Solar Power Plant Design

Good design results in an efficient plant with a long lifespan

The power plant designing is an integral part of a building application for both commercial and company solar power plants. We take local conditions and requirements into account when our solar power plant system design, so we can give you the best chance of approval for your building permit.

Sound system planning ensures maximum yield, high performance and efficient and practical operation. It also anticipates future challenges and takes potential problems into account, for example, those arising from the site. This saves you effort, time and costs in the long run.

Do you need to add design of a power plant proposal to your yield assessment?
An accurate and realistic proposal for a commercial solar power plant design is an important part of an energy yield and solar performance analysis, which is why we have developed our own system design, which is optimized for most areas in Europe, in terms of mechanical occupancy and electrical wiring. We develop our designs using PVcase software, which allows us to make a 3D model, taking the exact topography of the surface into account.

Our design approach is based on a thorough analysis of the site and its surrounding environment, including factors such as sun exposure, shading, wind patterns, and more. By using this information, we can create a design that is tailored to the specific needs and requirements of the project, ensuring optimal performance and efficiency.

We also pay close attention to mechanical occupancy and electrical wiring, as these factors can significantly impact the overall performance and reliability of the system.

In addition to the site conditions, the selected solar power plant design also plays an overriding role. The design and positioning of the modules determines how much irradiation hits the PV generator. greentech uses a standard module table design and then adapts this individually to the local conditions.

The perfect design for your area

We provide you with the ideal individual design for your area. You benefit from our in-house system design, which is optimised for the allocation planning of areas in the European region and is continuously adapted to suit the latest technology. On this basis, we create the best possible design for your PV system, in terms of location and yield, through various iterations and simulations.

We have our own department for engineering projects

We have established an autonomous department for our engineering projects. Here, our engineers and PV experts apply the knowledge and experience they have acquired in the solar power plant industry in specific areas such as plant design. This is where technical and practical expertise converge to deliver plant designs that ensure long-term success on every level.

Use of appropriate 3D software for fast, reliable results

We use the 3D software, PVcase, for our plant design. It automatically determines the allocation, down to the centimeter, swiftly delivering the desired results. On this basis, further changes in the parameters that determine the design, such as row spacing or tilt of the modules, can also be implemented. Different examples of designs are then tested for their expected yield, using a simulation software, which makes it possible to compare them. This enables us to create the perfect design for your specific area.

Best practices through memberships of associations and committees

We are always up to date with the latest innovations in solar system design and new developments in components and technical solutions. For this purpose, we are members of various associations and committees, and we attend further training courses on a regular basis.

The perfect plant design – profitable and practical
In order to determine whether a certain field or roof area is suitable for a new photovoltaic project, an initial solar system design is usually created. It takes the available site information into account and indicates a standardized layout design, for example by using defined module tables and standard electrical wiring.

Today, 3D layout planning software is usually used to create the plant layout. If the area basically shows potential for a photovoltaic system, the layout is optimized in the next step. For this purpose, various parameters of the initial planning are refined, for example, to better utilize the area or to further increase the possible yield.

A good system design is decisive for the achievement of the best possible yield later. It forms the basis for the subsequent yield assessment, and it is also a fundamental component of the application for a building permit.

Frequently asked questions

Ask everything you need to know about Yield assessment

What factors should be considered when planning a PV farm/plant?
When considering the external factors of topography and shading objects, it is important to define the ideal layout for the site-specific conditions. For example, the choice of the substructure must be in line with the requirements for the local soil and building permit. In the case of external shading objects, these must be considered for the layout to minimize shading of the modules. The interplay between components, electrical connections, row distance, angle, and Azimut must be taken into account in order to reach an optimal design both in terms of yield and operation and maintenance requirements. Our 3D design software allows us to achieve a very high level of detail and can run many iterations to come up with the best site specific design.
What is the timeline for getting a plant design?
The timeline largely depends on the size and complexity of the project. As a rough estimate, 2-3 weeks for reviewing the documentation, coordination with the customer and beginning with the actual design would be realistic. The design itself, including internal review processes, will take about 1 week to complete.
How much does a plant design service cost?
This also depends on the individual project. In general, the provision of a well-founded design, including all relevant parameters, starts from EUR 2,500.
Which planning software do you use?
We use PVcase software, which is a highly automated 3D design tool. Furthermore, we have also created our own greentech plant design, which is optimized for most sites in Europe, in terms of mechanical layout and electrical wiring. We optimize our design fundamentals continuously, in order to be at the forefront of technological developments.
I already have a plant design but need an independent check on this one, can you help me?
Of course! In our role as owner’s engineer, we regularly perform independent reviews of designs for external plants. This includes a critical review of the general layout, a check of normative compliance and best practice engineering.
Can you recommend a material supplier in line with your plant design?
As an independent service provider we are not focused on single suppliers, but we always provide a choice of tier 1 suppliers, based on the project-specific requirements.
