We recommend choosing the lightest grey *6mm thick* slates available in the range that you prefer. The best matches we have seen to date are with the Cupa 12, Siga 37, Siga 39, Gallegas 37 & Gallegas 39, and the Cupa H3. Other blue-grey slates including Welsh Cwt y Bugail (not Heather Blue), Cornish Delabole and La Concha will also blend well. Natural slates with the words dark grey or black in their descriptions will contrast quite strongly with PV Slates.
Yes, the PV Slate received MCS accreditation in 2018. Contact us to discuss why this might be important for your project.
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.
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.
PV Slate can be fitted to pitches typically as low as 27.5 degrees. However, contact us and we will advise on the correct PV Slate product for your roof pitch and location.

Please send your architect’s drawings to us in an email to firstname.lastname@example.org 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.
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.
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.
In fire tests, PV Slate achieved AA, the highest possible rating under BS 476-3: 2004 - Roof Fire Test. AA (national class) is equivalent to Broof(t4 (European class) - the highest class.
