Abstract
A system for heating water includes a first tank containing water and a heater element for heating the water, a solar panel, a control circuit coupling the solar panel to the heater element, and a second tank. The control circuit couples power to the heater element in proportion to available sunlight. The maximum temperature of the water in the first tank is higher than the maximum temperature of the water in the second tank. Water is drawn from the system through the second tank.
