Notes
1 System Cost is the current typical cost for the respective kilo watt hours (kwh) size of system.
2 Return On Investment estimates how long it will take for the solar system to pay for itself. Calculated by “Investment” / “Savings”
3 Solar Panel kilowatt (kw) size of each solar panel. We currently recommend 650w solar panels to give the best output for their size.
4 Daily Output kwh; calculated by “Average Number of Sun Hours” x “Panels Max Power”
3 Monthly Output kwh; calculated by “Daily Output kwh” x 30.
5 Savings. To compare the power produced by the solar system with monthly power calculated at 5 baht per kwh. Calculated by “Monthly Output kwh” x 5
