Costs K-Electric Difference
Difference = ALL LOADS - (SMALL LOADS + LARGE LOADS)
Difference: ALL LOADS - (SMALL LOADS + LARGE LOADS)
▪ SMALL Loads consume less power but more used, whereas HEAVY Loads consume more power but less used.
▪ To put SMALL Loads on solar and Large Loads on grid, a handsome amount of money can be avoided in payng bills
