EcoSentec provides three types of solar radiation sensors: silicon-cell, thermopile, and photodiode pyranometers. Each type offers unique benefits, catering to different application needs and budgets.

Silicon-cell pyranometers use a silicon photovoltaic cell to measure solar radiation.

• Faster Response Time: Provides real-time measurements with rapid data output.

• Cost-Effective: More affordable, making it ideal for applications with budget constraints.

• Limitations: Silicon cells have a narrower spectral range, resulting in higher measurement errors under cloudy conditions or when the solar spectrum varies.

Thermopile pyranometers use a blackbody thermopile detector that generates a voltage proportional to the incoming solar radiation.

• Broad and Uniform Spectral Response: Measures the full solar spectrum (300 nm – 2800 nm), ensuring accurate data in all atmospheric conditions.

• Superior Accuracy: Provides more precise measurements compared to silicon-cell sensors, especially in cloudy or low-light conditions.

• Durability: Highly stable performance over time, making it suitable for long-term monitoring.

Photodiode pyranometers use semiconductor photodiodes to detect solar radiation by converting light into an electrical current.

• Fast and Reliable: Quick response time with consistent performance.

• Compact and Lightweight: Suitable for portable or space-constrained installations.

• Moderate Accuracy: Offers better performance than silicon-cell models but is less accurate than thermopile sensors.

• Cost-Efficient: Provides a balance between accuracy and affordability.
