  • How to get back the cost of solar power generation connected to the grid

    How to get back the cost of solar power generation connected to the grid

    Solar net metering is a smart, rewarding way to get the most out of your solar panel system. It works by sending extra electricity your panels produce back to the power grid, sometimes even letting you sell solar energy back to the grid. In return, you earn credits that can lower. Self-consumption beats exports – Maximizing the solar electricity you use directly in your home typically provides better financial returns than exporting excess to the grid, especially with time-of-use rates and battery storage becoming more common in 2025. Federal tax credit uncertainty looms –. Selling electricity back to the grid is not as easy as you might think. Each state has its own net metering policies. Whether you're new to solar or want to.
