Brief Introduction of solar power supply/solar-wind power system: 1. Essential components of solar power supply/solar-wind power system: A whole system is composed of solar panels/wind power machine, controllers and storage batteries. If the output is 220VAC or 110VAC, an inverter is also needed: 1) A solar panel (solar modules) It converts radiant energy of the sun into electricity power. The cost and quality of solar panels decides most value of system. 2) A wind power machine It converts wind energy into electricity power. 3) A solar controller It controls the working state of system and protects storage battery. 4) A set of storage battery (electronic box) It is usually Lead-acid battery, which capacity depends on how much power you want to store. 5) An inverter It converts low voltage of DC to 110-220VAC or others as the system only outputs 12-96VDC directly. 2. Considered factors when a solar power supply is designed: 1) Working conditions of the supply: A. Temperature, humidity and the situation of ray radiation? B. The whole time of sunlight over a year? C. Average efficient time of sunlight per day? 2) Requirements of customer: D. The power of the system you want the supply for? E. The voltage of your system: AC or DC? F. The average working hours of your system? G. How many days you want your system continuously work if it is overcast and rainy? H. The situation of your system's load such as starting electricity? I. How many of your system's demand? According to these factors, we will design different schemes and provide relevant prices for choices. Every inquiring is welcome.
