3 FAQs about [Photovoltaic panel questions and answers]

Should racking be grounded on a PV system?

Racking and frames should be grounded on every PV system. Convert high voltage low current to low voltage high current. Higher elevation tends to produce more current. Coating metal, not part of solar cell production. Selling products at a loss to gain market share. Load used when excess electricity is generated. Listing for racking in PV systems.

Do solar panels degrade if warranty expires?

The solar company should also give you a projection of how much the power production will degrade by the time the warranty expires. Solar panels’ productivity degrades at a median, 0.5 percent a year, according to the Department of Energy’s National Renewable Energy Laboratory.

Can you put solar panels on a old roof?

If your roof is old, the answer is no—at least not until you replace it. Asphalt shingles that are 10 years old or more should be replaced before adding a solar array on top, says Ana Almerini, a spokesperson for SolarReviews. New solar panels are warrantied to last, on average, 25 years, while most roofs are warrantied for 30 years or less.
