Rooftop solar deployment could drive savings in Bangladesh, according to IEEFA

This is according to figures published by the Institute for Energy Economics and Financial Analysis (IEEFA), released last week. According to IEEFA, the levelised cost of electricity (LCOE) for rooftop solar in Bangladesh is around BDT3.5-4/kWh (US$0.028-0.032/kWh), which compares favourably to the US$0.094/kWh tariff set for industries with a load of up to 5MW.

Set to take effect on the first day of 2027, the new national standards for China's PV sector are set to phase out sub-630W modules and conventional polysilicon products.

Solar Industry Insight, Which DC Fuse Is Right for Your Solar Project?

What is the difference between 10×38mm, 10×85mm, 14×85mm and 22×58mm DC Fuses? Discover how PV fuse holders and Solar MC fuse connectors protect photovoltaic systems, combiner boxes, inverters and battery energy storage (BESS) in modern DC 1000V and DC 1500V solar projects.

The Critical Role of MCB Locks in Solar Combiner Box & Distribution Box Maintenance

The NSPV Solar MCB Lockout is a professional-grade safety lockout device engineered specifically for small circuit breakers (MCBs) used in solar photovoltaic (PV) systems. Designed by NewSun PV (NSPV), this compact yet robust lockout ensures that circuit breakers remain securely in the OFF position during maintenance, servicing, or emergency shutdown procedures. The product is manufactured from high-tension aluminum alloy, providing an excellent balance of lightweight durability and corrosion resistance — a critical requirement for outdoor solar installations exposed to harsh environmental conditions. The NSPV MCB Lockout is available in a clean white finish, making it highly visible on any electrical panel, and comes in a convenient package of 100 PCS per bag with a total package weight of just 0.48 kg (0.99 lb.).

How to Choice a combiner box size? When is using fuse connector for a solar system? NSPV Fuse Good?

In photovoltaic system design, the choice between a combiner box and a fuse connector is not simply a matter of system type, such as off-grid, grid-tied, or hybrid. The real decision depends on the number of strings in parallel, the electrical architecture, the installation layout, the protection requirements, and the maintenance strategy.

For many PV projects, both solutions can work. The question is not “which one is always better,” but rather which one is more suitable for this specific system.
