This Video is a Walk-through Complete Guide / instructions on how to build Your own adjustable angle / tilting solar panel canopy A frame to provide shade and shelter from the elements. My design will suit a flat roof and could easily be adapted to a stand alone version for ground sited panels.
A tilting frame enables maximum solar energy capture throughout winter and summer months. The frame is fitted to a flat roof and also provides rainwater harvesting through attached guttering. We recently went through severe storms in South Devon, UK with winds over 90 miles per hour. The solar panels were not affected despite being angled at the winter sunlight level. The design of the frame has shielded our conservatory roof making it cooler in the summer months which was an added bonus. Also the canopy has removed a lot of glare making it a much more pleasant environment. The canopy also enables us to grow tomatoes for an extra month because it shields out heavy rainfall. We can also leave the door open and not worry about rain coming in. We are very pleased with the outcome and can see a definite increases in solar generation with the panels raised in the winter months. Be sure to check out my rainwater harvesting system video.
