Q: How long does it take to install solar panels?

• <div><p>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. </p></div>

Q: Should I install solar batteries along with my panels?

• <div><p><a href="https://www.angi.com/articles/solar-battery-cost.htm">Solar batteries</a> can be a great investment to help maximize your solar savings and make your system and home more valuable, but they&rsquo;re most beneficial to customers who don&rsquo;t have access to net metering. If your state or energy provider doesn&rsquo;t provide net metering, batteries can be a great way to offset consumption even when your panels aren&rsquo;t producing power. They also come with the added benefit of providing electricity through blackouts, so they&rsquo;re valuable in areas prone to severe weather that could cause frequent blackouts. Your installer can help you decide if batteries are worthwhile.</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: Does going solar really save money?

• <div><p>Yes, going solar really saves money. In fact, according to some calculations, the average homeowner who switches from electric to solar power will save almost $2,000 a year on energy costs. While buying solar panels and switching to solar can be costly up front, the savings add up over time. If you can sell back extra energy or take advantage of tax incentives, your savings can be even higher.</p></div>

Q: What’s the difference between rooftop solar panels and a solar farm?

• <div><p>Rooftop solar panels supply energy to a single household, where a solar farm can power multiple homes at once with clean energy. Residential rooftop solar panels cost more per watt with a lower project total, and those panels only service the residence they are installed on (in most circumstances). With a solar farm, multiple households can buy into the project and share the overall cost. </p></div>
