Use rooftops profitably.

By using photovoltaics in business, entrepreneurs benefit in many ways: they save electricity costs, reduce their CO2 emissions and make an active contribution to the energy transition. Solar power produced in the business can be consumed, stored and/or fed into the public grid.

You are a business owner or have suitable roof space? Then we would be happy to advise you on customised photovoltaic solutions.

1. Contact & Advice

In the first step, we would like to get to know you. Together we will discuss your needs, requirements and questions about your upcoming solar project. Please contact us by phone or via the contact form – without obligation and in a straightforward manner.

2. Design & Presentation

After a successful contact, we deal intensively with your requirements and plan a photovoltaic system tailored to your commercial space on the basis of your individual load profile and the energy costs incurred. We present our design (incl. profitability analysis) to you either online or directly on site.

3. Offer & Realisation

Afterwards, you will receive an initial free and non-binding offer. If you decide to work with ErEne on the basis of this offer, we can get started! Further project planning and realisation will begin in a goal-oriented and transparent manner. During the entire process, we are available to you at all times.

Frequently asked questions.

Is an investment in a solar system worthwhile?
Basically, investing in a solar system is worthwhile especially if a lot of electricity is consumed. You can pursue the following goals by installing a PV system:

  • High self-consumption: Use the self-produced solar electricity in your company. Through the additional use of electricity storage, you can achieve particularly high self-consumption quotas.
  • Feeding electricity into the grid: Alternatively, you can feed your solar electricity into the public grid. In Germany, for example, you receive a so-called feed-in tariff which is fixed for 20 years from the month of commissioning.

If you have any further questions on the subject, you can contact us at any time.

Power outage - do storage units and PV systems provide emergency power?

Yes, in combination, the solar system and battery storage provide a secure emergency power supply for your company. The storage system works with a certain reserve. This means that the storage system only discharges up to a certain point. The reserve then supplies the emergency power in the event of a power failure.

Is a battery storage system worthwhile for my company?

The use of battery storage systems has several advantages. Especially if you aim for high self-consumption quotas with your PV system. Depending on the capacity of the chosen storage system, the solar power produced during the day is also available to you when it gets dark. Companies that consume a lot of electricity at night, for example, can thus significantly reduce their electricity costs.

Battery storage also plays an important role in peak load capping. Here, the required energy is called up from the storage system and not from the public grid during times of significantly increased electricity consumption. This allows peak loads to be compensated dynamically.
