When your Solar System is working, you are offsetting the energy used in your home or business. The excess energy is then fed back into the grid. The more energy you use during the day and the less at night can make a large impact on your savings.
Simply, What you run during the sun hours of the day is free and you pay for electricity from the grid at night.
Generally a Residential home would sit between 30% to 50% offset. This depends on factors such as if they are home during the day and what appliances they would run during the day. Good examples to reach a higher offset would include a pool pump or an Air Con.
Business’s Generally often will reach the 100% offset quite easily. This is not uncommon and results in huge savings.
