Evaluating Solar Plant Monitoring for Commercial Solar Plants

Evaluating Solar Plant Monitoring for Commercial Solar Plants

One of our clients installs PV plants and offers solar O&M service. They monitor their growing fleet of small commercial solar plants with the Solar-Log® energy management. They recently conducted an internal company evaluation to confirm that they were on the right course for their investors and the solar business. These are the areas they were evaluating;

  • Overall health of the fleet
  • Ways to predict and avoid long-term losses
  • Ways to improve in-house efficiency

They commissioned the help of the team at Solar Data Systems (SDSI) to help analyze these areas.

Overall Health of the Fleet

The average plant size in this fleet is 100kWp. Our client and their investor were looking for concrete information regarding how well the solar PV plants were performing. Solar Data Systems provided a fleet-wide, current and historical performance analysis on 28 solar plants. These plants are connected to professional Solar-Log® monitoring and additional plants are being added as their fleet grows.

A dedicated solar monitoring expert on our team provided a multi-point check for each plant using Solar-Log® monitoring. They used the advanced analytics from the monitoring system and identified solar plants that had been underperforming either intermittently or consistently. Once the SDSI team identified malfunctioning plants, they calculated the overall kWh losses caused by the performance issues. Next, they separated these losses by the likely factors that caused them. Some issues can be avoided through a service call, but other factors like weather cannot be influenced. From this analysis, the O&M service provider had clear information and a course of action to increase the health of the fleet.  

Financial Impact

The straight-forward ROI portion of the report was of particular interest to the investor. The SDSI team applied the local electricity cost to the kWh lost. The financial impact of plant downtime was clearly visible to the client. In the month of August 2020, the fleet of 28 plants had a loss equivalent to more than $655. An amount which would have been much higher, if they did not have a professional monitoring solution in place.

Avoid Long-term Power Loss

Almost immediately upon evaluation, it was clear that our client had already taken steps to avoid long-term power losses across their fleet by selecting a reliable monitoring solution.

Solar-Log® has an installed fleet of more than 332,000 sites worldwide. Our experience with professional monitoring can easily confirm that a commercial site of 100kW will have performance issues sooner or later. Quick issue detection is the result of using professional and inverter-agnostic monitoring from the start. Quick detection means fewer (or even no) actions need to be taken. This avoids long-term power loss and minimizes high after-sales and service costs. The Solar-Log® sends notifications if plants are underproducing or not communicating with the platform. Reports can be sent out automatically or run on-demand, as needed. Our client immediately knows exactly what is happening on the solar site, good news and bad.

Solar O&M Service Tool

Solar Plant Monitoring is a great tool for O&M service providers, but it is a valuable tool for other stakeholders as well. Monitoring solar sites provides reliable protection against long-term power losses, ensuring a solid rate of return from the solar plant. Professional solar plant monitoring can also provide credible financial guarantees for investors.

The simple action of running this analysis was also eye-opening for our client. As part of the effort to avoid long-term power loss and save additional time and money, they requested that we regularly send the Performance and ROI Analysis. Thus, ensuring that even gradual or small drops in production do not go unchecked.

Improve in-house Efficiency

Solar Data Systems provides automatic solar incentive reporting for this particular client. During the evaluation period we addressed other ways we could help our client to reduce the man-hours needed for monitoring. As a result, they can use the time saved to focus on more profitable and beneficial tasks (like installing more solar!).

Ease O&M Pain Points

SDSI offers professional services to ease the pain points that come with solar plant issues. Reduce back-end costs and headaches on site, and increase efficiency of the O&M process. Our monitoring professionals can pro-actively monitor plant performance. Dedicated experts receive, analyze and remedy configuration & performance errors, as quickly as possible, so our clients don’t have to.
