Factors should be considered while designing the system
1 ---- The power of the electricity appliance and its working hours per day.
2 ---- The efficient sunshine hours in the location.
3 ---- The proportion of the rainy/cloudy days in the location.
4 ---- How many rainy-cloudy days for the system to work normally.
5 ---- The database of the local weather report, such as sunshine hours, wind power, rainy-cloudy days, natural disaster and so on.
6 ---- The installation location should be wide, and make sure that there is no high building or other things to cover the solar panels and the sunshine.
7 ---- The nearer the location of the system is from the Power Grid, the better the system will be.
8 ---- You should take full investigation while designing the system, survey the local climatic condition, the current needs and future potential demands clearly, focus on performance, and consider energy composition, structure, cost, transportation, construction conditions, maintenance, and other conditions. System protection should be complete, and easy to operate, and the maintenance should be as little as possible.
