What is the electricity production guarantee, efficiency, power, and performance of the SOLROOF system?

The amount of energy production in the SOLROOF system depends on various external factors, such as: cloud cover, snowfall, air transparency, temperature, local shading, and dust levels.

The integrated FIT VOLT photovoltaic panels use modern PERC (Passivated Emitter and Rear Cell) technology, which increases solar energy conversion efficiency through the use of a passivation layer on the back of the cell. This solution enables more effective utilization of sunlight, reduces energy losses, and improves panel performance — especially in high temperatures and low sunlight conditions.

The use of SolarEdge power optimizers enables maximum utilization of each panel’s potential – even in conditions of partial shading or varying roof surface sunlight exposure.

Technical parameters and warranty

• FIT VOLT panel efficiency: up to 21.1%,

• Performance: 165 W/panel, 208 W/m²,

• Peak power warranty:

• min. 97.5% in the 1st year of use,

• no less than 80% after 25 years (linear performance warranty).

• Product warranty for FIT VOLT panels: 12 years.

• Warranty for steel components: 30 years (up to 60 years with XTREME [XT] coating).

Thanks to the integration of panels with the roof surface and optimal use of space, SOLROOF achieves higher spatial efficiency compared to traditional modules mounted on additional structures.
