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 by identifying and replacing them at the panel level, you can start selling electricity in optimal condition. Furthermore, the inspection results will include a formal report with EL images of the inspected panels, clearly indicating where the cell cracks are located on which panels. 【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 where the cell cracks are located on which panels *For more details, please refer to the PDF document or feel free to contact us.

At Yamashita Electric Co., Ltd., we offer the '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 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 ■ Recovery of power generation ■ Efficient replacement of defective panels *For more details, please refer to the PDF document or feel free to contact us.

Yamashita Electric Co., Ltd. offers "Low Voltage Power Plant EL Inspection." By adding this inspection to regular inspections and visual checks, it is possible to detect PID (Potential Induced Degradation) and cell cracks that were previously unnoticed. 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 ■ Measures to prevent accidents caused by overheating or fire *For more details, please refer to the PDF document or feel free to contact us.

"R-SIP" is a suitable inspection program for checking the current status of rooftop solar power panels. Hotspots (abnormal heat generation) caused by dirt, cracked glass, or broken 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 start of power generation" or "It is a leased rooftop power plant," please feel free to contact us. 【Features】 ■ Suitable for checking the current status of rooftop solar power panels ■ Targets rooftop solar power plants on commercial facilities such as factories and warehouses ■ Services are contracted after confirming compliance with aviation laws and other relevant regulations *For more details, please refer to the PDF materials or feel free to contact us.

The "Trial Pack 3" is an effective EL measurement for detecting PID (voltage-induced output degradation phenomenon) and cell cracking. With a preliminary measurement limited to 3 strings (approximately 50 panels), we can accurately determine the necessity of a full 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 opinion. 3. If a full inspection is deemed 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 our on-site EL measurement service. Solar power plants exposed to disasters far beyond expectations not only face 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 countermeasure against secondary damage risks. Furthermore, if you have already subscribed to property insurance for the power plant, you can claim insurance for repair costs. Let's achieve accurate situation assessment and efficient recovery. 【Features】 ■ Utilizes on-site EL measurement service ■ Effective in avoiding secondary damage ■ If you have subscribed to property insurance for the 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 abnormal areas 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 is possible to evaluate the performance of solar cells. Additionally, through simulations, it can estimate lost profits, allowing for the assessment of asset value based on not only past 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 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.
