"After having some tree trimming done, we realized that our solar domestic hot water heating panel (already 18 years old) was doomed to be shaded by a growing oak tree within a few years. At the same time, the 12 year old solar/electric hot water heater started a slow but persistent leak, pointing to some sort of internal corrosion failure.  Aztec had done very satisfactory work on installing and servicing our solar pool heater, so we called on them for an estimate.  Tony (lead for services) came out and did a full review, and had several excellent suggestions on what options we had.  We decided to keep the solar panel (old, but well built and with years of useful life remaining), relocate it to the back of the house, and replace the hot water heater.  As soon as the necessary materials where on hand, Earl and his crew showed up at 8 AM and went to work.  All the tasks were completed to our satisfaction and Earl walked us through all the changes and how to best use the new systems.  The work area was left clean and clear, and all trash removed.  It wasn't cheap, but we have 20 years of experience with the value of this type of system and look forward to many more years of ample supplies of hot water from the sun.

"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."

"Joel came out to our home in Grass Valley personally to meet with my husband and I to discuss our solar options. He was patient with our many questions and willing to explain exactly what he had to offer. He realized as we chatted that we could qualify, not only for the normal government rebates, but an extra one due to medical necessity, as we store medications in our refrigerator for our son. We just signed and are excited to work with Joel and his team and our project. It is going to be awesome to save money each year on our power bills!"

Solar Panels FAQs, answered by experts

Yes, installing solar panels or a solar roof can increase your home's value by approximately 4% to 6%. For a home with a median value of $429,000, this could translate to an increase of around $17,000. A well-maintained solar installation appeals to environmentally-conscious buyers and those looking to lower their utility bills, often helping homes sell faster and at a premium in areas with high electricity rates. However, the exact increase in value depends on factors like the local real estate market, energy costs, and available solar incentives. It's also important that the system is correctly installed and maintained; an older or poorly maintained system may not add significant value, particularly if it's near the end of its lifespan. Other solar features, like panels on a shed, can also boost your home's value.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

The time it takes to install solar panels depends on the number of panels and the size of your home, but installation takes between two and three days of work. While most contractors can install the panels over the course of a couple of days, switching to solar energy can take two to three months in total. This includes the time it takes to design the system, procure the parts, obtain the permits, install the panels, connect to the main power grid, and get an inspection.

You can start narrowing your search for a reputable solar company by finding local, regional, and national companies that service your area and maintain positive reviews online. You should also check the Better Business Bureau’s (BBB) website to see if the company has complaints filed against them. Next, contact the remaining candidates and ask about installation timelines, warranty coverage, and financing options. Choose a company that offers a labor warranty that lasts at least 10 years and prioritizes cash purchases and solar loans.

You can install solar panels on a flat or pitched roof, but keep in mind that they will need to rest at a 30- to 50-degree tilt for optimal sun absorption. It costs more to install solar panels on a flat roof because you will need to install a framing system and likely hire a structural engineer. If your roof has a pitch of more than 40 degrees, it may not be a good candidate for solar panels.
