Off-grid solar power system means that it doesn’t connect with public grid, it is individual. The conversion efficiency of solar cells is effected by its temperature, sunlight intensity and voltage float of battery, meanwhile, these three factors would fluctuate during one day, which would be effected by the spectrum of solar radiation, thickness of aerosphere,…
Why some price of solar street light is very low ? I think many purchasers always feel confusion that they always get low prices quoted by some sellers. Some purchasers just consider the price when purchasing solar street lights, while don’t be careful for quality. But the quality would have problem if just considering low…
Solar car is said as “future car”, it is different with traditional cars. Solar car don’t have engine, underpan, drive, gearbox, etc, it is consists of solar panels, battery and electrical machinery. Only if to control the current of electrical machinery, the solar car can be moving. There are three technical points for a solar…
Home solar power system is being pushed to develop by government and market. Government granted a lot of finance support and provide considerable subsidy to home solar system. More and more investors treat home solar project as good investment. There are many factors to push this development for home solar system. 1). The revolution of…
With the decreasing of resource in Earth, the investment cost of foundation energy is increasing, various safe problem and hidden danger of contamination are seen everywhere. Solar energy is friendly environmental renewable energy, it is bottomless of utilization, which is attracted more attention. Solar LED lighting was been developing gradually. Advantages: 1) It is very easy…
Solar energy lamp integrated, also said as integrated solar street light, is integrated with high efficient solar panel, super lifespan lithium battery, high lighting effect and smart controller, PIR body-induction sensor module, installation with guard against theft. Working Principle: Solar energy lamp integrated is via solar panel to convert sunlight into electric power, to charge…
Suniva is a manufacturer of solar cells and solar modules in United States, the company has declared to bankrupt, under its petition, United States International Trade Commission (ITC) may implement more severe trade barrier to the import of solar pv products in the Autumn of this year. This possibility makes other Countries PV manufacturers and…
Home solar system includes solar panel, solar controller, battery and inverter, etc. It use solar panel to absorb sunlight radiation, converting solar power into electric energy. Advantages: 1. Solar power resource is inexhaustible, solar panel can generate power electricity as long as sunlight exist. Moreover, power generation from solar panel is safety and reliable, cleaning…
The calculation principle of configuration for home solar power system is principle of conservation of energy, namely, the power that solar panel generates equal to consumption of total load and system wastage. Process of Calculation: 1. To confirm how much power consumption for total load per day, Q1=P*T, Q1 is Power Consumption, unit is WH;…
