Your electricity bill, sized for solar

Confirm the three numbers printed on your electricity bill. The sheet is a planning illustration — system size, panel count, inverter class, and a savings band — and the written quotation replaces it. We install across Region 6 (Western Visayas); product support is nationwide. Use the rate printed on the bill.

Step 1 · Your bill

Add a bill photo, confirm the numbers

The photo is optional. The three numbers you confirm are what this estimate uses. The photo stays on this device until you press Send.

Find these three numbers on the bill

Total amount due (₱)Usually the largest number on the page, top right.
kWh consumedIn the consumption table — written like 412 kWh.
Your generation / delivery rate₱12.50/kWh is the planning default until you type the rate printed on the bill.

Total amount due (₱/month)

This page sizes a monthly bill from ₱1,000 to ₱50,000. A larger bill goes with a written quotation.

kWh consumed (optional)

Rate ₱/kWh

Where is this bill for?

Brownout backup wanted

If you choose backup hours, the sheet lists a battery. The payback does not include that battery. The calculator price is the grid-tied system.

ZIP code (optional — sun hours lookup)

The numbers you confirm are the ones this estimate uses. Review them before continuing.

Step 2 · Confirm & size

The payback engine, filled from the numbers you confirmed

The numbers you confirmed already fill the inputs below. Adjust anything — the system size suggests itself until you drag it. The cost per kW is a planning figure, not the quotation.

Illustrative estimate only — not a formal quote. Actual results depend on site conditions, utility rates, and your specific installation.

Planning figure, not the quotation. This rate is before 12% VAT; the total on the right adds 12% VAT. The project sheet shows a ±10% band around it. The written quotation replaces this figure.

Monthly savings—

Each solar kWh is valued at 80% of today’s rate, so savings stay below the full bill.

Illustrative estimate based on your inputs. Assumptions: 25-year panel life, 0.5%/yr panel degradation, 0.55 kg CO₂ per kWh, and every solar kWh valued at 80% of today’s retail rate — we deliberately do not project your rate to rise. The do-nothing comparison assumes bills rise 3%/yr. Net-metering exports are credited below retail and bills keep fixed charges, so realistic savings land at 70–90% of the bill. Savings stay capped at your monthly bill. Not a formal quote — actual results depend on site conditions and utility rates.

SOLAREX Project Sheet

Assumptions & scope

Sizing rules: suggested DC size is rounded up to 0.5 kW steps (0.5–50 kW), panels are 620 W tier-1 monocrystalline class (brand confirmed at quotation), inverter AC rating follows the DC/AC ratio of 1.2, and battery kWh covers evening loads at 90% usable depth. Capex is shown as a ±10% band around the planning rate (₱55,000/kW default). This sheet is an illustrative estimate, not a formal quote — the written quotation states the next step.

Step 3 · Project sheet

Your planning sheet

Built from the numbers you confirmed. Equipment class only — brands are confirmed in the quotation. The investment row is a ±10% band around the planning cost per kW, not a line-item quotation.
