Solar Panels questions, answered by experts

Solar batteries can be a great investment to help maximize your solar savings and make your system and home more valuable, but they’re most beneficial to customers who don’t have access to net metering. If your state or energy provider doesn’t provide net metering, batteries can be a great way to offset consumption even when your panels aren’t producing power. They also come with the added benefit of providing electricity through blackouts, so they’re valuable in areas prone to severe weather that could cause frequent blackouts. Your installer can help you decide if batteries are worthwhile.

Most solar panels last 25 to 30 years and have a warranty to match. Over time, you’ll see a diminishing electrical output. This is normal wear, but certain things can hasten solar degradation. These include heavy rainfall, high temperatures, constant humidity that corrodes the frame, and cracks or chips in the glass.

Solar well pumps range from needing 200 watts of power to as much as 12,000 watts for heavy-duty pumps. Since the most common and cost-friendly solar panels are 100-watt panels, you’ll need between two and 12 panels. The average is between two and eight panels for standard pumps. Based on the average cost of solar panels ($1 to $1.50 per watt), you’d pay between $200 and $1,800 for your well pump solar panels—not including installation.

It’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—such as roof leaks and mounts that aren’t sealed properly—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.

While you can minimally overshoot the number of solar panels you need for your home, it's not smart to go too far. Not only is the extra cost unnecessary, but your state may put caps on how much energy your home can produce and send back to the grid. It is always best to work with a solar energy professional to determine the best system size for you.
