Solar power for your businessCalculated on your figures.

A business has little time and many questions. Is it worthwhile? What does the system cost over its whole life? What happens when production stops? And who is responsible when something does not work?

We answer these questions before you decide. Not with a brochure, but with a site visit and a calculation based on your data. The site visit is free, and the binding quote arrives within 72 hours.

Return on investment, not a brochure

For businesses, the calculation is what counts in the end. A solar system replaces grid electricity that you would otherwise buy at the full tariff. The more electricity you use directly in the business, the shorter the payback. This is the most important lever, more important than the size of the system.

That is why we do not calculate with average values. We read out your load profile, meaning how your consumption develops over the day and the year, and size the system accordingly. This covers:

• Investment and possible subsidies
• Yield per year and share of self-consumption
• Savings compared with buying from the grid
• Maintenance and insurance
• Payback period

If a smaller system suits you better than the largest possible one, we will say so. For details on roof types, connection and subsidies, see solar systems for business.

Large roofs, high self-consumption

Halls, warehouses and production buildings usually have large, simple roof areas. On flat roofs, the modules are mounted on frames, often facing east and west. This spreads the power evenly over the day, which suits a business with working hours in the morning and the afternoon.

Before planning, we check the structure, the roof build-up, fire protection and the condition of the roof membrane. If a refurbishment is coming up, we plan the roof and the solar system together. Otherwise the system would later be taken down and put up again.

Peak loads and commercial storage

Many commercial tariffs include a demand charge. It is based on the highest power you draw in a month. A single peak when machines start up can determine the bill.

Solar power alone reduces these peaks only in part, because they do not always occur at midday. A commercial battery with a control system can cut them: it supplies power when the load rises and charges in quiet periods. Whether this pays off with your tariff, we calculate before you decide. For the basics, see battery storage.

Charging for fleets and visitors

Company vehicles are often parked at the site during the day or in the yard in the evening. With EV chargers they charge with solar power and use what the system produces. Load management shares the power between the vehicles so that the connection is not overloaded and no new peak occurs.

We clarify in advance how many vehicles charge and when, whether visitors should be able to charge, and how the electricity is billed.

What we check during the site visit

We come to your premises and look at what the system will have to carry later. On the roof, these are load-bearing capacity, build-up, penetrations and access. Inside, we check the main distribution board, connection capacity and space for the inverters. We also go through shift work, weekends and company holidays with you, because they determine when the solar power is needed.

With the load profile data, we then calculate several options: a system sized to the roof area, one sized to self-consumption and, if it pays off, one with a battery. You see what each option costs and what it brings.

Installation without interrupting operations

A business cannot stop for the installation. We agree the schedule, access, storage space and power interruptions with you in advance. Work that requires the power to be switched off is scheduled for off-peak times. Our own installers carry out the work, so that you have a fixed contact person.

Subsidies and taxes

The federal one-off payment (Einmalvergütung, EIV) from Pronovo also applies to commercial systems. Larger systems follow different rules from small ones, and we check the current position. Some cantons and communes (municipalities) pay in addition. Subsidies that we handle for you can be pre-financed on request. For the tax treatment of the investment, speak to your tax adviser.

Financing and owners

If you do not want to buy, we can on request look at financing or contracting as an option for your case. If you do not own the building, the owner has to agree. Here too we help to share the investment and the electricity supply.
