Smart Sustainability Suite for Solar PV Power Plants
Smart Sustainability Suite
for Solar PV Power Plants
The capacity utilization factor of a solar power system is highly dependent on the seasonal variations and various site-
specific factors like dust accumulation on PV panels, efficiency of critical components, effectiveness of O&M, etc. Thus for
solar power systems, it is vital to comprehensively manage various aspects of plants operations and maintenance for good
availability and yield.
Lack of relevant information at the right time and place
Modern solar power stations are large – stretching over several acres. Multiple such remotely located power plants add to
the complexity of operations. The parameters should reach key personnel at a central head-office to enable them to make
informed decisions ensuring the optimal management of the plant.
Slow response time in information flow
Solar power plants see massive drops in performance on account of lack of infrastructure to detect silent losses and
communicate these to users, seriously affecting O&M and thereby return on investment of these assets. Actionable
information is the key to trouble-free operation avoidance of unforeseen failures and improved performance coupled with
EcoAxis' Internet of Things (IoT) based remote monitoring solution provides a platform for multiple solar PV power plants to
be critically monitored and thus helps achieving maximum utilization of the plants. We have ready solutions for roof-top and
large scale power plants.
This cloud based solution tracks critical parameters of entire power plant operations (such as solar radiation flux, wind
speed, ambient and solar panel temperature, ambient humidity, DC and AC power levels, string voltages and current,
inverter status, status of switchgear etc.), performance (solar panel efficiency, inverter efficiency), and maintenance on a
minute-by-minute basis —or even faster.
The system provides authentic information through interactive dashboards and reports to plant owners, operations and
maintenance managers and personnel and also to top management – Any device, Anytime, Anywhere. The system
integrates easily with smart devices provides SMS and email notification to key personnel for critical plant conditions that
need immediate attention, thus empowering plant users with information to increase overall plant availability and load factor.
Do you face these challenges?
In case of larger MW scale plants, silent losses like failures of few PV strings, shadowing or inverter failures; can go
unnoticed, leading to serious losses in yield.
Continuous monitoring of a solar PV power system not only helps in quantifying the output of the system in different weather
conditions but also helps in identifying any deviation from normal operation and thus react to any creeping problems before
they get out of hand.
EcoAxis' remote monitoring solution provides a decision support system, with continuously monitored data, automated
analytics for enhancing efficacy of operations & maintenance of solar PV power plants of capacities ranging from a few kW
to a few MW. Additionally, EcoAxis solution generates alerts in case of string or inverter failures as well as any deviation of
parameters from defined range. IPPs and O&M contractors, managers with multiple remote solar PV power plants in
different locations can monitor these plants, from one location & also benchmark performance of these plants.

Following are alerts related to string failures:
Ÿ String failure alerts in case any particular string current falls or string become open
Ÿ Earth fault alerts in case of earth faults related to PV strings
Ÿ String temperature fault in case the temperature of any PV cell in the string exceeds a pre-deﬁned threshold
Ÿ Alerts for low PV efﬁciency fore-warning the need of cleaning the arrays
Following alerts related to inverters failures:
Ÿ Inverter room high temperature failure
Ÿ Inverter trip
Ÿ Through use of big data analytics, the system provides a platform to analyze multiple site performance together,
bench-mark sites against each other and instill best practices across the plants.
Ÿ Using role based analytics, the system delivers crisp and actionable information to key stake-holders in
operations, maintenance, top management etc. to facilitate quick readressal of impending issues.
Ÿ Continuous performance evaluation of the solar strings and instant alerts in cases of drop in performance helps
in identifying and optimizing cleaning intervals of the solar panels.
Ÿ Continuous monitoring of string health condition helps identifying and resolving the string failure conditions and
maximizes Plant Load Factor.
Ÿ Instant SMS alerts in case of inverter trip etc. helped identifying and resolving issues quickly, thereby increasing
Ÿ Overall optimized costs of O&M, improved availability, performance, RoI and reduced Total Cost of Ownership
