The future of Wiki-Solar

Wiki-Solar is the world leader in information about the deployment of solar photovoltaic power stations of 4MW_AC and above. Over the 13 years since its creation it has built an unrivalled Database of over 1,000-GW of utility-scale solar plants and projects. Now it is time for the next step ...

From April 2026 Wiki-Solar has become RenewAtlas

A greatly enhanced online platform has been developed by a new team with young innovative management. It covers utility-scale solar, as Wiki-Solar always used to, but is adding hybrid projects, such as solar+storage and solar+wind. Check out this new enhanced resource at www.RenewAtlas.com.

From Philip Wolfe, founder of Wiki-Solar:

I created the Database back in 2012, while writing a book on utility-scale photovoltaics and have kept it going since - mainly out of interest. Recently I have been looking for a new home for Wiki-Solar so I can wind down.

My frank assessment of the status of Wiki-Solar, as I offered it to the new team was:

• The Database currently holds details on over 24,000 solar projects. This has doubled in the last 5 years.
• About ¾ of the projects are active, the rest are in construction or development.
• We collect data from a wide variety of sources, including leading developers and contractors, making Wiki-Solar the most comprehensive and reliable dataset for the sector.
• We have developed sophisticated software to upload and refresh the data. This allows us to maintain the MS Access Database at a commitment around 3-4 person days per week.
• This software has been designed to be suitable also for wind and other energy types, especially where official data sources cover all renewables or energy generally.
• We have several blue chip customers, but have not maximised the commercial potential.
• The website is, frankly, in need of modernisation!

I am delighted that RenewAtlas has been developed to take forward this great resource and am pleased to say that I will still remain involved during the transfer.
