Summary

Summary: 
A Turkish engineering company active in fluid mechanics, microchannels, and heat transfer, developed an affordable - passive photovoltaic panel cooling technology providing energy efficiency and panel lifetime extension. The technology decreases temperatures of photovoltaic panels which leads to a dramatic increase in efficiency of electricity generation and an increase in technical lifetimes of photovoltaic panels. The company seeks for license partners.

Description

Description: 

It is known that nominal efficiencies for the photovoltaic panels are lower than 20% and it can be increased using efficient cooling techniques.
The Turkish energy company active in Ankara, established by researchers and professors created a novel low-cost cooling system for photovoltaic panels resulting in energy efficiency and extended panel lifetime. The cooler is formed of mini channels, adhered right behind the photovoltaic solar cell. The mini channels and the micro-channels have higher heat transfer capability as they have a higher ratio of the area to the volume; this feature of the cooler makes it possible to remove more heat from the cells. As a result, photovoltaic cells are cooled even more and they operate with higher efficiency. Additionally, as the thickness of the channels is smaller, the volume of the coolant inside the cooler is lower and as a result, it is lighter. The heat collected from the photovoltaic solar cells by the circulating coolant is transferred into the water container and heats up the water inside the container. Alternatively, the collected heat from the photovoltaic cells can be dissipated to the ground by buried plastic tubes. Since the temperature of the ground about 4 meters down is between 10 °C- 16°C, it is possible to transfer the heat from the hot photovoltaic cells to the ground.
The liquid coolant (water + ethylene glycol) which has lost its heat is pumped back to the cooler and this cycle is repeated. Waste energy can also be used for heating indoor places and heating of water (villas, houses, hotels, hospitals, sports facilities, offices, etc.) The technology meets both the electric and thermal energy requirements of the industry. Patent applications are made and protected by Patent Cooperation Treaty (PCT).
Potential partners are sought for exclusive or non-exclusive license agreements with the substantial transfer of know-how.

Advantages & innovations

Cooperation plus value: 
The cooler increases the cost of the panel only 20% whereas the efficiency grows at least 10%. Custom-designed mini-channels heat sink with the custom mixture of coolant liquid ensures lighter add-on with higher cooling performance on the back of the panels.

Stage of development

Cooperation stage dev stage: 
Prototype available for demonstration

Partner sought

Cooperation area: 
The company seeks for companies active in the solar power sector to transfer the know-how under a license agreement. License partners are sought among solar energy companies, photovoltaic panels distributors, trade agents, or after-sales service representatives. Initially, non-exclusive agreements are considered, but in case of a strong reputation and coverage in the target region or additional tasks offered by the potential partner such as further technological development of the system or better adaptation of the product to market needs, the company may sign exclusive licensing partnership agreements.
