How It Works

Understanding Your Solar Estimate

System Size Calculation

Based on your monthly bill, we calculate your electricity consumption and recommend the optimal system size to offset your usage.

Generation Estimate

We use location-specific solar irradiation data to estimate how much electricity your system will generate monthly.

Savings Calculation

Savings are calculated based on your current tariff rate and the estimated generation from your solar system.

Subsidy Benefits

For residential systems, we factor in government subsidies - 30% for up to 3kW and 20% for 3-10kW systems.

Payback Period

The payback period shows how long it takes for your savings to equal your initial investment after subsidies.

Environmental Impact

We calculate the CO₂ emissions you'll offset each year, showing your contribution to a greener planet.

FAQ

Solar Calculator FAQs

This calculator provides indicative estimates based on average values. Actual results may vary by 10-15% based on factors like exact roof orientation, shading, local tariff rates, and seasonal variations. A detailed site survey provides precise projections.

Key factors include: roof orientation and tilt angle, shading from trees or buildings, local electricity tariff rates, consumption patterns during daylight hours, panel efficiency, and weather conditions in your area.

As a rule of thumb, you need approximately 100 sq. ft. of shadow-free roof space per 1 kW of solar capacity. So a 5 kW system would require about 500 sq. ft. of roof space.

Direct cash subsidies are primarily available for residential rooftop solar. However, commercial and industrial users can benefit from accelerated depreciation (up to 40%), GST input credits, and net metering benefits which often provide better financial returns.

Quality solar panels come with a 25-year performance warranty and can last 30+ years. They typically degrade at 0.5-0.7% per year, meaning after 25 years, they'll still produce about 80% of their original capacity.
