ヤマシタ電気 List of Products and Services

Yamashita Electric Co., Ltd. offers "EL Inspection." By adding this inspection to the completion inspection, it becomes possible to detect cell cracks that were difficult to identify in traditional completion inspections, and to identify and replace panels on a unit basis, allowing for the start of power sales in optimal condition. The inspection results will include a formal report with EL images of the inspected panels, clearly indicating which panels have cell cracks and their locations. 【Features】 ■ Confirm cell cracks while the panels are installed ■ Inspect a large number of panels in a short time ■ Create a formal report with EL images of the inspected panels ■ Clearly report which panels have cell cracks and their locations *For more details, please refer to the PDF materials or feel free to contact us.

At Yamashita Electric Co., Ltd., we offer 'EL Inspection' that can enhance the asset value of power plants. By incorporating this inspection into the due diligence process to assess the value of power plants, we can provide a more specific and objective valuation. Additionally, we can identify issues (such as PID and cell cracks) that were previously undetectable. Furthermore, we assist in evaluating the feasibility of the project by estimating the balance between damage costs and repair expenses. Please feel free to contact us. 【Features】 ■ Ability to present a more specific and objective value ■ Advice on repair methods ■ Support for feasibility studies by estimating the balance between damage costs and repair expenses ■ Restoration of power generation ■ Efficient replacement of defective panels *For more details, please refer to the PDF document or feel free to contact us.

• Contract Inspection

Yamashita Electric Co., Ltd. offers "Low Voltage Power Plant EL Inspection." By adding this inspection to your regular inspections and visual checks, it is possible to detect PID (Potential Induced Degradation) and cell cracks that you may not have noticed before. This allows for measures to recover reduced power generation and prevent accidents caused by overheating or fire. Additionally, we provide advice on suitable repair methods as an option. 【Features】 ■ Ability to detect unnoticed PID (Potential Induced Degradation) and cell cracks ■ Recovery of reduced power generation ■ Ability to implement measures to prevent accidents caused by overheating or fire *For more details, please refer to the PDF document or feel free to contact us.

• Contract Inspection

"R-SIP" is a suitable inspection program for rooftop solar power plants to check the current condition of rooftop power generation panels. Hotspots (abnormal heat generation) caused by dirt, broken glass, or cracked cells can pose a risk of fire in the worst-case scenario. If you have concerns such as "I have never seen the panels since the power generation started" or "It is a rented rooftop power plant," please feel free to contact us. 【Features】 ■ Suitable for checking the current condition of rooftop power generation panels ■ Targets rooftop solar power plants of business facilities such as factories and warehouses ■ Services are contracted after confirming that there are no violations of aviation laws or other relevant regulations *For more details, please refer to the PDF document or feel free to contact us.

The "Trial Pack 3" is an effective EL measurement for detecting PID (Potential Induced Degradation) and cell cracking. With a preliminary measurement limited to 3 strings (approximately 50 panels), we can accurately determine the necessity of a comprehensive inspection. This allows for the dual achievement of securing revenue from electricity sales and the efficient management of maintenance costs. "We need justification for expenses that exceed the initial budget for maintenance costs." "We are concerned about cell cracking damage after typhoons or heavy snowfall." This service is recommended for customers with such concerns. 【Process】 1. Decide on the 3 strings to be measured in advance and conduct the inspection. 2. Report the inspection results to the customer and explain the expert's insights. 3. If it is determined that a comprehensive inspection is necessary, we will provide a new estimate. *For more details, please refer to the PDF document or feel free to contact us.

At Yamashita Electric Co., Ltd., we offer "Cell Crack Damage Investigation" utilizing on-site EL measurement services. Solar power plants exposed to disasters far beyond expectations face not only a decrease in power generation but also an increased risk of fire. To avoid such secondary damage, "EL inspection" is effective. By adding this to conventional visual inspections, it serves as a measure to mitigate the risk of secondary damage. Furthermore, if you have already subscribed to property insurance for your power plant, you can claim insurance for repair costs. Let's achieve accurate situation assessment and efficient recovery. 【Features】 ■ Utilizes on-site EL measurement services ■ Effective in avoiding secondary damage ■ If you have subscribed to property insurance for your power plant, you can claim insurance for repair costs *For more details, please refer to the PDF document or feel free to contact us.

"On-site EL measurement technology" is a technique that allows for the immediate identification of abnormalities in solar cells. By combining it with visual inspections, I-V measurements, and inspections using thermal cameras, it enables more effective and accurate detection of solar cell defects. By capturing defects that cause a decrease in power generation, it allows for the evaluation of solar cell performance. Additionally, through simulations, it can estimate lost profits, enabling the assessment of asset value based on not only past power generation performance but also projected future sales revenue. [Features] - Confirms defects in solar cells and guarantees construction quality - Maximizes the power generation capacity of the solar power plant from the time of completion - By combining with visual inspections, I-V measurements, and inspections using thermal cameras, it enables more effective and accurate detection of solar cell defects *For more details, please refer to the PDF document or feel free to contact us.
