The lifetime of a solar panel depends on its quality and age. Generally, the older a solar panel gets, the less efficient it becomes. The majority of modern solar panels come with 20-30 year warranties, which means that they’ll stay at a good efficiency level for at least this long. Some panels can stay efficient for as long as 40 years, while others won’t last this long.
Merton
The London Borough of Merton is a borough in south-west London, England. The borough was formed under the London Government Act 1963 in 1965 by the merger of the Municipal Borough of Mitcham, the Municipal Borough of Wimbledon along with the Merton and Morden Urban District, all formerly within Surrey. The borough derives its name from the historic parish of Merton, which was centred around the area now generally known as South Wimbledon. The local authority is Merton London Borough Council.
Merton covers a total area of roughly 14.52 square miles. Merton is served by a wide array of National Rail stations across the borough, as well as the southern tip of the London Underground's Northern line and the District line on the Wimbledon branch. It's the only London Borough which has tube, rail and tram services.
The key industrial centres in Merton are Mitcham, Morden and Wimbledon, of which Wimbledon is the largest.

The event occurs over a fortnight at the end of June and start of July and it's the largest annual sporting occasion to take place in the United Kingdom, attracting over 200000 guests through the Wimbledon fortnight.
