Roof Mounted Solar Panels

Installing solar roof panels is one of the best investments for increasing the value of a property and reducing energy bills. A solar heating system could provide up to 70% of a homes annual hot water or electricity. The electricity produced by the solar panels can be used anywhere in the house. During the night the panels will not produce any electricity so all electricity will be bought from the grid as normal. During the day however, any unused electricity can be sold back to the national grid. Compare Solar Panel Prices and discover the benefits of isntallation.
Solar roof panels have improved considerably over the last few years making them even more efficient and an attractive green investment for the conscientious family.

Roof Mounted Solar Panels


Roof panels are known for providing solar hot water and it is the most common use of solar technology in the UK. Basically solar roof panels work by converting sunlight into electricity and this can be achieved even on a cloudy day. The panels take over the heating of the hot water in a home during daylight hours. This means there is no electricity or gas used to heat the water during the day. At night time the house reverts to using the conventional hot water boiler system.
The solar panels work by gathering heat during the day which is used to heat a fluid within the panels. This fluid then moves through the pipes to the heat exchanger which in turn is transferred to the water in the hot water cylinder.
Flat plate solar roof panels can also be installed inside the roof. These panels use a special low iron glass formula that increases absorption due to its reduced reflective property. This is achieved because the coated surface is not flat and is made up of thousands of tiny pyramids.

Do Solar Panels work in Cooler Climates


The simple answer is yes, solar roof panels are just as effective in cooler climes and work all the year round. Special solar panels have been developed and manufactured for use in temperate climates such as the UK and other northern European countries. These panels can be mounted on a southerly facing roof or alternatively on a east to west facing roof.

The Cost of Installing Solar Panels


The cost of course depends on the size of the home and the number of solar roof panels installed. For example a 1 -2 person system would average around £3,500 -£6,000 fitted. For a 4 person system the price would be around £7,000 - £9,000. Costs for larger systems with more roof panels and larger water tanks, range between £10,000 - £12,000. The largest domestic systems of 4kw would cost approximately £17,000 - £20,000. Although these costs seem high, solar roof panels are a long term investment and will easily pay for themselves in less than 10 years. Any excess electricity produced can also be sent back to the grid for resale to other homes and businesses. This arrangement will generate an extra 3p for each unit sold to the national grid. Additionally every unit of electricity produced will earn an extra 41.3p. Over a 25 year period this can add up to an additional £1000+ per annum, which is tax free.
British Gas is also now offering to rent the roof of any their customers and pay for the installation of the solar panels. The benefits for the customer include no installation costs and ongoing savings on the annual energy bill. These savings vary of course depending on the size of the property. For example, a roof with 20m2 area would equate to an annual saving of around £122; whereas a roof with 23m2 area would save around £152 on the annual energy bill

  2. Can anyone explain or is it possible for a post about the differences between roof mounted solar panels and solar tiles. I've heard a bit about solar tiles and be interested to find out more and the difference between the two, especially cost and energy produced.

  5. I would agree with you that installing solar roof panels is one of the best investments for increasing the value of a property and reducing energy bills. A home with a fixed electric bill from solar is less expensive to live in, and it would appeal to potential buyers.

  6. Homeowners who have installed solar power, is likely to be affected by moisture damage, cracks in the roof panels and lack of warranty coverage for the roof, because the work is improperly done. A solar cell typically weighs half a ton, and you can not just mount on a standard roof, which is only designed to support a roof covering. If you put a heavy solar up on a roof that does not have the strength to carry the system runs the risk of deflection of the roof and other damage to the structure theorem. photovoltaic company should have both an engineer and construction manager with out looking at the roof to ensure that no damage occurs.

  7. The rafters, tie beams and joists serve to transmit the weight of the roof to the walls of the building. There are a number of structural systems employed to facilitate this, including the use of wall plates set at the top of the wall, hammer beams, which spread the weight down the wall and create an equilibrium between outward and upward thrust, king posts which transfer the weight of the roof ridge, and various types of trusses. Thanks.

  8. My recommendation to anyone thinking of installing solar panels is to check with the Energy Saving Trust to ensure the company who will be carrying out the solar panel installation is competent and accredited. Also avoid companies who employ pushy sales techniques. Good luck!

  9. Solar energy is the best source of power. But it has a few limitation-
    - expensive
    - consumes lots of space
    - useless at night (doesn't produce energy)
    - Pollution can degrade the cells that produce the energy in the panels
    - Clouds also lessen the amount of sun which = less energy produced.
