Solar PV – questions & answers

WHY INSTALL PHOTOVOLTAIC (PV) SOLAR PANELS?

Your Solar PV system will generate electricity for you. Your home or business will automatically use your solar electricity before you buy any from the grid.   Example:  Your home has an electrical demand right now of 2.5 kW.  Your PV system, right now, is producing 3 kW.  This means your home is able to run for free using the PV systems output of 3 kW and there is still half a kW spare.   This can be diverted into water tanks to reduce gas / oil bills too.  (Please call for more detailed info about this new and superb system for 2020)

We can install an ‘In roof’ system or an ‘On roof’ system.

We only use ‘A Grade’ Mono-crystalline celled panels which are the most reactive to light.  They will produce electricity for over 25 years.

WHAT DOES IT COST?

PV systems differ in size, specification & design. A domestic system will cost less than a commercial system due to the size.

As a guide, for 2020 a 4.2 kW system will cost approx. £5,200 which includes the full installation, scaffold, demo etc.

We can send a guide line quotation to you but we will need some basic information first. Please send a quick enquiry via the ‘Contact us’ tab on the home page and we will answer any specific questions you may have.

DO WE HAVE ENOUGH SUN IN THE UK TO MAKE OUR PV PANELS WORK?

Yes, surprisingly the UK annually receives 60% of the light falling on the equator. South Wales has an average of around 1100kWh per kW peak installed where panels are optimally positioned. South, South East or South Westerly facing roof tops are ideal for PV in the UK.

We have installed over 400 PV systems (Domestic & Commercial) and have documented proof of how efficient and reliable these systems are in our area. (South Wales) On average OUR PV system installations are performing about 12 to 18% above our predicted annual generation.

DO I NEED PLANNING PERMISSION?

No, PV systems fall under ‘Permitted development rights’ so most domestic PV systems do not require planning permission. Listed buildings may require planning permission but laws are very lenient where PV is involved.

Main stream government relaxed all the bi laws in April 2012 so that we can all enjoy generating our own electricity without nonsense restrictions.

HOW LONG WILL MY PV SYSTEM BE GUARANTEED FOR?

Photo voltaic panels have no moving parts so our quality ‘A Grade’ MCS accredited PV panels are guaranteed for 25 years, but can remain efficient for up to 35 years. The higher the quality of the PV panel, the longer it remains efficient for, and the more electricity it will produce in cloudy or less light conditions. A high quality PV panel is essential for this.

Also all our inverters come with a 10 year straight replacement warranty.
