6 FAQs about [V-shaped water channel for photovoltaic panels]

What are the different types of PV panel cooling technologies?

Current PV panel cooling technologies can be divided into two categories: active cooling and passive cooling 12, 13, 14. Active cooling uses a coolant such as water or air to dissipate heat from the surface of a PV panel 15, 16, 17.

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.

How does water cooling of PV panels work?

Water cooling of PV panels is also studied by Irwan et al. where the performance of PV panels was compared with panels cooled by water flow on the front surface. The study was conducted under laboratory conditions. Water was sprayed on the front face of the panels. A water pump was responsible for spraying water in the cooling system.

What is a photovoltaic (PV) system?

A photovoltaic (PV) system converts solar energy into usable electricity and is currently the most popular means of solar energy use 1, 2. In 2019, the total installed capacity of solar PV panels worldwide reached 600 GW and it is projected that the global PV capacity will reach 1,500 GW by 2025 and 3,000 GW by 2030 (ref. 3).

Why do PV panels need a cooling system?

1. PV panels cooling systems Cooling of PV panels is used to reduce the negative impact of the decrease in power output of PV panels as their operating temperature increases. Developing a suitable cooling system compensates for the decrease in power output and increases operational reliability.

How does a solar PV system work?

The recycled water is collected in a U-shaped borehole heat exchanger (UBHE), installed in an existing well to enhance the cooling capacity. The water exchanges heat with shallow-geothermal energy. Finally, the panel is again sprayed with water to cool it. The water in this cooling system first cooled the PV panel.
