How to Sell Electricity Back to the Grid via Solar Energy in Thailand

In an era where many organizations and the public are increasingly prioritizing energy conservation and environmental sustainability, Solar PPM provides an essential guide to the concept of selling surplus solar energy back to the national grid in Thailand.

What is “Selling Electricity Back to the Grid”?

Selling electricity back to the grid refers to generating power from clean energy sources, such as solar PV systems, and supplying the excess energy back to the public utility system. This allows system owners to generate income from the electricity they produce.
