Solar Efficiency

With these sturdy and attractive panels, you get a solar efficiency of 15.9 percent, which is certainly a solid percentage in the world of solar modules. These monocrystalline panels can produce a maximum power of 305 watts. They also can generate a maximum voltage of 36.6 volts and a top power current of 8.33 amps.

These are tall and somewhat narrow in width, which gives them a design that sets them apart in appearance from a number of other solar panels, but in a way that is no doubt appealing to many customers. There are 72 solar cells in each panel.

Durability

Canadian Solar provides a 10-year warranty covering its product and workmanship. You get one year of warranty coverage guaranteeing power output at 95 percent. The warranty provides 25 years of coverage with power at 80 percent.

The Canadian Solar CS6X-305M solar panels are well made and substantial, able to handle a maximum load of something such as snow up to a maximum of 113 pounds per square foot. They also can sustain impacts as significant as 1-inch hailstones flying at 52 mph.

Features

Theses solar modules can take on temperatures as miserably low as 40 degrees below zero, which is quite standard in the industry. These panels also stand up well in extreme heat with their ability to endure temperatures up to 185 degrees F. The cover materials are made of tempered glass and the frame of anodized aluminum.

These solar panels are self-cleaning. That means in most cases, with a roof that has a decent angle, they can simply be left alone once they are installed and the rain will wash away dust and dirt. However, the company suggests in its installation manual that it is a good idea to use water and something that will not scratch the glass surface, such as a sponge, to clean the panels if a significant amount of material builds up on the panels.

These panels also feature an anti-reflective surface, which boosts the input of sunlight into the panels and makes them more efficient.

Dimensions

In terms of size, these are among the taller solar panels we reviewed and have more of a rectangular shape than many others, which have a design that looks closer to a square shape. Whether that style and look suits depends on your individual tastes and how panels with this configuration will look on the roof of your house.

These solar panels are 76.83 inches long, 38.7 inches wide and 1.57 inches deep. A single panel weighs 50.7 pounds.

Summary

You get a healthy warranty, almost maintenance-free and attractive solar panels for your home when you install the Canadian Solar CS6X-305M. These panels are certainly worth checking out if you want a money-saving and well-made solar panel system for your home.
