting nowhere talking to RGS. Straight out---I have been lied to! they tell me a permit is going to be applied for with local building inspector on a specified date, and a week later no permit application. I leave phone messages looking for reply as to what is happening. I get no return call.

RGS was great when we purchased our system but our system is been down now for months and we have made about 10 calls to try and obtain service and nobody has returned our phone calls. Meanwhile our soda solar panels which we paid $30,000 for are not reporting the energy that they are generating. I do not recommend this company!

We had 24 panels installed 6 years ago. Since then we have had 11 inverters replaced and now have 5 more needing replacement. We have been waiting 2 ½ months to receive the replacement inverters. As of yet we have been giving only excuses for the delay. We are loosing confidence with RGS.
