Lewisham

The London Borough of Lewisham is a London borough in south-east London, England and forms a part of Inner London. The borough wasformed in 1965, by the London Government Act 1963, as an amalgamation of the former location of the Metropolitan Borough of Lewisham as well as the Metropolitan Borough of Deptford, which had been created in 1900 as divisions of the County of London. Nonetheless, minor boundary changes have occurred since its creation. The most significant amendments were made in 1996, when the previous part of the Royal Docks in Deptford was transferred from the London Borough of Greenwich.

The local authority is Lewisham London Borough Council and it is based in Catford. The borough covers a total area of roughly 13.57 square miles. It is encompassed by the Royal Borough of Greenwich to the east, the London Borough of Bromley towards the south as well as the London Borough of Southwark to the west. The River Thames forms a short section of northern boundary together with the Isle of Dogs inside the London Borough of Tower Hamlets. Deptford Creek, Pool River, River Quaggy and River Ravensbourne pass by way of the borough.

As outlined by population estimates produced during 2014, Lewisham is a borough with roughly 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 situated inside the borough.

FAQs

How many solar thermal panels do I need?
Generally, the amount of solar thermal panels you need depends on the number of people living in your home. Experts say that as a rule of thumb you’ll need 1m2 of solar panels for each adult living in your home. So if you live in a 4-person household, you can expect an MCS-registered installer to recommend you a 4m2 system. However, if you have any obstructions near your home that could increase shade on your panels, you might be encouraged to go up to nearer 2m2 per person. You want to make sure that your panels can produce enough hot water for your home as you’ll rely less on your back-up form of heating, which might be a gas boiler or electric immersion heater. Maximise the free energy from the sun and you could save up to £60 per year if you have a gas boiler, £70 if you have an immersion heater or £100 if you have an LPG boiler. Of course, you’ll also need to make sure you’ve got enough roof space for the amount of solar thermal panels that you want, but your installer will be able to advise you on the best course of action.
How to install solar thermal panels?
We always recommend that you ask an MCS-registered company to install your solar thermal panels so you can take advantage of the RHI and any other schemes that may come up in the future. However, if you’re sure you want to do it yourself or you just want a rundown of what the installers will do, here are the general steps on how to install solar thermal panels:
  1. After the installer’s measured up, given you an estimated output and recommended some systems for you, they’ll arrange date to come to your home to install the solar thermal panels. They’ll also let you know if any scaffolding will be required.
  2. Next, they will start to fit the panels, or collectors, to your roof. Stainless steel brackets will be provided with the system and they will remove your roof tiles or slates to attach the brackets to the rafters. They’ll then replace the tiles and add waterproof flashing to ensure you don’t get any roof leaks, and add the frame.
  3. If you’ve chosen evacuated tube solar thermal panels, the installer will bolt the heat transfer unit to the top of the frame but not install the tubes until nearer the end. This is because the tubes start to transfer heat to the exchanger immediately, and when everything is unconnected this could damage the unit.
  4. If you don’t need a new boiler with your installation, a new dual coil water cylinder, pump and system control system will be fitted. It’s best in a loft or upper floor of your home.
  5. A new thermal store or hot water tank that will store the heat provided by the solar system is much larger than a standard tank but it may fit in the spot of your old one. The installer will ensure that it’s connected to the mains cold water, your other heating source (such as a gas boiler or biomass boiler), immersion heater, temperature sensors and the solar collectors themselves.
  6. Next they will install the pumping station, usually near the water tank. The expansion tank will be installed on the solar thermal loop, which is usually nearby. Its job is to prevent pressure changes that could damage the system.
  7. You’ll get a heat generation meter which must be MCS-certified if you want to take advantage of the RHI, and any control equipment that comes with the system will be installed.
  8. The installers will then bring the system to pressure by pumping the heat transfer liquid into the system up to a pressure of around 2 bar.
  9. Finally, your MCS-registered installer will register your solar thermal system so you can apply for RHI payments of up to £525 per year.
  10. So that’s the process of installing solar thermal panels. Remember – it's always best to use a professional to install any kind of renewable technology.
Who makes solar thermal panels?

There are a few trusted companies in the UK that make solar panels. While there are other solar thermal panels out there that are made by Chinese and American companies, we’ll focus on the brands with a longstanding presence in the UK since these are the panels MCS-registered solar companies are likely to recommend to you.

Viessmann, Worcester Bosch, Solar UK and Dimplex make some of the best solar thermal panels in the UK. Dimplex and Viessmann offer both flat plate and evacuated tube solar panels, while Solar UK only offers evacuated tubes. Worcester Bosch’s Greenskies range are all flat plate collectors. Viessmann’s panels come with a 5-year warranty, while Worcester Bosch and Dimplex offer extensive 10-year warranties. However, Solar UK offer a comprehensive 25-year warranty and guarantee that the panels will deliver the same level of performance for 25 years!

We’d recommend choosing evacuated tube solar thermal panels because they are the most efficient. While there won’t be much difference between evacuated tubes and flat plates in the summer, in the winter evacuated tubes are much better at taking heat from the sun than flat plates. Since our winters are long and cold with few daylight hours, we think it makes sense to go with evacuated tubes. However, if your priority is looks over maximising efficiency, you might want to choose flat plate collectors since they sit flat on the roof and look more like solar PV panels, whereas the evacuated tubes will stick out.

Can I install solar thermal panels myself?
In theory, you can install solar thermal panels yourself. But it’s best to leave it to professionals. We’ll explain why here. Solar thermal panels work in a similar way to solar PV panels. They use collectors, in the form of evacuated tubes or flat plate collectors, to collect heat from the sun and use it to heat up water that’s stored in a hot water cylinder. You can use a boiler or immersion heater as a back-up to heat the water further so it’s at the temperature you want. So should you install a solar thermal system yourself? It certainly seems tempting since you can buy full solar thermal DIY kits with everything you need for £1,500 to £2,000. To have a solar hot water system installed by a professional, you’re looking at between £5,000 and £6,000, so it looks like there’s a significant saving to be made. However, if you want to take advantage of the Renewable Heat Incentive (RHI) payments, which is a Government scheme where you’re paid for using a renewable energy source to heat your home and/or its hot water, you can’t install it yourself. You need to engage a Microgeneration Certification Scheme-registered installer who can issue you with a certificate to say that the solar thermal panels have been installed correctly. For a 4m2 system that serves a 4-person household, the payments could be up to £375 per year. That means you could pay your system off within 14 years, and that’s not taking into account any of the savings you’ll make on your energy bills. So, while you can install solar thermal panels yourself, it’s much better in the long term to have them installed by an MCS-registered company.
