Frequently Asked Questions
The duration of solar project planning depends on the system size, complexity and permitting requirements. While the technical engineering of a rooftop photovoltaic system can often be completed within a few weeks, ground-mounted PV projects typically require more time due to grid connection assessments, site analysis, yield calculations and coordination with authorities.
HEMA Solar ensures efficient, transparent and reliable project delivery through structured processes and clear project coordination.
To develop a well-founded photovoltaic design, HEMA Solar initially requires site-specific documentation. This includes site plans, cadastral extracts, roof layouts or plot data.
In addition, information on the grid connection situation is essential, and for self-consumption systems, details on electricity demand are also required. For ground-mounted projects, geotechnical data may also be relevant.
The more complete the initial data, the more accurately yield forecasts, simulations and financial assessments can be carried out.
The process begins with a detailed site analysis, which forms the foundation for the entire solar project. This is followed by shading analysis and the technical sizing of the photovoltaic system, including the selection of suitable modules and inverters.
Building on this, HEMA Solar prepares a reliable energy yield forecast and a financial assessment. In addition, grid connection concepts are developed and all relevant permitting documentation is prepared, ensuring that the photovoltaic system is technically optimised and delivers long-term economic performance.
In principle, HEMA Solar’s engineering services are available worldwide. As yield calculations, simulations and technical system design can be carried out independently of location, solar projects across Europe and internationally can be professionally supported. At the same time, we take into account climatic conditions, country-specific standards and regulatory requirements to ensure safe and compliant project delivery.
At the outset, HEMA Solar works closely with the client to analyse the project objectives, framework conditions and technical requirements. Based on this, a tailored scope of services is defined, including a clear timeline and defined interfaces.
Throughout the engineering phase, you receive regular progress updates to ensure full transparency and planning reliability. Upon completion, all technical documentation, simulations and calculations are provided in a structured format, enabling a smooth process for permitting, financing and implementation.
