While a solar water geyser inherently utilizes solar energy for heating, integrating it with the electricity grid offers operational flexibility. In such a setup, the solar water geyser serves as the primary heat source during sunny hours, significantly reducing or eliminating the need for electrical heating. If the system includes an electric backup element, it’s connected to the grid as a secondary source. This grid connection ensures hot water availability even during periods of low solar radiation. Unlike grid-tied solar photovoltaic systems that export excess electricity, the primary advantage here is the reduction in electricity consumption for water heating, leading to lower electricity bills. Smart controllers can further enhance this by intelligently managing the use of solar energy and the grid-powered backup to maximize efficiency and minimize energy costs.
