Barnes is a district in the London Borough of Richmond upon Thames. It's inside the north east of the borough and is positioned 9.3 km west south west of Charing Cross.
Barnes has lots of eighteenth centu and 19th century buildings in the streets near Barnes Pond, which make up Barnes Village conservation area exactly where a lot of the mid-19th century buildings are placed. Around the east riverside, there is the WWT London Wetland Centre which adjoins numerous fields for three primary national team sports.
The town used to be part of Surrey, and it appears within the Domesday book as ‘Berne’. Barnes’ village church was constructed between 1100 and 1150 and named the Chapel of St Mary’s. It was extended in the early 13th century, and was added to again in 1786. A huge fire destroyed components of the extensions to the chapel in 1978, so restoration work was done in 1984.
Barnes includes a lot of sporting history spanning decades. In football, a High Master of St Paul’s School, Richard Mulcaster, is recognised with turning mob football into a refereed team sport. The school sits on Lonsdale Road, but in the time of Mulcaster it was located in St Paul’s Cathedral. The town includes a non-league football club known as Stonewall FC, who play at Barn Elms Playing Fields.
Barnes Rugby Club is believed to be the oldest club in the world in any football code. They play next to the WWT London Wetlands Centre. The town is also known for rowing; the loop of the Thames surrounding Barnes is a part of the Championship Course made use of for the Oxford and Cambridge Boat Race.

Solar panels are made up of photovoltaic (PV) cells. These cells are made from silicon semiconductors, which absorb sunlight and convert it into electricity.
There are three main types of PV cell: monocrystalline solar cells, polycrystalline solar cells, and thin film solar cells. Monocrystalline cells are usually the most efficient and expensive, and thin film solar cells are the cheapest and least efficient. These are all made from silicone, but are manufactured in different ways.
Solar energy comes from the sun. Solar panels absorb sunlight, and convert it into electricity. This can be used to power heating systems, lighting and appliances. You can also get solar thermal systems, which use solar energy to warm hot water.
Solar energy is a type of renewable energy, because sunlight is considered to be in unlimited supply.
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.
How much energy a solar panel produces depends on its manufacturer and exposure to the sun. A good-quality solar panel typically has a power output of about 300 watts per hour, but this can vary from about 240 to 360 watts. How much energy your solar panel will produce per day depends on how many hours of unshaded daylight it’s exposed to.
Here’s an idea of how much energy you could expect a large commercial solar panel installation to produce in a year.
Solar panel system size, No. of solar panels, Annual electricity output
11kW, 44, 9,350kW
20kW, 80, 17,000kW
30kW, 120, 25,500kW
40kW, 160, 34,000kW
50kW, 200, 42,500kW
