A passive solar water heater system is designed to optimize the use of renewable energy to heat water for various applications, such as industrial processes. The optimal performance of a solar water heater system depends on the balance between the amount of solar heat received and the energy needed to heat the water. In this article, we will discuss the energy balance analysis for a solar water heater system to understand the factors affecting its performance.
The energy balance of a solar water heater system can be analyzed by considering the following three main components: collector efficiency. Collector efficiency refers to the ratio of the actual solar radiation incident on the collector to the total solar radiation available. Storage tank efficiency, on the other hand, refers to the ratio of the energy stored in the tank to the energy input from the collector. System losses refer to the energy lost due to various factors such as heat exchanger efficiency.
