Solar FAQ's
New to the world of solar heating? take a look at some common questions, and if your question isn't listed please don't hesitate to get in touch.
Does solar heating really work in the UK?
Yes it does in the UK we receive approximately 60% of the solar radiation that falls on southern Spain.
How long does it take to install?
Usually less than a week.
Do I need Planning permission?
In England, solar water heating systems generally don't need planning permission. There are some exceptions to this rule, for example if your property is listed or is in a conservation area. We suggest getting in touch with your local planning office.
Is solar heating technology reliable?
Yes. We only install panels from the leading manufacturers, which are tried and tested and require the minimum of maintenance.
Why should I pick solar?
Solar hot water systems are well tried, tested and are a very reliable technology. Using free energy from the sun, it reduces carbon fuel usage and so the costs to you.
What does it do on cloudy days?
Solar collectors use solar irradiation so gains are made even on cloudy days. Over a third of winter days will produce some usable energy.
How soon does solar make savings?
As soon as it is switched on a solar hot water systems will start saving on fuel bills.
How much energy do you get from solar systems?
Many of the systems we have fitted are producing over 3000 kwh per annum.
Equivalent to running an immersion heater for over 1000 hours.
Do I still need a boiler?
Yes you will still need a boiler for room heating because solar can not produce 100% of your hot water needs all year round.
What size of panels and cylinders are required
Facing due south requires 1 to 1.25Msq of collector panel per person and approximately 60 litres of stored hot water per person in your storage cylinder. The fitting of a 2.5Msq collector and 170-litre twin coil eco cylinder will suit up to 2 persons.
Can we have solar panels without a south-facing roof?
Solar collectors can be fitted as far as due east and west, but you need to increase the amount of solar collector area the further from south you face them.
What type of cylinder do I need?
Single cylinders with twin coils are the most common, as they are cheaper and are easier to install. Having a pair of cylinders and using one as a preheat can make for a more efficient system. Positioning is important a cylinder should be as close as possible to the collectors to reduces pipe runs and heat losses.
How much will it cost?
We can supply a 2.5Msq solar water heating system, fully fitted to a suitable existing cylinder including a check/service after 500 hours of operation from £2,799 Including 5% VAT.
If required a new 170-litre twin coil solar eco cylinder fitted with above offer £449 Including 5% VAT.
