Technical FAQs 4

What are the dimensions of standard solar panels?

Most solar panels are about 1.5 inches thick. The typical classification of solar panel sizes is based on the solar cell size, but it's not very useful for most calculations.

How big should a commercial solar panel be?

For commercial solar panel installations, panels often range from 400W to 600W, with dimensions of approximately 195 x 99 x 3.81 cm (6.40 x 3.25 x 0.13 feet). Several factors affect the size of a solar panel, including the type of solar cells used, the desired wattage output, your property's size and the panel's overall efficiency.

Are all solar panels the same size?

If solar panels contain different numbers of solar cells, then they aren’t all the same size. As a general rule, the more solar cells a solar panel has, the bigger the size. Sixty-cell panels are usually smaller than seventy-two-cell solar panels. But things get a bit more complicated when we look at the efficiency of solar cells.

How many solar cells are in a solar panel?

The solar panels people install in their homes are made up of either sixty or seventy-two solar cells. Are all solar panels the same size? If solar panels contain different numbers of solar cells, then they aren’t all the same size. As a general rule, the more solar cells a solar panel has, the bigger the size.
