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.

想請問想寫比邊個. 你係 informer 定係 questioner. 我假設你在 seminar 見到 supplier, 佢同你講左個 solar power system, 你又有興趣, 想知多一些.

It was a great seminar last night. The solar energy was told to be clean and renewable resource on Earth. I should thank you once again for our extra discussion after the seminar.

However solar power is so new to me, I would like to verify once again and make sure that I have fully understood what a solar power system is.

A Solar panel that collects and channels the solar (electro-magnetic) energy into electrical form, is made up of silicon semi-conductor cells. The collected electric charge will then be stored in a battery. The battery is protected and maintained by a charging controller. At last a voltage inverter is used to convert the stored energy which is in the form of DC to AC for energy supply to the home appliances.

thks saltiwet.... ...........
it is a great for me to learn your english.... can I ask you again directly once i have english problem?
