How much does a 445w solar panel weigh?

A 445W solar panel weighs approximately 52 lbs. The dimensions are approximately 82 inches in length and 42 inches in width. Modules with this output rating are predominantly monocrystalline and usually have 72 cells or more. The efficiency of 445W solar panels varies from 15 to 22% depending on the manufacturer.

What is the efficiency of a 445w solar panel?

The efficiency of a 445W solar panel ranges from 15 to 22% depending on the manufacturer. Larger modules employ bigger solar cells, which boosts overall efficiency compared to smaller panels. The modules may also have different backsheet and frame colors, and their overall aesthetics fluctuates as well.

How long does a solar panel last?

Manufacturers typically offer a 25-year warranty for solar panels. Some, like Silfab, even offer a 30-year warranty. Solar panels are often made with anodized aluminum frames, which are lightweight, strong, and corrosion-resistant. Modern modules face less risk from potential induced degradation (PID).
