Personalisiertes Angebot Quickplan-Tool ABOUT US "As an engineer for renewable energies, I am convinced that anthropogenic climate change can only be stopped by converting our entire energy system to renewable energy sources. Photovoltaic systems in private as well as industrial format play an important role here. Moreover, no other technology can be implemented without additional sealing of surfaces. With their high levels of efficiency, long system lifetimes and moderate costs, they offer the ideal opportunity for everyone to actively participate in the energy transition. The technology is also financially feasible, like a bank investment with 3-6 % interest. Risks are basically non-existent and minimized through careful planning. As a competent specialist partner, we want to actively and individually support our fellow citizens - because climate protection is a community thing and begins with ourselves.

Die Geschichte Nach seinem Studium zum Ingenieur für Erneuerbare Energien gründete Stephan Gerhards die Firma Photovoltaik Gerhards mit dem Ziel, die Energiewende aktiv selbst mitzugestalten. 2020 noch als Ein-Mann-Betrieb mit Material-Lager in der eigenen Garage konnte Stephan Gerhards bei stetig wachsender Nachfrage nach Photovoltaik-Anlagen schon bald ein Team aus motivierten Werkstudenten aufbauen, die ihn bei der Installation unterstützten. Um alle Projekte von Planung bis Fertigstellung selbst durchführen zu können, hat Stephan Gerhards sein Qualifikationen fortwährend erweitert und so kann PVG alle Leistungen aus einer Hand anbieten. ​ Inzwischen ha t sich PVG am Markt etablieren können und ist im Metroloq Pulheim, einem Industrie-Komplex aus modernen Lager mit angrenzenden Büro und Besprechungsräumen zu finden. ​ Um der steigenden Nachfrage gerecht zu werden hat Rainer Herberg als Projektingenieur das Team erweitert und ist seit 2022 Ihr primärer Ansprechpartner für die Planung Ihrer Photovoltaik-Anlage und die Beratung für alles, was dazu gehört, zuständig .

9,49 kWp system in Cologne Overview In this system, we have installed a PV output of 9.49 kWp, as well as a 10.2 kWh battery storage and an intelligent wallbox. The system is divided into two strings and two MPPT. The modules parallel to the roof have a slope of 30 ° and an orientation to the northeast (299 °). The elevated modules have an inclination of 15 ° and an orientation to the southwest (208 °). All modules are combined with performance optimizers for the purpose of increasing yield, monitoring and security aspects. ​ The calculated energy yield is approx. 8,000 kWh per year, amortization is achieved after approx. 14 years. Components: - 365 Wp glass-glass modules from Bauer Energiesysteme GmbH - Tigo TS4-AO optimizers - Altec and K2 mounting systems Technology The power and data cables were run inconspicuously into the cellar via aluminum pipes and UV-resistant cable ducts. ​ This is where the house connection wall with the installed inverters and the storage unit is located. To accommodate all components, the meter cabinet was also completely refurbished and adapted to the current state of the art. ​ The wallbox is waiting for its first use in the garage. It is directly compatible with the other components and enables, among other things, intelligent charging with 100% own PV power.

Provisions for the provision of personal data We explain to you that the provision of personal data is in part required by law (e.g. tax regulations) or can also result from contractual regulations (e.g. information on the contractual partner). In order to conclude a contract, it may sometimes be necessary for a data subject to provide us with personal data that we subsequently have to process. For example, the data subject is obliged to provide us with personal data when our company concludes a contract with them. Failure to provide personal data would mean that the contract could not be concluded with the person concerned. Before the person concerned provides personal data, the person concerned must contact one of our employees. Our employee explains to the person concerned on a case-by-case basis whether the provision of the personal data is required by law or contract or is necessary for the conclusion of the contract, whether there is an obligation to provide the personal data and what consequences the failure to provide the personal data would have.

6,08 kWp system in Cologne Overview In this system, we have installed a PV power of 6.08 kWp and a home manager. All modules are interconnected in one line. With a slope of 36 ° and an orientation to the south (5 °), high energy yields of over 1,000 kWh / kWp are expected. All modules are combined with performance optimizers for the purpose of increasing yield, monitoring and security aspects. ​ The calculated energy yield is approx. 6,100 kWh per year, amortization will be achieved after approx. 16 years. Additional costs such as the meter cabinet, the scaffolding and other ancillary work are of course taken into account. In this way, the PV system also refinances any pending renovation of the house electrical system. Components: - 320 Wp glass-glass modules from Solarwatt - Tigo TS4-AO optimizers - Altec mounting system Technology The power and data cables were led under the roof cladding into the cellar via conduits and UV-resistant cable ducts. ​ The house connection wall with the installed inverter is located here. To accommodate all components and to comply with relevant standards and safety requirements, the customer's meter cabinet was also completely renovated and adapted to the current state of the art. ​ Other components attached to the wall are the DC surge protection and the box for controlling the Tigo optimizers.

3,65 kWp system in Cologne Overview In this system, we have installed a PV power of 3.65 kWp and an electricity meter. All modules are interconnected in one line. The roof-parallel modules have an inclination of approx. 30 ° and an orientation to the south-west (208 °). All modules are combined with performance optimizers for the purpose of increasing yield, monitoring and safety aspects - standard in a SolarEdge system anyway. ​ As you can see, there are already some objects and restricted areas on the roof that make the installation of the system difficult. However, thanks to technical sophistication, 10 modules could be placed. ​ The calculated energy yield is approx. 3,600 kWh per year, amortization is achieved after approx. 12 years. ​ Components: - 365 Wp glass-glass modules from Bauer Energiesysteme GmbH - SolarEdge P401 optimizer - Altec mounting system Technology The cables were run inconspicuously into the cellar via aluminum pipes and UV-resistant cable ducts. ​ The inverter was installed in the connection room near the meter cabinet. To accommodate all components, the interior of the meter cabinet was completely refurbished and adapted to the current state of the art. In most cases, however, a complete exchange of the cabinet is financially more attractive due to the reduced installation time. ​ Since the customer owns an e-car with a 1-phase charging station, it goes without saying that the correct phase assignment of the inverter and charging fuse was taken into account when wiring. Charging with solar power is possible in this way. ​ The box with DC surge protection (not visible) was also attached to the wall. Components: - SolarEdge 3680H including electricity - DC overvoltage protection TO REFERENCES

PV-Branche am Limit ​ ​ Liebe Interessenten, ​ leider hat die Vielzahl der aktuellen, weltweiten Krisen und Konflikte nun auch den Betrieb von PVG erreicht und zwingt uns zum Handeln. Wir folgen hiermit der Richtung, die unser Großhandel vorgibt und müssen Ihnen daher mitteilen, dass mit einer Umsetzung für Neukunden vor Mitte 2023 nicht zu rechnen ist. Dies ist dem immensen Materialmangel, den Lieferengpässen und Preisschwankungen geschuldet. ​ Leider können wir daher aktuell keine neuen Kunden aufnehmen. ​ Wir hoffen auf eine baldige Entspannung der Situation und freuen uns darauf, bald wieder wie gewohnt für Sie da zu sein. Bis dahin verbleiben wir mit ​ Sonnigen Grüßen, PVG Schließen
