Solar Irradiance
Solar Irradiance is a way to measure how much sunlight hits a specific area over time. Think of it as measuring the "strength" of available sunlight for solar power generation. When candidates mention this term, they're usually talking about their experience in calculating or working with sunlight measurements to determine the best locations for solar panels or to predict how much energy a solar installation might produce. It's similar to measuring rainfall, but instead of measuring water, we're measuring sunshine. This knowledge is crucial for anyone involved in planning or managing solar energy projects.

Example Interview Questions
Senior Level Questions
Q: How do you account for seasonal variations in solar irradiance when planning large solar installations?
Expected Answer: A strong answer should explain how they consider different seasons, weather patterns, and location-specific factors to ensure accurate year-round energy production estimates. They should mention using historical data and simulation tools.
Q: How do you evaluate the overall feasibility of a solar project site?
Expected Answer: Should discuss combining solar irradiance data with other factors like land costs, grid connection availability, local regulations, and shading analysis to make comprehensive project recommendations.
Mid Level Questions
Q: What tools do you use to measure and analyze solar irradiance?
Expected Answer: Should be familiar with common measurement devices like pyranometers and software tools for solar resource analysis, explaining how these tools help in project planning.
Q: How do you explain solar irradiance calculations to clients?
Expected Answer: Should demonstrate ability to simplify technical concepts into understandable terms and explain how irradiance measurements translate to actual energy production.
Junior Level Questions
Q: What's the difference between direct and diffuse solar irradiance?
Expected Answer: Should be able to explain in simple terms that direct irradiance is sunlight that comes straight from the sun, while diffuse irradiance is scattered sunlight from clouds and atmosphere.
Q: How does weather affect solar irradiance measurements?
Expected Answer: Should understand basic concepts of how clouds, rain, and atmospheric conditions impact the amount of sunlight reaching solar panels.
