Process & Tools
We offer a broad range of services for all planning phases in order to deliver the optimum PV power plant layout. Planning work for a PV power plant is usually split up in different phases: preliminary layout, modification of layout, detailed layout and adaption during construction. To achieve this goal, our experienced team of project engineers and draftsmen utilises latest software such as AutoCAD Civil 3D, Helios and PVSyst.
Since our partners provide different mounting solutions, a part of the technical design is the selection of the optimal framework with regards to electricity generation and land utilisation. Subject to circumstances, cabling can represent a significant portion of the project cost and we are able to minimise this with appropriate design and positioning of the mounting racks, inverters, switchgear in relation to each other and the grid connection point.
The string layout for the PV power plant is defined according to geographical situation and local conditions such as solar irradiation and temperature profile. Furthermore PV modules and inverters are selected so their characteristics maximise performance with the given string layout. In addition, local conditions are considered when selecting a mounting structure as reinforced structures or deeper foundation may be required due to snow and wind loads.
Shading of PV modules and strings decreases overall yield and revenue of ground-mounted as well as roof-mounted PV systems. Therefore, shading-optimised layout is key to economic success of every project. Our team engineers every project using sophisticated analytical methods to ensure shading-optimised layout even on hilly ground. This is done by appropriately partitioning the power plant area and adjusting the distance between each row and area individually while taking shading into account. Following this approach installed power is optimally adapted to fit available PV power plant area while shading-related yield losses are reduced.
