Photovoltaic Laminate (PVL)
Photovoltaic Laminate (PVL)
Photovoltaic Laminates can be applied to Dimond®Roofings range of tray products to enable solar power generation, including Solar Rib, and can be applied at the time of installation, or after the roofing profile has been installed.
Laminates are 348mm wide and available in 5.910mm and 2.585mm lengths, and in general, have a lead time of 12 weeks.
There are many advantages in the use of Photovoltaic Laminates, over traditional glass panels, with some of the key advantages being:
- Aesthetic, for example with laminate, unlike glass panels there are no obvious protrusions or exposed cabling. Photovoltaic Laminates sit in the roof tray, require no additional fixings and fit seamlessly into your roof profile. Laminates can be also used on curved roofs.
- Shade and UV tolerant
- The highest kilowatt hour yield per watt (peak) and have a high-efficiency rate even when in the shade of at a low pitch.
- Fully supported by roofing manufacturer Dimond Roofing® and only installed by recommended installers giving peace of mind in the quality of materials and workmanship.
Once a profile has been chosen for the building project we recommend you and your designer work with us on your requirements. This takes into consideration the roof design and the potential for power generation.
The key components of the installation process include:
- The roofing tray is cleaned, and Photovoltaic Laminates are applied.
- Once the laminates have been applied, wires are run from the panels to the inverter, which is generally located close to the main switchboard.
- The invertor will then be wired, and the local power authority will then be involved to connect the import-export meter and grid tie from the meter.
- If installing a profile, and then adding PVL at a later date, pre-wiring can be organised with your electrician.
Key Design Considerations
- House/farm building roof pitch is ideal north facing
- 20m2 of roof coverage = 1KW power production
- Ideal laminate lengths must remain consistent throughout the roof for residential projects.
Roof Efficiency Layout Ratings
- MonoPitch – 100% of the roof exposed. Mono pitch roofs can, if long enough, be stepped allowing for a second row of laminates to be installed on the lower section of the roof
- Gable – 50% of the roof exposed
- Hip – 30% of the roof exposed. Laminates must remain the same length and cannot be integrated with another size
- Gable with Valley – 20% of the roof exposed
- Hip and Valley – 15% of the roof exposed
Note: Not to scale, percentages are estimates and will depend on the design.
