Best return on investment
This system is designed for a small to medium residential house with average daytime use of 3KW (electricity bill 6000 -12,000 baht monthly). This system will reduce your electricity bill rather than replace it.
By eliminating expensive batteries, we are able to significantly cut the cost of the system. During daytime, a 3kW load can be powered by solar with peaks supported by PEA. Low loads will feed electricity back to PEA. Nightime will be supported by PEA.
During the daytime, you can expect an average of 20 PEA daily units of power to be supplied by the system with zero cost. This will cut your PEA bill by 3180 baht per month. System cost will be recovered in 28 months.
Note.Savings assume mounting with southern aspect, inclination equal to latitude, with no shading. Savings may be reduced by shading and sub optimal mounting angle and direction. System efficiency may reduce over time in areas with high bird population, and may require semi annual panel cleaning to restore efficiency.
