Cooling System For A Photovoltaic Module
Abstract: The major problem seen in solar panels during the summer season is the rise in the temperature of the panels. As we all know Temperature has an impact on all electronics in the system, that includes solar panels, which create less power and are less efficient at producing electricity as the temperature rises. On a summer day, the situation is not the same here. The heat within the panels already includes the electrons into an excited state. They won't involve much energy when the photons dislodge them. But still, though a solar panel can get the same amount of sunlight on a cool day or a hot day, the panels will produce more energy on a cool day. The effectiveness of solar panels does not begin to deteriorate until the temperature reaches 77 degrees. A solar panel's efficiency decreases by the pace of its temperature coefficient when the temperature rises over 77 degrees. The first step is to look for solar panels with a low-temperature coefficient, which most monocrystalline and polycrystalline solar systems have between -0.35 and -0.5. The thin-film panel can also withstand heat, with a temperature coefficient ranging from -0.25 to -0.25. They are substantially less efficient than PV panels, with an average efficiency of 11-13 percent The use of these panels also results in the reduction of efficiency over time due to the rise in the temperatures.

Specification
Cooling system for a Photovoltaic Module
FIELD OF THE INVENTION
This field of the invention corresponds to improving the photovoltaic module to produce a peak current when the module reaches its maximum acceptable temperature.
BACKGROUND OF THE INVENTION
In the previous studies there were many methods to cool the PV panel among them forced air system, sprinkler system, liquid circulation system and heat pipe cooling system were popular. These methods were used to cool the PV panel.
In the. forced air system, a blower was used to cool the PV panel from bottom to top
direction as a conventional process.
In the sprinkler system water was spared on the PV panel using sprinkler system with a
water reservoir.
In the liquid circulation system water was used as coolant to dissipate the heat from PV
panel.
The other method used to cool the PV panel was heat pipe cooling system where the
cooling system uses sealed coolant liquid. In this method the heat is exchanged between
the PV panel and heat exchange pipe is by the conventional phenomena.
So, there is a requirement of heat exchange via hybrid mode which can optimize the
performance of the PV module.
SUMMARY OF THE INVENTION
Over invention is to provide a hybrid mode of cooling PV module.
The PV module is fitted with a copper pipe which is specially designed with fins attached
with it
The coolant is supplied to the copper pipe via a DC pump which is connected to the sealed
reservoir.
A DC fan is used to cool the copper fins which are attached with the copper pipe.
The module temperature is monitored by a controller with the temperature sensor as
feedback to the unit The flow of coolant in the copper pipe is controlled by the controller
with respect to the temperature of the PV Module. The flow rate changes depend on the
temperature of the PV Module.
Through this invention the PV module temperature is maintained between 35°C to 40°C.
SHORT DESCRIPTION OF THE DRAWINGS
The invention described here is
Fig. 1: Shows a member (100) with a structural form of hybrid PV cooling Module.
DETAILED DESCRIPTION OF THE DRAWINGS
The following description describes the hybrid photovoltaic module (HPV). To the PV module (101) a copper base (103) and copper pipe is fixtured (104) firmly to copper fins (110) to eradicate the heat from the PV module. The entire PV module is firmly fixed to the PV base (102). The entire PV module temperature is controlled by the controller unit (107) via feedback from the temperature sensor (108). As the temperature increases in the PV module the controller switches between the coolant pump (106) and air blower (109) to reduce the temperature of the unit on the run. The coolant material (105) used here is a water-based coolant with mixture ratio of 50% water and 50% coolant liquid. The coolant reservoir is sealed to overcome tampering and the coolant is filled via coolant gate valve (111).
The entire system is controlled by the controller to keep the temperature of the PV module at nominal range.
