High Rised PV Power

Edinburgh Napier University have incororated photovoltaic panels onto the side of their Merchiston Campus building. The array provides electricity for a computer classroom. Plans are in progress to use the electricity to perform electolysis of water to create and store hydrogen for use in a fuel cell. Please click on the image to expand.

Low Concentration PV

Low Concentration PV

What is Low Concentration PV?

Low concentration PV (LCPV) systems have a concentration magnification ratio of less than 10X. Examples of these systems include compound parabolic concentrators, prism-based concentrators and V-troughs.

They typically use single junction silicon solar cells, have quite simple designs and often employ concentrating optics made of plastic. They are easier and cheaper to manufacture and maintain than high concentrating systems as they do not require tracking or cooling mechanisms. LCPV systems are suitable for stand-alone applications and building integration. They are capable of capturing a large part of the diffuse solar radiation, in addition to the direct component, making them particularly suitable for the climit of northern Europe.


What are the challenges for Low Concentrating PV?

LCPV systems are less efficient than other types of concentrating PV. One of the main causes is that they suffer losses from non-uniform illumination of the solar cells. To fully take into account both the direct and diffuse components of the solar spectrum, the design of the concentrating system must be tailored for the particular location. Furthermore, the integration of such devices into modular systems often results in bulky, heavy panels. 

 

How are these challenges being addressed by SISER researchers?

Researchers at Glasgow Caledonian University have developed a novel optical concentrator that can be used in a non-tracking, wall mounted, building integrated system. Careful selection of the field of view of the solar concentrator allows solar radiation to be captured throughout the year, without the requirement for mechanical tracking.
