Why use Monitoring Tools?
Residential and commercial installers, and owners
of systems of any size can now benefit from system monitoring and
display tools. These products provide knowledge and control over
energy system generation and demand. Residential and commercial system
owners can monitor their PV installations and see the impact of
changes in consumption as well as actual system impacts such as tree
shading or equipment degradation over time. Residential and commercial
installers can check system performance, diagnose system issues, and
take corrective actions quickly and cost-effectively.
Monitoring and display products help you see the
condition and performance of your residential and commercial energy
system in real-time. Over time your solar energy generation and demand
fluctuates. Periodic meter readings provide only a vague glimpse at
the long-term changes, while telling you nothing about short-term
performance issues. Good monitoring and display tools can help reveal
trends, transient issues, cost savings opportunities, and emerging
issues. Advanced monitoring tools are remotely accessible via the
Internet. They feature real-time graphics, and historical system
performance data. Get the knowledge and control you need to obtain
maximum performance and cost savings over the lifetime of your system.
Monitoring systems typically consist of hardware
that connects to the energy system, and software that collects,
stores, and displays the data. Older systems required proprietary data
acquisition products and dedicated hardware for data storage and
display. Such systems usually entailed substantial training, high
costs, and inflexible features requiring consulting and custom
programming. |

Residential
Solution Fat Spaniel’s Residential Monitoring Service gives the residential
system owner the monitoring and visualization tools to understand their
solar energy system. The residential solution allows you to improve your net
metering results and reduce your electricity bill by managing your energy
use.
The image to the right is a typical simple view showing
real-time and historical data about energy generation, the
building's energy usage, and environmental information. Energy
information can be selected to show daily, weekly, monthly and
yearly comparisons.
Fat Spaniel offers inverter-direct monitoring for most
grid-tie
inverters as well as revenue grade, inverter-independent monitoring that can
be used for power purchase agreements, performance incentives and renewable
energy credit trading. Residential monitoring systems can be used for
systems under 20 kW.
Inverter-direct monitoring meets the California PUC < 10kW EPBB
metering requirement, and is not designed to meet the PUC PBI metering
requirement. SMA and Fronius inverters require optional equipment from the
inverter manufacturer. See information on the table below. Xantrex inverters
do not require extra equipment. Inverter-direct monitoring comes with a
simple web-based view. Detail view and alerts are an extra-cost option.
|
Inverter-independent monitoring includes ANSI standard
revenue-grade meter with 2% accuracy and meets metering and reporting
requirements of California EPBB & PBI programs and of all states requiring
revenue-grade meters. These systems come with simple and detail web-based
views, and alerts for inverter-off condition and communications failures.
Weather data and building load are options that can be added to the
monitoring package. All packages include hardware, 5 years of hosted
monitoring services and 5 years of warranty coverage. Broadband Internet
access is required for standard systems.
Cellular and dialup modems are optional.Residential Solution Features
• View real-time and historical energy production and usage
• Improve net-metering results
• Access your system information anytime, anywhere
• Show off the environmental benefits of your installation
• Automated alerts reduce service calls
