Overton Port Eynon, Swansea – BBC One Show Mother of All Challenges for Sports Relief
Here is a short collection of clips shot for the BBC One show “Mother of all Challenges” for Sports Relief with presenter Alex Jones. It was a very early start and a long hike with heavy equipment through muddy fields, but worth it for the breath taking Welsh cliffs and seascapes!
It was great to see a lot of the clips in the final show, that went out live the same day – here is the programme

“Alex Jones teamed up with four inspirational Mums as they took on five days of gruelling challenges around the UK for Sport Relief. They put their bodies to the test to raise life-changing money and awareness of important issues around maternal health, with the nation following their journey on The One Show. The team braved the cold as they swam across Scotland’s most famous loch, hiked and cycled some of the Lake Districts most famous passes, battled the Porth Yr Ogof cave in the Brecon Beacons and finished with a cross-country run across the hilly Welsh coast. ” – BBC One Show
When a Solar PV Thermographic Survey Can Actually Be Flown
A solar thermographic survey only produces usable evidence when the array is generating properly. IEC TS 62446-3:2017 sets the minimum at 600 W/m² in the plane of the array, and sun elevation, sky stability, wind, wet panels and a curtailed array will each close the window on their own. This post explains why those conditions decide the data, and why a survey flown outside them tends to return a false all-clear rather than an honest result.
Hot Spot, Bypass Diode or PID: Reading Solar Panel Thermal Signatures
A thermal image of a photovoltaic array records surface temperature, and surface temperature is a symptom rather than a diagnosis. This post sets out how the signatures are actually read on an operating array: what a single hot cell suggests, why a uniformly warm third of a module points somewhere entirely different, how potential-induced degradation gives itself away by geometry, and why severity under IEC 62446-3:2017 is framed with caution rather than asserted from one temperature figure.
Following the Water: Gutters, Valleys and Where a Roof Sheds Rain
A roof moves rainwater along a designed path, from slope to valley to gutter to outlet. Autumn is when that path is loaded for the first time in months, and when anything silted, sagging or split begins to show. Almost none of it is visible from ground level. This is what an aerial inspection records about roof drainage, why standing water is such a useful signal, and how observations are marked on the imagery so a contractor can quote from them.
