How does The Solar Energy System work? Step 1: Solar Panels covert sunlight to energy Step 2: Solar Inverter converts from DC to AC electricity Step 3: Distirbutor box routes solar energy to home appliances or grid Step 4: Utility meter records Step 5: Grid rules define system permissions Solar Batteries (optional) A solar battery in its simplest form is designed to store solar energy when there is surplus being created and to use (discharge) energy in the evening or at night when the solar panels are not generating power. To take into consideration if battery storage is worth it, then you need to consider the lost feed-in-tariff, the lifetime of the battery and the total cost to install a battery. We recommended our Storage Energy System to you.
