Many solar batteries are aligned and current and voltage required can be obtained in the form of module. An inverter is necessary to change direct electricity into alternating electricity.
 Using infinite solar energy and producing electricity |
|
Unlike other plant system, it does not have an operating part, so it is a quiet, safe and
environmentally friendly system. |

| Types of Photovoltaic Plant System |
- System connection type
- It uses daytime by connecting to the electric systme outside and suupply surplus electricity to
- electric power company. It is usually installed in an advanced country with large territory and
- electric network equipped fully.
- Independent type
- It is installed in a remote place in the mountains, islands, where there is not electric system.
- It is suitable for developing countries, or large territory or a country consisting in islands.

| Advantages and Disadvantages of Photovoltaic Plant System |
|
| Advantages |
Disadvantages |
- Energy source is clean and infinte
- Possible to generate electric power as
- necessary as in a place required
- Easy to repair and maintain, possible manless
- Long life span over 20 years
|
- Power generation depends on the quantity of
- solar radiation in a region.
- Due to low energy density, large area for
- installation is needed.
- Installation place is finite and system cost
- is high.
- Initial investment cost and generation price
- are high.
