Knowledge sharing

This page details how industry participants can notify Wiki-Solar about a number of projects.

To tell us about a single new plant, which we don't show, go here. To update or correct projects that are shown, go here

Providing data for multiple plants

To ensure that our lists of leading companies are consistent and independent, we derive the totals by adding up all the utility-scale solar projects in which they are involved.

Leading utility-scale solar companies

The pages in this section of the website show the few dozen leading players in the global utility-scale solar sector. For those companies(and those that are close to entering the list) Wiki-Solar prepares a spreadsheet in the form shown below, pre-loaded with the projects we know about. These organisationscan then check our data and provide updates and corrections, where required. If you want to know if we have this list for your company, please email us.

If not, notify us of your utility-scale solar projects anyway. You can do this by sending your own list, if you have one; or use the template shown below, which can be downloaded here.


We appreciate that stock-exchange listed companies and others may not want to publicise certain details about some of their projects..Our template therefore has a 'confidentiality' column, where you can indicate any rows where this applies. We will then use this data only to build up the totals for your company rankings. We will not publish details about these projects, nor show them on our maps, except when using information that is publicly available elsewhere.

Images and map links

Where we provide pre-loaded spreadsheets, as mentioned above, we include in columns AA and AB on the right hyperlinks to the project footprints on Google Maps and to a photograph or artist's impression of the project (where available).

Thank you!

It may take a week or two for your new plant to appear on our maps after validation.

Many thanks for helping keep this data as accurate as possible. If you are a participant in the project, it will also help you achieve your rightful place in the company rankings.

The data we need

We would like as much data as you are happy to provide (hence all the columns!), but we're not asking you to do lots of work. The essential data to enable us to list a project is the name, capacity, location and CoD; plus your roles, of course. These are the green-headed columns.

The yellow-headed columns show other useful data, such as geo-coordinates. The orange-headed columns are 'nice to have' data.


In column J you can indicate if any of the projects should not be made public - see more on the left.

Filling in the template

To speed things up, we've included some default fields in row 5. Any answers you put in there will automatically fill out for each project you add (but can be over-ridden if required). Use these, for example, for your usual project roles

Participant roles

If in doubt about what each participant does, see further definitions here.

There is a notes column (R), where you can add any other details.

Site location

You can get latitude and longitude from Google Maps and similar programmes. Simply zoom in on the appropriate area, place the cursor over the centre of the project site and right click. Select 'what's here' and Google Maps will display the latitude and longitude, perhaps up to 6 decimal places - we only need 3 or 4.

Please show latitudes in the Southern hemisphere and longitudes to the West as negative.

Capacity, dates and figures

These need to be entered as purely numerical answers based on the units shown. Dates are in mmm-yyyy format.
