FREQUENTLY ASKED QUESTIONS

WHAT IS THE DIFFERENCE BETWEEN GHI AND DNI?
GHI measures the total solar radiation received on a horizontal surface, summing both direct and diffuse radiation. It is essential for calculating the total solar potential within a particular area. In contrast, Direct Normal Irradiance (DNI) specifically quantifies solar radiation received from the direction of the sun’s rays. This is measured on a surface that is oriented directly towards the sun at any given point. Understanding the distinction between GHI and DNI is crucial for solar system design. GHI is generally used in configurations where panels can capture both types of radiation. Conversely, DNI is vital for concentrating solar power systems that require direct sunlight for optimal functionality. Thus, both measurements serve unique yet complementary roles in solar energy applications.

HOW DOES GHI AFFECT SOLAR PANEL EFFICIENCY?
GHI significantly influences solar panel efficiency by providing an understanding of how much solar radiation a location receives. High GHI values often correlate with improved energy output, while lower values can indicate potential losses in energy generation. Solar panels are designed to convert sunlight into electricity; therefore, the configuration of the panels must adapt to the characteristic GHI of a site. In effect, ideal placement, angle, and model of solar panels can be adapted based on GHI data to maximize energy collection. Moreover, the fluctuations in local GHI over time can inform maintenance schedules and operational adjustments, ensuring optimal performance throughout the solar energy system’s lifespan.
