What does a photovoltaic system cost?

That depends on the roof area, the covering, the number of modules and the state of the meter position. So we quote no flat price and instead work out a written quotation after the site visit.

How much electricity will my roof produce?

Orientation, pitch, shading and the area that can actually be covered decide that. We look at the roof and tell you what can be planned. A figure given beforehand would be a guess rather than a calculation.

Do you handle the registration?

Yes. The papers for the grid operator and for the German market data register belong to the scope of work and are not left with you.

Can a battery be added later?

Often it can. Whether it works depends on the inverter and on the space beside the meter position. Say so at the site visit and we plan the system that way from the start.

Does a wallbox fit with it?

A charging point and a photovoltaic system sit on the same meter position. If both are coming, we plan them together rather than opening the cabinet a second time later.

Who comes out if the system faults?

The same firm that built it. Call or write, and we look at what the inverter is reporting and come out.

Schedule of services

What actually gets done on a roof like yours

A photovoltaic system is roof work and electrical work at the same time. This list is the scope we take on for a house in Gangelt.

No.	Service	Scope
01	Advice and survey	Roof, orientation, shading and the meter position are inspected on site.
02	Module layout	The array layout, the cable routes and the place for the inverter are settled.
03	Mounting system	Roof hooks and rails are set to suit the covering that is already there.
04	Module fitting	Modules are placed, aligned and wired into strings.
05	Inverter	Position, connection and configuration in the plant room or at the meter.
06	Meter cabinet and connection	Meter cabinet, protective devices, equipotential bonding and surge protection.
07	Registration	The papers for the grid operator and the German market data register are prepared.
08	Commissioning	Testing, a measurement record, instruction and handover of the documents.
09	Storage and charging point	A battery and a wallbox can be planned in now or added later.
10	Servicing and faults	Visual inspection, measurement and fault attendance on the existing system.

You know what you need, or you do not know yet. Both are a good moment to ask.

Legend

The parts a system is made of

Six assemblies, and that is all. Once you know them you can read any quotation, including somebody else’s.

Modules
Frame, glass and junction box. They lie across the roof and produce direct current.
Mounting system
Roof hooks, rails and clamps, matched to the covering of that particular roof.
Inverter
Turns the direct current from the modules into the alternating current of the house.
Meter position
Cabinet, protective devices and supply cable. This is where the system meets the grid.
Battery storage
Takes up what the house does not need at that moment. Optional, never compulsory.
Charging point
A wallbox sits on the same meter position, so it is considered from the start.

Process

From the enquiry to the handover

Five steps, in this order. After each of them you know where you stand.

Enquiry
By form or by telephone. Give us the address, the roof shape and what you have in mind.
Site visit
We look at the roof, the covering, the cable routes and the meter position, and measure.
Quotation
In writing, with the scope, the components and a window for the work.
Installation
Mounting system, modules, inverter and the connection at the meter cabinet.
Handover
Commissioning, registration, instruction and the documents for your records.

Step one: a few lines from you.
