Oblicz uzysk balkonowej instalacji PV

Oszacuj the annual yield of a balcony power plant based on module power and location yield.

Wartości obliczeń

roughly typical: 800–1100

Uwaga: Ten kalkulator podaje jedynie techniczne oszacowanie. W instalacjach elektrycznych należy dodatkowo sprawdzić normy, środki ochrony, sposób ułożenia, temperaturę otoczenia, grupowanie, zabezpieczenia i dane producenta.

Zastosowany wzór

Yield = (Wp ÷ 1000) × specific yield × (1 − shading) × (1 − losses)

The calculator provides a simple annual yield estimate for mini PV systems.

Najczęściej zadawane pytania

How accurate is the yield estimate?

It's a guideline. The actual yield depends on location, orientation, tilt, shading and the inverter.

What does Wp mean?

Wp stands for watt-peak and describes the rated power of the modules under test conditions.

What is a typical annual yield?

Depending on location and orientation, roughly 800 to 1100 kWh per kWp per year can serve as a rough guideline.

Practical guidance

Oszacuj annual balcony-PV yield realistically

Module rating alone does not determine yield; orientation, vertical mounting, shading, inverter clipping and local irradiation interact.

Input values explained

Module power
Wp is module nameplate power under test conditions. It is not identical to the inverter's maximum AC output.
Specific yield
Specific annual yield is measured in kWh per installed kWp and depends on location, orientation, pitch and weather.
Shading
Oszacuj the annual yield loss caused by trees, buildings, railings or roof structures. Short partial shading can have a disproportionate effect.
Additional losses
Include inverter, temperature, cable, soiling and curtailment losses unless they are already included in the specific-yield figure.

Example: 800 Wp at 950 kWh/kWp

Use 800 Wp, a specific yield of 950 kWh/kWp, no shading and 10% additional loss.

0.8 kWp × 950 kWh/kWp × 0.90 = 684 kWh/year

684 kWh is generation, not automatically self-consumption. Exported surplus reduces financial savings.

Separate generation from savings

A household load present during daylight can use more of the same annual production and therefore save more money.

Calculation limits

  • Inverter clipping and the exact AC output limit are not simulated separately.
  • Seasonal effects, partial shading and the household load profile are simplified.
