Frequently Asked Questions
HEMA Solar supports photovoltaic projects from initial feasibility studies through technical design to construction-phase quality assurance. This includes site assessments, yield forecasts, simulations, permitting documentation, glare assessments, as well as technical inspections of existing assets. We also provide consultancy for repowering projects and the optimisation of existing installations.
Yes. Our engineering, consultancy and expert reporting services are available worldwide. Yield calculations, simulations and technical assessments can be carried out independently of location. Country-specific standards, climatic conditions and regulatory requirements are always considered on a project-specific basis.
At the outset, we define the project objectives, framework conditions and available documentation in a structured initial consultation. Based on this, we establish the scope of services, timeline and interfaces. Throughout the process, you receive transparent progress updates. The final report or design package is clearly documented and, if required, aligned with banks, authorities or investors.
HEMA Solar prepares glare assessments to evaluate potential light reflections from photovoltaic installations. The analysis is based on recognised calculation methods and takes relevant standards and guidelines into account, including those in the context of DIN 5034. We assess potential impacts on residents, transport routes and sensitive areas, and develop appropriate mitigation measures where necessary.
Our services cover the entire lifecycle, from initial concept and preliminary design through detailed engineering to commissioning and technical due diligence of existing assets. HEMA Solar works with project developers, investors and EPC contractors, as well as municipalities, commercial enterprises and private clients.
We work closely with leading companies to provide you with best-in-class solutions and the highest quality standards in the industry.
