There are 3 types of solar power systems. The differences lie in the application scenario that is unique to you.

On-Grid System

This type of system is used to generate electricity for direct use or for sale to the Municipal Electric Authority (MEA) or the Provincial Electric Authority (PEA). Power generated from solar system is directly fed into the main distribution board (MDB) and is used within the home or business facility. Excess electricity is then fed into the grid. The excess electricity may be sold back to the electric authority under the net-metering program.

Another form on-grid system is where the electricity generated is directly routed to the grid without being used by the at all. In this system, power from the solar system never enters your home and all power is sold to the electric authority.

Suitable for customers who:

  • Have obtained the rights to sell electricity to the electric authority
  • Do not want the hassles of battery
  • Use electricity during the daytime when the solar power system is active e.g. home office, businesses, and factories
  • Live in areas where grid stability is good

 

Off-Grid System

An off-grid system is one in which the solar system is used to charge a battery bank that is large enough for the target load of your house or workplace. Power is then drawn from the battery into an inverter which converts direct current (DC) electricity into alternating current (AC). With a properly sized solar array and battery bank, it is possible to design the system to last 1, 2, 3 or even more days.

_Off-Grid Solar System

Suitable for customers who:

  • Have no access to the grid
  • Want to have complete energy independence
  • Do not have the rights to sell electricity to the electric authority
  • Do not mind investing in new battery banks every 5-10 years

 

Hybrid System

This system combines the best from both on-grid and off-grid systems. Solar power is used to charge a battery bank which can be sized as required. Electrical appliances in your home or office then draws power from the battery bank via an inverter which converts direct current (DC) electricity into alternating current (AC). However, in the event that you consume more power than the batteries can provide, the appliances seamlessly draw power from the grid. Any excess power is sent to the grid.

_Hybrid Solar System

Suitable for customers who:

  • What to have the best of both worlds
  • Want to the solar generated power at night when the sun is down
  • Do not mind investing in new battery banks every 5-10 years
