💡 Business Logic & Assumptions

  • Utility Tariff structure: Model behaves according to My Utility Provider's starting retail rate of ₱0.0000/kWh. Linear inflation represents fuel cost adjustments and dispatch hikes.
  • Usage Escalation: House demand increases at % annually. Capped solar PV generation causes the extra demand to be drawn completely from grid imports.
  • Battery Loss Simulation: If toggled, a 15% round-trip conversion loss decreases usable battery capacity, which is then made up by drawing from the grid.
  • Net Metering: credits excess generation sent to the grid at 60% of the active retail rate for the month.
  • Performance Degradation: Solar PV degrades annually at %, and battery storage capacity declines at % annually.
