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 this works: Enter the units (kWh) from your 3 highest electricity bills. We use Maharashtra's actual MSEDCL tariff slabs and Pune's average 5.0 peak sun hours to calculate your ideal system size.

Tip: find the units (kWh) on your MSEDCL electricity bill — use the 3 highest summer months for the most accurate sizing.

How this works: Enter the number of each appliance and typical daily usage hours. We calculate your daily load, add 20% for miscellaneous loads, then size a solar system to meet your needs.

The Math Behind the Estimate

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 →

Sizing by Appliance Load

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.
