A kilowatt-hour (unit symbol: kW⋅h or kW h; commonly written as kWh) is a non-SI unit of energy equal to 3.6 megajoules (MJ) in SI units, which is the energy delivered by one kilowatt of power for one hour. Kilowatt-hours are a common billing unit for electrical energy supplied by electric utilities. Metric prefixes are used for multiples and submultiples of the basic unit, the watt-hour (3.6 kJ).

    Jan was rubbish month for solar

    Looks like we were 20% down on solar generation in Jan 2026 compared to last year :( 🌧️🌂 Only made just over quarter of mega-watt hours this month, not much better than December - whereas Jan 2025 was over 320kWh. Was it equally bad in other parts of the UK?
