SMA ShadeFix optimization is a proprietary, integrated inverter capability that optimizes the yield of PV systems in every situation – even in shading.
SMA ShadeFix optimization is a proprietary, integrated inverter capability that optimizes the yield of PV systems in every situation – even in shading.
PV Systems are generally installed in scenarios where they can convert the largest amount of sunlight into electric current. However, it is not always possible to prevent dormer windows, chimneys, trees and other obstructions from casting shadows on PV modules. This reduces energy yield and lengthens a system owner’s payback period.
This is why SMA has developed a superior optimization technique – SMA ShadeFix. And the best thing about this solution is that SMA ShadeFix optimization is integrated into SMA inverters at no extra cost.
Greater energy production
in most situations and over the entire lifetime of the system. Even in shading.
Enhanced safety
due to fewer components. This keeps the risk of failure to a minimum.
Improved quality & service life
thanks to field proven SMA products and automatic inverter monitoring.
Greater sustainability
through efficient complete solutions and high recyclability.
SMA ShadeFix is a software solution integrated into the inverter that comprehensively optimizes energy yield in PV systems and in most cases is more effective than module optimization hardware solutions. This has been proven by a scientific study entitled “The Impact of Optimizers for PV Modules” carried out by the University of Southern Denmark in May 2019.
No shading
The ideal PV system is not shaded and achieves maximum energy production with SMA ShadeFix optimization. Why? Lower conversion losses and electricity demand of the module optimizers.
Light shading
In slight shading due to a chimney, for example, systems with SMA ShadeFix optimization achieve greater energy production than those with traditional module optimizers. Why? The unnecessary electricity demand of the module optimizers.
Moderate shading
In the case of heavier shading due to trees, for example, systems with SMA ShadeFix optimization achieve greater energy production. Why? The unnecessary electricity demand of the module optimizers.
Heavy shading
Only in heavy shading do traditional module optimizers achieve some benefit. A system design with selective deployment of module optimizers can be useful here.
Why do we use integrated solutions at SMA? Because as the number of components in the entire system increases, so does the failure rate of the PV system. This is why you should never install more devices than necessary.
The benefits are clear:
There are, of course, many reasons to an efficient system design: effective material use, low transportation costs, fewer service calls required – these are only a few examples. As an innovative company, we are always thinking one step ahead in order to combine long-term business success with environmental protection and social responsibility.
The proprietary inverter software SMA ShadeFix increases energy yields of PV systems, even if the modules are in shade, without the need for additional hardware. And it is backed by a study conducted by the University of Southern Denmark.
