Hybrid solar and battery storage in Lahore
Hybrid solar adds a storage decision to your panel and inverter design. Start with the appliances you need to support and their expected operating time, then review compatible battery and inverter specifications.

Panel power and battery storage use different units
Solar panels are sized in kW; battery energy capacity is rated in kWh. A 10 kWh battery does not promise 10 kW of output. The inverter, battery discharge limits and appliance starting loads also affect what the system can run.
How the calculator models storage
The estimate uses an 80% usable charging window and 90% round-trip efficiency. A new 10 kWh battery therefore has an 8 kWh charging window and can deliver about 7.2 kWh per modelled cycle, if surplus solar and nighttime demand are sufficient. Charging is limited to surplus solar; no grid charging is assumed.
Cost and capacity over time
The supplied battery budget is Rs 50,000 per rated kWh, so 10 kWh adds Rs 500,000 to the estimate. Actual pricing depends on the selected equipment. The model assumes capacity reaches 80% of its original value after 7–10 years; this is an estimate, not a warranty or automatic replacement date. Payback is based on first-year performance.
Size storage around the loads
- List essential appliances and the hours they should operate.
- Check how much daytime solar is available after direct consumption.
- Confirm compatible equipment, usable capacity and power limits in the proposal.
- Review written warranty conditions and replacement costs.
Use the calculator to change installed battery capacity, including zero for a hybrid system without storage. Export is off by default for hybrid; enable it only when approved for the connection. Compare the battery-free on-grid option alongside it.
