Institutional-grade renewable energy.
Solar, storage, and EV-charging infrastructure — engineered to protect your capital and deliver dependable returns.
Integra Watt Systems Inc. is a renewable-energy EPC firm delivering solar, battery storage, and EV-charging infrastructure across the Residential, Commercial, Industrial, and Utility sectors.
Backed by Formula Oil Corporation, an established petroleum corporation founded in 2004, we combine the financial discipline of the traditional energy sector with modern clean-energy engineering — built to protect our clients' capital and deliver dependable long-term returns.
Over a decade engineering utility-scale and commercial solar across the Philippines and the U.S. — experience that de-risks every project.
Standard on every project — protecting your payback period and putting our engineering on the line long after commissioning.
A dedicated after-sales team committed to attending to system anomalies within 24 hours — because downtime is lost revenue.
Clear savings, RoI, and payback projections up front, plus cloud-based monitoring after commissioning — the returns we model are the returns you track.
Enter your electricity usage and we'll size a system, estimate your savings, and let you configure storage — then request a formal quotation.
Check any recent electricity bill for these figures.
Your monthly kWh is printed on your electricity bill (often labelled "kWh used" or "Consumption").
If it only shows the amount you pay, estimate it with:
Example: a ₱15,000 bill at ₱12.50/kWh ≈ 1,200 kWh.
This rate looks unusually low. Philippine rates are typically ₱10–14/kWh — please double-check the figure from your bill.
Solar is generated during the day — this tells us how much of your usage lines up with production.
Storage in 5 kWh increments — captures daytime excess for night use, adds outage backup, and boosts savings most when you use power at night without net metering.
Updates live as you adjust your inputs.
High-yield PV systems from rooftop commercial installations to utility-scale power plants.
Hybrid backup, peak-shaving, and containerized commercial BESS for grid resilience.
AC Level 2, DC fast charging, and vehicle-to-grid bi-directional integration.
Tier-1 modules, smart inverters, mounting, and balance-of-system components.
Provinces with solar projects engineered by our founder across his career — spanning the entire archipelago.
Over a decade advancing from PV design engineer to operations leadership across four respected solar firms — spanning system design, procurement, construction, and long-term operations & maintenance.
Engineered U.S. residential and commercial systems across multiple states, and consulted for LONGi Green Energy, a global Tier-1 solar manufacturer — giving the firm a rare edge in supply-chain vetting, component selection, and quality control.
