See here for answers to the most commonly asked questions about our PV Slate.
Yes, the PV Slate received MCS accreditation in 2018. Contact us to discuss why this might be important for your project.
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.
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 22.5 degrees. However, contact us and we will advise on the correct PV Slate product for your roof pitch and location.
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”).
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.
Contact us to discuss tile/fibre cement slate compatibility.
Please send your architect’s drawings to us in an email to email@example.com 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.
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
With support from the Welsh Government, the Rhondda housing association RHA Wales have engaged GB-Sol to retrofit Welsh made solar panels and batteries on 12 houses in Llanharry As well as reducing energy bills and carbon emissions, the project uses panels made in our factory in Treforest, supporting our skilled technicians and the local economy.
Thank you for your interest in GB-Sol. Before you contact us you may be able to find the answer to your question here. If you would like any further information about our products, please contact us today.
