4.1. Advantages of sunshading board for energy-saving of building Temperature differences of the experimental building before and after installing sunshad­ing board and then the solar panel were recorded. The actual effectiveness of shading board was evaluated by comparing the indoor room temperature and the shaded spot tempera­ture with the outside temperature in order to monitor […]

Battery module

When the electric system is operated steadily, changes in the solar electricity generated and the system operation in response to variations of external conditions will be compensated by using the battery module. If the solar system produces more electricity than is needed, the excess electricity will charge the battery model, or it will be sent […]

Integrated parallel connection to municipal power system and exchanger to provide emergency direct and alternate electric currents

The electricity produced by solar panels and batteries is direct current (DC) whereas the general appliances use alternate current (DC). Hence, the solar generated DC must be con­verted into AC with an electric converter so that the electric energy can be widely supplied to household appliances. Additionally, solar electricity generation depends on the solar intensity […]

Solar photoelectrical system

The basic principle of solar electricity generation is to convert solar light with wavelengths between 0.7 to 0.9 micrometer irradiating on a semiconductor. Inside the semiconductor, negatively charged electron and positively charged electron holes will be generated and accumulated at the P-type and N-type layer regions, respectively, thus producing an electro­motive difference depending on their […]
