PV Product Performance

Power (measured in watts) and efficiency (how well panels convert sunlight to electricity) are some of the most common metrics used to compare solar panel products. While they are not the only means of comparison, they are important determinants in how much electricity you can produce with a solar panel system. Metrics like power tolerance and temperature coefficient are also important ways to analyze the potential performance of solar panels under the different conditions they will experience over their lifetime. Learn how panels from different manufacturers stack up against one another in our updated article about the best solar panels on the market.

Rated Power	280

Solar Panel Aesthetics

Solar panels typically have black or blue cells, white, silver, or black backsheets, and silver or black frames. Bifacial solar panels are one exception to these rules, as they have transparent backsheets.

Cell Colors	black
Frame Colors	black
Backsheet Colors	white

Physical Characteristics

The physical characteristics of a solar panel have an impact on the product’s performance. For example, metrics like efficiency and wattage are based on the type, size, and number of solar cells used in a panel.

Cell Type	Monocrystalline
Panel Dimensions	D:35, L:1640, W:990
Cell Count	60
Connector Type	MC4

Manufacturer Location

Solar panels are made all around the world. While the bulk of solar panel manufacturers are based in Asia, companies in the United States, Canada, and other countries also produce high-quality photovoltaics.
