With technical support during the construction phase, we offer you a fully comprehensive service package for your photovoltaic project to ensure the quality of execution and the conformity with the planning documents.
Ensuring sustainable success
As PV specialists, we offer you extensive consulting services in this context and, as an independent service provider, we represent your interests exclusively. Our extensive experience in the field of both plant planning and plant operation enables us to enter into dialogue with the general contractor, on an equal footing. Even in the case of short-term decisions that must be made, we are at your side to provide you with well-founded, pragmatic assistance.
When does construction supervision make sense?
We can ensure that your PV plant plan is executed perfectly and in strict accordance with the planning documents, regulatory requirements and recognized rules of technology, in order to circumvent any early issues.
If you have never developed a PV plant or been involved in solar construction before, we can use our experience as independent PV experts to help you avoid common mistakes and maximize yield and efficiency from the beginning of your project.
We offer extensive consulting services and can represent your interests exclusively. We are able to enter into exchange with your general contractor on an equal footing, thanks to our experience and expertise in the planning and operation of solar power plants.
If you had to change your contractor during the construction phase for some reason, an independent assessment is an excellent opportunity to review the original technical documentation to ensure that it conforms to best practice recommendations, and to monitor and supervise the construction work already completed, making the transition to a new contractor simple and seamless.
What makes our construction supervision stand out in the crowd

Monitor progress with drone technology
We use solar drone technology to give you a comprehensive view of your entire site, allowing you to monitor construction progress from multiple angles and vantage points throughout the construction process.
Detecting defects at an early stage
During the construction of a solar power plant, nothing goes unnoticed under the watchful eye of our experts. Any potential defects are spotted and fixed early on, ensuring that the entire operation runs smoothly from the very beginning.


Checking of all plant documentation and support during commissioning
We will carry out a thorough review of all the solar plant documentation, to ensure comprehensiveness and adherence to all regulations and specifications. Upon completion of your solar construction project, we will also follow up by conducting a visual inspection of the work, preparing a deficiency list and checking that the corrections are done properly.
