Cost Estimator (optional)

PV price (UGX / W) Example: 3,500 UGX per watt of panels Battery price (UGX / kWh) Example: 1.4M UGX per kWh (LiFePO₄)

Inverter price (UGX / kW) Example: 0.7M UGX per kW Balance-of-system (UGX) Rails, cables, protections, labour (editable)

Assumptions are editable. Results are indicative; final sizing and pricing depend on a site survey, roof structure, cable runs, equipment brand, and installation conditions.

What are Peak Sun Hours (PSH)?

PSH is the equivalent number of hours per day when solar irradiance averages 1,000 W/m². In Uganda, typical PSH ranges from about 5.0–5.5 depending on region and season.

Will solar run fridges and machinery?

Yes—if sized correctly. Provide your peak load (kW) and required backup hours; the tool sizes the battery bank and inverter accordingly.
