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: Can all homes support solar panel systems?

• <div><p>Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof&rsquo;s orientation and pitch, and any shading from nearby trees or buildings.</p></div>

Q: Does making solar panels harm the environment?

• <div><p>Although solar panels harness the sun's power, they come at an environmental cost. The manufacturing process requires large amounts of water and involves hazardous materials like cadmium, silicon, and gallium arsenide. These materials don&rsquo;t pose safety hazards while the panels are in use but can pose a problem when left in landfills. Over time, hazardous materials can leach into the environment. This is why recycling solar panels whenever possible is better than taking them to landfills.</p></div>

Q: Can you put solar on a tar and gravel roof?

• <div><p>Yes, it is possible to install solar panels on a tar and gravel roof, but it is not the ideal roofing material for a solar installation. The process requires roof penetrations to install the solar racking system. While installers will seal these penetrations, they still increase the risk of leaks. This risk is higher on tar and gravel roofs, which are often flat. Flat roofs are more prone to leaks than sloped roofs because they can pool water during heavy rain and hold snow for longer periods, exposing the roof to more moisture.</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>
