We design, install, and maintain solar power systems for homes, businesses, and rural communities across Bangladesh. That covers grid-tied rooftop systems for factories and households, off-grid Solar Home Systems and mini-grids for areas without reliable grid access, and battery backup systems for sites that need power to stay on through load-shedding or grid faults.
We're based in Dhaka but have completed projects across the country, including industrial sites in the Gazipur and Narayanganj belt, telecom infrastructure in Chattogram, and off-grid rural electrification in Sunamganj, Kishoreganj, and Netrokona. Site surveys and logistics are planned on a case-by-case basis for more remote locations.
A grid-tied system works alongside your existing utility connection and typically requires net metering approval, but has no power at all during a grid outage unless paired with a battery. An off-grid system is fully independent, generating and storing its own power for locations with no grid connection. A hybrid system combines solar, battery storage, and a grid or generator connection, which is the common setup for backup power applications.
Cost depends heavily on system size, whether battery storage is included, and site-specific factors like roof condition and cabling runs. A small residential system may cost a few lakh taka, while a commercial rooftop installation in the hundreds of kilowatts can run into crores. We provide a detailed, itemized quote after a site survey rather than a generic per-watt estimate, since shading, roof structure, and load profile all affect the final design.
Most commercial and industrial rooftop systems we've installed pay back their upfront cost in roughly 3.5 to 5 years through reduced grid bills or diesel savings, depending on tariff category and how much of the generation is self-consumed during daylight hours. Residential systems and smaller off-grid systems typically have a longer payback horizon since the primary benefit is convenience and reliability rather than pure bill offset.
Yes, several of our commercial and rural projects have used refinancing support channeled through IDCOL (Infrastructure Development Company Limited) via partner banks and microfinance institutions, particularly for Solar Home Systems and mini-grid projects. We can help structure a financing application and connect clients with participating financial institutions, though final loan approval and terms are set by the lender, not by us.
For residential and small commercial systems, we can arrange installment plans through partner financial institutions in addition to outright purchase. Terms vary by system size and the lender's own credit criteria, so we go over the available options during the proposal stage once we know your system size and budget.
A typical residential or small commercial rooftop system takes one to three weeks from contract signing to commissioning, including permitting and inspection. Larger industrial installations or multi-building mini-grids can take one to three months depending on system size, structural work required, and net metering approval timelines with the local utility.
Our engineers assess your roof or land area, structural condition, shading throughout the day, existing electrical infrastructure, and your load profile from recent utility bills where applicable. This survey determines system size, panel layout, inverter selection, and whether any structural reinforcement or electrical upgrades are needed before installation.
We plan rooftop and electrical work around your operating schedule wherever possible, and most of the physical installation work such as mounting and panel placement doesn't require shutting down operations. Any brief downtime needed for final electrical connection and commissioning is scheduled in advance and kept as short as possible.
Panels still generate power under cloud cover, though output drops compared to clear-sky days, which is why we size systems with some margin above bare minimum requirements rather than for ideal conditions only. For sites where uptime during the monsoon is critical, such as poultry farms or telecom towers, we typically recommend battery storage sized to bridge several cloudy days.
Dust, brick kiln residue, and bird droppings can reduce output if panels aren't cleaned periodically, so we recommend cleaning every four to six weeks in dry season and less frequently during monsoon when rain does some of the work naturally. We offer maintenance contracts that include periodic cleaning, inverter checks, and performance monitoring so output degradation is caught early rather than after a bill spike.
Panels we install typically carry manufacturer product warranties in the range of 10 to 12 years and performance warranties extending to 25 years, consistent with panels certified to standards such as IEC 61215 and IEC 61730. Inverters generally carry 5 to 10 year warranties and batteries vary by chemistry and manufacturer, and we go over the specific warranty terms for the equipment proposed for your system before signing.
All installations include a defect liability period during which we address any workmanship issues at no cost, and we offer ongoing service contracts beyond that for monitoring, maintenance, and repairs. Our service team aims to respond to reported faults within 48 hours for sites within our regular service areas, faster for contracted maintenance clients.
Net metering allows excess solar generation you don't use on-site to be exported to the grid, crediting your account against electricity drawn back later, typically settled on a monthly or annual netting basis depending on the utility. The application process and approval timeline differs somewhat between DESCO, DPDC, and other distribution utilities like REB, and we handle the technical documentation and utility liaison as part of grid-tied installations.
Yes, net metering is available to REB (Rural Electrification Board) customers in many areas, though local capacity and approval processes can vary more than in urban DESCO or DPDC territories. We check feeder capacity and REB's current net metering guidelines for your specific area during the initial site assessment.
For areas without practical grid access, such as haor and char regions, we design fully off-grid Solar Home Systems or community mini-grids sized to the household or facility's actual load rather than relying on net metering, which isn't relevant without a grid connection. These systems store their own power in batteries and are sized with enough margin to get through several consecutive low-sunlight days.
