Custom energy price (per kWh) Optional. Enter a price in the selected currency to override the average.

Feed-in credit (% of retail tariff)

50% Surplus energy is valued at this share of the retail price when exported.

Roof & Orientation

Roof Area (m^2)

Shading Estimate obstructions like trees or nearby buildings.

Roof Type

Flat

Gable

Sawtooth

Select the roof that best matches your site.

Tilt (degrees) Tilt is the roof angle above horizontal. Most pitched roofs are 20-45 degrees.

Roof faces Pick the closest compass direction your roof points toward. South (180 deg) maximises annual output in most of Europe.

Usage & Lifestyle

People Count Used to approximate household energy use.

Include EV charging in the analysis Adds EV driving demand to household consumption and checks how much PV covers.

Average daily driving (km) Typical commute and errand distance per day. 30 km/day suits many drivers.

EV efficiency (kWh per 100 km) Most EVs use 16–20 kWh/100 km. Adjust for your vehicle.
