PV Slate Questions

See here for answers to the most commonly asked questions about our PV Slate.

Please see also our PV Slate Datasheet or PV Slate Installation Guide to answer many common questions.

 

 

Q. Is the PV Slate an accredited product with the Microgeneration Certification Scheme (MCS)?
A.

Yes, the PV Slate received MCS accreditation in 2018. Contact us to discuss why this might be important for your project.

 

Q. How much energy will one generate?
A.

The amount of electricity the PV Slate will generate will vary depending on location, roof angle and pitch. We are happy to provide you with expected energy production on request.

 

Q. How much does each PV Slate weigh?
A.

Each PV Slate weighs between 3.0-3.9kg depending on model. This means it weighs less than the natural slates it replaces so does not increase loading on the property or require any remedial strengthening, which is good news for listed buildings.

 

Q. Can they be used in conservation areas, national parks and on listed buildings?
A.

PV slate was specifically designed to help people in all restricted planning areas gain planning permission. Check the details with your local planning authority and we’re happy to assist where we can.

 

Q. Is there a minimum or maximum roof angle?
A.

PV Slate can be fitted to pitches typically as low as 22.5 degrees. However, contact us and we will advise on the correct PV Slate product for your roof pitch and location.  

 

Q. What size natural slate sizes can I use PV Slates with?
A.

PV Slate 600x300 is compatible with natural slates of 600x300x6mm (24”x12”).

PV Slate 500x300 is compatible with natural slates of 500x300x6mm (20”x12”).

PV Slate 500x250 is compatible with natural slates of 500x250x6mm (20”x10”).

 

Q. What slates will PV Slates colour match best with?
A.

All blue-grey ranges including Welsh Cwt y Bugail (Not Heather Blue), Cornish Delabole, Northern Spanish, Canadian and Brazilian blue-greys. The darker blue-grey ranges will take time on the roof to bleach down to match the PV Slates.

You are welcome to visit our South Wales factory by appointment to view colour matches.

 

Q. Will PV Slates work with tiles/fibre cement slates?
A.

Contact us to discuss tile/fibre cement slate compatibility.

Q. How do I know how many PV slates I need?
A.

Please send your architect’s drawings to us in an email to info@gb-sol.co.uk and we’ll be happy to calculate how many PV slates your roof can accommodate. If you don’t have these, please provide your roof dimensions and we’ll produce an estimate.

 

Q. How many PV slates fit in a square metre?
A.

PV Slate 600x300: 4.2 per m2

PV Slate 500x300: 5.5 per m2

PV Slate 500x250: 5.0 per m2

As natural slates need to surround the PV slates, please contact us for an accurate number of PV slates your roof can accommodate.

 

Q. Can PV slates be used to cover the roof completely?
A.

As the PV slate resembles the look of whole natural slates and isn’t able to be cut to fit the roof (or at valleys), there needs to be a full border of natural slates around the edges of the roof as well as around any obstructions like roof lights.

 

Q. What size is the PV slate?
A.

 The PV Slate total size and visible size is shown on the technical data sheet (see downloads section).

 

PV Slate has now been extended to a full roof system

 PV Slate is now available edge-to-edge. It is now almost impossible to distinguish GB-Sol's PV Slates from natural slates, as the system has been extended to be able to cover the whole roof.

GB-Sol first full roof PV Slate scheme has now been commissioned at Pilton Methodist Church Hall in Somerset, with the support of local architect Roger Barnes.  140 PV Slates were used, generating 3.85kWp of power and replacing 420 natural slates.  The system works with a Tesla Powerwall installed by our friends Solarsense for a complete solar & battery system.

PV Slate creates stunning roofs that have the look and feel of natural slate combined with the hidden electricity generating power of high efficiency solar cells.  PV Slates can also be fitted right alongside natural slates and come with a 25 year warranty.

Manufactured in Wales, the GB-Sol PV Slates have been designed and independently tested to withstand the extremes of the UK weather.  Popular with UK Local Authority planning departments, churches and listed buildings:  PV Slate is the perfect solution where aesthetics are vitally important.
