Greenhouses can be optimized with transparent solar panels capable of filtering wavelengths of light for solar energy production without affecting the growth and health of crops. What is a Transparent Solar Panel? A transparent solar panel converts sunlight into electricity using photovoltaic (PV) glass.
Scientists believe that transparent photovoltaic cells will have little effect on plant growth, making them ideal for use in greenhouses. They also present an opportunity to diversify technologies for producing sustainable energy. Greenhouses can become energy-neutral, producing energy equal to energy costs by blocking a limited amount of sunlight.
Get in touch! Traditional greenhouses rely on external fossil fuel derived energy sources to power lighting, heating and forced cooling. Specially designed BiPV solar glass modules for greenhouses, Heliene's Greenhouse Integrated PV (GiPV) modules offer a sustainable alternative with no additional racking or support required.
Solar greenhouses are currently the most energy-intensive agricultural sector. In literature, there is no worldwide mapping of solar greenhouse performance under different climate scenarios. This study analyzes the performance of a Venlo solar greenhouse for 48 localities around the world.
In addition to climate, which plays a crucial role, various parameters impact the solar greenhouse, including the type of crop (related to the specific need for plant growth), indoor lighting, the presence of soil, the evapotranspiration of the plants, the large size of the internal space, and the extensive transparent surfaces.
However, if farmers want to generate more energy, they can further reduce the amount of light transmitted. Transparent solar panels limit the use of primary energy sources (petroleum, natural gas) for heating and cooling the greenhouse, reducing greenhouses' energy footprint.
