Experiment and modelling of photovoltaic modules under solar flux augmented by planar reflectors in a Paris suburb climate

Résumé

Photovoltaic modules are generally installed by the application of empirical rules based on the principal goal of avoiding shadows during most of the periods of high solar irradiation and secondly of limiting the loss of diffuse solar irradiation. An installation on a horizontal surface results in widely-spaced rows of modules with a relatively low tilt angle. The addition of inter-row reflectors augments the direct and diffuse flux reaching the cells while resulting in a lower inter-row spacing and a higher tilt angle. The PV production process is a result of a combination of many physical processes that must be coupled in a model to accurately forecast the production of a given system in a given area. The “Aleph” project aims to define clear rules for optimal settings of systems of PV rows with fixed inter-rows reflectors in a specified location and climate. Two PV technologies are considered: amorphous silicon (a-Si) and polycrystalline silicon (p-Si). Optimization could result in maximizing the yearly or winter production, or the produced energy per unit of PV or roof surface. Any other techno-economic factor can be optimized, such as financial payback or energy payback. This work combines experiments on module behaviour in an outdoor environment on the SIRTA meteorology platform and an “infinite row model” (IRM) based on Cartesian optics and analytical solutions. It includes angle-dependent reflection, absorption and transmission, calculation of the effective irradiation and temperature- and irradiance-dependent cell efficiency. The experiment shows 5 to 35% gain in daily electricity production, and was confirmed by the model.
