Estimated Solar Results (Bhubaneswar)
These are indicative estimates only. Actual results depend on location, electricity tariff, solar irradiation, roof orientation, shading, system size and other factors.
How We Calculate Your Solar Potential
Understanding the core factors that influence rooftop solar generation and financial returns.
1. Solar Insolation
Odisha receives roughly 300 sunny days annually. We calculate an average yield of 3.8 to 4.2 units per kW per day, accounting for monsoon season variations.
2. Tariff Offsetting
Solar power offsets high-slab power rates first. The higher your current utility tariff tier, the greater the monthly savings generated by each solar unit.
3. Roof Usability
A minimum of 90 sq. ft per kW of unobstructed, unshaded roof is recommended to prevent string mismatch losses from nearby water tanks or parapet shadows.
Frequently Asked Questions
Common questions about rooftop solar estimations and system feasibility.
How accurate is this solar savings calculation?
The calculator uses standard Odisha solar insolation averages (~1,420 kWh per kWp annually) and prevalent electricity tariff tiers. Actual figures depend on physical roof orientation, local shading, weather variations, and system components.
How much rooftop space do I need for a solar system?
As a general guideline, every 1 kW of rooftop solar panels requires approximately 80 to 100 square feet of shadow-free roof area. Flat concrete roofs and sloping metal roofs both accommodate standard mounting.
What is net-metering?
Net-metering allows you to export excess solar energy generated during the day back into the grid. Your power utility credits you for these units against your electricity consumption from the grid.
Do solar panels generate power on cloudy or rainy days?
Yes. Solar panels continue generating power using diffuse sunlight even during overcast weather, though the output will be lower compared to clear sunny days.
