Innotech Achieves Higher PV Power Yields using Positive Sorting and Power Optimizers
By applying the principle of positive power sorting to its PV modules, the Scandinavian-German manufacturer Innotech Solar AS (ITS) is enabling its customers to generate higher energy yields than the nominal power rating. What’s more, even higher energy yields can be achieved in combination with a power optimizer or a micro-inverter particularly in non-optimal module string combinations, orientations and mounting applications.
â€œCombining ITS modules with power optimizers or micro-inverters allows them to increase this already high yield even further. Power optimizers and micro-inverters ensure that every single module works at its full capacity â€“ even if they have been connected unfavorably, such as in the event of the modules in a plant being fitted at varying angles of inclination or orientations, unequal shading or differences in output between individual modules. This enables our customers to exploit the advantage of our positively sorted modules even more,â€ according to Dr. Thomas Hillig, Vice President Module Sales & Marketing at Innotech Solar.
The Croatian installation company Solar Varibo recently completed a solar system on a challenging roof that points in three directions. Innotech Solarâ€™s positively sorted modules and the use of power optimizers are set to ensure that the PV project generates the best possible yields despite this disadvantageous roof shape. The 10 kWp plant has been mounted on a residential building in the Croatian town of Å½upanja.
â€œWe had initially feared that the complicated roof was not suitable for generating solar power. However, the high-performance ITS modules and the use of power optimizers more than make up for the disadvantages presented by the roofâ€™s shape and the plant will be capable of generating excellent yields,â€ reports Solar Variboâ€™s plant manufacturer Ivan Varzic.
A multitude of tests by independent experts, such as the Fraunhofer Institute, the Photovoltaik-Institut Berlin and PV Lab, have demonstrated the high performance, durability and positive environmental impact of Innotech Solarâ€™s European modules.
