Acquiring Global Horizontal Irradiance solar data is a pivotal moment for those involved in solar energy endeavors. This valuable dataset provides insights into solar radiation levels, enabling precise decision-making in various aspects of solar projects. In the following article, we will guide you through the essential steps to maximize the benefits of your GHI data investment. From site selection to performance modelling, integration with weather data, and ongoing operations, we’ll explore how to leverage this resource effectively in the dynamic world of solar energy.

  • Data Analysis:

The first step after acquiring GHI solar data is to analyse it thoroughly. Start by understanding the format in which the data is provided. GHI data typically includes information about solar radiation levels at various time intervals, often measured in watts per square metre. Familiarise yourself with the data’s time resolution, spatial coverage, and any additional variables such as temperature or cloud cover.

  • Site Selection:

GHI data allows you to identify ideal locations for solar installations. Use Geographic Information System (GIS) software to overlay the GHI data with geographical and topographical information. This will help you pinpoint areas with high solar potential and minimal shading, ensuring that your solar projects are in the most productive spots.

  • System Design and Sizing:

With GHI data in hand, you can accurately design and size your solar energy systems. Knowing the available solar radiation levels throughout the year enables you to optimise the size and orientation of solar panels and select appropriate inverters and energy storage solutions.

  • Performance Modelling:

Develop performance models based on the GHI data to estimate the energy output of your solar installations. These models are crucial for financial projections, allowing you to forecast energy production and revenue, assess project feasibility, and secure financing.

  • Operations and Maintenance:

GHI data isn’t just for project development; it’s also invaluable for operations and maintenance. Regularly monitor the GHI data to track system performance and identify any deviations from expected energy production. This proactive approach helps detect issues early, reducing downtime and maintenance costs.

  1. Integration with Weather Data:

Consider integrating GHI data with weather forecasts to enhance your energy forecasting capabilities. Combining GHI data with cloud cover and temperature information enables more accurate short-term and long-term energy predictions, aiding grid integration and energy trading.

  • Regulatory Compliance:

Stay informed about local regulations and incentives related to solar energy. GHI data can support compliance reporting and help you take advantage of government incentives and renewable energy credits.
