Turnkey solar PV for businesses
From the 15-minute load profile to service throughout operation. Solar PV, battery, transformer station and grid connection with one partner.
- 1A plant sized to consumptionRoof, land or carport. Capacity from 15-minute data, not annual consumption.
- 2Switchboard and meteringIn-house switchboard production, design in EPLAN, metering and protection.
- 3Grid connectionReserved capacity, conditions of ZSD, SSD, VSD and a transformer station if needed.
What matters is not annual consumption but when you consume
A commercial PV plant earns money when its output coincides with consumption. That is why we design it from the 15-minute load profile, which we request from the distribution system operator on your behalf, and not from the annual consumption on your invoice.
The same data shows how much you pay for reserved capacity and when your demand peaks occur. That is often a bigger cost than the energy itself, and it is solved by a controlled battery, not more panels. We cover the whole project, including the transformer station, MV connection and service, with one partner.

How we work together
- 01
Assessment from your invoice and data
Send your invoice and 15-minute data. Within three working days you have capacity, battery, economics and subsidies.
- 02
Site visit and design
Structural check, cable routes, space for the switchboard and battery. Design and connection application.
- 03
Permits and contracts
Notification or permit, connection agreement, subsidy application with our documents.
- 04
Construction
Our own installation crews, electricians and inspection technicians. We are responsible for the deadline.
- 05
Commissioning and service
Connection, electrical inspection, documentation, monitoring centre monitoring, service contract.
- 34MWp
- installed capacity
- 495+
- completed projects
- 5to 9 weeks
- usually from signing to commissioning
Free technical and economic assessment
From your invoice and 15-minute data we calculate PV capacity, battery size, reserved capacity, economics and subsidy eligibility. You have the result within three working days.
What decides the economics of a company PV plant
Capacity follows the load profile, not the roof area
From 15-minute data we see how much of the output is actually consumed. A larger plant without a battery often means only more surplus sold at the feed-in price.
A battery sized for a subsidy is not a battery sized for economics
Calls set a kWh-to-kW ratio. If you want peak shaving and spot-price control, we size a second battery from your data, not from the call.
We treat grid connection as part of the delivery
Connection conditions, the MV connection and the transformer station decide the timeline more than installation does. That is why we handle them from day one, with our own people.
Current calls for businesses and their conditions are on the page Subsidies. Battery storage and control by spot prices are on the page Battery storage.
Why do it with us
495+ projects, 34 MWp installed capacity
From 30 kWp on a workshop roof to more than 1 MWp for industry.
Our own team for the whole project
Design, engineering, installation, switchboards, inspections and dispatch are all employees.
MV expertise
We build and manage transformer stations and MV connections; a larger plant cannot happen without them.
Certified partner of manufacturers
Huawei, GoodWe, Solinteg, Sungrow, LONGi, Qcells. ISO 9001, 14001 and 45001.
One project, six services
It is rarely just one thing. On a single delivery we also handle what sits upstream and downstream in the circuit.
Questions we get asked
1How much does solar PV for a business cost?
The price per kWp falls with plant size and depends on the roof, technology, connection and whether a battery or transformer station is included. We do not quote without a site visit and consumption data; within three working days of receiving your invoice and interval data you get a technical and economic assessment with an indicative budget.
2What is the payback?
With a suitable design and high self-consumption, typically a single-digit number of years; the exact figure depends on your load profile, electricity price and subsidy. The assessment uses your 15-minute data, not an average.
3How much roof do I need?
Roughly 5 to 7 m² per 1 kWp on a flat roof with row spacing. For 500 kWp that is about 3,000 m². The roof's load capacity is verified by a structural engineer, whom we arrange.
4Do I need a building permit?
It depends on capacity and on whether it is a roof or land. Permits, notifications and negotiation with the distribution system operator are part of the delivery; our engineering team handles them.
5Who looks after the plant after commissioning?
Our monitoring centre, which monitors more than 300 systems around the clock. The service contract covers inspections, cleaning, electrical testing on schedule and faults within the agreed time.
6Can solar PV be combined with a subsidy?
Yes; current calls for businesses and their conditions are on the Subsidies page. We promise the process, not the outcome: we prepare the documents and size the battery according to the call conditions.
Non-binding enquiry
State your annual consumption or monthly bill, type of operation and whether you have your own transformer station. We will get back to you by the next working day.
