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: 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: 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>

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>

"When working around the house I noticed that my main circuit breaker panel was suffering some severe corrosion which turned out to be due to a leak coming down the main power cable. NE Renovations had gotten good reviews so I asked them and others for a quote. The NE Renovations team (I believe sub-contractors) seemed to know the most about what they were doing and also helped me take temporary measures to stop the leak. When they came back to perform the job they were very quick, clean and professional. This included replacing the interior and exterior wall penetration, meter box, main feed cable and some pieces on the circuit breaker panel. They also dealt with the town for permits and the electric company for pulling the box. Overall they did exactly what they said for the price that they quoted and I was very pleased with their service. I also used two of the Angie's List "BigDeal" coupons, which they handled without any problems. I would definitely recommend them to others.
