Solar optimization for a construction company in Dalfsen

A construction company with a high-volume electricity connection wanted to increase the output of its solar installation and reduce costs. We installed a BOLT-40 battery that stores solar energy and strategically deploys it through imbalance trading and EPEX.

These are the results so far

  • Better efficiency from solar panels
  • Expected annual revenue of €15,000 to €20,000
  • Smart strategies for dealing with price spikes
  • Less energy fed back into the grid

Rated output power.

The maximum power per unit.

300–500 kW

Here's how the process went

1

INSIGHT INTO CONSUMPTION

We tracked when and how much electricity was generated versus consumed.

  • Clear data as a foundation
2

INVESTMENT ADVICE

We calculated the financial returns from battery storage and market participation.

  • Estimated annual value between €15,000 and €20,000
3

INSTALLATION & INTEGRATION

The battery was connected to the existing solar system and hooked up to the meter box.

  • Smart energy storage without modifying systems
4

REAL-TIME MONITORING

Customers can see in real time how much energy is being stored, used, or traded.

  • Full control and a new source of revenue

We resolved these issues for the customer

The construction company fed much of the solar power it generated back into the grid. As a result, it earned almost nothing, even though the electricity was actually consumed at other times.

The battery now stores the electricity and releases it only when there is internal demand or when market prices are high.

Customer review

“Our solar energy is really paying off for us now. We’re making money instead of just feeding power back into the grid.”

Construction Company

SOLAR ENERGY YIELDED VERY LITTLE

The electricity generated was routinely fed back into the grid, often at very low rates. The battery now provides smart storage and can be used at strategic times.

NO STRATEGIC USE OF ELECTRICITY

There was no link between generation and consumption, which resulted in structural losses. With real-time software, electricity is now tailored to both demand and the market.

UNRECOGNIZED FAIR VALUE

The customer did not actively respond to price fluctuations and thus missed out on structural revenue. Now the system automatically adjusts based on imbalance and EPEX market prices—without any extra work.

Frequently Asked Questions

Can't find your question here? Please contact us.

How does battery storage work in combination with solar panels or wind energy?

Our battery stores excess energy locally whenever more energy is generated than is consumed. This energy is then automatically used during periods of higher demand or when market prices are favorable.

Can I make money through energy trading?

Yes. Stored energy can be sold intelligently through the imbalance and EPEX markets. Our software (BBox) automatically manages this process, allowing you to benefit from price fluctuations without having to lift a finger.

How much maintenance does the system require?

Virtually none. Our systems are monitored and controlled remotely. Any necessary maintenance is flagged in advance. This means you get maximum efficiency with minimal effort.
