Solar simulator
Size your system in 1 minute.
Enter your location and monthly consumption to see what size system you need in kW, how many panels, how much roof area and which battery. The calculation uses PVGIS solar data for your region.
Estimated result
Yield data: PVGIS v5.3, EU Joint Research Centre (1 kWp crystalline silicon panel, 14% system loss, optimal tilt). Actual output varies with roof orientation, pitch, shading and equipment.
How does the simulator calculate?
Your region’s sunshine
We use the PVGIS annual yield (kWh/kWp) for the location you select. In Adana, a 1 kWp panel produces about 1,568 kWh per year.
Your consumption
We multiply your monthly consumption by 12 to get your annual need. If you add EV charging, we assume 17 kWh per 100 km (the midpoint of the common 15–20 kWh range).
Roof orientation
The calculation assumes a south-facing roof. Output is taken as about 15% lower on an east-west roof and about 35% lower on a mostly north-facing roof. The exact figure is measured during the site survey.
Panels and area
The reference panel is 450 Wp (1.72 × 1.13 m). We add 15% to the roof area for maintenance clearance.
Battery
For homes, the goal is to cover nighttime consumption (about half of daily consumption); for off-grid, storage for the number of days you choose. Module: 5.12 kWh LFP, 90% usable capacity.
