Solar Savings Calculator
This calculator converts your current electricity bill into an indicative solar capacity and shows what that capacity could save you each month, each year and across the life of the plant.
Indicative savings estimate
Estimated monthly saving
₹4,480
Estimated annual saving
₹53,760
Indicative 25-year saving
₹18,08,515
Matched system capacity
~4.8 kW
Based on approximately 563 units per month at an indicative ₹8 per unit, with an assumed 3% annual tariff escalation. Over 25 years this also avoids roughly 119 tonnes of CO₂.
What this calculator assumes
From bill to capacity
Your monthly units are the starting point. Where you do not know them, we infer units from your bill using an indicative effective tariff for your consumer category, then size a capacity that matches annual consumption.
Why savings grow over time
Electricity tariffs have historically moved upward. The 25-year figure applies an indicative 3% annual escalation alongside a conservative panel degradation allowance, so it reflects a realistic rather than flattering trend.
Roof area matters
Plan for roughly 80–100 sq ft of shadow-free roof per kW. Where available area limits capacity, savings are capped by what the roof can physically carry — an assessment tells you where that line falls.
Environmental value
Alongside rupees saved, the tool shows approximate CO₂ avoided over 25 years using an indicative grid emission factor for India.
