Solar Calculator FAQs

How accurate is this solar calculator?

Our calculator provides estimates based on industry-standard calculations and real-world data from our 1000+ installations. Actual numbers may vary slightly based on specific site conditions, but it gives you a reliable estimate for planning purposes.

What factors affect solar system cost?

Key factors include: System size, panel quality, inverter type, roof complexity, installation location, government subsidies, and additional components like batteries or monitoring systems.

How is government subsidy calculated?

Subsidy depends on system capacity: 40% for up to 3kW, 20% for 3-10kW (residential), and 20% for institutional systems. Our calculator automatically applies eligible subsidies based on your inputs.

What is the payback period?

Typically 4-6 years for residential systems and 3-5 years for commercial systems. This varies based on electricity rates, consumption patterns, and available sunlight in your area.
