\r\nenergy by the help of photovoltaic greenhouse solar dryer under
\r\nforced mode. A single slope photovoltaic greenhouse solar dryer has
\r\nbeen proposed and thermal modelling has been developed. Various
\r\nparameters have been calculated by thermal modelling such as
\r\ngreenhouse room temperature, cell temperature, crop temperature and
\r\nair temperature at exit of greenhouse. Further cell efficiency, thermal
\r\nefficiency, and overall thermal efficiency have been calculated for a
\r\ntypical day of May and November. It was found that system can
\r\ngenerate equivalent thermal energy up to 7.65 kW and 6.66 kW per
\r\nday for clear day of May and November respectively.","references":"[1] Esper A and Muhlbauer W.
