Difference Between Grid Power Supply & Solar Power Supply in Solar Water Pumping?
The variable frequency speed regulation control of the water pump according to the light intensity is the biggest difference between the solar water pumping system and the traditional water pumping system.
BREB to install 2,000 solar irrigation pumps; farmers can sell idle electricity to national grid
Bangladesh Rural Electrification Board (BREB) plans to install 2,000 solar irrigation pumps under a project — allowing farmers to sell their unconsumed electricity to the national grid. The solar power-run pumps will replace the existing conventional diesel-run machines in 21 districts under a pilot project, said officials at the BREB.

Irena: The COVID-19 has brought the off-grid PV market to a standstill
The latest annual clean energy statistics released by the International Renewable Energy Agency (Irena) show that the development of the off-grid photovoltaic market has stalled since the outbreak of the new crown epidemic in 2020.
The United Nations launched the photovoltaic solar innovation plan to accelerate the development of off-grid photovoltaics in East Africa
The Climate Aggregation Platform (CAP) of the United Nations Development Programme (UNDP) has launched an innovative off-grid photovoltaic financing program aimed at increasing the supply of electricity in developing countries, mainly in Africa.
EIA: The US will add 4.2GW of photovoltaics in the first half of 2022
The U.S. added 15 GW of power generation in the first half of 2022, according to a survey report released by the U.S. Energy Information Administration (EIA). The top three power generation technologies are wind power generation facilities (5.2GW), natural gas power generation facilities (4.3GW), and photovoltaic systems (4.2GW), followed by battery energy storage systems.
How to choose the DC Solar Pump?
This can be easily done by indicating the required max water flow for your application in cubic meters per hour, and the max pump head in meters.
Should You Prefer a DC or AC Pump?
Mainly in the market, there are 2 types of solar pumps: AC pump and DC pump. AC and DC vary in the way they convert energy from their power source into the pressurized fluid flow. Consequently, now it is clear that using a DC pump is much better than an AC pump.
How does a Submersible Pump work?
The working of the submersible pump is a little bit different than a jet pump. Because jet pumps transfer the fluid by pulling it while submersible pumps transfer the fluid by pushing it.
Norway Develops New Floating Photovoltaic System
Scientists at the Norwegian Institute of Energy Technology have recently tested a new floating photovoltaic system designed and developed by Norwegian startup Current Solar on a stretch of water in Kilinochchi, Sri Lanka.
