About Which type of photovoltaic panel water channel is better to use
In this experiment, six PV modules with 185-W peak output each and 120 water nozzles are placed over the PV panels. The authors seek to minimize the amount of water and energy used to cool the PV modules. They set the maximum allowable temperature of modules as 45 °C, and the temperature reduces up to 10 °C.

The literature shows various types of passive cooling mechanisms based on the application of solar PV panels. Immersion cooling, heat pipes, natural air cooling with fins, heat sinks, and improved heat exchanger designs were found to yield uniform temperature in most of the PV installations.
Cooling the PV panel from its maximum cell temperature to 39.82 °C with 5 m/s air velocity and 82 fins cooling channel is achieved and new PV panel efficiency is recorded as 18.92 %. Environmentally considerations show that the use of solar energy provides the reduction of coal and natural gas-based CO 2 emissions as 15 and 8 tons, respectively.
The idea is simple: install solar panels over canals in sunny, water-scarce regions where they reduce evaporation and make electricity. A study by the University of California, Merced gives a boost to the idea, estimating that 63 billion gallons of water could be saved by covering California’s 4,000 miles of canals.

6 FAQs about [Which type of photovoltaic panel water channel is better to use]
What is liquid cooling of photovoltaic panels?
Liquid cooling of photovoltaic panels is a very efficient method and achieves satisfactory results. Regardless of the cooling system size or the water temperature, this method of cooling always improves the electrical efficiency of PV modules. The operating principle of this cooling type is based on water use.
Can solar panels save water?
The idea is simple: install solar panels over canals in sunny, water-scarce regions where they reduce evaporation and make electricity. A study by the University of California, Merced gives a boost to the idea, estimating that 63 billion gallons of water could be saved by covering California’s 4,000 miles of canals.
Does hydraulic cooling improve the optical efficiency of PV panels?
Bhakre et al. reviewed a performance evaluation of PV panel surfaces under hydraulic cooling. They found that continuous water flow over the top surface significantly cools the PV panel and cleans its surface. Hence, the optical efficiency of the PV panel is increased.
Should solar panels be placed over water bodies?
Placing solar PV panels over water bodies (using, for example, floating panels or water-body-spanning infrastructure) conserves water by reducing evaporation losses through effects on incident solar radiation and surface wind speeds 7, 8, 9, 10, 11, 12, 13.
Does a floating PV system increase electrical efficiency?
Increase in cooling efficiency 2.75 - 57.25%, Dörenkämper et al. presented experimental and simulation results in PVsyst software for a floating PV system. In this case, the electrical efficiency of the PV is enhanced by the cooling effect of the water on which the PV system floats.
Do rooftop integrated photovoltaics have a passive air cooling channel?
A model and heat transfer correlation for rooftop integrated photovoltaics with a passive air cooling channel. Sol Energy 2009, 83, 8, 1150-1160.
