A Solar Power Computerized Platform for Energy-Saving Management of Green Building

Among all kinds of renewable energy, solar energy is the most accessible and inexhaustible that can be applied unconditionally and has the least impact on the environment. We selected Beitou Library in the northern Taipei as the site to simulate the output energy of Photovoltaic panels (PV panels), since the building passed the Diamond Certification set by Taiwan Green Building Rating System (EEWH). The simulation was divided into two different angle settings: one set with a fixed angle for the whole year, and the other one with angles varied in certain time period. Results showed that in Taipei, when the set angle of solar panel was fixed, the output energy of Photovoltaic panels (PV panels) was the biggest when the set angle was 16 degree. In the situation of the variable angle setting, the shorter the cycle of angle variation, the lager the output energy of PV panels was.
