Products for Solar Energy - System Design 

Images - Monthly yield calculator

The solar monthly yield calculator tool allows to quickly check the expected electricity generation and their seasonal behavior of different PV system layouts for any location in the world.

Solar report - PV system layout comparison

Seasonal production profiles help to optimize your system layout.

  • Monthly reference yield for 20 different inclinations & orientation
  • Optimize your yield on your consumption

Solar report - PV yield variability

Analyses of availability and variability of radiation or PV-power for any site in the world. Based on the hourly time series since 1986 the radiation climate of your site is analysed. The interannual, seasonal or daily radiation distribution is summarized in intuitive graphics to support your site selection or system management strategy.

Solar history - Raw data

meteoblue offers raw data as hourly, daily or monthly time series or TMY (Typical Meteorological Year) since 1985 with a spatial resolution of 30 km for the following variables: 

  • solar radiation 
  • PV reference yield
  • sunshine 
  • cloud cover 
  • temperature and dew point temperature 

Other variables on demand.
