home solar power system

Solar power generation system included by solar panel, batteries, solar energy controller, and solar inverter. A) Solarpanel:It is one of the highest value of the system. its function is from the solar radiation convert light into electricity, B) Solar energy controller,it is to control the system work, and to the battery up to the charging of protection, protection of a discharge. in a big place, . C) The battery: the mini system also use batteries. its function is in the light when the solar panel by the need to store electrical energy, when released at night. D) Solar inverter:output of solar energy are generally 12vdc, 24vdc, 48vdc. to be able to supply electricity 220vac of electrical appliances. Solar power system designs to be considered : 1.Where the solar power system in use?How long the sun radiating ? 2.How much will loadfrom the system? 3.The output voltages, DC or AC? 4. The system need to work every day? how many hours 5. If there is no sun , the system needs continuous supply how many days? 6.Other requirements of the system
