Research ArticleOpen accessIn the abstractDesign and Development of a Photovoltaic Power System for Tropical Greenhouse CoolingFaisal Mohammed Seif Al-Shamiry, Desa Ahmad, Abdul Rashid Mohamed Sharif et al.Renewable energy sources like photovoltaic (PV) panels are used today in many applications. Natural ventilation in tropical greenhouse is common method for ventilation, which gives higher inside temperatures compared to the outside temperatures. In addition, this type of ventilation is not enough to reduce high temperature inside the structure in low land areas. Thus the requirement of cooling is increased. … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 8,216 accessesView PDFCite
