When should a pressure reference be included in a closed loop system?
A Pressure Reference must be included within a closed loop system: when a system is completely recirculating, such as a heating or cooling system, then a pressure reference is required to define the initial pressurized condition of the closed system.
Is passive cooling a viable option for non-concentrated PV modules?
Since an external source powers active cooling, it has a stronger impact than its counterpart. However, passive cooling techniques are energy-efficient and highly reliable as they are self-driven. Hence, this approach remains viable, especially for non-concentrated PV modules.
How does PV operating temperature affect performance?
The effect of PV operating temperature on performance can be dealt at micro as well as macro levels. The short-circuit current (I s c) and open-circuit voltage (V o c) serve as indicators of the highest potential current and voltage achievable by the PV module when no load is connected.
