THB Solar designs, installs and maintains grid-tied rooftop solar plants for factories, commercial buildings and homes in Bangladesh — including the full net metering application with DESCO, DPDC, BPDB, NESCO or BREB.
One contract covers survey, engineering, imported components, installation, utility approval and after-sales service. No handing you off to three vendors.
Grid-tied plants on factory sheds, office roofs and homes. Daytime consumption comes straight from the roof; surplus units go to the grid and sit on your bill as credit.
For RMG, textile, cold storage and food processing units where a large shed roof sits idle. Sized against your daytime load profile so almost every unit is self-consumed.
Diesel-free pumping for farms and fisheries, with VFD controllers and dry-run protection. Runs on the field, not on a fuel delivery schedule.
All-in-one solar street lights for estates, roads and campuses, plus battery-backed home systems for areas with weak or no grid supply.
Before you spend, get the numbers checked: shading study, structural load check on the roof, generation model and a bankable payback report for your board or lender.
A plant that is never cleaned quietly loses a fifth of its output. Our AMC covers scheduled washing, thermal inspection, inverter service and monthly generation reporting.
Move the two sliders. The estimate updates against Bangladesh generation data — about 120 units per kWp each month — and current tariff bands.
Indicative only. Final numbers depend on shading, roof structure, sanctioned load, tariff category and component selection — a site survey fixes all of them. Under the national net metering guideline your system may not exceed 70% of your sanctioned load.
Get this checked on siteA typical net-metered rooftop project runs 8 to 14 weeks. Utility approval is the long pole, and it is our job, not yours.
Our engineer measures the roof, checks the structure, records shading through the day and reads your last twelve bills.
Single-line diagram, layout, BOQ with named brands, generation model and a payback schedule you can take to your board.
We prepare and file the application with your utility, follow up on the technical committee and secure the sanction letter.
Modules, inverters, mounting structure and cabling arrive together. Installation is scheduled around your production hours.
Insulation and earthing tests, string-by-string commissioning, bi-directional meter installed by the utility, then handover with documents.
You get a login showing live generation. We get an alert if a string underperforms, and turn up before you notice the drop.
THB Solar is the renewable energy line of THB Engineering & Technologies Limited, part of The House of Business group in Dhaka.
RJSC-incorporated limited company with a registered Dhaka office, TIN, BIN and a paper trail for every payment you make.
Design, import, civil work, electrical work, approval and service sit with us. One number to call when something needs answering.
We model generation on your actual shading and load, not a brochure figure. If your roof does not justify the spend, we will tell you so.
Solar is a 25-year asset. Our AMC, spare stock and in-house technicians are what keep year eleven producing like year one.
