HSL Laibacher Residential Rooftop Wiesen

HSL Laibacher Residential Rooftop
The houseowners are very satisfied with the modules‘ black appearance and the high output of the CIS thin-film modules from Solar Frontier.
HSL Laibacher GmbH was founded in 2005 in Wiesen/Spessart and specializes in photovoltaic and security systems. Created in 2009, Europe Solar Concept GmbH & Co. KG is its branch for distribution of solar modules, inverters and solar system supplies.

Today, HSL Laibacher is one of the leading installation companies for PV systems in the Rhein-Main area, with over 50 employees, and has connected more than 1,500 solar installations to the grid.

This project represents a private rooftop solar system in Wiesen with 66 CIS thin-film modules from Solar Frontier with a system capacity of 8.58 kWp installed by HSL Laibacher GmbH. The rooftop installation is expected to produce 8,065 kWh/yr and also reduce CO2 emission by 7,975 kg per year.

The homeowners selected Solar Frontier´s CIS modules to take advantage of better performance on a sub-optimal non south oriented rooftop. Even under these conditions, considered to be non optimal, Solar Frontier`s CIS thin-film modules perform better than other technologies. The excellent low light behavior as well as their shadow resistance, lead to high output levels even in the case of non-south orientation. In terms of aesthetic design the Solar Frontier modules enhance the rooftop and were selected because of their uniform black appearance which integrates very well into the surrounding residential neighborhood.
"Due to the environment and roof inclination there was only one choice of module for us: Solar Frontier CIS modules. The modules’ uniform black appearance fits very well into the overall surrounding residential neighborhood. Another convincing aspect was the high efficiency especially in case of lower irradiation angles. Our customer was so delighted with the expected output, design and mounting that we even got a few follow-up orders by recommendations."
