The average homeowner needs around 22 solar panels, but the exact number depends on your monthly energy consumption.

The number of panels also depends on the output of each panel. The average is around 400 watts, but you might need more panels if you install less capable equipment.

Solar shingles typically last between 20 and 30 years, a lifespan comparable to that of traditional solar panels and standard asphalt shingles. The exact duration depends on the manufacturer and the quality of the installation. Because solar shingles are a newer technology, there is limited data on their actual long-term performance. Factors that can impact their durability and longevity include weather conditions, roof ventilation, and regular maintenance. To extend the life of your solar shingles, you should conduct regular inspections and cleaning, and make any necessary repairs as quickly as possible.
