Bangladesh tenders 72 MW of rooftop solar
Northern Electricity Supply Co. has invited bids for rooftop systems totaling 72.36 MW to be installed on nearly 1,900 public buildings under the National Rooftop Solar Programme 2025.
Bangladesh tenders 72.5 MW of rooftop solar under national program
Bangladesh’s power regulator has started accepting bids for 17 rooftop solar systems totaling 72.5 MW, marking the first government-backed purchases under the National Rooftop Solar Programme 2025.
Bangladesh revises net metering rules to expand solar
Bangladesh has updated its net metering framework for solar. The new rules aim to expand access and raise self-consumption among prosumers.
Bangladesh scraps 5.68 GW of solar
Bangladesh has canceled 5.68 GW of planned solar capacity across 34 projects after developers failed to secure implementation, power purchase or land lease agreements, raising investor concerns over policy stability.
New deep learning tech for PV inverter fault diagnosis
A team of scientists in the United States has combined both spatial and temporal attention mechanisms to develop a new approach for PV inverter fault detection. Training the new method on a dataset created in MATLAB/Simulink, the group has compared it to a series of other data-driven and statistical-based methods and has found accuracy reached 97.35%.
Bangladesh slashes import duty on solar inverters
Bangladesh has cut the import duty on solar inverters from 10% to 1% to reduce project costs and support utility-scale and rooftop PV systems under its net metering scheme.
Bangladesh begins solar module exports
Bangladesh has started exporting PV modules, with Dhaka-based Radiant Alliance Ltd. shipping 64.6 MW to US-based CleanGrid Incorporation. The company produced the passivated emitter and rear cell (PERC) and tunnel oxide passivated contact (TOPCon) modules at its 600 MW factory using solar cells from Laos and Indonesia.
Deploying floating PV on mine pit lakes, tailings ponds
Researchers in South Korea have conducted a literature review on recorded cases of floating PV plants placed on mine pit lakes and tailings ponds, both of which are byproducts of the mining industry. Looking at more than dozens of cases, they have concluded that mine pit lakes generally provide more stable environments for deployment.
Sonnex plan 500 MW solar module factory in Bangladesh
Germany’s Sonnex plans to scale the capacity of its factory in Bangladesh to 500 MW by 2028 and to an unspecified gigawatt scale by 2035.
How to assess bifacial PV system performance on sloped terrains
Scientists have developed a precursor formulation for different PV simulation tools that can help calculate the expected performance of solar farms deployed on hilly slopes. Validation tests against an experimental setup showed an error of less than 3%.
