Off-grid static caravan / park home Oxfordshire

We were approached by Philip Howells of Oxfordshire to power up his static caravan as the grid connection quote was £13,000. Off-grid installer managed to design and install a system costing less than £10,000. The off-grid solar system will power lights, TV’s, computers, fridge, freezer, radio, washing machine, dishwasher, tumble dryer, CCTV, outdoor lighting and outdoor shed and all gardening electrical appliances. 

Philip had prepared the ground where the solar panels were going to be located. He used a heavy duty weed membrane and very neatly pegged it into the ground. This will help prevent weeds from growing in-front on the solar panels and shading them. The solar panels were ground mounted in plastic buckets as there was not enough space on the caravan roof for them to go. This also enabled us to get the solar panels perfectly facing south. Philip had also pre-installed a 10mm 3-core armoured cable going between the solar panels and concrete shed. This armoured cable was used so that it could be buried in the ground to hide it and correctly protected by the armoured sheathing (see photos and videos).
