Well executed rooftop solar panel installation, Some notes to people considering an install. 1. Solar panels make great snow slides and it can come off in bug chunks. We have a short flat extension over the front door and window with a walk in front, last winter that area (despite shoveling off the flat part) came loose all at once and the walk was buried under 1 1/2 ft of snowy slush. Fortunately no one was underneath it, but something to be aware of and plan for. 2. Understand how the rebates work in your State and what the tax liabilities are on rebates or payments. We have a 28 panel install and produced more than 2,000 kwHr over our usage the first year.
