Switch to clean electricity - with us

Photovoltaic sys­tems ge­ne­ra­te clean elec­tri­ci­ty and thus help to re­du­ce CO2 emis­sions. Energy pri­ces are con­stant­ly ri­sing. Solar en­er­gy re­mains free. And si­lent. Benefit from the long-​term and en­vi­ron­men­tal­ly fri­end­ly way of ge­ne­ra­ting elec­tri­ci­ty! Rising elec­tri­ci­ty pri­ces and the state of our pla­net make it necess­a­ry, fal­ling sys­tem pri­ces make it pos­si­ble... and we help you with the plan­ning and en­su­re pro­fes­si­o­nal implementation.

How it works

A pho­to­vol­taic sys­tem es­sen­ti­al­ly con­sists of a solar ge­ne­ra­tor, an in­ver­ter and a meter. Several pho­to­vol­taic mo­du­les are con­nec­ted toge­ther in the solar ge­ne­ra­tor, which in turn con­sist of many solar cells. Direct cur­rent is ge­ne­ra­ted in the solar cells by solar ra­di­a­ti­on. In grid-​connected sys­tems, this is con­ver­ted into al­ter­na­ting cur­rent via the in­ver­ter, which can then be con­su­med by the user or fed into the pu­blic grid.

Feed in or use it yourself?

A few years ago, the high feed-​in ta­riff made it ex­tre­me­ly worthwhile to fully feed self-​produced elec­tri­ci­ty into the grid. However, the feed-​in ta­riff is fal­ling, while elec­tri­ci­ty pri­ces con­ti­nue to rise. A sys­tem for full feed-​in is now less worthwhile, whe­re­as self-​consumption of solar power is be­co­ming in­crea­sing­ly at­trac­ti­ve. This is be­cau­se pho­to­vol­taic sys­tems sup­ply you with much che­a­per elec­tri­ci­ty than your grid ope­ra­tor. The trend is the­re­fo­re cle­ar­ly to­wards in­creased elec­tri­ci­ty use in order to get the most out of ma­xi­mum self-​consumption.

Maintenance and cleaning of photovoltaic systems

Photovoltaic mo­du­les usu­al­ly have a ser­vice life of up to 25 years. Progress en­su­res that the ser­vice life of mo­du­les con­ti­nu­es to in­crease. Some ma­nu­fac­tu­rers even offer vol­un­ta­ry pro­duct and per­for­mance gu­a­ran­tees of 25 years. For many ma­nu­fac­tu­rers, howe­ver, the gu­a­ran­tee pe­ri­ods are bet­ween five and 15 years. Important: Not all com­pon­ents last the same length of time. An in­ver­ter usu­al­ly only lasts around 15 years and must be re­placed du­ring the ser­vice life of the PV system.

Lightning protection for photovoltaic systems

PV sys­tems do not in­crease the risk of a light­ning strike or the risk of fire. However, a PV sys­tem has a di­rect con­nec­tion to the house's elec­tri­cal in­stal­la­ti­on, so di­rect light­ning strikes or in­di­rect light­ning ef­fects can have con­se­quen­ces. Not only can the roof sys­tem or the elec­tri­cal in­stal­la­ti­on be da­ma­ged, but in the case of a grid-​connected PV sys­tem, a light­ning strike may even cause a far-​reaching power failu­re. When it comes to light­ning pro­tec­tion, a di­s­tinc­tion is made bet­ween the ex­ter­nal light­ning pro­tec­tion sys­tem and in­ter­nal light­ning protection.
