↓₱ Reduce my electricity bill Use the hybrid inverter with solar and grid first; add a battery later only when needed. ▣ Add backup during outages Keep essential appliances running with a hybrid inverter and battery. ⌂ Plan an off-grid system Size solar and storage for limited or unavailable utility power. ▱ Check what fits on my roof Start with roof space, then estimate the practical system size. ＋ Upgrade an existing system Compare a target package or future expansion against current needs. ⚙ Design it manually Use exact kWh or a known target system size.

Step 2 of 4

Start with the information you already have.

A normal electricity bill is enough for most homeowners.

Have a Meralco bill photo or PDF?

Use the private Bill Scanner to read kWh from one or more bills, review the values, and bring the confirmed average back here.

Scan my bills

Typical monthly electricity bill (₱)i

That is enough to continue. For the first estimate, Solar Plan Lab uses an editable starting electricity-rate assumption of ₱14.30/kWh.

Adjust the electricity-rate assumption

Electricity rate (₱/kWh)i

Leave the starting assumption in place if you do not know this yet. You can replace it after seeing the first result.

Use three monthly bills for a better average

Month 1 bill (₱)

Month 2 bill (₱)

Month 3 bill (₱)

The battery-free core removes the battery breaker, battery lugs, and battery cable pair. The ATS remains in the core baseline because it can provide inverter-bypass/failover even without battery storage. Final requirements still depend on the actual installation.

Optional: add mounting, labour, delivery, and other costs

Mounting / structure allowance (₱)

Labour allowance (₱)

Delivery, permits, and other costs (₱)

These remain zero until the user enters site-specific amounts. The result is therefore a known equipment baseline, not a complete installed quotation.
