Solar PV Panels
Do I need planning permission?
Recent changes to planning law mean that a PV system on a domestic dwelling usually counts as ‘permitted development’ and can be installed on a sloping roof without the need for planning permission, as long as the panels project no more than 200mm from the roof surface (our panels will comply with this, as long as your installation is on a sloping roof) we can contact your local authority on your behalf.
If your installation is on a non-residential property, a flat roof or if your property is a flat, listed building or located in a conservation area or World Heritage site you will require listed building consent or planning consent.
How long will a solar system last?
Solar PV systems are built to last a minimum of 25 years: note that the feed in tariff is payable for 25 years, the performance warranty on the panels is 25 years (specifically guaranteeing a minimum of 80% of original performance).The projected yield takes this into account. The roof fixings also need to be made of non corrosive materials.
The system will obviously last better if it is looked after well. We recommend a five yearly maintenance with panel cleaning and inverter inspection. The inverter is guaranteed for 10 years although it is expected to last longer and extended warranties are available at additional cost.
What guarantees do you offer?
All panels are accredited under the Microgeneration Certification Scheme and are guaranteed by the manufacturer to at least 80% performance after 25 years. Inverters are guaranteed for 5 years (an extended warranty is available on the inverter at extra cost).
We give a 5 year workmanship warranty. In addition we guarantee to investigate and rectify any query or complaint about your system in the first 5 years free of charge, with no call out fee.
How does it work?
Huge amounts of solar energy falls every year from the sun to the Earth, we can use this energy to power electrical energy for our Homes and Businesses , The energy falls onto the panels, which creates DC electricity, an inverter then converts this into AC electricity, which is then used to run your household or business needs.
How much will it cost?
The size of the installation will of course depend on the size of your roof space available. For example 8sqm of roof space can house a 1kw system which as a guide costs £5,000 to £7,000 or a 4kw system which would cost approx £13,000 to £16,000.
How much energy does the average home need?
This depends on you the consumer, obviously the less you waste the less you need. To assess your current needs add up your units consumed on your last 4 electricity bills, or contact your supplier and ask them what is your average electrical consumption is per annum. This is by far the best way to size a system rather than individual use. An average size 3 bed roomed semi detached house can produce 30-50% of its electrical needs using a 2kw system.
Do I need constant sunshine for my PV system to work?
Your PV system does not need direct sunlight for it to work, even on cloudy days your PV system will still produce electricity.
What if it is not producing enough electricity for my needs?
In this case the system will allow energy to come into your home from the national grid. This will be necessary on winter days and of course night time when your PV system turns itself off.
What if the system is producing more electricity than my needs?
In this case the system will export your additional electricity back into the national grid and of course you will be paid for it.
when an Export meter is noy uses it is assumed 50% of your generated electricity is exported back to the grid.
Will I need scaffolding?
Yes, In most cases scaffolding is needed. LC ENERGY SOLUTIONS LTD would survey the site and erect scaffolding if needed.
Will the panels damage my roof?
No, we use a specialist bracket wich slides under the tiles and secures direct to your rafters.
