"Unfortunately my husband s company is moving us to the midwest. Even though we had a signed contract with Rick and Teresa at Sunriver Solar, they we very understanding and basically told us not to worry about it and to enjoy our next adventure. They even asked if they could help us with any of the moving stuff!!! They are a delight to work with, they do everything, they kept us up to date on what was going on, and, even though we could not work with them, we would highly recommend them. You really cannot go wrong with Sunriver Solar."

"I recently moved up to Grass Valley and have started the process of going mostly off grid. I found Spartan with a little googling. At first I thought their prices might be on the higher side, as they looked more professional and had higher end products. But after I got quoted from a couple other guys Spartan came in very fair. Mike was a wealth of knowledge on the sales side and the internal office was super organized and kept me aware of everything. There was a slight hold up from the county but Madison filled me in and I was never at a loss for info. Final project installed and it looks great! Brian and his guys came out and weâ re done in two days once the ball got rolling. Time to start seeing the savings and not to be so reliant on PG&E. Overall Iâ m really happy and glad I chose this outfit over the rest."

"We did a total remodel of my husband's family home.   It took over six months.  Our next door neighbor is Andre Johnson who is starting up his own solar panel installation out of his home.  He has been in the business for  years, but felt now was the time for him to start his own business.  After we moved in, we talked to him about solar installation...we got some other bids, but his was still the best.  He and his son did the installation, then we called the city for the inspector to come out.
This is why I am writing this review.  With the total remodel, we had a lot of city inspections, and we knew how particular they are.  The inspector came out, went up on the roof for 10 or 15 minutes.  Then he told Andre he wanted to talk to us.  We thought...this can't be good.  On the contrary....the inspector wanted us to know what an outstanding job they did.  In fact, he said he had never seen such a perfect job.  He had been to two other homes for solar installation inspection prior to ours, and neither one of them passed.  He said they were done by well known, large local companies.  He said the larger companies sub-contract out the work, so you don't get the pride of ownership kind of work that we got.
Andre has five different licenses on his business card.  I did check his CA license....#958114...and he is in good standing with the state of California.  One of the other licenses was his federal contracting license, and another one was with the State of California as a disabled vet.
If you are looking for any kind of solar panel installation, PLEASE call Andre for a bid.  I really don't think you can find a better price, and I know you won't get a better job.

"Very thorough and detailed explanation for any questions you may have. They are a great family run company, not one of those big companies that are trying to rush the entire process and installation, just to get to the next job. Recommend this company for anyone looking to go Solar to get our of those crazy ever increasing electric costs."

Solar Panels questions, answered by experts

Solar shingles typically last between 20 and 30 years, a lifespan comparable to that of traditional solar panels and standard asphalt shingles. The exact duration depends on the manufacturer and the quality of the installation. Because solar shingles are a newer technology, there is limited data on their actual long-term performance. Factors that can impact their durability and longevity include weather conditions, roof ventilation, and regular maintenance. To extend the life of your solar shingles, you should conduct regular inspections and cleaning, and make any necessary repairs as quickly as possible.

In almost every case, solar panels need to be removed to replace roof shingles. In some cases, such as solar installations where the panels are on raised platforms above the roof surface, installers may be able to install new shingles without removing the solar installation. However, to get a quality roofing installation, panels need to come off. Most roofing contractors won’t remove or reinstall solar panels as part of a roofing project, so you’ll need to contact your solar provider.

Learn about common solar blockers in your area to determine how often you should wash solar panels and the best cleaning method:

  • Soot: If you have a fireplace, soot can disperse and accumulate on the solar panels.

  • Debris, dirt, and leaves: These natural elements require light cleaning. Being close to trees or living in a desert area can cause more of these to accumulate.

  • Pollen: Areas with a high pollen count require more frequent solar panel cleaning, and sticky plant material requires a deeper cleaning.

  • Bird droppings: Bird droppings are binding and more difficult to remove. Keep this in mind if you live near a lot of surrounding trees. 

Yes, solar panel installation will require permits. The required permits will depend on where you live, as some states and cities have solar-specific permits, while others only require electrical permits to connect to the grid. In either case, it’s best to hire a reputable solar installer in your area, as a representative should handle all of the necessary permitting for you and will include the cost of the permits in your initial solar estimate.

The average homeowner needs around 22 solar panels, but the exact number depends on your monthly energy consumption. Your solar professional should size your array to offset your consumption, meaning you’ll need fewer panels if you use below-average amounts of electricity, or more than 22 if you use above-average amounts of electricity. The number of panels also depends on the output of each panel. The average is around 400 watts, but you might need more panels if you install less capable equipment. Since there are so many variables, you should have a professional size your system.
