candi solar optimizes portfolio performance with Solargis Monitor

candi solar partners with businesses to provide zero-risk, end-to-end solar and battery solutions, made possible through flexible financing customized to clients.

Having tripled its installation base in 2022, candi plans to incorporate an additional 1 GWp of generation capacity into its portfolio.

To sustain a viable growth trajectory, candi has turned to Solargis to provide accurate irradiation data that will enable them to meet expected returns on investment across their projects.

The asset management team at candi is responsible for optimizing the performance of their solar assets, ranging in capacity from 20 kWp to up to 4 MWp.

In addition to achieving budgeted revenue targets, the team’s secondary goal is to optimize costs through investment in technology and innovation.

Previously, candi relied solely on on-site pyranometers to measure the solar resource for its operational projects. However, these ground-based measurements can be susceptible to inaccuracies. candi recognized considerable deviations between the measured solar resource data at their 200kWp to 1MW operational projects and their budgeted resource data, which is a key component of their budgeted production and revenues.

This led to two key issues:

Uncertainty around the accuracy of on-site sensors

Concerns surrounding how the operation of those sensors might affect the reliability of production and revenue calculations

Gianni Ruch, Head of Asset Management at candi solar, said: "We were struggling to meet the operational requirements of our project portfolio due to accuracy issues with our sensors."

candi decided to validate their sensors with high-quality satellite data and turned to Solargis to meet this requirement.

Solargis Monitor provided candi with comprehensive high-frequency solar resource data, enabling them to benchmark measurements from their on-site sensors against reliable satellite readings, revealing deviations between sensor readings and actual project performance.

Solargis’ intra-day high-resolution data was used to validate project models and data across candi’s portfolio and highlight potential project underperformance.

Gianni added: "With Solargis’ highly accurate and reliable data, validation of the solar resource can be done easily. We were able to see that our sensors were generating measurements that were roughly 5% lower than the actual output."

Solargis’ highly accurate resource data, delivered through Monitor, helped to create a robust platform for candi to better understand the performance of its projects against expectations.

This enabled the business to:

1. 1. Optimize and manage the technological performance of solar assets to avoid misallocating project losses.
2. Meet contractual requirements around revenue generation and value budgeting.

Irradiation data inputs for candi’s monthly management reporting are now based entirely on data from Solargis instead of on-site irradiation measurements.

Establishing confidence in irradiation data empowers a more thorough scrutiny of other variables, leading to a more comprehensive understanding of project dynamics. This, in turn, fosters investor confidence in the financial model's robustness and reliability.

Chris concluded: “Solargis has helped us create sustainable growth throughout our operations. One of candi’s four values is to keep it simple, and Solargis does just that for us. Solargis is the gold standard for us. It’s true.”
