Engineering you can trust, energy you can see

Electrical and rooftop solar engineering

Substations, panels and wiring for industry and buildings, and solar for homes, shops and factories — one engineering team across Bangladesh.

Panels power your building and charge a battery. The battery keeps key loads running in load-shedding; the grid fills any gap.

Rooftop solar

Which solar system is right for you?

The difference is simple: does it have a battery, and is it connected to the grid?

How solar works
SunSolar panelsInverterHomeBatteryGrid / meter
Best for lowering your bill

On-grid

Connected to the grid, no battery. Lowest cost per unit; can earn from net metering. Switches off in a power cut for safety.

SunSolar panelsInverterHomeBatteryGrid / meter
Best for saving and backup

Hybrid

Grid plus battery. Saves on the bill by day and keeps key loads running during load-shedding.

Best where there is no grid

Off-grid

Panels and battery only. Fully independent; battery size decides how long it runs.

Why BD Electrical

One engineering team for power and solar

We come from substations, HT/LT panels and industrial wiring. The same engineering discipline goes into every panel, wiring job and solar system.

  • Power-sector background

    Experience with substations, switchgear and utility projects.

  • Safety first

    Correct cable sizing, protection and earthing, not shortcuts.

  • Honest numbers

    Estimates show their assumptions; prices list what is included.

  • Bangla and English

    Clear explanations and documents in your language.

How it works

From first call to handover in four steps

  1. 1

    Talk to us

    Tell us about your site and load, or use the solar calculator for an instant estimate.

  2. 2

    Site survey

    An engineer checks the site, load and wiring, then gives a clear, exact quote.

  3. 3

    Installation

    Our team installs, wires and tests everything safely.

  4. 4

    Service

    We hand over, explain the work and stay available for support.

Net metering

Sell your extra solar power to the grid

Under the Net Metering Guideline 2025, homes, shops and factories can connect rooftop solar to the grid and be paid for the extra power they export.

Questions

Common questions

What electrical work do you do?
Substations (33/11 kV), HT/LT panels and switchgear, internal wiring, prepaid meters, automation (PLC/SCADA), generators, bus bar trunking and related civil works — and rooftop solar.
Do you work for factories and commercial buildings?
Yes. We work for power utilities, factories and commercial buildings. Tell us the site, the load and the deadline, and an engineer will get back to you.
How do I get a quote for electrical work?
Call, send a WhatsApp message or use the contact form. An engineer checks the site, the load and the existing equipment, then sends the scope, schedule and a clear quote.
Will solar work during load-shedding?
Only with a battery (hybrid or off-grid). An on-grid system switches off when the grid is down, for the safety of line workers.
Can I sell extra solar electricity to the grid?
Yes, under the Net Metering Guideline 2025, after your utility approves the application and installs a net meter.
How much roof space do I need for solar?
It depends on the system size and panel type. The solar estimate shows an approximate area, and the site survey measures your actual usable roof.
