The Bangladesh government requires new residential, educational, medical, industrial and commercial buildings to be installed with net-metered solar systems as a prerequisite for connection to the grid. As a result, the country's rooftop photovoltaic power generation will increase significantly.

Under the new regulations, buildings with a roof area exceeding 92.2 square meters must install a net-metered solar system. Homeowners wishing to achieve single-phase grid connection must install a net metered solar system with a minimum capacity of 1 kW, while those requiring three-phase grid connection must meet the 3 kW capacity requirement. The rules also apply to schools, hospitals and charities with a roof area of at least 1,000 square feet.

The new regulations also require that industrial and commercial customers with a grid-connected capacity of less than 80 kilowatts must install rooftop photovoltaic systems equivalent to 15% of their total load. Customers with grid-connected capacity between 80 and 500 kW must install PV systems at 12% of their load capacity, while customers with load capacity above 500 kW must install rooftop arrays at 10% of their load capacity.

Existing buildings wishing to increase their grid load capacity must also comply with the same regulations by installing additional rooftop solar systems.
