Solar Panel Output FAQs
How accurate is this solar panel output estimator?
Our estimator provides results within 10-15% of professional assessments. We use location-specific solar irradiance data and industry-standard calculations. For precise figures, we recommend a professional site evaluation.
What factors affect solar panel output the most?
The key factors are: 1) Sunlight hours in your location, 2) Roof direction (south-facing is best), 3) Shading from trees or buildings, 4) Panel efficiency, and 5) Roof angle.
How much roof space do I need for solar panels?
Typically, 1 kW of solar panels requires about 100 sq ft of roof space. An average 6 kW system would need about 600 sq ft. Our calculator adjusts for your specific roof dimensions.
Can I go completely off-grid with solar panels?
While possible, going completely off-grid requires significant battery storage and usually a larger solar array than grid-tied systems. Most homeowners opt for grid-connected systems with net metering.
