The pumping station building of Sanbao drainage project in Hangzhou is designed and constructed in strict accordance with the three-star standard of national green building. It mainly adopts a number of green environmental protection technologies, such as photovoltaic semi-transparent roof, water source heat pump, rainwater recovery, etc.

Looking up from the inside of the building, you will find that the glass roof is transparent. This is not ordinary glass, but the CdTe thin film semi-transparent modules that can generate electricity. The pv modules used in the project is developed and manufactured by Advanced Solar Power (Hangzhou) Inc., which not only keeps relatively high power generation capacity while transmitting light, but also adopts double glass insulated modules according to the requirements of building application, which can effectively prevent the corrosion of river water and extend the service life of the whole power generation system.

ASP's CdTe thin film module has high conversion efficiency and excellent power generation capacity, with strong power generation capacity, high conversion efficiency, low temperature coefficient, good weak light effect, high stability, small hot spot effect, small damage rate, uniform color, beautiful and generous features. Under different regional conditions, CdTe modules generate more than 5% and 10% more electric energy per year than crystalline silicon modules. In the era of electricity subsidies, ASP's products will bring greater returns and returns.

The above ground construction area of the pumping station project of Hangzhou Sanbao drainage project is about 7850 square meters, with 5 floors in total, and the roof area is about 640 square meters. At present, it has entered the main capping stage and is about to be completed. About 900pcs CdTe semi-transparent modules with a transmission of 20% are installed with a total installed capacity of 53kw and the power generation is about 53000 kwh per year.
