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.

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