PV Field Data Results

Data Columns

• plr_type: Type of RdTools analysis conducted based on available weather data. ‘sensor’: on-site irradiance and temperature sensors used. ‘nsrdb: satellite weather data used. ‘clearsky’: no on-site weather data available. Modeled irradiance and average temperature was used under clear-sky conditions only
• plr_median: Median system degradation rate in %/yr
• plr_confidence_low: 95% confidence interval for PLR, lower value
• plr_confidence_high: 95% confidence interval for PLR, upper value
• length_years_rounded: Length of performance data set in years (may not be the same as the age of the system if we only have access to some of the system data)
• power_dc: Approximate DC nameplate power of the system (grouped by 2MW.)
• pv_climate_zone: Karin PV climate temperature zone, scale of 1-7.
• technology1: PV cell main technology (e.g. c-Si, CdTe, CIGS)
• technology2: PV cell technology sub-category (e.g. PERC, Al-BSF)
• type_mounting: Ground, roof, garage canopy, etc.
• tracking: Boolean, is the system tracking the sun or fixed
