Indicative 2026 starting points — every figure is editable in the calculator, and results depend on your own bill, roof and installer quotes.
A typical 5 kW system in Bangladesh
At around ৳ 180 per watt, a 5 kW rooftop system costs roughly ৳ 900,000 and produces about 6,833 kWh in its first year at Bangladesh's 4.8 peak sun hours a day. Your real numbers depend on your roof, shading, panel choice and how much power you use during the day — run your own figures in the calculator to see your exact payback, net savings and ROI.
How the solar calculator works
- Your setup. Bangladesh and Bangladeshi taka are pre-selected, with local electricity rate, install cost and sun hours filled in. Enter your monthly bill, or size the system from your appliances.
- Your roof. Search your address or tap “use my location”, then draw your roof on the satellite map — or just type its area. We check the system fits and read local sun hours from NASA data.
- Your results. Instantly see your payback period, net savings, ROI, system size, year-1 production and lifetime CO₂ offset — compare cash vs. a loan, and download a PDF report.
Common questions — solar in Bangladesh
How many solar panels do I need in Bangladesh?
It depends on your electricity use, roof space and local sun hours (about 4.8 peak sun hours/day here). A 5 kW system of high-wattage panels is a common starting point for a home — enter your bill or appliances and the calculator gives your exact panel count and system size.
Does Bangladesh have net metering?
Yes. Bangladesh has a national net-metering guideline for rooftop solar connected to the distribution grid (DPDC, DESCO and others), letting you offset consumption with surplus generation.
Are there solar subsidies or incentives in Bangladesh?
There is no broad national cash subsidy for grid-tied rooftop at present; IDCOL and development-financed programmes support solar in specific segments. The value comes mainly from avoiding a rising retail tariff plus net metering.
How much does a solar system cost in Bangladesh?
A typical 5 kW rooftop system costs roughly ৳ 900,000 at around ৳ 180 per watt installed. Batteries for backup add to that — the calculator prices your exact configuration.
