Frequently Asked Questions
Owner’s engineering in the photovoltaic sector includes independent technical and commercial support throughout the lifecycle of solar projects. We assess feasibility, system design, financial viability, energy yield forecasts, technical concepts and EPC proposals. In addition, HEMA Solar supports tendering processes, contract review, permitting matters and quality control. The objective is to minimise investment risks and ensure the long-term performance of the photovoltaic system.
Owner’s engineering for photovoltaic projects should ideally be involved during the concept and design phase. The earlier an independent solar engineer is engaged, the greater the potential for optimisation in terms of site assessment, system layout, financial modelling and technical design. Early involvement reduces planning errors, avoids additional costs and increases confidence in investment decisions.
The cost of owner’s engineering services in the solar sector depends on the project size, complexity and scope of services. Smaller rooftop systems require a different level of input compared to large-scale ground-mounted photovoltaic plants. Services are typically priced either as a fixed fee or on an hourly basis. Through optimised planning, engineering and contract structuring, these costs are often offset at an early stage of the project.
Professional owner’s engineering enhances photovoltaic projects both technically and commercially. This includes reviewing energy yield assessments, evaluating inverter and module concepts, conducting shading analyses, performing financial assessments, and verifying proposals and technical specifications. Independent technical due diligence by HEMA Solar helps to avoid yield losses, design flaws and unnecessary capital expenditure.
An owner’s engineer such as HEMA Solar offers extensive expertise in photovoltaic system design, yield modelling, standards and regulations, grid connection requirements and project management. This includes technical simulations, expert reporting, glare assessments, construction-phase quality control and the evaluation of existing assets. This interdisciplinary expertise enables a holistic approach to solar projects from the owner’s perspective.
