Self-consumption refers to using the energy generated by your solar panels within your home. Maximizing self-consumption increases your savings, as you are using free solar energy instead of buying from the grid. You can do this by running high-energy appliances, like dishwashers or washing machines, during daylight hours. Installing a battery storage system also helps store excess energy for later use. By optimizing your energy usage, you can maximize the financial benefits of your solar panel installation.
