PVPro Solar: Your Local Photovoltaic Specialist for Wennigsen am Deister

On-Site Planning Instead of a Standard Quote

We inspect your roof in Wennigsen on site: orientation, pitch, shading, structure and meter cabinet. We then size the system to your actual consumption and create a yield forecast you can base your decision on.

Brand Components We Know Well

We install modules from AIKO, JA Solar or Longi, Fronius inverters, BYD batteries on request and the K2 Systems mounting system. We get spare parts and manufacturer support for these components, which matters over the entire lifetime of your system.

Our Own Technicians and Grid Registration

Our own certified technicians handle installation and electrical work in line with VDE and TAB rules. We take care of registration with the grid operator (Avacon Netz) and in the Market Master Data Register for you.

PV, Battery, Wallbox and Heat Pump from a Single Source

Alongside the PV system, we install batteries, wallboxes and heat pumps and coordinate everything so that you use as much solar power yourself as possible. If you’re planning a heat pump later, we size the system for it now.

Fixed Price, 30/70 Payment and Service

You get a written fixed price and pay 30% on order and 70% only after installation. After commissioning, we remain your point of contact, with system monitoring and service even after the statutory warranty has expired.

Solar in Wennigsen: Key Facts at a Glance

Is Solar Energy Worthwhile in Wennigsen?

In the Hanover Region, we calculate about 893 kWh per kWp per year, so a 10 kWp system produces just under 9,000 kWh. The biggest benefit comes from self-consumption: every kilowatt-hour you use yourself replaces grid electricity, which is 37 cents at an assumed price of 37 ct/kWh. Power fed into the grid earns only about 7.70 ct/kWh. Without storage, households typically use 25 to 35% of their solar power themselves, and around 55 to 70% with storage.

Solar Energy in Wennigsen am Deister: What Matters Locally

• Slopes and forest: on the edge of the Deister, slopes and trees can cast shade in the morning or evening. We factor this into the yield forecast for your roof and tell you honestly if a system won’t pay off.
• East-west roofs: they generate more evenly across the day and often match a household’s consumption well.
• Listed buildings: around the monastery and in old village centres there are listed buildings. Here you usually need heritage approval for a PV system. We clarify this before the quote.
• Short distances: from Hanover we reach Wennigsen quickly, for the on-site visit and for installation.
