6 FAQs about [Reflective columns of solar power station]

What is the guideline for reflectance characterisation of solar reflectors?

This guideline for reflectance characterisation of solar reflectors is published under the framework of the SolarPACES Task III: “Solar Technology and Advanced Applications”.

Can multi-reflection heliostat improve solar power tower plant performance?

A novel heliostat with solar beam multi-reflected is proposed and designed. Radiant flux distribution of the heliostat field is verified to be more uniform. Optimized heliostat field shows excellent performances in efficiency and land area. This paper proposes a multi-reflection heliostat to improve solar power tower plant performance.

How can a solar reflector be quantified?

This can be quantified by the solar-weighted hemispherical reflectance, dependent on the incidence angle. Second, the reflected sunlight needs to be directed to the receiver with minimal loss; this is quantified through the specularity of the reflector (as well as its shape which is not part of this guideline).

Why should a reflector be installed in a PV plant?

Therefore, the implementation of the reflector in existing PV plants can also give energy benefits to the users which are most useful in the power sector. The energy improved in case-II is more, when reflector and PV module are installed at the mutually optimized tilt.

Why should reflector size be specific in PV power plants?

With the reflector integration, this unused space can be further utilized and obtained net increased energy yield from the same PV plant area. The reflector size should be specific because the interrow space in the PV power plants is limited and remains constant for the whole lifespan.

Is there a reflectance measurement guideline for solar plants?

A group of experts in the field of optical mirror reflectance characterization has been working together as members of Task III to create this document of a reflectance measurement guideline for laboratory measurements. This document does not include guidelines for field measurements in solar plants.
