Q: How can I save money on solar panels?

• <div><p>The best way to save money on solar panels is to take advantage of <a href="https://www.angi.com/articles/am-i-eligible-energy-efficiency-tax-credit.htm">federal and state solar incentives</a>. For example, the solar investment tax credit (ITC) offered by the federal government can save 30% of your total&mdash;if you can take the entire credit, which is based on income taxes owed&mdash;or an average of around <b>$9,000</b>. You can check the Database of State Incentives for Renewables and Efficiency (DSIRE) for state and local incentives that could save you even more.</p></div>

Q: How many solar panels do I need for my home?

• <div><p>The average homeowner needs around <b>22 solar panels</b>, but the exact number depends on your monthly energy consumption. Your solar professional should size your array to offset your consumption, meaning you&rsquo;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.</p></div>

Q: Do solar installers need to be licensed or certified?

• <div><p>In most states, solar installers need to be licensed and insured as solar professionals, although some states don&rsquo;t have specific requirements for installers. You can use our <a href="https://www.angi.com/angi-license-check.htm">state licensing tool</a> to check if an installer you&rsquo;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.</p></div>

Q: How long does installing solar roof shingles take?

• <div><p>Professionals use the same methods to install solar shingles that they do for asphalt shingles, so you&rsquo;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.</p></div>

Q: How do you mount solar panels for a well pump?

• <div><p>The best solar-panel mounting system will depend on your property layout, but you&rsquo;ll typically want to try for south-facing panels to get the most sun. Roof mounting and wall mounting are both popular, but if your well setup is far away from buildings and other structures you can also set up a freestanding aluminum frame to mount your panels.</p></div>

"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!"

"BlueSel Home Solar did an outstanding job of installing my 7kW residential solar system in May of 2018! They were prompt in getting me information on the design and pricing, which was very competitive. They took care of all applications with the utility and state, as well as permitting with the town. My panels look great and we have had no issues with the SunPower panels or the SolarEdge inverter. In the first year of installation, my total electric cost was $55 ... For the year! I would highly reccommend this product from BlueSel Home Solar!"
