Concept and Technology

Together with experienced engineers and agronomists our PV
greenhouse was designed to:

  • maximise light transmittance
  • generate natural convection to improve climate control
  • minimise internal shadowing and maximise light reflection

The design characteristics have been developed and optimised in
partnership with the Politecnico di Milano University

serra-750x440

Proof of Concept: Agronomical Experimentation

In 2011 we developed a 500 sqm advanced testing facility in Apulia (Italy)
The experimentation has been conducted by the agronomists of one of the largest Italian greenhouse operators

serra-interno-1200x630

The results through multiple cycles
have proven that

the agronomical yield of the Gramma GH is the same of a non-PV greenhouse

Technical Specs of the Gramma PV greenhouse

  • Single sided, south facing canopy
  • PV panels covering c. 50% of the roof, no specific panel technology or brand requirement
  • Power density: c. 1,000kWp/Ha greenhouse built

Why does the Gramma GH work better than traditional PV greenhouses?

Light transmittance!

Gramma greenhouse: 90%
Other PV greenhouses: max 50%
