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: Why shouldn't you put solar panels on your roof?

• <div><p>A few disadvantages of installing solar panels on your roof include the high up-front costs and the potential for increased property taxes. Installing solar panels can increase the home&rsquo;s value, which in turn can mean higher taxes. Depending on your area, you should check with your local tax offices for more information. Another potential pitfall is roof leaks from a poor installation, but this shouldn&rsquo;t be an issue if you hire a reputable company.</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: What questions should I ask a solar panel company before hiring?

• <div><p>There are a few qualifying questions you should ask a <a href="https://www.angi.com/nearme/install-solar-panels/">local solar panel company</a> before hiring them:</p><ul><li><p>Will you handle permits for the installation?</p></li><li><p>Does your total price include the equipment and labor?</p></li><li><p>How long do you expect the installation process to take?</p></li><li><p>What kind of workmanship warranty do you include with your installations?</p></li><li><p>Who should I contact if I have a problem with my system after installation?</p></li><li><p>Do you install the panels or outsource the work to third parties?</p></li><li><p>Will you file for solar incentives for me?</p></li></ul><p></p></div>

Q: Are flat or pitched roofs better for solar panels?

• <div><p>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.</p></div>

"The promo was a good lure. We discovered however that unless we brought up that we had bought this Angie's package, we were charged full price without the upgrades and add-ons. I called the person originally contacted (Julie) when I discovered the oversight. Within a week, I received the $25 visa gift card which was one piece of the package. I don't know if the other pieces will be easily added on/credited or not. Haven't seen anything. The visa gift certificate however requires me to send the partner company $2.95 shipping and handling, with a trip to the bank to get it in money order or cashier's check....really? I'm guessing they're hoping most customers won't bother.
So all in all, we like the product and the installer was awesome. Loving the service.
The package through Angie's list however I'm still waiting on to see if we got the freebies we bought.
