EV charger sharing: 10x more profitable than the highest feed-in tariffs

Why exporting solar power pays less and less across Europe

Maximising self-consumption of your solar energy remains important. But on sunny days, most households simply produce more electricity than they can use themselves.

At that point, exporting to the grid becomes unavoidable. Unfortunately, it is often barely profitable. In many European countries, the net feed-in tariff ends up around €0.03 per kWh. Even the highest feed-in tariffs deliver only a limited return, especially because solar power is exported most when supply is high and market prices are low. As grid costs increase and compensation mechanisms are adjusted, the net earnings from export remain under pressure.

Increase your earnings from €0.03 to €0.35 per kWh

A powerful alternative to exporting solar energy is sharing your home EV charger. Instead of sending electricity to the grid, you use your solar power to charge other drivers’ electric vehicles. This can be far more rewarding:

You earn around €0.40 per kWh

You pay a 15 percent commission

Your net earnings are around €0.35 per kWh

That is more than ten times what you typically receive from a feed-in tariff.

With the number of electric vehicles growing rapidly across Europe and public charging prices remaining high, sharing your charger is becoming increasingly attractive. If you have a private driveway or another accessible parking space, your charging point is often already suitable for sharing.

How does sharing your EV charger work?

With the Voltbee app, sharing your charger is straightforward:

1. You set your own prices and availability
2. A driver requests a charging session
3. You choose whether to accept the booking

There are no startup costs and no long-term commitments, and you always stay in control. At the same time, you actively support the energy transition and help reduce grid congestion by using locally generated electricity locally.

Will feed-in tariffs increase in the coming years?

In countries such as France and Germany, feed-in tariffs are closely linked to policy decisions and market conditions. While support schemes continue to exist, new installations often receive lower compensation than older ones and future adjustments are uncertain.

What really matters is your net return per kWh. Even when the official feed-in tariff looks reasonable, the actual income is often limited because export takes place during periods of low market prices. As a result, many solar owners across Europe experience declining or stagnating export revenues rather than growth.

Is a dynamic energy contract the solution?

Dynamic or market-based energy contracts can reduce some costs and better reflect real time prices. However, solar households still export most electricity during periods of oversupply, when prices are lowest. This means that even with dynamic pricing, the income from exporting solar power often remains modest.

That is why sharing your EV charger is attractive even with a dynamic contract. By making your charger available when electricity prices are low and solar generation is high, you convert surplus solar power into direct revenue instead of accepting a low feed-in tariff. Sharing your charger fits perfectly with the European goal of balancing supply and demand more efficiently and significantly increasing your own returns.
