Php 110,000 pesos project

At the start of project having Phase-1 which composed 3 solar panels of 280watts and 1- Grid-Tie inverter unit. with daily solar activity on a 10 hours a day sunlights, the system should produce Solar Energy as 3 panel of 280watts x 10 hours could total 8400 watts or 8.4 Kwh per day. In a month of continues productions it may total to 252,000watts or 252Kwh. Based on the actual usage 456 Kwh per month will be reduced by 252Kwh from the system production could save at least 55.2% from the average consumption rate.From the above calculation 456 Kwh average usage per month is 15.2 Kwh per day consumption. At the rate of 181.99 per day x 30 = 5459.70 Pesos(Php) monthly bill.At 11.97 pesos(Php) per watt. The system daily production of 8.4 Kwh /day at 11.97 pesos = 100.55 pesos (Php) and Month saving of 3016.50 pesos(Php)Php 5459.70 minus Php 3016.50 – total savings = Php 2443.20
