Home solar power system can be either big or small, small to one or two hundred Watt, big to
tens of kilowatts. For household, a too small system the power is not enough,
too big is very waste , which requires according each household's actual demand
for electricity to design suitable solar power system. In generally, Home solar
power generator system designed mainly to consider the following factors:
1.Where is the solar power system used?
Climate conditions across the country are not the same, there is a great difference for the sun's light conditions, the amount of solar radiation directly affect the solar panels generated electricity.
2. How much load power to be used? how many hours per day to work??
The load power refers to the use electrical power, know the working hours can calculate the power consumption a day. Such as notebook computer power is 100 watts, if used 8 hours a day, the power consumption will be 800W . Each electrical power consumption plus together, can calculate a day’s total electricity consumption.
3. How many days does it need to be powered by a solar generator for homes, if it is to meet a rainy day without sunlight?
Solar power system can not generate electricity in rainy weather, which need to save the excess power in the light time, the number of days to use in the rainy days to determine the number of batteries will be used.
4.DC output or AC output ? What is the output voltage of system?
According to the using different environment of solar power system, output current can be AC and DC, the output voltage also have many kinds. In China, all household electricity are 220V AC output.
In a word, there are some differences for components and functions of the composition of solar power system, choose what kind of specifications must consider these above factors, and you can design a suitable home solar power generator system.
