Balcony power crops present photo voltaic power and thus help to avoid wasting plenty of expensive vitality costs. And to make sure that a balcony power plant to supply as so much vitality as doable, it desires – in spite of everything – a great deal of photo voltaic. Nonetheless, if elements of the picture voltaic modules are throughout the shade, the vitality yield usually drops significantly. It must be completely totally different with the model new balcony power plant “selfPV balcony package deal deal 335 Wp Scorching-Spot Free” from Greenakku. As compared with typical strategies, the net retailer ensures significantly bigger vitality yields with partial shading of the picture voltaic modules. How is that doable?

Shadow causes blockage

The Greenakku balcony power plant makes use of a 335-watt picture voltaic module from AE Picture voltaic, which makes use of what’s referred to as hot-spot-free know-how, to generate electrical power. Which implies that each of the 60 picture voltaic cells is equipped with a bypass diode. They should ship a decisive profit, because of typical full-cell modules with out bypass diodes it actually works like this: If a photograph voltaic cell is throughout the shade and on account of this reality does not produce any electrical power, it blocks the current flow into of various cells by way of its line resistance, since they’re usually linked in assortment . This can outcome within the occasion of native scorching spots that hurt the module. To cease this, the entire row of cells usually switches off when a cell is shaded. The consequence: If even a slender shadow falls over a cell, it paralyzes the ability manufacturing of the corresponding row of cells.

27 % further power

Nonetheless, in picture voltaic modules with hot-spot-free know-how, the bypass diodes direct the current earlier the shaded cells and thus guarantee that every one totally different cells can proceed to supply current. In line with Greenakku, the utilization of bypass diodes ends in a significantly bigger current yield in partial shading – and this has even been confirmed. As an illustration, the Fraunhofer Coronary heart for Silicon Photovoltaics determined all through an inspection of the picture voltaic modules with hot-spot-free know-how that they solely lose three % of their complete output if a cell is shaded. Commonplace modules, then once more, lose 30 % of their effectivity if a cell is throughout the shade, in accordance with the consequence.

That’s what the Greenakku set gives

The “selfPV balcony package deal deal 335 Wp Scorching-Spot Free” balcony power plant set from Greenakku contains a Bosswerk mannequin inverter with an output power of 300 watts and a “Scorching-Spot Free” picture voltaic module from AE Picture voltaic with an output of 335 watts. A 5-meter connection cable and a mounting package deal are moreover part of the scope of provide. Counting on the mannequin, you could join the balcony power plant to balconies with sq. or spherical bars. Every the set for spherical balcony railings and the variant for sq. bars are at current obtainable at an introductory worth of spherical 587 in its place of 830 euros. Greenakku charges an additional 34 euros for forwarding.
