How Solar Water Heating Works

  1. Energy from the sun is absorbed by large panels, usually on the roof of your building.
  2. The large panels convert the energy into electricity.
  3. This electricity is sent into battery cells housed within a power box we install in your building.
  4. The power box generates energy for your facility's heated water system or into a storage tank that will replenish the heated water system while being used by your employees, tenants, or public workers.
