What must be done to solar energy systems regarding pressure and temperature limits?

Solar energy systems require protection mechanisms to be installed to ensure they operate within safe pressure and temperature limits. This is crucial because these systems often involve fluids (like water or refrigerants) which can expand and contract with temperature changes. Without proper protective measures, such as pressure relief valves or over-temperature shutoffs, the system could experience dangerous conditions leading to equipment failure or even hazards like explosions.

Implementing these protective mechanisms is a fundamental aspect of the design and installation of solar energy systems, ensuring not only the system's efficiency but also the safety of the environment in which it operates. This adherence to established safety standards is vital for preventing accidents and ensuring long-term sustainability of solar power technology.
