How to Inspect a Solar Farm FASTER

How to Inspect a Solar Farm FASTER

How to Reduce Your Drone Solar Farm Inspection Time & Costs by 75%

This is the first of several articles posted in a series to help you understand how to successfully inspect a solar farm with a drone and thermal camera. The goal of this specific post is to clarify how to reduce your drone solar inspection and flight time by more than 75%* by adjusting the sidelap (lateral overlap) of your drone flight to 20%.

Time is money. The more time you spend working on something (drone inspection) the more expensive that task becomes. There are also only so many hours in the day. The longer a specific task (drone inspection) takes to complete the more days you will have to spend working on that task before it is successfully completed.

Over the last 12 months Raptor Maps has helped UAV (drone) pilots inspect over 500 PV sites. For each inspection the goal was to;

  • #1 Capture the highest quality data (imagery),
  • #2 Perform the inspection in the least amount of time so the pilot can move on to the next scheduled solar farm inspection that day/week
  • #3 Deliver a final report to the client that includes all identified anomalies with locations and images of each anomaly

Because our focus is high quality data and to cover as much ground in a single flight as possible, we have come to the conclusion that a solar farm inspection should not be performed as a thermal mapping mission.

Why? Because thermal maps (orthomosaics) require extremely large amounts of data to be collected, hundreds of thousands of images in most cases. This type of data takes a very long time to collect and is low quality. Additionally, the software programs used to create thermal maps do not have a 100% success rate. On average the software will fail to produce a usable thermal map 20-30% of the time. Why waste your time and money on something that is not a quality product and may not even result in a successful end result?

To reduce your inspection flight times, and collect the highest quality imagery, you should adjust your sidelap (lateral overlap) to 20% and abandon the idea of creating a thermal map. This will allow you to reduce your drone PV inspection time by 75% and produce higher quality reports and deliverables with both radiometric thermal and high-definition visual spectrum imagery of the solar site inspected.

The goal of every aerial PV system inspection is to identify the condition of the system and potential issues that are currently unknown. You do not need to make a thermal map to correctly identify and accurately localize the PV system anomalies that are affecting performance. Instead of relying on an low quality thermal map to find anomalies, image-based post-processing software solutions like Raptor Maps can be used instead. These software solutions can  process this smaller, faster-to-collect dataset (imagery) and identify, classify, and localize all solar farm anomalies. Additionally this dataset will always create a valuable and usable final deliverable 100% of the time.

By reducing your sidelap (lateral overlap) down to 20% you can increase the amount of PV plant you are able to inspect by 400%. You can now inspect an entire solar farm in 1 day that used to take 4 days. You can now inspect 4 PV systems in 1 day (when they are close to each other) instead of the project taking 4 days. This small adjustment to your solar farm inspection flight plan will greatly increase your ROI.

If you would like to learn more about how to inspect a solar farm in the least amount of time please contact us HERE or email us directly through info@raptormaps.com. We can also help you learn more about our software that converts your inspection imagery into final reports that are accurate and easy to use for asset management and maintenance.

*This number is based on the comparison of 80/20 overlap in your thermal flight plan to the industry standard 85/85 overlap of a thermal mapping flight plan.

Solar Software Industry Leaders Raptor Maps will Support Cypress Creek Renewables’ Self-Operated Drone Inspections

Solar Software Industry Leaders Raptor Maps will Support Cypress Creek Renewables’ Self-Operated Drone Inspections

Raptor Maps, a Boston-based software company focused on helping enterprise solar companies adopt drone technology to reduce asset management costs and increase plant production, is excited to announce that it has reached an agreement with one of the US’ leading solar companies, Cypress Creek Renewables, to support their internal UAS team with data-analytics and reports from PV plant inspections. Raptor Maps software will be used by the Cypress Creek UAS team to automate the processing and generate reports on over 300 drone solar inspections to be performed in 2019.

“We realized early on that a robust Aerial Thermography program was something we wanted to pursue.  We started scanning sites in 2016 and in early 2017, ordering a fleet of drones and staffing a team of electrical engineers and qualified technicians to lead our Reliability Engineering program.  We quickly found that combining technical analysis with boots on the ground resulted in improved facility performance and reduced O&M costs by minimizing truck rolls,” said Kyle Cooper, Vice President of Operations and Maintenance of Cypress Creek Renewables.

Cypress Creek Renewables, one of the largest integrated solar energy companies in the U.S. has developed one of the leading internal UAS programs for the inspection of PV plants, with over 3 GW of self-performed solar drone inspections since inception. The company has worked with Raptor Maps on a proof-of-concept pilot over the last several months. After successful completion of this 150 MW pilot, they decided to roll-out the Raptor Maps solution on all solar inspections in 2019 and the following years.

“We are very excited to work with Raptor Maps to further develop a platform that pushes our industry-leading Aerial Thermography program to the next level.  The Raptor Maps team has developed a solution that has added excellent value to Cypress Creek O&M. This partnership allows our Reliability Engineering team to focus on inspections, repairs, and analysis and leave the heavy lifting of reviewing thousands of images for anomalies to automation without measurable impacts to accuracy.  The partnership will lead to improved report turnaround time, more time devoted to inspections and repairs, and most importantly improved facility performance for our customers,” said Kyle Cooper.

The software platform automates the review of the tens of thousands of infrared (thermal) and high-definition (digital color) images captured during a solar farm inspection, identifying and localizing DC-health and environmental anomalies impacting plant performance. Analytics generated from the inspection are delivered inside the Raptor Maps web-based software platform, with specifics provided on the exact location of each anomaly following internal naming conventions, each anomaly’s affect on plant production, and a prioritization of all issues for streamlined decision making regarding further investigation in the field. Software modifications were made by Raptor Maps with input from the Cypress Creek UAS team to ensure all reporting met the organizations internal requirements. Final inspection results can be downloaded locally as a final report in several formats or can be viewed online by anyone involved with the PV asset.

Raptor Maps has developed  it’s industry-leading data analytics and reporting software platform over the past 3 years. The company analyzed and delivered reports on over 4 GW of solar PV in 2018. Raptor Maps is excited to support the Cypress Creek UAS team with their internal drone operations and share it’s experience with the team to help them reduce costs and increase efficiencies.

10 Most Common PV System Anomalies Detected by Drones (Part B)

10 Most Common PV System Anomalies Detected by Drones (Part B)

 

Solar companies involved in the design, build, management, and/or maintenance of PV systems are increasingly moving to UAS (drones) to replace field work that take large amounts of time and money. Field walks, IV curve tests, voltage checks, and handheld thermal scans of modules are just a few examples of tasks being replaced with drones by O&M teams around the world. Drones set up with both thermal (IR) and high-resolution (RGB) imaging cameras allow for common mislabeled anomalies (ie. soiling) to be properly identified and not mistaken for module hot spots.

 

In this “Part B” post we are going to cover additional PV system anomalies that can be identified during an aerial solar site inspection performed by a drone. If you missed out on reading “Part A” of  10 Most Common PV System Anomalies Detected by Drones click here.

 

Before we get started, it’s important to make sure you’re familiar with the general workings of PV systems. This is a must when it comes to inspecting solar sites effectively with a drone. Here’s a quick breakdown:

Solar sites → A solar site can have hundreds of rows→ Single or multiple strings are within a row→ Strings are made up of modules→ Modules are made up of several photovoltaic cells (Polycrystalline, amorphous, TPV, multi-junction)

 

1. Combiner off-nominal (warm) or offline

Site level issues such as off-nominal or offline combiners pose a serious threat to the efficiency of a PV system. An anomaly of this scale requires immediate maintenance and is always considered an issue of the highest priority. Combiner anomalies are often mistaken for string level issues. However, their identifying quality is when entire rows clustered together present as warm abnormal geometry in your thermal imagery. To determine it is a combiner issue always reference the as-built. Below is an example of a off-nominal or offline combiner.

 

2. Inverter off-nominal (warm) or offline

Inverter anomalies are also a high priority issue that can drastically affect the power production of a solar site. Similar to combiner level issues, inverters present themselves in thermal imagery as multiple rows in a unique geometry that appear warm or offline. Always reference the as-built drawing and site wiring to confirm that it is an inverter issue. Examples of inverter anomalies include:

 

 

3. Discrepancies from as-built – missing modules, incorrect build

Another common anomaly often identified with a drone inspection is discrepancy from the as-built documents, shown through missing modules, or incorrect builds. These differences are often missed from ground level, but easy to identify within an aerial inspection dataset. Before you perform your PV system inspection make sure you have documents such as site information, layout, and as-built diagrams for reference. When entire modules/parts of PV strings are missing, overall DC power production is dramatically affected.

 

4. Weather damage – hail damage, flooding, windstorm, tornado

With little to no protection PV systems are regularly exposed to the elements and extreme weather conditions. Tornadoes, lightning, high-speed winds, hail, and flooding can all cause tremendous damage to solar sites. Large hail can cause cause shattering, while strong winds can uproot and displace modules from their original position. Although it may not be easily identifiable with system monitoring, weather damage can greatly impact PV health/performance and requires immediate attention.

 

5. Delamination and Other Types of Potential Module Anomalies

Delamination and other suspected module defects are commonly found on both new and old sites. Delamination and other module defects can be spotted in either thermal (radiometric) or RGB imagery, depending on the anomaly, and can appear in several forms. They most commonly look similar to:

Opportunities for Drone Inspections in Solar: PV System Commissioning

Opportunities for Drone Inspections in Solar: PV System Commissioning

The renewable energy sector has seen a tremendous amount of growth over the last few years, and PV (solar) has shifted to the forefront of new clean energy development. In fact according to SEIA, Solar has ranked first or second in new electric capacity additions in each of the last 5 years.”  As of 2017, nearly 56 GW of total solar capacity has now been installed in the US. Solar sites are being built at a never before seen pace and scale on rooftops, deserts, northern climates that see snow and below 0ºF temperatures, and other varying locations around the world where solar is a new energy source. 

 

With the massive growth of solar projects in development and being completed around the world, there are several opportunities for solar companies and asset owners to replace traditional, labor-intensive tasks with drones. Drones can provide value across the cradle-to-grave lifespan of a solar asset, from initial planning/design to ongoing annual maintenance. Using drones within the commissioning of a new PV system is a quick and effective method to assess the quality and operational health of a new plant. In this post, we will cover the commissioning process of a solar project, the benefits of using drones during this stage, and how drones specifically are helping teams reduce time in the field and labor costs associated with PV system commissioning.

 

What is commissioning?

Commissioning is the process which ensures that the PV asset owner’s goals and needs have been met and maintained. This can encompass anything from construction deadlines to safety requirements. These elements are assessed through inspections which cover all aspects of the site from installation to closeout. According to SolarPro the following are to be included in the commissioning process:

  • Verify that the installation is complete.
  • Verify that the installation is safe.
  • Verify that the installation is aesthetically acceptable.
  • Verify that all components of the installation are robust and permanent.
  • Document as-built conditions.
  • Verify system performance.
  • Verify proper system operation.
  • Establish performance benchmarks.
  • Complete any required acceptance documentation.
  • Train the system owner on basic system operation.

 

Benefits of Using Drone Inspections for Solar Commissioning

Because the commissioning process for PV systems is comprised of several technical inspections the use of drones has allowed field technicians, asset owners, and commissioning teams to cut time, costs, and manpower involved in PV site commissioning.

Using drones to replace the field walks, visual inspections and handheld thermal inspections saves large amounts of time and enables teams to spend labor hours on other high-skilled tasks. Drone inspections also deliver a more granular level of data to the end user and a more complete picture of the site in both thermal and high-resolution imagery. Top-down and elevated imagery captured with a drone allows for all anomalies to be identified clearly and in a consistent manner.

 

Commissioning for Warranty

The commissioning process also plays a key part in issuing warranty claims. Many contractors, vendors, and service providers are involved in the development and construction of a solar site and many times warranties are provided to support the work done.

Engineering firms, EPCs, and drone inspection service providers are all beginning to use drones at this stage of a project. Every party involved in this stage of a project can leverage drone data and solar software like Raptor Solar to quickly and easily confirm work has been done as planned.

 

Documentation of Site Commissioning with Raptor Maps

One of the most important factors of commissioning is proper documentation. When performing inspections in a site portfolio manner it is important to have understandable and cohesive reporting and documentation for all aspects of the commissioning process. 

Using analytic and reporting software like Raptor Solar allows companies to turn their drone imagery/video into comprehensive analytics and baseline reports on the overall DC health and condition of a site. A report that provides data and supported imagery on every module of a site will enable asset owners and managers to establish a baseline dataset of the site and compare future inspections against this baseline and track the development of the site over time.

 

Conclusion

With the solar industry growing at an unprecedented rate, new ways to implement drones for asset monitoring and inspection are being uncovered. The benefits of using drones for commissioning inspections are endless as they are providing more detailed inspections for warranty claims, installation checks, and verifying power performance.
