Q: How many hours of sunlight do you need for solar panels?

• <div><p>Solar panels should get at least four to six hours of direct sunlight daily. It&rsquo;s even better if sunlight reaches panels between the peak hours of 10 a.m. and 3 p.m. This is enough to power a home, depending on your solar system&rsquo;s size and energy needs. Remember that panels will generate some power under cloudy skies or in the shade, and many systems compensate for lower sun exposure by drawing energy from the grid or battery storage.</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: Can you put solar panels on a metal roof?

• <div><p>You can install solar panels on a metal roof, but it will require some additional thought and care versus a traditional asphalt shingle roof. That&rsquo;s because heat dissipates off a metal roof differently than asphalt or wood, so you may need to space the panels further from the roof. However, a pro can help you with the details and provide a safe and effective installation. </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: Can I hook up a solar panel directly to a battery?

• <div><p>You shouldn&rsquo;t hook up a solar panel directly to a battery. That can damage the solar battery and your appliances over time. Instead, install a charge controller between your solar panel and solar battery. Charge controllers regulate voltage, prevent overcharging, and minimize the amount of electrical current to protect your battery from voltage spikes.</p></div>
