Liquid single-phase solar energy systems must be equipped with what type of tank?

Liquid single-phase solar energy systems must be equipped with expansion tanks. These tanks are crucial because they accommodate the thermal expansion of the fluid that circulates through the solar system. As the liquid heats up, it expands and increases in volume. Without an expansion tank, this increased pressure could lead to leaks, ruptures, or damage to the system components. The expansion tank absorbs the excess volume and helps maintain stable pressure in the system, ensuring its efficiency and longevity.

In many systems, it’s important to manage this thermal expansion to avoid potential safety hazards and system failures, which is why the use of expansion tanks is mandated in the design of these solar energy systems. This specific requirement aligns with best practices for maintaining system integrity when dealing with fluctuating temperatures in solar applications.
