Solar Data Standards for Reliable Project Forecasting

🌤️ CEA Releases New Guidelines for Automatic Weather Stations (AWS) in Solar & Wind Power Projects (July 2025) In a move to enhance forecasting accuracy, RE efficiency, and grid reliability, the Central Electricity Authority (CEA) has issued robust guidelines for AWS deployment across solar and wind plants. 📌 Key Highlights: ✅ Applicability: Mandatory for RE plants ≥50 MW; covers both ISTS and intra-state connected projects. ✅ Site Setup: Defined AWS area (10m x 10m), fencing, grounding, lightning protection, and sensor placement protocols. ✅ Comprehensive Weather Monitoring: Wind plants: Wind speed/direction, air temperature, pressure, humidity Solar plants: GHI, GII, rainfall ✅ High-Precision Sensors: Thermopile pyranometers (GHI/GII) Ultrasonic anemometers Tipping bucket rain gauges ✅ Data Acquisition System (DAS): Real-time sampling, encrypted storage (AES-256) Remote access with strict cyber protocols Data transfer to IMD/NCMRWF every 15 min (1 min during extreme weather) ✅ SCADA & Cyber Security Ready: MODBUS/IEC-104 compatible Firewall, intrusion detection, deep packet inspection ✅ Power Supply: Off-grid ready — solar powered with MF batteries lasting 20 days without recharge ✅ Data Quality Control: Real-time QC, consistency checks, WMO-compliant error detection 🛰️ Why It Matters: This will significantly boost forecasting models, support better RE dispatch, and strengthen India’s digital public infrastructure for energy — especially critical as we scale toward 500+ GW of RE capacity. #CEA #RenewableEnergy #WeatherMonitoring #SolarPower #WindEnergy #AWS #SmartGrid #IMD #Forecasting #CleanEnergy #EnergyTransition #IndiaEnergy

🔍 IEC 61724-1:2021 – Monitoring Solar Performance, the Right Way 🌞📊 📍 Shared as a PV Inspector & lifelong learner in solar QA In the world of #photovoltaics, performance monitoring isn’t optional — it’s essential. Whether you’re #inspecting a utility-scale plant or a 5 MW rooftop system, data quality defines decision-making. That’s where IEC 61724-1:2021 sets the global gold standard. It covers everything from sensor calibration and data recording to bifacial rear-side irradiance, #soiling impact, and PR accuracy — and yes, it's dense. But also powerful. 🔧 As a PV Inspector, here’s what I learned from deep-diving into this standard: ✅ Defines Class A & B #monitoring systems (utility vs. rooftop scale) ✅ Sets strict guidelines for irradiance, temperature, wind, and electrical output measurements ✅ Emphasizes recalibration, #timestamp integrity (NTP/GPS), and sensor alignment ✅ Highlights rear-side #irradiance, bifacial gain, performance ratio correction, and spectral matching ✅ Encourages use of satellite vs. ground data — but with caution and context ✅ Promotes inspection routines: sensor cleaning, shading checks, soiling loss tracking 📚 I believe learning never stops — especially in solar QA and inspection. Every standard is not just a document — it’s an opportunity to grow. 🙌 Hats off to the International Electrotechnical Commission (IEC) for creating such a robust framework. 📖 Reference: IEC 61724-1:2021 – #Photovoltaic System Performance – Part 1: Monitoring Let’s build solar plants that #perform on paper AND in reality.
