Charge up with solar power when electricity prices are low

How dynamic tariffs and car park solar panels reduce energy costs

From 1 April 2025, the following will apply: electricity tariffs in Germany may finally be structured dynamically, including grid charges.

For companies focused on sustainability, cost-effectiveness and security of supply, this is a real game-changer.

But what does this mean in practice – and what does a car park solar installation or a solar carport have to do with it?

💡 Dynamic electricity tariffs: New opportunities for businesses

Until now, electricity prices have been fixed for most businesses – regardless of current trends in the electricity market. Under the new rules, businesses can now opt for tariffs that are adjusted hourly (or even every quarter of an hour) in line with the actual market price. This opens up new opportunities:

✅ Buy electricity cheaply when the grid has it available
✅ Avoid peak loads
✅ Better align generation and consumption

🔋 Car park solar meets dynamic pricing: the perfect combination

This is where the car park solar array comes into play. Anyone who generates their own solar power – for example, via a solar canopy over a car park, a solar carport or another commercial solar installation – can make the most of the flexibility on offer:

Use solar power directly during the day, e.g. to charge electric vehicles

Draw additional electricity from the grid when market prices are low

Avoid using grid electricity when prices are high – or even feed surplus energy back into the grid

This smart combination makes it possible to reduce electricity costs, relieve the strain on the grid and operate more sustainably at the same time.

🚗 Smart charging for e-mobility

For businesses with an electric vehicle fleet or car parks for staff and customers in particular, a solar canopy over the car park offers a twofold benefit:

You generate your own electricity directly at the point of consumption

And dynamic tariffs allow charging processes to be optimised in terms of timing

Charge your vehicles during the day using solar power and combine your self-generated electricity with grid power precisely when the electricity price is at its lowest.

All of this enables an even more cost-effective use of your PV electricity and your fleet.

📈 Cost-effectiveness and financing

The combination of commercial solar power and smart charging management becomes even more cost-effective with dynamic tariffs. Attractive solar financing models (leasing, PPAs, contracting) in particular significantly lower the barrier to entry for many businesses.

A well-planned car park power plant pays for itself more quickly today than it did just a few years ago – especially if it actively helps to reduce energy costs.

🔧 Conclusion: Build the infrastructure now to reap the benefits

Dynamic electricity tariffs are changing the game. Businesses that invest today in a solar solution for their car park, solar carports or a car park PV system are creating a strategic advantage: they gain control over their energy consumption, improve security of supply and reduce their dependence on the volatile electricity market.

Now is the right time to become self-sufficient – with solar power for businesses.
