ON-GRID SYSTEMS

(NO BATTERIES)

​

With a little management, you can utilise the 7 hour sunshine period to the maximum.

By running the pool pumps, using the air conditioners and any other appliances that use a lot of power during this period, monthly bills can be significantly reduced, typically by 70%.

​​

(With a 10KW 3Ø On-Grid system....~259,000 THB)

​

If the monthly bill was 7000 THB, a saving of 4,900 THB can be made.

This equates to a payback period of 4.5 years.

(Note: this time frame will decrease as the price of electricity increases).

HYBRID-ON-GRID SYSTEMS (WITH BATTERIES)

​

With these systems, if correctly designed, the monthly electricity bill can be very small.

Typically 100 - 300 THB.

​

(With a 10KW 3Ø Hybrid On-Grid system.....~459,000 THB)

​

If the monthly bill was 7000 THB.

This equates to a payback period of ~6 years.

(Note: this time frame will decrease as the price of electricity increases).
