The Greenhouse Agrivoltaic Advantage

  • Moving electrical source close to the user thus reducing power transport costs. 

  • Optimizing crop's yeilds and water consumption by shading

  • Globally dispersed market with weighting towards richer countries

  • Enable partial and responsive coverage to avoiding damage to crops in winter

  • Ensures that crops receive exactly the amount light they need

  • Light and low cost construction for the tracking system avoiding potential damage from high winds

  • Giving the cultivar's unique optimized growth conditions will increases the yield and quality of crops . 

  • Year-round crop responsive tracking system

  • Pre-programmed system for a variety of cultivars, each heaving a specific optimum growth condition, significantly increases the yields.

  • PV can replace shading nets or shading screens

  • Tracking keeps the highest outputs as solar incidence angle is always normal to the panel

  • A lightweight, plug and play responsive PV tracking system inside the greenhouse

  • Combining power generation with optimum crop yield

  • Provides plants with the optimum light and temperature

  • Power loss from effect of polyethylene greenhouse coverings is offset by a simple tracking system that allows just the right amount of light to reach the plants

  • ​Summary

  • Our system offers a way to maximize yield of electric power and crops

  • This is a simple system, easy to install and easy to maintain

  • With solar power now offering the lowest LCOE and growing power needs the world needs to use agricultural land for solar energy

  • We offer a path towards combining food and energy security in a package that is harder to copy

  • We have completed two pilot studies which demonstrated that the system is functioning as anticipated 

  • Many greenhouses have electrical infrastructure / near power mains thus reducing power transport costs

  • Modern greenhouses are intensive users of electricity

  • Many crops need shading for optimum harvests 

  • Globally dispersed market with weighting towards richer countries

Problems with current
agrivoltaics solutions

  • Coverage must be limited to avoid damage to crops in winter

  • No way to ensure that crops receive exactly the amount light they need

  • Highly robust and expensive construction needed to avoid damage from high winds

Advantages 

Different crops need different growth conditions

(by optimizing growth conditions, the yield will be increased accordingly)

DLI  is a cumulative index of daily light in the greenhouse based on measurements of photons/m2

  • Year-round crop responsive tracking system

  • Pre-programmed system for a variety of crops, each heaving a specific optimum growth condition, significantly increases the yiels

  • DLI  is a cumulative index of daily light in the greenhouse based on measurements of photons/m2

  • PV can replace shading nets or shading screens

  • In winter crops would need more light

  • Highest outputs when solar incidence angle normal to the panel

  • A lightweight, plug and play responsive PV tracking system inside the greenhouse

  • Combining power generation with optimum crop yield

  • Provides plants with the optimum light and temperature

  • Power loss from effect of polyethylene greenhouse coverings is offset by a simple tracking system that allows just the right amount of light to reach the plants

​Summary

  1. Our system offers a way to maximize yield of electric power and crops

  2. This is a simple system, easy to install and easy to maintain

  3. With solar power now offering the lowest LCOE and growing power needs the world needs to use agricultural land for solar energy

  4. We offer a path towards combining food and energy security in a package that is harder to copy

  5. We have completed two pilot studies which demonstrated that the system is functioning as anticipated 

Different crops need different growth conditions, as shown here by the average daily light integral values of different crops. And these needs change depending on the growth stage of the plants.

For agrivoltaic solutions, low DLI requirements result in more electric power than high DLI, since a larger cover of PV would result in more shade.

If we can control and optimize DLI: Prolong growing seasons in GHs and increase yields, new era for agriculture.
