Yes, a well-designed and properly installed solar thermal water heater can provide hot water throughout the year. However, the system’s performance will vary with the seasons, as it depends on the amount of available sunlight. In periods of lower solar radiation, like winter, the system may not be able to cover all your hot water needs.
At Solares Energies, we typically design systems for year-round operation, often integrating them with a backup heating source. This ensures a continuous supply of hot water, even in periods of low sunlight. The backup heater can be a conventional water heater or another renewable source, depending on your preference and circumstances.
