The efficiency of solar panels in stalled at various angles — 15°, 25° and 30°, — was carried out using the polycrystalline silicon and monocrystalline silicon panels in Systems I and Ш. These panels have different output rated values, so that the results are normalized by dividing the data by the output rated value of […]

Results and discussions
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 […]
Installation of experimentalequipment
The integrated solar energy panel proposed in this research consists of shielding and solar panels. Initially, the experimental room is only equipped with the proposed shielding panels for comparing variations of the room temperature, humidity, and energy consumption of air conditioning before and after installing the shield panels. Solar energy panels are then installed for […]

Figure 1 shows the system (System I) equipped with multiple crystal silica arrays. Figure 1. Integrated photoelectrical solar panel System I of 8.58kW Figure 3 shows the system (System III) with single silica solar photoelectrical panels […]
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 […]
Solar photoelectrical system
The integrated system consists of several modules: including the solar electricity-generating module, an integrated parallel connection module to connect to the municipal power system, an emergency power supply module to convert direct and alternate currents, and a battery module to store excess energy produced during the daytime.
