Modern solar work nicely in UK in May-August when wind is weakest due to long hours and cooler weather. However one needs more expensive panels that also work on a cloudy days. Then in UK somebody calculated that a house needs 1MWh battery to last over winter using only solar panels that a typical suburb house can install. In 5-10 years that would cost 40K USD making it rather realistic to have. This ignore availability of industrial-scale wind which is the strongest in winter. |
