There is an intense need to optimize agrivoltaic systems. This article describes the invention of a new testing system: the parametric open source cold-frame agrivoltaic system (POSCAS). POSCAS is an adapted gardening cold-frame used in cold climates as it acts as a small greenhouse for agricultural production. POSCAS is designed to test partially transparent solar photovoltaic (PV) modules targeting the agrivoltaic market. It can both function as a traditional cold frame, but it can also be automated to function as a full-service greenhouse. The integrated PV module roof can be used to power the controls or it can be attached to a microinverter to produce power. POSCAS can be placed in an experimental array for testing agricultural and power production. It can be easily adapted for any type of partially transparent PV module. An array of POSCAS systems allows for the testing of agrivoltaic impacts from the percent transparency of the modules by varying the thickness of a thin film PV material or the density of silicon-based cells, and various forms of optical enhancement, anti-reflection coatings and solar light spectral shifting materials in the back sheet. All agrivoltaic variables can be customized to identify ideal PV designs for a given agricultural crop.

The Western Innovation for Renewable Energy (WIRED) system is currently under construction to test out new open source methods to reduce PV systems costs and enable novel forms of agrivoltaics including the world's first agrivoltaic agrotunnel.

Services provided by agrivoltaics are: renewable electricity generation, decreased green-house gas emissions, reduced climate change, increased crop yield, plant protection from excess solar energy, plant protection from inclement weather such as hail, water conservation, agricultural employment, local food, improved health from pollution reduction increased revenue for farmers, a hedge against inflation, the potential to produce nitrogen fertilizer on farm, on farm production of renewable fuels such as anhydrous ammonia or hydrogen, and electricity for EV charging for on- or off-farm use.
