Problems solved by technology

Therefore, in traditional residences, in many cases, the roof surface with the solar cell power generation device cannot face the south side with the best sunshine conditions, making it the main reason for the obvious decrease in solar power generation efficiency. Installing a solar cell power generation device on the device often fails to obtain the desired amount of power generation, which will cause people who live in solar cell power generation houses to complain.

Embodiment Construction

[0048] Embodiments of the present invention described in claims 1 to 4 will be described below in conjunction with the accompanying drawings. figure 1 It shows the house J in which the solar cell power generation device 19 according to the present invention is installed. The house J of the present embodiment receives power supplied from the commercial power source 12 and also self-supplies electric power by the solar battery power generation device 19 and even reversely charges the commercial power source 12 .

[0049] The commercial power supply 12 is connected to the house J through a power line 13, and the power line 13 enters the house J through a channel 14 provided near the house J. A distribution box 15 is arranged in the channel 14, and a purchased watt-hour meter 16 for accumulatively calculating the amount of power supplied from the power line 13 to the residence J is arranged in series inside the channel 14. The watt-hour meter 17 of the power, and the external di...

Abstract

All cable output from solar cell faceplates setup on building roof are led in termination rack connected to output sockets in building. Connection cables are connected to output sockets at backside. Each solar cell faceplate is connected in serial, and cables to convectors are connected to two ends of the said cascaded solar cell faceplate. Thus, connection and operation at backside of solar cell faceplate can be omitted. Zone of aeration for heat release is formed between solar cell faceplates and faceplates of building roof. Cables through the said zone of aeration are collocated to house from roof. House is faced to south within 30 degrees in order to guarantee stable power supply. Advantages are: easy of installation and reconditioning, preventing lowered conversion ratio, not easy influenced by environment and providing stable electrical power.

Description

technical field [0001] The present invention relates to a solar cell power generation device, and in particular, it can be used as a home-use power generation device such as a house or an office. Background technique [0002] In modern life, electricity is used in lighting, heating, power, air conditioning, heating and other work. Usually, electric power is supplied by public commercial power supply, and at most, it is used together with a generator for emergency use in a hospital or the like. However, in recent years, along with the improvement of the power generation efficiency of solar cells and the reduction in price, general houses, offices, etc. have also adopted self-power generation from sunlight. [0003] Conventionally, solar cells used in solar home power generation have been provided as panels of predetermined specifications, and when installed on a roof to receive sunlight, a predetermined number of panels have been arranged. Furthermore, an appropriate number...
