PV Slate Questions

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

 

 

 

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.

Each PV Slate has a power capacity of between 25Wp and 35Wp depending on the size of slate being matched.  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.

We recommend choosing the lightest grey *6mm thick* slates available in the range that you prefer.  All blue-grey ranges including Siga 37, Cupa 12, Welsh Cwt y Bugail (not Heather Blue), Cornish Delabole and La Concha.  Natural slates with the words dark grey or black in their descriptions will contrast quite strongly with PV Slates. 

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 PV Slate is an electrical product, there needs to be a border of two natural slates around the edges of the roof and any roof windows.  We can make passive "infill" PV Slates to complete the surround for a perfect finish and a roof that no one would believe was solar.

 

PV Slate chosen for Barnes Methodist Church

We are now fitting x338 of our largest solar PV Slates to Barnes Methodist Church in west London, discretely generating 12kW of solar power on this wonderful listed building. 

The new roof can be seen from the B349 Station Road side of the church.  The trustees of the church decided to use GB-Sol PV Slates after Richmond Council determined that putting conventional solar panels over the roof of this historic building was not appropriate
