We designed for him a 2.925 Kw Grid-Tie System (Net-Metering Compliant).which we estimated he could achieve a monthly return/saving of approx. Php 3,000 from his existing electric bill. (Based on monthly average over the period of a year). When his solar system we generating more electricity than he was using, it would feed the excess back to the grid, earning him a subsatnatil credit on his monthly electric bill
