Clarify issues with drone aerial photography and regenerate asset value! Create precise power generation forecasts based on 3D data and propose plans such as repowering and FIP conversion.
"Electricity sales revenue has drastically decreased due to output control," "I want to reduce the effort required for inspections," "I want to repower equipment that has deteriorated over the years"… HSK, with over 10 years of development experience and a total of more than 500 projects, offers optimal operational plans for all challenges faced by low-voltage solar power plants. In particular, power plants constructed at the beginning of the FIT system often had insufficient consideration for panel layout and surrounding environments, resulting in cases where "the expected power generation does not materialize." Therefore, our company conducts thorough investigations from above using drones. We identify the "true culprits" of power generation decline that are difficult to see from the ground and connect them to improvement measures that maximize potential. <"Terrain" and "shadows" are fully digitized to visualize power generation potential> Our use of drones is not just for aerial photography. We recreate the local terrain and equipment as three-dimensional data and conduct advanced analyses. We precisely simulate the impact of shadows caused by tree growth and power loss at the level of individual panels, allowing us to formulate evidence-based business plans. *Support for improving profitability after Solar Re-Value is also available.

Applications/Examples of results
<Case Study> Challenge: After purchasing a used FIT project, it was found that shadows from nearby trees and weeds were causing lower than expected power generation. To accurately assess the impact of the shadows, aerial surveying using drones was conducted, resulting in the "3D data" of the power plant and its surrounding environment. Traditional 2D design plans do not take into account the height of trees or the undulations of the terrain. However, by utilizing 3D data, it is possible to precisely simulate "where and to what extent shadows fall" throughout the year, especially during the low solar altitude in winter and during morning and evening hours. Based on this analysis, we proposed the optimal panel arrangement to avoid the impact of shadows. Even owners without specialized knowledge were able to visually understand "why it was necessary to change the arrangement," allowing us to proceed with the renovation work. As a result of the repowering, the electricity sales volume increased by approximately 20%. By adopting SolaX's hybrid power converter, which allows for the expansion of battery storage, it is now possible to consider the installation of additional battery storage in the future, depending on the occurrence of output control situations.
