Before Installation - What do you need to know!
1. CONSIDER THE GEOGRAPHIC LOCATION OF THE INSTALLATION
Understanding the sun’s motion relative to a site is a crucial element to predict the solar panel performance. In other words, a solar panel
located in Texas will harvest more energy than a unit installed in Canada (considering both facing south, using similar window). The same can
be said between Summer and Winter harvest performance.
As a main recommendation, installations on northern areas are recommended only for small and middle size shades (up to 48” x 60”), with
up to one cycle per day. More aspects affect the performance of solar panels and should be considered, not being possible a “one size fits all”
approach.

The Solar Panel may not be a good fit for every window. In the summer, the sun rises higher in the sky than in the winter months. The further
north, the lower the midday winter sun will be. Due the sun position, Solar panels installed facing north produce 4 times less energy than a
device installed facing south. For this reason, we do no recommend the use of solar panel on windows facing North.
