Pushing the Limits in Electroluminescence (EL) Testing of Solar Panels

How should the hand test be done? How much detail do we need in the EL photo? We were puzzled by many questions, such as, if we can take a photo to see what details we can see, we can see whether it complies with the quality guidelines in panel production.

The EL test journey also brought with it a lot of trial, error and learning.

In order to take an EL photo, you first need to know what EL is. EL is not just a photo you can take with equipment; you need to turn a solar panel into an electroluminescence (EL) source. In other words, we energize the solar panel and turn it into a UFO heater. “What do you mean?” I can hear you ask. Yes, we light the solar panel like a lamp to take this photo.

Since the photo is a long exposure, you apply this voltage for about 10 seconds, so nothing happens to the panel, but if you apply it for a long time during the test phase, you will burn the panel. Don’t try it yourself at home 🙂

After learning the technology thoroughly, we built our own small test station and started our first trials.

Even though this EL photo was not clear and did not have enough pixel detail, it was an indication that we were on the right step. We immediately went to the field and made our first test.

Sahada ilk Elektrolüminesans EL testi çalışmalarımız — First works on the field

One night we conducted our first experiments at the facility of a company where we regularly carry out O&M processes. The goal was to use RaspberryPi to push files to the cloud and process them there.

At this stage, communication and machine learning technologies were ready to be used. The infrastructure was there, but the images were not of high enough quality. So how do we define quality? How high quality should an EL photo be?

We took the records of a factory capable of taking high-end EL photography as a benchmark.

Our aim was to capture at least this image quality in the field. For this reason, a serious sensor/lens hunt started for us. Which sensor should we use with which settings? Which feature of which lens should we utilize? Which filters were necessary, we went on a long journey. In every EL photo we took, we looked for the next step, which I believe we have reached at some point. But the solution was not only hardware-based.

In addition to off-the-shelf EL hardware solutions, you also need a post-processing process to get the required values in the image, so it’s both a hardware and software problem.

So where did we come from? Good question. See below the first and the last photo we took of the same panel.

Isn’t the difference enormous? Where have we come from? Today, there is a very serious optical quality and optimization with software. We have a photographic technique that allows us to see even the finest details on the cell.

Moreover, our Raspberry device in the system can receive this data and send it to the cloud, where a python code analyzes and interprets it. Today, we developed the device you see above, we wrote the necessary photo manipulation codes and we are developing cloud applications. Maybe 5 years ago, these were dreams. Where is technology going?

Do not damage the panel while mounting the panel. All will be revealed when we come to the EL test 🙂

Employer Engineering in Solar Power Plants

It’s time to build a solar power plant and generate your own electricity. In this process, with our employer engineering service, we technically manage the entire process for you and help you get the best out of the facility you will build.

You can find our technical engineering service scope for SPPs below. If you have any questions about our scope of services, you can contact us here or send us an email.

1. Pre-Construction Period

1.1. Design Selection and Yield Analysis

Optimum shading distances, angle values, dead zones and the associated potential installed power values are determined based on the structure of the roof or terrain.

The meteorological data set (radiation, temperature, etc.) required for SPP generation analysis is compiled. In order to create the data as close to reality as possible, 4 different data sets are utilized and sensitivity analysis is performed.

The biggest loss factor in rooftop SPPs is shading and shading analysis needs to be performed in detail. At this stage, we calculate shading losses by drawing both the obstacles on the roof (chimney, lighting, etc.) and geographical obstacles (mountain, tree, etc.) in 3D. Even in the same region, shading may vary according to the structure of the surrounding land. Since these will have a direct impact on production, their analysis should be done professionally.

The equipment used in solar energy facilities (solar panels, inverters, etc.) vary technologically. These different technologies are evaluated and appropriate installed power values and design are analyzed.

1.2. Financial Feasibility Study

A financial model that works in harmony with technical inputs is a strategic decision support tool for investments. In this respect, cost analysis is performed for all design alternatives. Bids received from EPC companies are included in the cost analysis and a project-specific financial feasibility model is built. Internal Rate of Return (IRR) and Net Present Value (NPV) results are calculated by running the model and reported to the Employer.

1.3. Control of Conformity of Technical Documents to Relevant Standards

Technical specifications are very important for a flawless installation application. After the project design studies are finalized, the compliance of the EPC and O&M technical specifications with the relevant standards for the SPP project is checked. It also clarifies the methodology to be used in calculating the project’s PR.

1.4. Approval of Final Projects

After the selection of the EPC, the projects to be drawn by the EPC are controlled and approved by us, and the approval of the projects by the EPC to the relevant institutions is supervised.

2nd Construction Period

Construction period engineering services are the processes that include the design and supervision of the processes that will take place during the investor company’s solar power plant investment and the commissioning of the power plant. In this way, it is aimed to minimize the risks and prevent possible problems that may occur in the long term. It also aims to take measures to protect the rights of the investor for possible legal processes.

2.1. Determination of Technical Quality Criteria with Reference to Relevant Standards

First, a SPP project kick-off meeting is held and a construction roadmap is created. At the same time, a responsibility matrix is created to prevent problems that may arise in the later stages of the project.

Contractor requests arising from problems that arise during implementation are examined. The technical compliance of these requests is checked and communicated to the investor, facilitating decision-making processes.

2.2 Solar Panel Production Process Factory Inspections

The most important equipment used in solar power plants is the solar panel. For this reason, it is important that its production is realized in accordance with the standards. Production controls of solar panels are carried out in two stages. At the first stage, product certification control is carried out. Factory inspections are then carried out during the production process. 2.3. Inspection of Construction Processes

Regular on-site project audits are carried out for the healthy progress of the project from inception to acceptance. In this process, project progress is monitored according to the contract. Regular project visits are carried out during construction. According to the requirements of the EPC contract, construction and project progress is monitored in line with the planned schedule.

Quality controls are carried out during the production of incoming materials for the SPP plant and after shipment to the site.

All construction and assembly works are carried out in a controlled manner, as any mistake in the assembly part may become irreversible in the future. The process is regularly reported and recorded from start to finish.

2.4. Commissioning Tests

In order to monitor and measure the performance of solar power plants, it is necessary to perform tests within the scope of IEC 62446 and IEC 60891. These tests are mainly IV-Curve (current-voltage) measurement, thermal tests, insulation test, grounding test and performance measurement. After the solar power plant is installed, these tests are carried out and it is analyzed whether the plant performs as expected. You can find a detailed description of the tests here.

A report containing all the tests is prepared. This report is also a risk table. According to the report, the findings are prioritized and presented to the EPC company. Warranty processes are put in place and a new business plan is created together with the EPC company to meet the necessary conditions.

3. Final Acceptance Tests (IEC 62446)

After at least 6 months of operation of the facility, a site visit is made and visual and electrical controls are carried out according to the standards. At the same time, performance measurements of the equipment are made and it is reported to the investor whether the conditions guaranteed by the manufacturer are met. Visual inspections check for physical defects, while electrical tests check production performance.

Once the plant is in production, radiation data, production data and temperature data are processed and the overall efficiency of the system is calculated. With this calculation, the performance of the system is revealed. In the subsequent controls, degradation is also based on this data. This is a necessary data set to track any project-wide problem or excessive degradation of cells.

Safety and Risk Management in Battery Energy Storage Systems (BESS)

While Battery Energy Storage Systems (BESS) in solar power plants make renewable energy compatible and sustainable with existing grids, the safety and risk management of these systems comes to the fore. From fire risks to electrical hazards, the complex nature of BESS requires careful risk assessment. Standards such as IEC 62619, NFPA 855 and the Technical Specification provide guidance to mitigate these risks. In this article, we will examine the safety requirements, potential risks and emergency strategies for BESS. Our goal is to lay out a framework that maximizes both the effectiveness and reliability of this technology.

Fire Risks and Precautions

Thermal Leakage and Protection

One of BESS’ biggest safety concerns is the risk of thermal runaway in battery cells. IEC 62619 requires cells to limit combustion propagation in overcharge or short-circuit situations. According to the Technical Specification, while LFP batteries offer the advantage of thermal stability, fire suppression systems compliant with NFPA 855 (e.g. aerosol-based) are mandatory. In addition, UL 9540A tests require measures such as intermediate walls that prevent the spread of fire from one cell to others. This minimizes the risk of fire in a solar power plant.

Electrical Safety

Short Circuit and Over Voltage

Electrical risks are another area to be considered when integrating BESS with the grid. IEC TS 62933-5-1 defines safety mechanisms to protect the system in case of short circuit and overvoltage. According to the Technical Specifications, the Power Conversion System (PCS) should absorb sudden load changes by reacting within 200 ms and should be backed by fuses. For example, a sudden voltage spike in a 10 MW system should be controlled by the BMS activating circuit breakers.

Environmental and Operational Risks

Temperature and Humidity Control

Environmental factors can also affect BESS safety. IEC TS 62933-4-1 addresses the impact of temperature and humidity on battery performance, stipulating a range of 15-25°C with recommended HVAC systems. Excessive temperature can shorten battery life or increase the risk of thermal runaway, while high humidity can lead to corrosion. For example, in a solar power plant, HVAC failure can jeopardize the system’s 80% Depth of Discharge (DoD) performance. These risks should be avoided through regular maintenance and monitoring.

Emergency Strategies

Simulation and Response Plan

Beyond risks, emergency preparedness is also critical. While NFPA 855 provides evacuation and extinguishing protocols for fire scenarios, 3 days theoretical + 3 days practical staff training is also recommended. For example, a thermal runaway in a power plant can be simulated to test the response time of teams; the BMS should disconnect the grid and alert operators when it detects the event. The test methods of IEC 62933-2-1 are used to verify the resilience of the system in such scenarios.

Security and the Future

The safety of BESS is essential to ensure the long-term success of solar power plants. The management of fire, electrical and environmental risks must be ensured by both standards and practical measures. IEC 62619, NFPA 855 and the Technical Specifications prepared by the Solar Employer’s Engineer provide guidance in this process, while regular testing and training keep risks under control.

Recycling and Disposal: Precious metals (lithium, cobalt, nickel) in the battery should be recycled in specialized facilities for recovery.

Environmental Impacts and Sustainability Guidelines according to IEC TS 62933-4-1

The IEC TS 62933-4-1 standard provides some recommendations for reducing the environmental impact of energy storage systems:

Implementation of battery recycling programs,
Use of materials that leave a low carbon footprint,
Prefer battery technologies with high recycling rates.

Technical Design and Performance Criteria for Solar Energy Battery Storage Systems (BESS)

Battery Energy Storage Systems (BESS) in solar power plants play a critical role to ensure the continuity of renewable energy. However, the efficient operation of these systems requires carefully designed engineering and standards-compliant performance criteria. International standards such as IEC 62933-2-1 provide guidance at every stage of BESS, from design to testing. In this article, we will examine the technical design, performance parameters and test methods of a solar integrated BESS. Our aim is to demonstrate how the system maximizes both reliability and efficiency.

Design Requirements

Modular Structure and Components

The BESS design is based on a modular approach. Battery cells (e.g. Lithium Iron Phosphate – LFP), Power Conversion System (PCS), Battery Management System (BMS) and Energy Management System (EMS) work together. The PCS, which complies with the IEC 62477-1 standard, harmonizes the energy flow with the grid, while technical parameters (power plant power, battery capacity, etc.) form the basis of the design. In addition, HVAC systems ensure temperature control and fire safety measures compliant with NFPA 855 (e.g. partition walls to prevent thermal runaway propagation) are a must.

Performance Parameters

Capacity and Efficiency

The performance of a BESS is measured by parameters such as energy capacity, round-trip efficiency and cycle life. According to IEC 62933-2-1, rated energy capacity determines the storage power of the system, while round-trip efficiency above 98% minimizes energy loss. A minimum lifetime of 6000 cycles with 80% Depth of Discharge (DoD) and a maximum self-discharge rate of 4% per month is generally required. This is a reasonable level as it means a stable performance of the solar power plant for 10 years.

Response Time and Charging Speed

It is also critical that the system responds quickly to grid needs. For example, IEC 62933-2-1 requires PCS to respond within 200 milliseconds. The 1C charge/discharge rate specified in the Turkish regulation indicates that the system can fully charge and discharge its entire capacity in one hour. This feature increases the flexibility of solar power plants, especially in applications such as peak shaving or frequency control.

Test Methods

Standards-Based Performance Tests

Extensive testing is in place to verify the performance of the BESS. Clause 6.2.1 of IEC 62933-2-1 defines charge-discharge cycles to measure the actual energy capacity, while 6.2.3 tests round-trip efficiency. For example, tests with 80% DoD check whether the system meets the specified capacity. IEC 62619 tests the safety of battery cells against thermal runaway propagation, while IEC TS 62933-5-1 assesses grid connection compatibility. According to the Technical Specification, these tests must be completed before delivery and the results documented. In short, standards-compliant test procedures are a very important issue.

Practical Implementation and Next Steps

In solar power plants, BESS makes a difference in practical scenarios. For example, 10 MW of excess generation can be stored during the day and transferred to the grid at night, preventing energy waste and balancing demand. According to IEC TS 62933-5-1, the electrical safety and grid integration of the system are also tested, ensuring long-term performance. In the next article, we will discuss the environmental impacts and end-of-life strategies of BESS. Technical design and performance are just the beginning for a sustainable energy future. Of course, they need to be supported by legislation.

Introduction to Battery Energy Storage Systems (BESS) in Solar Power Plants

Solar energy is one of the cornerstones of the renewable energy revolution, but the dependence of its production on weather conditions and time of day poses a serious challenge. Stopping energy production in cloudy weather or at night can put grid stability and energy continuity at risk. This is where Battery Energy Storage Systems (BESS) come into play. BESS stores the excess electricity generated in solar power plants and allows it to be used when needed.

The intermittent nature of solar energy makes energy storage inevitable. For example, excess energy generated during the day is wasted if it is not transferred to the grid, while there is a lack of production at night or during peak demand hours. BESS acts as a bridge to eliminate this imbalance. Equipped with battery technologies such as Lithium Iron Phosphate (LFP), the systems store energy from solar panels and deliver it to the grid or the user when needed. According to technical specifications, a BESS with a capacity of 10 MW and 14 MWh, for example, can significantly increase the efficiency of such a plant. Thus, the reliability and use of renewable energy is expanding.

So, how does a BESS work? The key components of the system include battery cells, Power Conversion System (PCS), Battery Management System (BMS) and Energy Management System (EMS). The battery cells store energy, the PCS converts this energy from alternating current to direct current (or vice versa), the BMS monitors the health and safety of the batteries, and the EMS optimizes the energy flow. According to the IEC 62933-2-1 standard, these components work in a coherent architecture to maximize the performance of the system. For example, 98% round-trip efficiency minimizes energy loss, increasing the efficiency of the BESS.

International standards play a critical role in the design and operation of these systems. IEC 62933-2-1 defines the unit parameters (such as rated energy capacity, response time) and test methods of BESS. For example, specific charge-discharge cycles are applied to measure the actual energy capacity of a system, ensuring compliance with the needs of the solar power plant. Furthermore, IEC TS 62933-4-1 addresses environmental impacts, ensuring the system’s compatibility with the environment. These standards serve as a guide for the integration of BESS with solar energy, improving both safety and efficiency.

The benefits offered by BESS are quite enjoyable. Supporting grid stability, meeting peak demand (peak shaving), providing frequency control and optimizing the use of renewable energy are just a few of them. For example, in a solar power plant, BESS allows excess generation during the day to be used at night, so that energy supply is aligned with demand. For example, a system designed with a 6000 cycle life and 80% Depth of Discharge (DoD) can deliver reliable performance for 10 years. This is a big win both economically and environmentally.

In short, we can define DoD as follows.

In conclusion, BESS is an indispensable solution to unlock the full potential of solar power plants. These systems are shaping the future of renewable energy while increasing grid reliability.
