Documentation and inspection reports in accordance with DIN EN 62446 standards<\/li>\n<\/ul>\nWhether you require a one-time system assessment or scheduled maintenance at regular intervals, we tailor our services to your specific needs. For commercial installations, we also take into account insurer requirements and recurring inspections in accordance with DGUV Regulation 3.<\/p>\n
Hassle-Free Warranty Management<\/h3>\n
The true quality of an installer becomes evident when a warranty claim arises. We exclusively install components from manufacturers we trust: AIKO, JA Solar, and Longi modules; Solplanet inverters; EcoFlow battery storage systems; and K2 mounting systems. These manufacturers offer product warranties ranging from 10 to 25 years and performance warranties of up to 30 years on solar modules.<\/p>\n
If a component does fail, you do not have to navigate support hotlines and paperwork yourself.<\/p>\n
Manufacturer Communication<\/h4>\n
We handle all communication with the manufacturer. Fault reports, log files, and serial numbers are prepared in the format required by the manufacturer, significantly accelerating warranty claim approval.<\/p>\n
Complete Documentation on File<\/h4>\n
As your installation partner, we maintain full documentation of your system, including commissioning reports, component lists, and technical datasheets.<\/p>\n
End-to-End Warranty Processing<\/h4>\n
From submitting the warranty claim and coordinating replacement deliveries to professionally installing the replacement component, we manage the entire process for you.<\/p>\n
Expansion Consulting for Existing PV Systems<\/h3>\n
Has your electricity demand increased due to an electric vehicle, heat pump, or changing household needs? Many PV systems can be expanded cost-effectively and efficiently. We assess both the technical feasibility and economic viability of potential upgrades.<\/p>\n
Battery Storage Retrofit<\/h4>\n
Depending on your existing setup, battery storage can be integrated either on the DC side through a hybrid inverter or as an AC-coupled solution, such as those offered by EcoFlow. We size the battery according to your actual consumption patterns. Good to know: retrofitted battery systems also qualify for the current 0% VAT rate under Section 12(3) of the German VAT Act (UStG).<\/p>\n
Wallbox Integration<\/h4>\n
With PV surplus charging, your electric vehicle charges primarily when solar energy is available. We coordinate the wallbox, inverter, and energy management system and handle registration as a controllable consumption device under Section 14a of the German Energy Industry Act (EnWG).<\/p>\n
Additional Solar Modules<\/h4>\n
If roof space and inverter capacity allow, we evaluate the potential for adding more modules and manage all required registrations with the grid operator and the Market Master Data Register.<\/p>\n
Future-Proof Planning<\/h4>\n
Whether you are considering a heat pump, dynamic electricity tariffs, backup power capability, or future energy requirements, we ensure your system remains suitable for years to come.<\/p>\n
See our project references from Hanover and the surrounding region to learn how these upgrades are implemented in practice.<\/p>\n
Our Service Guarantee<\/h2>\n
For us, statutory warranty obligations are the minimum standard, not the benchmark. As a regional photovoltaic specialist company, we stand behind our work long after your system has been commissioned.<\/p>\n
