Showing what's out there

We publish details of projects, both operating and in development, on maps.

We have two types of map. One shows each known project with a place-marker - click on example above or here.

For stations with a known site plan, we show maps of the plant footprints - click on example below or here.

Analysing the results

We process the data in our extensive database to analyse the key participants in the industry both:

We also analyse the key performance and design characteristics of projects to derive average and best practice benchmarks, both worldwide and by region, for parameters such as:

  • Performance ratio
  • Annual output MWh per MWp
  • Site area per MWp
  • Carbon savings
  • Project costs and financing ratios

The world's most comprehensive database

All these outputs are based on our database of over 2,000 solar power generating stations worldwide, including both operating plant and projects in development.

Our info enhances your business

We make Wiki-Solar's unique information resource available to industry participants and watchers in other ways, too:

  • Major periodic reports on key markets or sectors as detailed here
  • Market overviews on demand.
  • A networking service to identify partners in specified regions/sectors.
  • Specific consultancy through our parent company WolfeWare.

What makes it a Wiki?

Though we research much of the data from published sources, a lot comes from you.

Industry participants update or correct data on plants shown, and add new ones.
