Solar planning checklist for load, roof and backup

Prepare your electricity consumption records, roof space details, and outage backup priorities before requesting a solar quote.

1. Gather 12 months of electricity consumption

Your monthly kWh units across summer peak and winter baseline months determine whether a 5 kW, 10 kW, or larger array matches your annual offset goal. Checking a single winter bill often undersizes a system when summer air conditioning starts.

2. Match system sizing to NEPRA 2026 Net Billing vs. Hybrid backup

Under NEPRA (Prosumer) Regulations 2026, new IESCO solar connections credit exported units separately at the National Average Energy Purchase Price (Rs 8.13/unit NAEPP base) while grid imports remain billed at full slab rates (~Rs 37–55+/unit all-in). That makes daytime self-consumption and Hybrid LiFePO4 battery shifting far more valuable than oversizing an array purely to export units.

An on-grid system shuts down during grid outages for anti-islanding safety, whereas a Hybrid inverter with lithium storage powers essential evening circuits (fans, fridge, lights, WiFi, or an inverter AC) using stored afternoon solar energy.

  • Check whether your existing meter already has a grandfathered pre-Feb 9, 2026 1:1 agreement (S.R.O. 547(I)/2026)
  • Avoid unapproved capacity expansion on legacy 1:1 contracts that could reset terms to a 5-year Net Billing agreement
  • Pick inverter protection ratings (IP21 indoors vs. IP65/IP66 outdoors) suited to mounting exposure
