The previous results shows that the energy supply of the resistance by the solar panels contributes to the increase
of the temperature before the grid. This increase grows proportionally to the number of the number of panels
associated in parallel it increases the electric current intensity and the increase of the temperature in the room
according to the produced joule effect. This increase has consequences on the dried products. With the use of one
single panel the difference in temperature ( air/product) at the beginning of the drying start quit high (7°C-10°C) this
difference reduces with time and remain steady up to the end of the drying (5°C - 6°C). This decrease is due to the
evaporation of an important quantity of water at the beginning of the drying, the product being still rich in humidity
