Q: Will solar panels void my roof warranty?

• <div><p>In most cases, installing solar panels will not void your roof warranty. To keep roof warranties intact, check your written warranty or call the manufacturer to ask about clauses regarding roof penetrations. You can also protect yourself by getting written approval or a modified warranty that specifically allows the solar installation type you&rsquo;re planning. Then, hire a professional solar installer that follows roofing manufacturer instructions and protects the roof during installation.</p></div>

Q: Do solar panels cause mold on the roof?

• <div><p>It&rsquo;s possible that installing solar panels can lead to mold on the roof. The panels themselves are not the issue. Problems caused by improper installation&mdash;such as roof leaks and mounts that aren&rsquo;t sealed properly&mdash;can cause mold. Another potential cause of mold is debris accumulation under panels, which can trap moisture. If you live somewhere with extreme snow, rain, or hail, your home could be more prone to mold.</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>

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 many solar panels does it take to run a refrigerator?

• <div><p>On average, a typical fridge uses 115 kWh per month. With eight hours of sunlight per day, a 100-watt solar panel can produce 30 kWh per month. This means you&rsquo;ll need at least four dedicated panels to power the refrigerator with solar energy. Consult with a solar power specialist to get a more accurate estimate.</p></div>

They handle the entire process and make it real easy for you. I just had a great conversation with the rep discussing financial plausibility and next thing I had panels. Best part is the fixed rate for fixed amount of wattage. Enough of pesky utility hikes.

"Yellowlite did a great job. They were competitive against other solar installers, and then offered an end of the year discount that made them the winning bid. Gross cost was $2.53/W, and I will get 26% back as a tax credit. It took ~8 weeks from signing contract to install, and installation took 3 days for the electrician, 1 day for rooftop crew. They were very flexible and great to work with. For example, instead of routing conduit on the roof to connect two separate panel sections, I asked them to go through the attic, and they made the change without a second thought. The quality was great, and the electrician took his time to make the installation look good. The city inspector didn't spend much time looking at the system once he knew it was YellowLite--he was already familiar with their quality. Although the final 20% was earned for them upon startup, I did have to chase down permitting status with the utility, but only lost 1.5 weeks of solar (in cloudy February)."
