5kW Solar System Price in Bangladesh (2026)
A 5kW rooftop solar system is the most popular size for Bangladeshi homes — big enough to cut most of a typical family's electricity bill, small enough to fit a standard roof. In 2026, a complete on-grid 5kW system from BD Solar Power costs BDT 275,000–350,000 installed, with most homes recovering the investment in 3–4 years.
This guide covers exactly what you pay for, what changes the price, how much you can save each month, and how to check if 5kW is the right size for your home.
How much does a 5kW solar system cost in Bangladesh in 2026?
| System type | Typical installed price (2026) | Best for |
|---|---|---|
| On-grid (net metering) | BDT 275,000–350,000 | Homes that want the fastest payback and can export surplus power to BPDB |
| Hybrid (battery-ready) | On-grid price plus battery cost | Homes that want backup during load-shedding and outages |
| Off-grid (with battery bank) | Higher than hybrid; sized around your nightly load | Remote sites with no reliable grid connection |
Prices are for fully installed systems — not kit-only. The final figure depends on your roof, components and how quickly you want to pay it back. A free site survey gives you an exact, itemised quote.
What's included in the price
- 10–11 solar panels with mounting structure (≈ 5,000 watts total)
- Grid-tied or hybrid inverter with monitoring
- DC cabling, breakers and surge protection
- Installation, wiring and testing by our own team
- Net metering application support with BPDB
- 25-year panel performance warranty
What changes the price
- Component tier — economy panels and inverter versus premium brands
- Panel technology — monocrystalline panels cost a little more and perform better in heat
- Battery storage — the single biggest price factor if you want backup
- Roof type and height — tin, concrete and multi-storey roofs need different mounting
- Cable runs and meter position — longer runs to your meter add cost
- Net metering work — bi-directional meter changes required by BPDB
How much can a 5kW system save per month?
A well-installed 5kW system in Bangladesh generates roughly 450–600 units (kWh) per month on average across the year. If most of that replaces grid electricity you would otherwise buy at retail rates, most homes save — estimate, depends on your usage and tariff — roughly BDT 5,000–8,000 per month.
Three things decide your actual number:
- How much you consume when the sun is shining — daytime-heavy homes save the most.
- Your tariff — higher slabs make every solar unit more valuable.
- Surplus exports — under net metering, extra units are credited, and the new Tk 10.50/unit incentive pays you for surplus power for three years. See the Tk 10.50 incentive details.
Payback period and long-term returns
At current prices, most 5kW systems pay for themselves in 3–4 years. Panels keep producing for 25+ years, so you are looking at two decades of near-free electricity after payback — before counting electricity tariff rises, which make solar savings grow over time.

Is 5kW the right size for your home?
As a rule of thumb, 5kW fits homes using roughly 500–700 units (kWh) per month. Check these before deciding:
- Roof space: around 300–350 sq ft (28–33 sq m) of shadow-free space
- Daytime usage: air conditioners, water pumps, fridges and appliances that run during the day
- Connection: single- or three-phase — both can support 5kW; your survey confirms
- Shading: trees, water tanks and taller buildings matter more than roof size
- Future plans: want an EV or a new AC later? Consider going bigger now — see the full 2026 cost breakdown.
- Compare sizes: see the 3kW and 10kW price guides.
We survey every roof for free before quoting, so you'll know your exact usable capacity before you commit.
What you get at each budget tier
Economy — proven panels and a reliable grid-tied inverter. Fastest payback, lowest upfront cost. Best if budget is the priority and your roof gets good sun.
Standard (most popular) — higher-efficiency monocrystalline panels and a premium inverter with monitoring. Better performance in high heat, stronger warranties, still a 3–4 year payback.
Premium — top-tier panels and inverter, optimised string design, extended warranties and monitoring. Best for large homes, commercial roofs and maximum production per square foot.
Every tier is installed by our own team with the same workmanship and the same net metering support — the difference is component quality and production.
Financing a 5kW system
You don't have to pay the full amount upfront. Bank solar loans and EMI plans in Bangladesh currently start around 8–9% interest, and the monthly instalment often costs less than the electricity bill the system replaces. Read the full rundown of solar financing and EMI options, or ask us during the survey — we'll connect you with the lenders we work with daily.
Net metering: get paid for surplus power
Net metering lets your system export surplus electricity to the grid instead of wasting it. Under BPDB rules, systems up to 100kW can apply — 5kW comfortably qualifies. You keep consuming solar first; anything extra is exported and credited to your bill, with the additional Tk 10.50/unit incentive for surplus rooftop power (install by 28 February 2027 to lock in the rate).
We handle the application, the bi-directional meter coordination and the paperwork. Full process: net metering policy guide.
Frequently asked questions
How much does a 5kW solar system cost in Bangladesh in 2026?
Most installed on-grid systems cost between BDT 275,000 and 350,000. Hybrid systems with battery backup cost more. The exact figure depends on components and your roof — a free survey gives you a fixed, itemised quote.
How many units does a 5kW system generate per month?
Roughly 450–600 units per month averaged across the year, with the highest output in the dry season (November–April) and lower production during monsoon.
Is 5kW enough to run an air conditioner?
Yes — a 5kW system covers typical household loads including one or two 1.5-ton inverter ACs running mainly during daylight hours. If you run multiple ACs through the evening, consider hybrid with battery or a larger system.
What's the payback period for a 5kW system?
Most homes reach payback in 3–4 years, based on current prices, tariffs and net metering credits. After that, production is effectively free electricity for the life of the system.
Should I choose on-grid or hybrid?
Choose on-grid if you want the fastest payback and stable grid supply. Choose hybrid if outages are a concern or you want backup for evening loads — it costs more upfront but adds resilience.
How much roof space does a 5kW system need?
About 300–350 square feet of shade-free area. Tin, concrete and sloping roofs all work; the survey confirms usable space and the best panel layout.
Does a 5kW system qualify for net metering?
Yes. BPDB net metering covers systems up to 100kW. Your total 5kW output can be consumed on-site, with surplus credited against your bill.
