Data Automation tool for Solar assets

As industries are shifting towards data-driven decisions, It becomes critical to have good quality data to ensure analysis is correct and actionable.

Data not only helps you understand how your solar plant is performing in general  but to compare and analyze how different sections of the plant are performing in comparison to each other using performance indicators like PR, SY, soiling, degradation, etc. For example, data can tell you precisely if a panel is degrading faster than the other panel installed at the same site due to a shadow from the nearby tree. Data can derive intelligence for multiple stakeholders: Sales, engineering, procurement, management and investors. Data intelligence can streamline and give a new way to any solar asset owner to function and manage their company. 

Generally, a MW size of plant produces 100,000 data points in a month. However, as reported by our customers in multiple geographies, 16-20% data points are usually missing in this data due to network or connection failure and/or faulty readings by the data loggers. Because of the huge quantity of data produced otherwise, missing data is usually ignored (an easy way out), thereby creating a void that leads to incorrect conclusions. 

For example, missing data during the sunshine hours can effectively lead to low PR value in days of high energy production, or measurements during night time hours can give a high CUF value which is misleading. 

Also, it is quite common to receive outliers/ bad quality measurements from data loggers, pyranometers due to soiling, bad weather conditions, calibration issues, etc. Generally, as a part of data cleaning, this data is removed from the dataset leading to data loss. 

SmartHelio’s Data Automation Tool aims to provide clean and sanitize data in a single click. 

Our Data Automation tool is designed to clean and sanitize in a way to first remove bad measurements from the dataset and clean the dataset. It later predicts the missing data points with 99% accuracy using Machine Learning algorithms and provides sanitized data. All you need to do is connect your plant via API or upload your data to the tool and click “Submit”. You can simply download sanitized data and use it for your internal analysis.

SmartHelio all set for the Y Combinator Demo Day

SmartHelio all set for the Y Combinator Demo Day

SmartHelio pitching at Y Combinator Demo Day

It was a proud moment for the team when SmartHelio was selected for the Y Combinator startup program W22 batch.  In a few days, on March 29th and 30th, 2022, SmartHelio will be pitching its solution to a league of world-class investors during Y Combinator’s Demo Day.The most awaited event for the startup community all over the world.  The event will feature founders from 43 countries among the 375 startups selected for this batch. 

With the rising concerns of climate change, innovative cleantech solutions are emerging rapidly across the globe. This growth is supported by investors who have invested $775 Bn in cleantech startups in 2021 and it is growing at 27% YoY. It is not only critical to replace fossil fuels but it is also important to make the current and future cleantech infrastructures truly sustainable. 

What does SmartHelio do?

SmartHelio is software that helps solar utilities automatically predict and prevent downtime disruptions, to increase their annual revenue by $10k per MW/ year from their solar plants.

What problem are they solving?

When a solar plant starts underperforming or shuts down suddenly, it directly affects the revenue of solar companies and operational expense increases. The main reason is the inability to automatically identify the reasons. This loss in revenue combined with increased operational expenditure amounts to a $15 Bn/year (and increasing) loss to the industry.

What is SmartHelio’s USP?

Minimize downtime and fix problems with click of a button. Their software reads the live data coming from solar plants, identifies why the plant is under-performing and prescribes actions to the companies with recommended timelines of action. This automation reduces manual interventions in maintaining the solar plants by 80%. If the plant’s data is not accurate, they also offer them their smart sensor IoT device.

Who are their customers?

Solar Developers, often called IPPs – Independent Power Producers (roof-tops and utility).

How did they get here?

The company was the brainchild of Govinda Upadhayay, CEO and Founder of SmartHelio, who is a serial entrepreneur listed in Forbes 30under30 for his work in the clean energy domain. He did his research in climate modeling from a top European tech university, EPFL, Lausanne. Govinda realised that the reactive maintenance of solar plants is affecting the health and its end-of-life. He started his research on designing an intelligent monitoring system that could keep a check on solar assets’ health. 

How has their journey been?

In just two years, SmartHelio bagged 15 international awards for its innovative solution and was selected by 8 prestigious acceleration programs. Recently, SmartHelio won the MassChallenge competition and was selected by the AWS Clean Energy Acceleration program. This year SmartHelio was also awarded the B Corporation Certification for meeting the highest social and environmental standards

Dynamic Cleaning Schedule: A data driven cleaning approach

Book AMA session

One of the major roadblocks for obtaining maximum performance of a PV system is “Panel Soiling” caused due environmental and natural factors. Predominantly, deposition of dust, bird droppings, industrial dust, dust storm, snow etc. Such soiling causes reflection, absorption and partial scattering of irradiance which leads to reduced amount of energy that reaches the PV cell. This in turn,

  • Reduces the Energy Yield/Performance Ratio
  •  Increase in O&M cost
  •  Induces more uncertainty in the solar power forecast
  •  Decrease in share of PV energy in the market

The estimated annual losses due to soiling ranges between ~2% and ~6% depending on the geographical location of the PV system. Therefore, an adequate methodology to mitigate soiling losses has become the need of the hour. Unlike other PV system losses, soiling is reversible i.e soiling can be mechanically removed from the surfaces of the solar panels either through natural means such as rain, wind or artificial means such as manual cleaning, semi-automated or fully automated robotic cleaning.

        The most common anti-soiling technique adopted is the manual wet-cleaning of the entire plant as per fixed schedule. Globally, there has been a visible shift towards robotic cleaning adoption. However, the wide-area spread of the solar plants creates operational challenges for the solar asset managers. In most cases, the soil disposition across the plant is non-uniform and dynamic in nature. Moreover, meteorological events (like rainfall, snow, dust storm, etc.) play a vital role in the overall deposition of soil; hence, these factors should also be considered in the cleaning schedule. A fixed cleaning schedule that normally does not cover these factors, leads to inefficient cleaning and eventually leads to significant loss of energy production and resources (time, water, and labor).

Smarthelio’s Dynamic Cleaning Scheduler takes into consideration soiling trends, meteorological events, cleaning cost and electricity cost and follows an Al-based optimization process to generate a dynamic cleaning schedule and track the cleaning effectiveness for different sections of the plant.

SmartHelio’s HelioCloud GHI Forecast service predicts solar irradiation for any location in the world.

GHI forecasting now includes micro-climatic factors

Book AMA session

Predict solar irradiance with 98% accuracy for any plant across the globe.

SmartHelio’s HelioCloud GHI Forecast service is aimed to assist asset managers, banks and the like to obtain accurate predictions of global horizontal irradiance in any location in the world. 

Global Horizontal Irradiance (GHI), the electromagnetic spectrum obtained from the sun is the direct form of abundant energy resource that fuels many processes on the Earth. Although the sun emits a nearly constant amount of radiation (solar constant = 1361.1 W m-2), we experience considerable temporal and spatial variation in the solar radiation received on the Earth’s surface. Because of this, it becomes important to have a reasonably accurate knowledge on the availability and variability of GHI. 

Today, solar irradiance forecasting receives unprecedented attention from various scientific communities. This is because of the importance of forecasting the variability of solar power for their grid integration, which constitutes a major challenge to a successful transformation of the conventional fossil fuel-based energy sector into a 100% renewable one. 

It turns out, however, that current solutions lack localization of the forecasts. Additionally, such solutions do not also discuss the potential changes in GHI under the umbrella of climate change. But long-term radiation magnitudes recorded over different places proves that GHI undergoes substantial multi-decadal variations, which should be considered in solar resource assessments.

SmartHelio’s HelioCloud GHI Forecast service predicts solar irradiation for any location in the world. To this end, it employs cutting-edge machine learning algorithms along with custom functions to generate insights from historical data that help reduce uncertainty in estimating global horizontal irradiance. 

Furthermore, our algorithms take into account key influencing factors such as:

  • The microclimate of the location (surface roughness, NDVI, aerosol, etc.),
  • Global climatic phenomena (ENSO, NAO, etc.), 
  • Climate change (IPCC RCP Scenarios), and
  • Human factors such as pollution, urbanisation, etc. 

This helps us to achieve long-term forecasting accuracy up to 98%.

We believe that with HelioCloud GHI forecast, solar irradiation forecasting can be reinterpreted from a strenuous task into an effortless and user friendly process whose accuracy can be estimated with greater confidence.

Real-time PV Panel analytics

Enhance your inverter & string-level data insights for solar asset management with real-time PV panel analytics.


You might have seen data at a panel-level in real-time, but have you seen panel-level analytics in real-time

As solar companies are expanding their portfolio, there is a pressing need for module-level data for better management of solar PV systems. In such a scenario, only inverter-level data and string-level data is not sufficient for deep data analytics. You need granular level data that can help you diagnose and predict faults in real-time. Our real-time panel level analytics eliminates the need for manual intervention and adds unforeseen value to drone and equipment surveys. Now companies can diagnose and predict the fault at the initial stage of module underperformance. Thus, saving money, time and energy.

Over the past 2 years, our panel-level analytics has helped solar companies to identify and predict PID losses, module degradation, module mismatch, module tilt issues, cell cracks, and many more. Here are a few important use cases, based on our IoT device, that helped our client save more than 30% on O&M expenses and 8% higher energy production. 

  1. Missing inverter data: Using AI and ML algorithms we predict missing inverter data with 99% accuracy. 
  2. Pyranometer data accuracy: Validates the accuracy of pyranometer data. 
  3. PV module degradation rate: Use our root cause analysis to identify, predict and compare faults like cell cracks, soiling pattern, wire losses, hot spots, connector faults etc. 
  4. Compare different PV modules: Compare the performance of different module manufacturers and performance of the modules in different geographies.

Our newly launched PV Panel analytics tool focuses on IoT technology and ML algorithms. We use this technology to provide module-level insights in real-time on any type of solar module. Companies can further enhance their R&D or analytics effort using our module-level raw data,” Sourabh Maladharee, Product Development Head.
