Coming for SPI:  Global Statistics Tables for Fleet Management

fleetZD.jpg

DECK Monitoring is preparing to release a significant new upgrade to our online Admin Panel interface in time for SPI 13 in Chicago (Oct 22-24). 

This upgrade consists of 3 new page views that feature Fleet Management Tables. Fleet Management Tables are statistics tables showing data from all systems in your portfolio.

In addition to offering new helpful overviews of your portfolio, Fleet Management Tables also have the virtue of allowing users to search, sort, and group systems with matching "tag" labels. This makes it easier for you to directly compare systems with matching age, location, hardware, or your own custom tags. This feature was requested by many of our bigger customers to make it easier to manage a large portfolio of systems.

Like all upgrades to the DECK software application, Fleet Management Tables will be available to all existing users at no additional charge. Registered Admin Panel users will receive an email notification when the new feature is available in your Admin Panel. 

For more detailed information about new Fleet Management Tables, check out our online User Guide here.

Let the solar monitoring experts at DECK help you plan and manage your multi-MW PV project. Our software gives you a solar-specific data visualization interface for your project, providing quick and easy insights into performance across your array. DECK also offers a full suite of products and services for large systems, including battery back-up, PI integration, and controls options including a fully integrated SCADA platform.

You can use DECK Monitoring for a cost-effective added software layer on larger jobs. You will save time and money with our user-friendly software features for analytics, customizable reports, and fully automated alarms. Our unique Relative Performance Analytics alarm is ideal to track performance across large arrays because this metric filters out unwanted "noise" due to varying sunlight conditions.

DECK also offers a cost-saving monitoring alternative for smaller big jobs. Our scalable solution can extend to complete integration for SCADA, battery back-up systems, and more. We can enable you to automatically sync reporting data from your DECK system to your working Excel spreadsheets. We can even integrate the DECK platform with your PI System software.

DECK can provide complete turn-key monitoring solutions for a fraction of your overall project cost. DECK can also integrate with most existing inverter, meter, and gateway devices you may already have spec'ed for your project... our software is compatible with most major brands in the North American marketplace.

Use Relative Performance Analytics for an Automated Pyranometer Accuracy Alarm

RPA-satZD2.jpg

Pyranometers (or other irradiance sensors) are a critical piece of hardware in your PV monitoring package. Irradiance sensors help you see through the "noise" of varying sunlight availability to see a valid performance indicator in all weather conditions. 

Unfortunately, no irradiance sensor will remain accurate for the lifetime of your solar project. Manufacturers for irradiance sensors emphasize the need to monitor sensor performance as the device ages. 

For those who insist on accurate on-site irradiance data, DECK offers this unique approach to create an automated alarm for your irradiance sensor accuracy:

Step One:  purchase our cost-effective satellite irradiance service SolarAnywhere SystemCheck. This service provides accurate irradiation data localized to your project location. 

Step Two: using the new Relative Performance Analytic alarm in your DECK Admin Panel, set up an alarm to monitor the delta between your satellite irradiance value and your on-site irradiance value.

There are many reasons why these two data points may not be identical:  for example, the satellite irradiance value is a global irradiance measurement, whereas your on-site irradiance value may be plane-of-array. 

But any such difference between these data points will not impact the accuracy of your Relative Performance alarm!

The Relative Performance alarm looks at the delta between these two data points over time, comparing recent performance against historical norms. Since the satellite irradiance value does not show deteriorating accuracy over time, this alarm is ideal to reveal diminishing accuracy in your on-site sensor. This alarm can alert you when your on-site sensor may require cleaning or, ultimately, replacement.
