Solar Calculator
Choose your preferred method below — enter your electricity bill units or list your appliances — to get an instant estimate of the solar system size, panel count and savings for your home in Maharashtra.
How the PK Solar Calculator Works
Both methods estimate your daily electricity usage, then size an on-grid rooftop solar system for your home in Maharashtra.
1. Your Daily Usage
From your 3 highest electricity bills (or your appliance list), we calculate your average daily energy consumption in units (kWh).
2. Maharashtra Solar Math
We size your system using the region's average of 5.0 peak sun hours per day and an 80% real-world system efficiency factor.
3. Savings & Subsidy
MSEDCL's domestic tariff slabs estimate your monthly bill savings, while the PM Surya Ghar subsidy (up to ₹78,000) lowers your net cost.
These figures are indicative — your final system size, cost, and eligible subsidy are confirmed during a free, no-obligation site survey. Get your free site assessment →
What Can Each System Size Run?
A 3kW on-grid system generates roughly 12-15 units (kWh) per day in Maharashtra — enough for a small home running 4-5 ceiling fans, a refrigerator, lighting throughout the house, a TV, and a washing machine. It can also support a 1.5-ton air conditioner for a few hours a day if usage is balanced with daytime sunshine hours.
A 5kW system generates roughly 20-25 units (kWh) per day — enough for a mid-size home with a refrigerator, 5-6 fans, lighting, a washing machine, a TV, and one 1.5-ton air conditioner running for several hours daily. It's our most common recommendation for 2-3 BHK homes in Bhusawal, Jalgaon, and across Maharashtra.
A 10kW system generates roughly 40-50 units (kWh) per day — enough for a large home or small commercial space running 2 air conditioners, multiple refrigerators, water pumps, and full household lighting and appliances simultaneously. This size is also common for agricultural loads like solar water pumps.
Yes. A 1.5-ton AC draws around 1,500W and uses roughly 12 units (kWh) if run for 8 hours. On an on-grid system, the AC can run anytime — solar offsets the cost on your MSEDCL bill via net metering. If you want the AC to keep running during a power cut, you'd need a Hybrid system with battery backup sized for that load. Use the "By Appliance List" calculator above with your exact AC tonnage and daily hours for a precise estimate.
