Renewable energy engineering

See where PV energy disappears.

A compact PV performance tool that turns temperature, shading, soiling, wiring, inverter efficiency, and uptime into a clear loss tree.

Open the model Back to portfolio

A graduate-level project that explains performance, not just sizing.

The model starts with the STC nameplate output and walks through the losses that matter in the field, turning a basic solar estimate into a more realistic performance view.

Use the controls to test how a hot site, dusty array, and modest electrical losses change the usable AC energy.

Input assumptions

System sizing

PV size Nameplate DC size for the array.

Peak sun hours Daily irradiance equivalent used to estimate output.

Module type The module coefficient changes how hard heat hits output.

Field conditions

Cell temperature Higher cell temperature reduces voltage and usable power.

Shading Partial shading, nearby obstacles, and row losses.

Soiling Dust, grime, and site cleaning interval assumptions.

Electrical losses

Wiring and mismatch Cable drop, connectors, mismatch, and small balance-of-system losses.

Inverter efficiency Conversion efficiency from DC to AC at the inverter stage.

Availability Maintenance, downtime, and day-to-day operating margin.
