Introduction
Bangladesh moves towards becoming, energy security, green energy and more stability. The need for reliable electricity in the country is increasing, especially in rural and semi-urban areas. The government is also insisting on adding more renewable energy to the grid.
Solar power solutions, especially off-grid and on-grid systems, are becoming very important. These technologies use a lot of sunlight that Bangladesh gets to make clean, inexpensive and reliable electricity for homes, businesses, industries.
Iconic engineering limited as a reliable renewable energy solution provider in Bangladesh, provides tailor solar off-grid and on-grid systems to meet urban and rural energy requirements. To achieve total energy freedom or reduce electricity bills through pure metering, our solutions provide unmatched efficiency, reliability and long -term values. These systems enable energy freedom, reduce dependence on fossil fuels, and support infection in a greenery economy. Learn about the solar off-grid and on-grid systems, in which the system work, technical details, benefits, applications and this system need to know why it is perfect for the energy landscape of Bangladesh.
Solar off-grind system
The solar off-grid system is a standalone power solution operated independently of the national grid. It uses solar panels, batteries and inverters to generate, store and supply electricity even in remote areas without grid access. These systems generate electricity from sunlight, store additional energy in the battery, and supply electricity to the lodged load.
Major feature: Full energy freedom for areas without grid access or incredible grid connections.
Perfect for:
- Remote villages and landscapes
- Off-grid cottages or farms
- Backup power for critical facilities
Solar on-grid system
The solar on-grid system, also known as a grid-based system, is directly connected to the national power grid. Users allow users to consume solar energy during the day and export additional electricity into the grid through net metering, which reduces electricity bills for the user significantly. Solar generates electricity from panels and uses it for electricity as a connected load.
Major feature: Cost savings on electricity bills whi le connecting the grid for backup.
Perfect for:
- Urban Homes and Apartments
- Commercial Building and shopping malls
- Factory and Industry
Solar on-grid system works
Energy production: Solar panels generate electricity during the day.
Grid connection: The system supplies electricity in the premises; Additional power is exported to the grid.
Net metering: Users receive credits for surplus power sent to the grid, compensating for their bills.
No battery is required: Electricity is drawn from the grid at night or during low sunlight.
Solar off-grid system works
Energy production: Solar panels generate electricity during the day from sunlight.
Battery storage: Excess energy is stored in the battery for use at night or during a period of cloud.
Inverter conversion: Inverter converts DC power into AC power from solar panels/batteries for domestic or industrial use.
Independent Operations: System Utility works completely independently from the grid, providing electricity in remote places.
Backup Power: A generator is often used as an additional backup to ensure the availability of electricity during long-time lower-solid days.
Solar off-grind system workflow
Solar power generation: Solar PV panels absorb sunlight and convert it into DC electricity.
Energy storage: Store additional power for battery (Li-ion and Lifipo)
Power conversion: An inverter converts DC power into AC power to run domestic or industrial equipment.
Autonomous Operation: Ensuring uninterrupted power supply, works completely free from the grid.
Solar on-grid system workflow
Solar power generation: Solar PV panels generate electricity during daylight.
Power supply: directly provides strength to the load connected.
Grid connection and net metering: Energy is exported to the national grid, and users receive credit against their electricity bill.
Grid backup: When solar energy is insufficient (eg, at night), the electric is drawn from the grid.
