Even though solar and electricity retailers companies are often positioned as adversaries, it is almost never that simple
Most solar installations are on homes or properties that are connected to the electrical grid and served by SP or other electricity retailers. These retailers have a wide range of friendliness towards solar installation projects in Singapore. However, almost all electricity retailers companies have some sort of arrangement to allow customers to install a solar system and connect to their electrical grid.
A common misconception is that you can go solar and sell electricity to SP and make a profit.
SP will pay a set kWh price for additional production. Net energy settlement allows you to store energy in the electric grid. When your solar panels produce more electricity than you need, that energy is sent to the grid in exchange for credits. However, TNB in Malaysia will not pay you for additional electricity production that you do not use. Solar customers use their grid connection like a bank account to "store" energy credits for later use. Many even have limits on the maximum size system that can be installed based on your historical usage for this reason. It is important to understand your electricity usage when going solar, so you understand exactly how your credit system works and any unique features or guidelines that require consideration.
