When it comes to Solar Panels they are not all the same and can be graded A, B, C?

A Grade solar cells are prime flawless solar cells.

B Grade solar cells are solar cells that contain a visual flaw that does not affect the power, their price is a little lower than A Grade cells.

C Grade solar cells are those with a flaw that affects the power output, so the output power is somehow lower than A and B Grade cells, and the price is lowest. The C Grade solar cells we are selling are guaranteed to be reaching 90% of the power and efficiency rate is over 15%.

When considering to purchase Solar Panels its also worth looking at the warranty for the panels and not just the brand name. For exmaple a leading brand of Solar Panels comes with the following Power warranty;
