Why car parks are the hottest space in solar power - BBC Newshttps://www.bbc.co.uk/news/business-65626371.ampThere is a huge opportunity to turn more British car parks into solar farms, according to a new report published by the countryside charity CPRE and the UCL Energy Institute.
"We think the total potential in the built environment is about 117GW," says Prof Mark Barrett of UCL. "And of that, 11GW, we think, is car parks."
For context, the UK currently has around 15GW of solar capacity in total and requires 40GW by 2030 in order to meet net zero targets, according to Solar Energy UK.
Prof Barrett notes that the figure of 11GW is conservative and is based on an estimate of 130 sq km of available car parks in the UK - lower than the 200 sq km estimated by estate agents Knight Frank. The CPRE and UCL report also assumed that 50% of each individual car park would be covered by a canopy rather than 100%.

UK chybí do net zero (krom větru) ještě 25GW fotovoltaiky. Z toho 11GW je dosažitelných pokrytím konzervativního odhadu 150km
2 parkovišť z 50% střechou s FV panely

But the steel supports required for many solar canopies do add to the cost. It is often cheaper to simply put solar panels on the roof of large buildings, such as supermarkets. Mr Evans estimates that rooftop solar yields electricity at about 9p per kWh currently, versus 14p or 15p per kWh from panels in car parks.

Ale nyní (dokud jsou volné) je výhodnější panely osadit přímo střechy obchoďáků, jelikož nepotřebují tak komplikovanou ocelovou konstrukci
Nicméně, nějaké solární parkoviště už v UK existují a nyní jedna firma zpracovává nabídku na další 4 x 5MW
