Why have an on-site survey?
Installing a Solar Power System — with or without an integrated Battery Energy Storage System (BESS) — without an on‑site survey is a significant risk for both the investor and the installation company. If you receive a quote prepared without physically assessing the installation location, the final price may differ slightly or even significantly. This is not an error — it’s an unavoidable reality of working without accurate site data.
That is why, at Gershoj Energia Kft., we insist on visiting the installation site before providing a final offer. A precise on‑site survey ensures correct system sizing, realistic yield expectations, accurate installation planning, and ultimately a smoother, more predictable project for all parties involved.
What Becomes Clear During an On‑Site Survey?
During an on‑site survey, several essential technical and practical aspects of your Solar Power System — and any integrated BESS — are assessed. These include:
Rooftop suitability
Whether your roof is structurally suitable for installing solar panels, including the roofing material, roof pitch, load‑bearing capacity, and whether a support structure is required.Shading analysis
Identification of any shadow‑casting elements such as nearby buildings, chimneys, or trees that could reduce system performance.Fire protection requirements
Whether a fire protection switch needs to be included in the system — an important safety consideration that can significantly influence total system cost, making early clarification essential.Grid capacity and connection needs
Whether grid expansion is necessary based on the building’s phase capacity. Understanding the “phase situation” in advance helps determine the correct inverter type and avoids delays during the authorisation process, as grid‑related decisions are made before submission.Optimal inverter placement
Identifying the best location for the inverter (and, when applicable, BESS equipment) in an area protected from moisture and excessive heat, ensuring safe and efficient operation.
“As a company that installs solar power systems, we continuously research and adopt the best materials and technologies available on the market. We ensure that these components are integrated into our systems to deliver optimal, long‑term performance.
In our projects, we apply LEAN principles to streamline processes and improve efficiency. As an example, we developed a remote‑controlled crawler robot for situations where physical access is challenging. This tool allows us to analyse roof surfaces precisely and optimise panel positioning in areas where direct inspection is difficult.” says Jan Gershoj, the Danish founder and full owner of Gershoj Energia Kft.
