PVWatts Calculator
NREL''s PVWatts ® Calculator Estimates the energy production of grid-connected photovoltaic (PV) energy systems throughout the world. It allows homeowners, small building owners,
Realistic Power Expectations: Balcony solar systems typically generate 200-800W of peak power, translating to 10-30% reduction in apartment electricity bills rather than complete energy independence. A 400W system produces approximately 300-600 kWh annually depending on location and conditions.
A 400W balcony solar system typically prevents 400-600 pounds of CO2 emissions annually – equivalent to planting 5-7 trees. Over the system's 25-year lifespan, this adds up to significant environmental benefits. It's crucial to understand that balcony solar panels cannot power an entire apartment.
Balcony solar panels are compact photovoltaic systems specifically designed for installation on apartment balconies, terraces, and small outdoor spaces. Unlike traditional rooftop installations, these systems are typically plug-and-play solutions that require no permanent modifications to the building structure.
Modern balcony solar systems include built-in safety features: Size and Space: Measure available area carefully. A standard 200W panel requires approximately 10-12 square feet of space. Orientation Analysis: South-facing balconies receive optimal sunlight in the Northern Hemisphere.
