Let's talk Solar

It's not just solar panels anymore, they now have many products out there "like solar asphalt shingles". Uni-Solar is one maker of this great new product. They look just like asphalt shingles. To minimize interconnects, they come in 4'x8' sheets.The product is the best when going solar. The sheets can't be cut, so you need a roof with lots of space where there is nothing sticking up out of it (vents, skylights, chimneys). The PV shingles are nailed onto the plywood sheathing of the roof, interconnections are made under the plywood. Regular asphalt shingle are used to fill in around the edges. Shingles that are used will match the existing color. The DC electricity from the shingles is then routed to a battery bank or inverter, usually a electrician is needed for that process. Solar panels and photovoltaic shingles both collect sunlight and they convert it into energy. Solar shingles, are a photovoltaic roofing material that closely resembles standard asphalt shingles.
There are many types of photovoltaic roofing products and they compliment many different roofing materials including asphalt shingles, standing seam metal roofing, and slate or concrete tiles. BIPV roofing products are produced by mfg's whose products are designed to serve both functions. As a roofing material to protect the home and as a electrical device to produce electricity. PV systems can be sized on a small scale this will produce a limited amount of energy or can be large enough to power an entire home and to send excess electricity to the utility.

 this is what it may look like.
