How to monitor the prevailing pressure in a solar power plant?

The pressure conditions in the solar circuit have a decisive impact on the efficiency and service life of a solar power plant. To monitor the prevailing pressure, you can choose from a range of pressure gauges (111) as well as pressure sensors (PMT). The following 12 products correspond to your selection.

Why is pressure monitoring important in a solar power plant?

Pressure monitoring plays an equivalently important role to temperature monitoring. The pressure conditions in the solar circuit have a decisive impact on the efficiency and service life of a solar power plant. To monitor the prevailing pressure, you can choose from a range of pressure gauges (111) as well as pressure sensors (PMT).

What is the storage capacity of a solar power plant?

The storage capacity is currently limited to 8 h, however, in few years is expected to reach up to 12 h decreasing its levelized cost of electricity; from 14.2 ($/kWh) in 2015 to 9 ($/KWh) in 2020 .

What is thermal energy storage?

Thermal energy storage provides a workable solution to the reduced or curtailed production when sun sets or is blocked by clouds (as in PV systems). The solar energy can be stored for hours or even days and the heat exchanged before being used to generate electricity .

Does solar energy have a 'long term' storage requirement?

Solar energy has a one-day period, meaning that the ‘long term’ storage requirements is based on hours. In that context, thermal energy storage technology has become an essential part of CSP systems, as it can be seen in Fig. 13, and has been highlighted over this review.

How does a solar collector work?

These solar collectors use mirrored parabolic troughs to focus the sun’s energy to a fluid-carrying receiver tube located at the focal point of a parabolic curved trough reflector. Troughs are capable of heating up the heat transfer fluid (HTF) up to 390 °C .
