Solar module cooling tech based on waste neem oil

An international research team has placed a neem oil tank on the back of solar modules for cooling purposes. The proposed solution reportedly improves PV panel performance by up to 17. 8%. A group of scientists led by Kongu Engineering College in India investigated the use of waste neem oil as a cooling solution for PV modules. Neem oil is extracted from the seeds of the neem tree and is commonly used as a medicine for some skin diseases. The researchers explained that this oil acts like phase-changing materials (PCMs), which can absorb, store, and release large amounts of latent heat over defined ...
