Solar Photovoltaic Systems that are parallel to electricity, whether MEA or PEA by area, require permission to connect to the electricity grid.
The advantage is The cost is not as expensive as the on-grid system and It can generate electricity during the day during light, thus reducing electricity bills during peak periods.

Suitable for customers:
– Can sell electricity with PEA/ MEA Electricity is used during the day. While the solar system is running, such as home offices. Business
– Live in areas where the grid is stable in area

Solar Photovoltaic Systems that is not connected to electricity. The amount of battery capacity will depend on the amount of energy demand of each house. Suitable for installation where electricity is not accessible.

Suitable for customers:
– Grid inaccessible Need for energy independence
– The company is not entitled to sell electricity to the Electricity Authority.
– It can be obtained with battery replacement every 5-10 years.

Is a mixed system that combines on-grid and off-grid systems with a battery system to reserve power for use when there is no light. In the case when there is sunlight generating more electricity than it is used, the system charges that electricity into the battery for further use. 

Suitable for customers:
– Want the best of both systems.
– Want the system to generate electricity at night.
