Solar roofs, also known as rooftop photovoltaic (PV) systems or solar panel roofs, are roofing systems designed to generate renewable electricity using solar energy. By installing PV panels on flat roofs, buildings can transform unused roof space into a reliable source of sustainable power. Solar roofing systems help reduce energy costs, lower carbon emissions and improve building sustainability while making efficient use of available rooftop space. Sika’s solar roof solutions include secure mounting systems for photovoltaic panels alongside PVC and FPO single ply roofing membranes, providing durable waterproofing and long-term roof performance for commercial and industrial buildings.
Benefits of Solar Roofs
- Generates renewable electricity using solar power to help reduce carbon emissions
- Helps lower energy costs through on-site electricity generation
- Can provide long-term cost stability by reducing exposure to rising electricity prices
- Makes effective use of roof space by transforming rooftops into energy-generating assets
- Supports modern building design and environmental targets
- Can provide additional financial benefits through tax incentives or the sale of surplus electricity where available
- Offers a reliable energy source when combined with battery storage systems during electrical outages
- PVC and FPO roofing membranes provide durable waterproofing and long-term roof protection
- Helps improve the environmental performance and value of commercial and industrial buildings
Sika's Solar Roof Solutions
Solar Roof Mounting System with SikaRoof® Solar Mount-2
The SikaRoof® Solar Mount-2 (SSM2) is a lightweight, non-penetrating solar mounting system designed specifically for flat roofs with Sarnafil® FPO and PVC single ply membranes. The hot-air welded system eliminates the need for penetrations, helping to preserve the roof waterproofing and maintain the Sika roofing warranty. The SSM2 system is made of Magnelis® steel which is a material with exceptional corrosion resistance, thanks to a zinc-aluminum-magnesium coating that provides a self-healing effect, protecting cut or perforated surfaces.
Key benefits:
- Non-penetrating, hot-air welded installation
- FM Approved (FM 4478 approval) and wind tunnel tested
- Lightweight, ballast-free design for roofs with limited load capacity
- Compatible with Sika single ply roofing systems to maintain waterproofing integrity and roof warranty
- Fast installation with high corrosion resistance for long-term performance
- Up to 10 times more corrosion resistant than standard galvanised steel
Ideal for:
Flat roofs up to 10° with FPO or PVC membranes, particularly where maintaining roof integrity, durability, minimising weight and achieving rapid installation are key priorities.
Solar Roof Anchoring System with SikaRoof® Anchor System
The SikaRoof® Anchor System is a prefabricated anchoring solution for securing photovoltaic systems to Sarnafil® and Sikaplan® FPO and PVC single ply roofing membranes. Welded directly into the roof membrane and mechanically fixed to the structural deck, it creates a permanent, watertight connection point without compromising the roof waterproofing.
Key benefits:
- Anchor points welded into the roof membrane to keep waterprofing intact
- Suitable for flat roofs and pitched roofs up to 35°
- Lightweight system with no additional ballast required (<15 kg/m²)
- One anchor can support multiple solar panels for efficient installation
- High resistance to wind uplift and long-term durability with stainless steel components
Ideal for:
Flat and pitched roofs up to 35° with FPO or PVC membranes, particularly suited for projects requiring mechanically secured solar installations, and suitable for both new build and refurbishment projects.
