Your electricity bill, sized for solar

Upload a photo of your electricity bill, confirm the three numbers printed on it, and get an itemised project sheet — system size, panel count, inverter, battery, savings and payback. Everything runs in your browser: the bill photo only leaves your device when you choose to send the estimate to us.

Step 1 · Your bill

Add a bill photo, confirm the numbers

The photo is optional — our engineers double-check it later. After adding a photo you can press “Read my bill with AI” to pre-fill the numbers, then confirm them.

Add a photo of your electricity bill Tap to choose a photo (JPG, PNG, WebP). Large photos are resized in your browser before sending.

Normally the photo stays on this device until you press Send. If you press “Read my bill with AI”, the photo is read on our server for the numbers only and deleted immediately — nothing is stored.

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 rateIf unsure leave our ₱12.50/kWh default — close enough for sizing.

City / province (optional — sun hours lookup)

Typed numbers stay yours to confirm — and the optional AI read only pre-fills them from your photo. Always review before continuing.

Step 2 · Verify & size

The payback engine, pre-filled from your bill

Your bill numbers already fill the inputs below. Adjust anything — the system size suggests itself until you drag it.

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

Illustrative estimate based on your inputs. Assumptions: 25-year panel life, 3%/yr bill escalation, 0.5%/yr panel degradation, 0.55 kg CO₂ per kWh, and every solar kWh valued at 80% of the retail rate due to net-metering exports being credited below retail tariff and fixed monthly charges remaining — real‑world savings typically land at 70–90 % of the retail bill. Savings stay capped at your monthly bill. Illustrative estimates only, not a formal quote — actual results depend on site conditions and utility rates.

SOLAREX Project Sheet

Generated: · Bill input: · Use case:

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 — a site survey, roof check and net-metering assessment follow before any installation.

Step 3 · Project sheet

Your solar project, itemised

Generated from the verified numbers above — equipment classes only at this stage; brands are confirmed at quotation because dealer stock varies.

Nothing here yet — confirm your bill numbers in Step 1, then press “Build my project sheet”.

Send the estimate to our team

We will review your details and confirm possible next steps, such as a site assessment or written quotation. Response times, project scope, and financing options vary; your bill photo can help clarify the estimate.
