Rare are the photovoltaic greenhouses that allow to grow normally, without having an illumination too handicapped by the existing structures. VGD helps to overcome this problem, and its photosynthetic lighting solutions allow to grow all year round fruits and vegetables to make the most of the material investment.
Initially, the photovoltaic greenhouses were propelled by the energy-consuming specialists on the part of the national market for the production of green power. The deal is simple, we provide you with a free production tools or low investment in return you occupy the land of your roof for a minimum 25 years. But over the past few years people have touted or exposed the agronomic capabilities of a private tool of more than 65% natural light intake.
Off to date the issue remains still topical in the face of the need to produce under these photovoltaic panels. Apart from a few marginal cultures, cultivating in this new environment does not remain an easy thing. The major problem is focused on the lack of light filtered by the design of the "green" greenhouse. This factor results in other disadvantages: the hygrometric Regulation (the cost of producing a PV greenhouse being pulled to its maximum because the options are scarce or then paid as in a standard glass glasshouse), lower temperatures off season (lack of natural heat), ethics (producers have a non-productive agricultural land area at the expense of conventional production and a shortage of land in the areas of implementation of this type of greenhouse).
VGD has one of the largest illuminated PV greenhouse area in Europe.
What for? Simply, the VGD system is the only one to make economically viable a production of strawberries, tomatoes, blueberries, raspberries, salads,… Thanks to the real-time control system of the crop lighting according to the natural intake, only the correct missing light necessary for a profitable production is delivered. Thus this solution allows to smooth all the disadvantages of a PV greenhouse with a minimum investment. The Delta of the acquisition cost of a standard glass greenhouse and the ability of the VGD system to consume 4 times less per square metre than the installed photovoltaic production allows agronomically profitable horticultural production.
