"Dave was responsive. He came with a crew and moved six solar panels from my second story to my first story. They did a great, clean job. Very good customer service, very responsive and answered all my questions. He definitely knows what he is doing and is very professional. I would refer him to others and will use him again!"

"Green Muscle was great to work with. They were very knowledgeable and professional. The other 3 solar companies I met with were a little pushy and quite a bit more expensive. My sales rep/project manager, Jim, was on top of everything and we actually got installed a week earlier than promised, which was a nice surprise. He handled everything, even submitting to our HOA. We also really like that they do their own installs. The system looks awesome and we cannot wait to start saving money this summer. We highly recommend Green Muscle Solar!"

"I was very happy with the service, pricing and timeliness of my new utility tied solar system which included (2) LG RESU 9.8 kW batteries for storage, peaks shaving and backup... Sun Valley Solar Solutions took care of every little detail. From the sales department to the technicians performing the install top notch work was performed. The site evaluation was informative and when it was done I felt strongly I had picked the rite company for the job. Permits was a breeze they took care of all the paper work. I signed a few docs online and then was able to keep track of the progress with the emails and phone calls from the installer, then when time to turn my system on they performed a very comprehensive walk through of the system and all it operations. Safety protocol was followed from start to finish. The best part I am making power, great warranty with an established company that will be in business for many years to come. Great Job! Sun Valley Solar Solutions. Thank you. Robert W."

"I initially had reservations about the concept of installing solar panels, but I was keen on getting an estimate and seeking professional advice. That's when I met Arvin. He provided me with a comprehensive walkthrough, clearly outlining the advantages of having solar panels. The entire process was straightforward, with each step being well-explained, leaving no room for surprises or unexpected outcomes. Now, a little over 5 months since the installation, I'm enjoying the benefits just as he promised. I want to extend my gratitude to Arvin for his professionalism and responsiveness. He was always there to address any questions I had, both during and after the installation process. Thank you, Arvin!"

Solar Panels FAQs, answered by experts

In most states, solar installers need to be licensed and insured as solar professionals, although some states don’t have specific requirements for installers. You can use our state licensing tool to check if an installer you’re considering hiring holds the proper licensing. No matter where you live, a member of your solar panel installation company must be a certified electrician to connect your panels to your home and the electric grid.

Ideally, you want to place them facing true south. This is different from what a compass shows, which is called the magnetic south. You can find true south by using an online calculator as long as you know the longitude and latitude of your property. Solar panel placement is key to maximizing the energy you generate, so this is an important step.

Professionals use the same methods to install solar shingles that they do for asphalt shingles, so you’ll often see a similar installation timeline of one to two days. The amount of time required will depend on the size and slope of your roof and the number of shingles installed. Weather conditions can delay installation, as working on a roof is unsafe during high winds or heavy rain.

Yes, it is possible to install solar panels on a tar and gravel roof, but it is not the ideal roofing material for a solar installation. The process requires roof penetrations to install the solar racking system. While installers will seal these penetrations, they still increase the risk of leaks. This risk is higher on tar and gravel roofs, which are often flat. Flat roofs are more prone to leaks than sloped roofs because they can pool water during heavy rain and hold snow for longer periods, exposing the roof to more moisture.

The average cost to install solar panels is around $27,000, with most homeowners paying between $4,500 and $54,000. These prices don’t consider the federal investment tax credit (ITC), which can reduce costs by up to 30%. The final price depends on several factors, including the size of the system needed to offset your energy consumption, the amount of sunlight your home receives, your geographical location, the type and brand of panels, labor costs, and any add-on products like solar batteries or electric vehicle (EV) chargers. It is recommended to get price quotes from at least three solar companies in your area to find the best deal.
