· Thermal Power Plants with ”Fresnel” solution technology
· Geothermal Power Plants and similar

We provide our customers with a full portfolio of services for implementing photovoltaic installations of any size. As a general contractor, we select suitable properties and assume responsibility for all aspects of project planning and construction. To ensure maximum yields, our services also include plant operation and monitoring. Our customers can fully rely on our support for the entire duration of the project.

As soon as we have found a suitable location for your installation, we will introduce the next project steps: these include negotiating a contractual agreement with the land owner, who may be either a (co-)operator or a lessor, as well as obtaining approvals from the local authority.

In addition we will organize and settle any formalities with the regional utility company. Designing and calculating the installation, as well as accurately planning its construction and operation, are core elements in the planning phase.

Together, we will draw up an investment, financing and cost plan. Profitability calculations, which include a yield simulation, will provide you with a solid basis for deciding whether or not to proceed.

Top-class technical system design and high-quality components from renowned manufacturers guarantee superior systems which furnish the highest yields. We assign tasks to experienced subcontractors from various trades with whom we have already completed numerous successful projects. In addition to providing plants which are both functional and profitable, INESING aims to design roof-top installations which are aesthetically and architecturally sophisticated, and free-standing systems which respect the environment and protect nature.

We monitor and record the yield of your installation with the aid of a tried and tested solar monitoring system, thereby ensuring that your investment will remain profitable for 20 years or more. We also carry out regular maintenance, and have the capacity to respond quickly in the event of faults, meaning that smooth operation is guaranteed.

Our team of design and field professionals including electrical engineers, mechanical engineers, computer scientists, physicists, mathematicians, and technicians embrace each project with enthusiasm and great anticipation.
