PV advantage compared with conventional thermal power systems, the advantages of photovoltaic power generation is mainly reflected in: ① no danger of depletion; ② safe and reliable, no noise, no pollution emissions, absolutely clean (pollution); ③ from the distribution of resources geographical constraints, can take advantage of the roof of the building; for example, PV principle areas without electricity, as well as complex terrain areas; ④ no fuel consumption and erection of transmission lines to power supply in place; ⑤ energy high quality; ⑥ users from feeling on acceptable; ⑦ PV short construction period, the short time it takes to obtain energy. PV array system can be installed in the difference between the level of the best angle roof glazing facade and roof-mounted installation for maximum power output of photovoltaic power generation projects, and using conventional crystalline silicon photovoltaic module PV policies to reduce component investment costs, often want to effect the economy is good, but this installation aesthetics in general. Wuhan is the best angle of about 30 degrees to the south in the Northern Hemisphere tilted roof, southeast, southwest, east or due west of the roof can be used to install a photovoltaic array on the roof of the south to be able to follow the optimum tilt angle or installed close to the optimum angle.
