Energy savings - Compared to a standard 6Kva system

All our figures are calculated based on REAL- LIFE daily usage, taking into account using the appliances & heating in wintertime and summertime. A full energy presentation is available on request.

Based on 10 hours per day for 260 days, 80 days in winter mode and 180 days in summer mode. Each day is a typical usage day. 16 Persons accommodated. £1.70p per litre Diesel / HVO. £60 per H2 Bottle..
Solar panels achieve maximum output in direct sunlight, but they work in normal daylight and cloudy weather too. The amount of power a solar panel or charging kit generates in cloudy weather will be lower compared to direct sunlight. Also the positioning of the cabin will affect the solar charging of the batteries i.e. under trees, etc. This assessment doesn’t take in consideration the usage of the hydraulics. This assessment is guidance only.
