What is amazing about thin film solar panles is that they can be made into and shape or size and not lose much if any effect.  In other words, solar panels that are the same size and shape as roof shingles can be made.  Your roof can be fully solar, but not look much different than your neighbor’s.  No one needs to know – or even if your want everyne to know about your solar roofing because you are proud of your choice, they will know because you tell the, not because of an unsightly or diferent looking roof.
