Regardless of the manufacturer, all integrated systems have one thing in common - they are mounted instead of the roofing material. Below is my overview of the mounting systems available on the European market, grouped depending on the type of PV modules they use. There is more variety on the market today, though. Until recently, integrated systems were perceived as a more expensive option in the premium category. There are already over a dozen different PV solutions for pitched roofs on the market. Recently, they were also joined by Wienerberger, who announced a financial commitment to Exasun. Both Braas and Creaton have already invested in the PV integrated systems. In addition to new solutions such as Sunroof, there is also some clear engagement of big players in the roofing industry. On the photovoltaic market, there is now a clear increase in sales of mounting systems with an emphasis on aesthetics and integration with the roof. Integrated or sticked, aka in-roof vs on-roof The panels are arranged vertically and horizontally, clearly standing out from the roofing, visually resembling the block effect from a well-known computer game. The reality is that some photovoltaic sellers squeeze in as much kW as they can and installers assemble those Tetris-like systems. Additionally, on-roof PV systems are quite often a visual torture. First of all, we need to understand that solar roof tiles are completely unnecessary with PV panels above them. However, for new or refurbished pitched roofs, this is not cost-effective. On-roof mounting systems still have the largest share in the residential solar photovoltaic market.
