Solar Panel Efficiency

Solar panels work by converting the sun’s energy into power for your home.

The average range for solar panel efficiency is 17 to 20%. A solar panel with 19% efficiency, for instance, can convert 19% of the sun’s energy into electricity.

Solar panel wattage output ranges from 310 to 420 watts, with an average per watt price of 68 to 75 cents. The number of watts indicates how much power the solar panel produces.

If you have a 320W panel and receive 5 hours of sunlight per day, the panel would produce 1,600 watt-hours, or 1.6 kWh per day (320W x 5 hours). In one year, each panel would generate 550 to 600 kWh.

High wattage output doesn’t necessarily mean better quality or performance. Choose higher efficiency if you’re working with limited space and need fewer panels to get the job done. Otherwise, standard efficiency panels work just as well — at a lower cost

Solar Panel Warranties Explained

Product Warranty

A product warranty covers physical defects or faulty manufacturing. Most solar panel brands offer at least a 10-year product warranty, while some name brands provide 20 to 25 years.

Performance Warranty

A performance warranty guarantees that your solar panel will continue to produce close to its intended output throughout the warranty period. All panels, regardless of brand or wattage, decrease output over time, but typically don’t lose more than 10-20% over 25 years.
