Filtration for Solar Panel Manufacturing & Cleaning
Updated: Feb 23, 2021
The burning of fossil fuels, such as coal and oil to produce electricity is one of the main contributors to global warming. With increasing awareness on the catastrophic affects of climate change, the world is shifting away from it's dependence on oil in search of greener alternatives.
Governments across the world have been taking initiatives to address this issue by encouraging the implementation of renewable energy (RE) through various national programs. Germany has targeted 65% of it's energy to come from renewable sources by 2030, while 50% of Denmark's power generation already comes from RE since 2019. Korea, a closer neighbour, is aiming for 35% by 2040. Back in Malaysia, the government has announced their target of achieving 20% by 2025.
Of the different RE alternatives, recent developments in solar photovoltaic (PV) systems have led to its phenomenal growth in Malaysia and across nations. Applications involving solar energy have also been gaining popularity in Malaysia due to favourable climate conditions of the country.
Choosing the right filtration system is paramount in the production of PV systems. During production, particulate contamination can cause defects on the crystal-clear panel surfaces and affect yield rates. Effective removal of contaminants not only protects these surfaces, but improves the efficiency of downstream processes, which cuts down on maintenance downtime.
Another issue with solar panels post production, is that they can get dirty very quickly. A dusty solar panel can reduce it's efficiency by 30-40% if not cleaned regularly. However, using unfiltered tap water to clean the panel surface is not enough as it may create hard water stains overtime.
