Solar and EV charging for apartment buildingsWith one contact person.

Whoever manages a property is responsible to owners and tenants. A solar system has to pay off, the meeting has to agree, and residents ask about EV chargers. And in the end the billing stays with property management.

We know this situation. That is why we plan more than technology. We also prepare what you need to decide and to keep day-to-day running simple. We start with a free site visit, and the binding quote follows within 72 hours.

What concerns property managers

The meeting: In condominium ownership, a system on the common roof usually needs a resolution. Owners want to see figures: costs, yield, subsidies and the split between the parties.

The tenants: They want cheap electricity and a car that can charge at its own parking space. At the same time, nobody should be forced to take part.

The effort: Metering, contracts and billing must not become a permanent building site. This is the most common worry, and it is justified.

One contact person for everything

With us, you have one contact person from the first conversation to commissioning. They coordinate planning, notification to the commune and grid operator, metering, installation and acceptance. Our own installers work on site, so there are no interfaces between companies.

Sharing solar power: ZEV, vZEV and LEG

With a self-consumption community (ZEV), the parties in the building share the solar power from their own roof. The internal tariff is below the grid tariff, and a larger share of the power stays in the building. This improves the profitability of the system.

There are three models:

• ZEV: all parties are connected through one shared grid connection.
• vZEV: each party keeps its own connection, and the grid operator allocates the solar power on paper.
• LEG: the local electricity community has been possible since 1 January 2026 and also links neighbouring buildings.

Which model fits depends on the building, the grid connection and the grid operator. We clarify this at the site visit. We will also tell you openly if a ZEV is not worthwhile for your building.

EV charging in the underground car park

Electric cars are coming to apartment buildings too. The problem: many cars hang on the same building connection. Load management shares the available power between the cars that are charging and prevents overload. This often avoids an expensive upgrade of the building connection.

We recommend building the basic installation for all parking spaces right at the start. Wallboxes are added later as needed, without opening the cable routes again. More under EV charging in underground car parks.

Billing without paperwork

Whoever charges or uses solar power pays for their own consumption. We plan the metering so that the data arrives digitally and feeds into billing. Property management decides whether to bill itself or to hire a service provider. As a smart-me Partner 2025, we rely on meters and software that deliver data without manual effort.

Informing the residents

Tenants and owners want to know what is coming. We supply texts for a letter or a notice: when work takes place, where the access routes are, when the power is briefly switched off. On the topic of solar power in the building, we also answer residents’ questions if property management wishes. Taking part in a ZEV is voluntary, and solar power must not cost more than grid power. We explain this in plain words.

Existing properties

Most of the buildings you manage are already built. On a walk-through we look at the roof, meter locations, risers, distribution boards and the underground car park. In refurbishments, it pays to renew meter locations and cable routes at the same time, so that the flats are ready for metering and billing. The result is a concept you can put before the owners.

Documents for the meeting

So that the meeting can decide, we supply:

• the binding quote with yield and subsidies
• a profitability calculation for the building
• the split of costs and income
• the schedule up to commissioning
• contract templates that you check with your legal adviser

This does not replace a legal review. If you do not have a system yet, everything starts with the solar system.
