Screening a site of your own?
Cornwall approves 92% of solar farms. Redline puts that number, and everything else the record holds, against your own boundary: the authority’s actual approval rate and decision times, every designation inside the red line, agricultural grade, 1 m LIDAR earthworks, how contested the grid is, and yield with a P90 — before you spend on a consultant.

What this site sits on
The recorded coordinate falls on land surveyed as Grade 3 agricultural land. The published survey does not split Grade 3 into 3a and 3b, so this alone does not settle whether the land counts as best and most versatile.
REPD gives one representative coordinate per scheme, not the site boundary, so this describes the point on record rather than the whole site — a large site can straddle a designation edge. Boundaries come from planning.data.gov.uk, which publishes for England only.

How big is Trethosa Farm Solar Park?
Trethosa Farm Solar Park has a recorded installed capacity of 4.8 MW. That figure is the capacity registered in REPD, which is the scheme as consented — the metered output of a site can differ.
Who operates Trethosa Farm Solar Park?
REPD records the operator as Trethosa Solar Ltd. Ownership of built renewable assets changes hands regularly and REPD is published quarterly, so treat this as the operator of record rather than confirmation of who owns it today.
When was Trethosa Farm Solar Park approved and built?
The application was submitted on 28 January 2014. Permission was granted on 6 June 2014, 4 months later. The site became operational on 9 October 2015, 16 months after consent.
Source: Renewable Energy Planning Database (REPD), Department for Energy Security and Net Zero, Open Government Licence v3.0, plus planning designation boundaries from planning.data.gov.uk (England only). REPD is published quarterly and covers schemes of roughly 150 kW and above. Capacity is the installed capacity on record, not metered generation. Operator is the operator of record at the last extract, not confirmation of present ownership. Reference 1896.
