Renewable energy for everyone!

Our customers are private persons, companies, international corporations and governments: because we make energy better!

We are qualified and certified experts in the German PV-industry. We provide specific solutions for our customers regardless of the project type: beit a large utility-scale or a home-system project, roof-top or ground-mounted. We build high-quality photovoltaic systems worldwide.
We are there for you to fulfill your wishes and requirement.

We provide the following services:

We assist you for greenfield project development:

  • Site selection and assessment
  • Cash-flow Modellings
  • Installation and Commissioning
  • Construction Management
  • Maintenance and Monitoring

Here you are absolutely right for best overviewing the range of our services for the photovoltaic industry. Please give a look further below to our individual solutions.

Besides the outdoor plants, roof-on photovoltaic systems on commercial and industrial roofs are among the areas with the highest potential .

Nearly unused roof-top areas can help to lower the electricity costs of your company: install solar-photovoltaic systems. You can profit the next decades while avoiding the steady increase of energy prices.

You can benefit of the sharp price diminishing of photovoltaic systems in the past years. Additionally through special measures such as battery energy storage, you can benefit even more if regarding your electricity costs, especially at peak load capping.

Should the investment costs be too high, you still have more opportunitys to use. A roof-top surface lease for the are to an investor can provide the advantages exposed above.
We support you assessing the different options with concepts to configure the most lucrative application for you.

Let’s talk about the potential of your building and evaluate the possibilities.

Fixed-tilt and solar tracking systems

Tracking systemsfollow the sun during the day-light hours to ensure the photovoltaic systems to have the best exposure angle to the sun. This increases the efficency with an uniaxial solution up to 30%, with an biaxial tracking solution it can reach up to 45%.

With our specialized team we can optimise the tracking systems optimally to your system. We support international companies with the implementation of such systems with our special know-how and our skills in management and planning. In 2015 and 2016 we succeeded to plan 4 projects in the MENA region constructing and commissioning them.

We differentiate between two main system philosophies:

  • the astronomical (algorythmic) : depending on the specific date: month, day and time
  • the sensor-controlled tracking systems, which dinamically track the most clearly lit spot in the sky

We can clarify which is the best suitable solution for your application. Just contact us.

Small Plants

Reduce costs and produce your own electricity

You can save up to 50% costs and reduce also the CO2 output on your own roof top.

Using a storage system, you can increase the efficency and you can produce up to 100% of your own electricity. This gives you more independency from the electricity grid and the associated steadily increasing energy prices.

Be independent with self-sufficient systems.

Stand-alone facilities are the finset art of designing and planning power supply. Designing them is no problem for our espert team:

The configuration of such complex system requires the adjustment of many components to be coordinatedwith each other. Designing the suitable interaction of photovoltaic compnents with wind, generators, storage systems of different typologies, considering the required load profiles, is the passion of for our experts. For years we take care of our costumers’ projects and develop unique solutions, to statisfy them.

We can design and configure your individual stand-alone system: of any size and for every application, just contact us.

We clean your solar PV-plant

There are many types of pollution in photovoltaic systems, which reduce the yield of the plant by up to 10% to 20%: coarse dirt, such as leaves, needles, small branches or animal excrement, but also finer dirt such as bepielsweise bee pollen, air pollution settles or minerals from the rainwater.

By cleaning the system, the attached dirt is removed and the yield raises to the normal level.

Especially plants operating close to agricultural or industrial plants, near highways or forests, should be cleaned in a regular cycle.

If a cleaning is carried out by us, we recommend at the same time also to apply a nano-coating. This coating prevents dirt and dust from settling into the surface of the system, making it easier to remove through rain or snow. In addition, you can extend the cycles between cleaning.

We clean your plant fast and professionally observing all safety standards and regulations.

With know-how, specialized personnel, the right equipment and gentle cleaners, which were developed especially for the surfaces of photovoltaic plants you get a premium service for the surface of your photovoltaic modules.

Self-cleaning by snow and rain

While it is true that snow and rain clean the system to some extent, much of the contamination remains adhered to the surface. In addition, the angle of inclination of the modules must be greater than 12 ° for this self-cleaning to work.

The cleaning power of rain and snow can be significantly increased by applying a nano-coating.

Ask us about the necessity and implementation of a cleaning or send us your order. We are always available by phone or e-mail.
