Photovoltaic solar energy is obtained by converting sunlight into electricity using a technology based on the photoelectric effect. It is a type of renewable, inexhaustible and non-polluting energy that can be produced in installations ranging from small generators for self-consumption to large photovoltaic plants.
However, manufacturing these Solar Panels is a Cost Intensive process, which utilizes huge amounts of Energy as well.
It all starts with the raw material, which in our case is sand. Most solar panels are made of silicon, which is the main component in natural beach sand. Silicon is abundantly available, making it the second most available element on Earth. However, converting sand into high grade silicon comes at a high cost and is an energy intensive process. High-purity silicon is produced from quartz sand in an arc furnace at very high temperatures.
Quartz sand is reduced with carbon in an electric arc furnace at temperatures > 1900°C to metallurgical grade silicon.
Therefore, strictly speaking, cooling requirement is highly needed in this industry. In addition to effective cooling, water quality is also important since the impurity will normally cause blockage in the cooling pipe.
In long-term view, the stability of closed circuit cooling tower is much higher than plate heat exchanger. Therefore, SPL also suggest that Hybrid Cooler totally replace the open cooling tower with heat exchanger.
The biggest different characteristics between SPL Hybrid Cooler and closed circuit cooling tower and other cooling tower is: Utilizing internal heat exchanger of cooling tower separate cooling water for equipment (for inner water) and cooling water for cooling tower (outer water) to ensure that cooling water is always clean for casting or heating equipment. In that case, it’s only necessary to clean one cooling tower instead of all cooling water pipes and equipment.
