“…In recent years, many researchers have studied the use of photovoltaic panels to provide electricity for the air conditioning of the greenhouse (AlIbrahim et al, 2006;Rocamora and Tripanagno stopoulos, 2006;AlShamiry et al, 2007;Campiotti et al, 2008;Sonneveld et al, 2008;Nayak and Tiwari, 2009;Yano et al, 2009;Ganguly et al, 2010;Sonneveld et al, 2010aSonneveld et al, , 2010bYano et al, 2010;Sonneveld et al, 2011;Lopez-Marin et al, 2012;Kadowaki et al, 2012). The results obtained are often favourable to the production of energy from photovoltaic elements but the shade created by them inside the structure appears to be excessive for a normal development of agriculture.…”
