Classification of Cooling Techniques. The cooling of PV panels by the techniques with air as cooling medium using power for fans or blowers are categorized under active cooling of PVs by air. Such techniques are discussed below:
This increase is associated with the absorbed sunlight that is converted into heat, resulting in reduced power output, energy efficiency, performance and life of the panel. The use of cooling techniques can offer a potential solution to avoid excessive heating of P.V. panels and to reduce cell temperature.
Passive cooling of photovoltaic panels can be enhanced by additional components such as heat sinks, metallic materials such as fins installed on the back of P.V. to ensure convective heat transfer from air to panels . The high thermal conductive heat sinks are generally located behind the solar cell.
In this field, the most preferential cooling technique is passive cooling with a 48.13 % followed by active cooling 45.00 %. Passive cooling techniques are primely go for because of not requiring any external energy input to cool PV panels as the main reason.
Additionally, conducting an experimental setup study that incorporates PV panels equipped with an automatic spray cooling system, PV panels with heat sinks, PV panels with evaporative techniques, and standard PV panels would facilitate a comprehensive comparison of these passive cooling techniques under consistent weather conditions.
