I had attend the seminar yesterday night, it is very  useful for us to approach the solar energy.. it is a clean & exhaustless resource in the earth.  please check the information which discussed on yesterday if you available…

According to information, Solar panel is a semi-conductor product which using  silicon as a media for solar energy to electricity. (refer to the attached info). After that all of the energy will charge and store in the batteries. Coz of the energy is a DC voltage, a inverter should be use to transfer the energy to electrical appliance voltage (AC). In addition, a charging controller is also a key component of the system which provides a batteries protection feature in order to  keep a steady energy/voltage level to the batteries.
