Exclusive figures from 20 out of the 22 local authorities in Wales shows the number of solar parks has increased hugely in the last five years.
Powys has the most solar parks at 42 and the county of Pembrokeshire has 13. And, the numbers look set to rise with 55 solar parks currently in the planning process.
The Rhosygilwen estate in Pembrokeshire is home to one of the first solar parks to be built in Wales. It has 10,000 panels which provides enough electricity to power the whole estate and sell back to the national grid.
Despite this, solar parks aren't popular with everyone. On the border between Cardiff and Newport in Michaelston-Y-Fedw, there are plans to built a 110 acre solar park but residents want it kept for agricultural purposes.
In Wales, 62% of renewable generation stems from sources such as wind and solar with a further 25% coming from thermal renewable generation and 13% from hydro generation.
