Can you direct me to any information on how individual buildings/co-ops/condos in NYC are using solar power? Does anyone have cells on their rooftops, etc? What is the feasibility of such an endeavor?
I don’t have recent numbers but as of November 2005, there were 45 photovoltaic (PV) projects in the city generating 1.1 megawatts of power. The feasibility depends on many things, but the biggest one is area and shading. If you’ve got a decent amount of area to put the panels and that area receives a lot of direct sunlight, then solar will probably work pretty well.
Definitely have a professional solar installer do a proper shading analysis to determine how much sun you actually get and beware of possible new shade (e.g. growing trees or new buildings). Solar One is a good resource for more information on solar power in New York.
