The London Borough of Lewisham is a London borough in south-east London, England and forms a part of Inner London. The borough wascreated in 1965, by the London Government Act 1963, as an amalgamation of the former area of the Metropolitan Borough of Lewisham plus the Metropolitan Borough of Deptford, which had been established in 1900 as divisions of the County of London. Nonetheless, minor boundary modifications have occurred since its creation. One of the most substantial amendments were made in 1996, when the former area of the Royal Docks in Deptford was transferred from the London Borough of Greenwich.
The local authority is Lewisham London Borough Council and it's based in Catford. The borough covers a total area of approximately 13.57 square miles. It's encompassed by the Royal Borough of Greenwich towards the east, the London Borough of Bromley to the south and the London Borough of Southwark towards the west. The River Thames forms a short section of northern boundary with the Isle of Dogs within the London Borough of Tower Hamlets. Deptford Creek, Pool River, River Quaggy and River Ravensbourne pass via the borough.
According to population estimates made in the middle of 2014, Lewisham is a borough with approximately 291933 permanent residents. Around 43 per cent of homes are owner-occupiers. The Prime Meridian passes through Lewisham. Blackheath, Goldsmiths, University of London and Millwall F.C. are positioned inside the borough.

It’s vital to purchase a solar panel system that suits your property. If you’re investing in a solar panel system, it makes the most financial sense to get the biggest one possible. However, whether you can do this or not depends on budget and space.
Here’s an idea of how much roof or ground space you’ll need to install a few different sizes of commercial solar panel system.
Solar panel system size, No. of solar panels, Approximate area required
11kW, 44, 64m²
20kW, 80, 116m²
30kW, 120, 173m²
40kW, 160, 231m²
50kW, 200, 288m²
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.
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
