Consistent Products and Warranties

Even though Complete Solar works with an extensive installer network, the company is able to provide homeowners with a consistent product lineup and system warranties.

Complete Solar systems also come with a 25-year equipment warranty (delivered by the manufacturer), which protects the system in the event any physical components are defective or otherwise underperforming. All systems also come with a 10-year workmanship warranty, which is considered average for the solar industry. The workmanship or labor warranty covers the work put into the system, along with necessary maintenance.

Solar Energy Storage Available

Complete Solar's Battery BackUP program allows solar customers to take full advantage of their solar panel system through solar energy storage upgrades. Solar batteries are quickly becoming the most sought-after addition to modern solar systems because they improve overall system efficiency. Homeowners can store surplus solar energy and use it for the following applications:

  • Emergency use during blackouts or utility grid outages
  • Nighttime use to reduce dependence on fossil fuels
  • Electric vehicle charging (home integration system required)
    and more

The Bad

  • No NABCEP Certification

No NABCEP Certification

We were unable to determine whether Complete Solar has itself received certified status from the North American Board of Certified Energy Practitioners (NABCEP), which is responsible for some of the most highly-regarded solar technician training programs in the solar industry. That is not to say that Complete Solar has not partnered with local installers that have the NABCEP stamp of approval; but once again, customers will need to inquire directly with the installing company for this information.


The Bottom Line

If you live in Complete Solar's broad service area, and are having trouble finding a qualified, local installer, Complete Solar may be the solution you're looking for. The company has partnered with dozens of solar installation companies across these states, and provides them with a technological advantage that streamlined the entire process — from securing an initial quote, to the actual installation, to interconnection and system monitoring.

As always, we encourage readers to investigate the latest Complete Solar reviews before making a final decision, and comparing available financing options and product offerings with other leading solar providers in their neighborhood.

Rachel Appleby Palmdale, CA

The time frame in which our panels were installed was super fast. We had good communication leading up to the installation and it only took two days to install. We had a slight issue in which we noticed after the fact that the installers had sealed some of our roof tiles, implying that they had cracked. When we addressed the issue, they said that the cracks were already there before the installation and that they were trying to help us out by sealing. We appreciated it but wished that had been communicated to us before they did it-- we were home at the time so it definitely could have been done! However, we have no complaints so far and the panels seem to be working well, 9 months in.

Darlynn has kept me up to date with the whole process, with phone calls and messages. If I had any questions and I called, she usually picked up the phone any answered my questions. The whole installation went smooth and installers were always willing to answer any of my questions and kept me up to date with installation. There were no problems with inspections and now we are energized

I had Complete Solar Solutions install my system four years ago. At the time, they were the only company I spoke to who were able to get me all of the rebates and credits without my filing for tax breaks. There was some broken roof tiles (typical for installations) and they paid my roofing company for the repair -- no questions asked. The installation crew was great. They went over and above what was required of them. There is a website where I can monitor operation of the system. Customer service has always been responsive.

Complete Solar customer rating even after the merger sits at 6.2. I qualify for Federal, State and Local programs and with California new bill Complete Solar was still charging me. The system didn't include a battery system and when I asked I was told it was very expensive and I didn't need it. I don't have a generator and would still be relieing on PGE. When my neighbors started sharing there experience with pushy sales people just stopping by and a uninvited manager showing up on there doorstep when they cancelled. After seeing the percentage of your bill payed out in commission it will make your stomach turn.

Initially I was rather frustrated with the way my contract with Sunrun had been handled. Judy was very prompt, patient and helpful in responding to my concerns and questions. Based on the input I received from and through her I was comfortable to proceed. I appreciated our working relationship.

Complete Solar has been out to our home on 3 occasions upgrading inverters and replacing a defective panel. In all cases, the company initiated the service and it was provided at no charge. They continue to monitor our system and provide performance reports monthly. The initial installation of our 25 panels in 2011 was prompt and without any problems. We purchased our system outright so have no information on financing or leasing. We are very satisfied with Complete Solar and will refer them any time.

The company sent a technician to our home in July of 2015. We are still waiting for our meter to be installed. The panels were installed weeks ago. They look good but now power is being generated for our use. They have promised but not delivered exemplary customer service. They failed to pay one of the sub contractors for a time and have now settled with them. We are currently looking for a way out of this mess. Twice in the last two weeks I have called to see what the hold up is and I was told that it was up to PG & E. We were given another deadline for action, but to date have not received even return phone call.

my solar panel was installed Jan 2016. To date, I am not reaping ANY PG & E savings because Complete Solar kept hooking it up to the wrong meter. many many emails and phone calls to Complete Solar and still nothing happens. I can really get a help from someone to get Complete Solar to finish the job. Alas, I already paid them because they kept sending me bills and I thought it was done correctly last year.
