We are accredited MCS installers of PV (photovoltaic) Solar Panels.
Solar electricity generates electricity using the photovoltaic effect. This electricity is used to power the lights, TV and other appliances. Any surplus can be fed into the National Grid.
Solar thermal uses the heat from the sun to heat water. This heat is then transferred to the hot water tank and used for baths and showers. It may also be used for underfloor heating.
Choose solar electricity because the financial returns are better!
Now that the government has introduced feed-in tariffs for solar electricity, the life time return on investment on photovoltaic (electricity generating) panels is between 9% - 14%.This is much higher than the investment return on solar hot water systems.
The government is considering bringing in a 'tariff' incentive for solar hot water in 2011. However the details have not been worked out. In particular it is not clear whether the incentive will be 'backdated' to apply to systems installed before 2011.It therefore makes sense to install panels for electricity generation, where the feed-in tariffs have already been announced, effective from 1st April 2010. Solar hot water is a completely different system and can easily be installed at a later date.
Some other differences to note:
Solar PV is a no hassle solution – no need to change your hot water tank Installing solar hot water often requires a complete change of tank, resulting in a perfectly good tank being thrown away needlessly. This is a hassle which doesn't apply to solar electricity.
The energy generated by Solar PV is much easier to measure The energy generated from solar photovoltaic panels is easily measured – and must be measured using a 'Total Generation Meter' for the purposes of working out the feed-in tariff.
In contrast it is much more difficult to know exactly how much energy has been generated by solar hot water panels. All you can do is look at the thermostat in your hot water tank and read the temperatures at the top and bottom of the tank at various points during the day. The problem is that as soon as you let more water in from the mains, the temperature at the bottom of the tank will fall by several degrees, regardless of whether the sun is shining or not. Keeping track of gains from the sun is very difficult.
Solar PV uses the light from the sun rather than the heat A solar PV system will generate a high return on a sunny day, whether that day is in January or in July. It relies on light from the sun, not heat. In fact it will generate energy even on an overcast day.
Solar hot water panels will warm up in winter. However because the surrounding air is so much cooler, the heat will quickly dissipate into the air. Relatively little of it will be transferred to your hot water tank.
About the solar panels we install
Each panel measures 1.65m x 0.995m
The output of each panel is between 220 and 250wp depending on panel used.
3.2 kilowatt system is the average size installed on the roof and this is made up of 14 panels.
The system can be installed on East to West through South facing pitch roofs.
The output is guaranteed for 25 years by the manufacturer.
The panels are covered by product liability insurance.
The systems are mounted on aluminium racks which are in turn mounted on the roofing joists. No tiles or slates are permanently removed for the installation.
The mounting brackets slip underneath the tiles and therefore there is no risk to the integrity or waterproofing of the roof.
It is anticipated that a 3.2kw system could save in the region of 40%-60% of electricity that an average 3 bedroom detached property uses.
All electrical work will be Part P Certified and carried out by a qualified Electrician.
Make money by selling the electricity you generate! The government are paying you simply to put panels on your roof and generate electricity. > learn more
