How we compute your estimate
  • Each 1 kW of solar panels produces about 100 kWh per month in the Davao Region (about 4.2 peak sun hours a day after system losses).
  • With a battery, panels are sized to cover your full monthly use. Without a battery, panels are sized to your daytime use so less power goes to waste.
  • Battery size is based on your night-time use. We plan to use up to 90% of the battery's capacity each day to protect its life.
  • The inverter is matched to the size of your panels, not oversized. Our smallest hybrid inverter is 6 kW, so small systems still use a 6 kW unit, which leaves room to add panels later.
  • Savings count only the solar power you use yourself. Net metering credits, if approved by your utility, are not included.
  • Systems above 10 kW are custom-designed after a site visit.
