The deployment of batteries alongside solar panels will add to the overall cost of the energy system, a leading UK academic has claimed. Storage will enable many households and businesses with solar panels to go off-grid, and in doing so detract from a naturally complimentary relationship between wind and solar generation. “When you combine wind and solar, the resulting storage challenge is a lot less than it is if we were to do it for each of the two on their own,” said Keith Maclean, chair of the UK Energy Research Centre (UKERC). Outlining the findings of energy system modelling conducted by UKERC in conjunction with Sheffield University, he explained: “There’s a very strong anti-correlation between when you need to store solar and when you need to store wind, so they’re acting in that sense in a complimentary manner.
