Solar Panel Installation in Hanover: How PVPro Solar Does It<\/h2>\n

With us, installation isn’t a single appointment but a fixed process from one source: preparation, roof installation by our own fitters, electrical installation by certified electrical specialists from our team, registration and commissioning. Installation is included in the fixed price of your quote, with no separate bill afterwards.<\/p>\n

1. On-Site Visit and Preparation<\/h3>\n

Before the first tradesperson sets foot on your roof, there’s the on-site visit: we check the roof area, orientation, structure and your existing meter cabinet. For terraced and semi-detached houses, we plan the required fire separation distances<\/a> from the start. At the same time, we clarify registration with your grid operator, which in Hanover is usually enercity Netz and in parts of the region Avacon. Only then do you receive a written fixed-price quote, and we agree the installation date with you.<\/p>\n

2. Scaffolding and Roof Safety<\/h3>\n

Nobody goes onto the roof until fall protection is in place. Depending on the roof shape and access, we put up fa\u00e7ade scaffolding or secure individual work positions, always in line with the legal requirements for fall protection.<\/p>\n

3. Mounting System<\/h3>\n

The K2 Systems substructure is fixed to suit the roof. The spacing of the fixing points depends on the roof pitch, rafter spacing and the snow and wind load zone at your location, so the system stays secure even in storms.<\/p>\n

4. Modules<\/h3>\n

AIKO, JA Solar or Longi modules, depending on the quote, are clamped onto the mounting system. A ventilation gap is deliberately left between the modules and the roof so they don’t overheat and keep their yield.<\/p>\n

5. DC Cabling<\/h3>\n

The modules are connected with DC cables, which are run to the inverter in weather-protected, UV-resistant cable ducts.<\/p>\n

6. Inverter, Battery and Grid Connection<\/h3>\n

The Fronius inverter is mounted and connected to your home’s electrical system, and a BYD battery, if included in the quote, is integrated at the same time. This step usually requires a short interruption of your power supply, typically two to four hours, and we let you know in advance. Under the Solar Peak Act, new systems without a smart metering system may feed in at most 60% of their module output. We set this in the inverter.<\/p>\n

7. Registration and Commissioning<\/h3>\n

After installation, we register your system with your grid operator and in the Market Master Data Register. At commissioning, the electrical specialist carries out a functional test: measuring the voltages of the individual module strings, checking all protective devices and verifying that the inverter delivers plausible yield data. We then set up the monitoring app so you can track your yields from day one.<\/p>\n

Safety and Standards for Solar Panel Installation in Hanover<\/h2>\n

The installation follows the relevant VDE standards, in particular VDE-AR-N 4105 for the grid connection, and your grid operator’s technical connection requirements (TAB). With us, the electrical installation is carried out exclusively by certified electrical specialists, not by the roof fitters alone. That’s not a formality: without this sign-off, you get neither MaStR registration nor approval from the grid operator.<\/p>\n
