For solar companies and installers
Do not sell less PV. Sell a more complete system.
The old PV calculation is changing. With storage, your own electricity tariff and pooling, the business case can work again. A partner offering for solar professionals.

The old PV calculation is changing.
Your quotation used to add up through self-consumption and feed-in. That era is ending. From 2027, remuneration is expected to follow the hourly spot-market price. Above 150 kW, there may be no minimum remuneration. At midday, electricity can have a negative price. Customers increasingly ask where the surplus electricity will go, and a clear answer can win the order. The solar obligation creates projects, but clients may hesitate if the roof installation alone no longer adds up. Installation prices are competitive, modules are increasingly interchangeable and margins are shrinking. To sell PV in the future, you will need to offer storage, tariffs and energy-market services as well.
Sell the system, not just the roof.
You keep the customer, while we provide the system architecture, profitability calculation and technical basis for approval in accordance with SVGW H10001. For small roofs, you can use batteries from your own range. For larger roofs, commercial premises, developments and farms, long-duration storage can provide electricity, heat and flexibility from one system. Two additional building blocks can differentiate your offering. A white-label electricity tariff under your brand can help customers turn flexibility into lower energy prices. Pre-pooling can bundle customers' existing and new storage units and market them jointly. In this way, installations you have already built may create additional value. eRevo AG Energy Revolution remains in the background, while you retain the customer relationship.

What your company gains from it.
More order value per project and more loyalty per customer. Five levers turn your PV business into a broader system business.
Larger orders
The margin moves into the solution. Storage, heat and system technology can increase the order value per project while the module margins continue to shrink.
The argument in the price war
Where modules are interchangeable, the system can make the difference. You can quote what competitors may not offer, namely long-duration storage, heat and flexibility from a single system.
Rescued projects
Stalled quotations may become signed contracts. Clients who are concerned about low or negative feed-in prices receive a viable business-case calculation.
Your own electricity tariff
White label under your brand. Customers can receive lower-cost energy while you build customer loyalty across the service life of the installation.
Pre-pooling
Every installation may create additional value. Existing smaller storage units can also be bundled and marketed jointly on the electricity market.
Your customers ask where the electricity should go. Give them the answer.
Offer a white-label electricity tariff under your own brand and help customers turn flexibility into lower energy prices. Current figures under discussion range from 14 to 20 centimes per kWh, including grid fees. Pre-pooling combines existing and new storage units and markets them jointly. Some solar companies already show how strongly this proposition can support sales. With us, you can offer it without building your own energy company.
We remove complexity and improve profitability.
Your partner in the background.
eRevo is a system architect and energy specialist, not an installer. The installation and customer relationship remain yours. We provide the system and the business models behind it.
One system, one point of contact.
System architecture, design, tariffs, pooling and conformity from a single source, implemented with our ecosystem of component, contracting and specialist partners.
Proven in live operation.
The world premiere installation in Eich has been operating at full load since April 2024 and is open to visits with your customers, by arrangement. Six years of development work have made eRevo AG Energy Revolution the pioneer of decentralised multi-energy systems in Europe.
