Application of photovoltaic modules

1. Solution for a photovoltaic installation on Alugraf roofing

alugraf universal_01

System designed to offer the best anchoring solution for any type of photovoltaic module without having to drill holes in the roof.

System with an innovative expansion system that allows normal expansion of the aluminium.

Strong points:

cable clearance;
large “under module” ventilation expanse;
functional separation between roof and the photovoltaic system;
possibility of thermal expansion of the entire PV supporting system;
installation does not have to go hand in hand with the roofing;
no holes drilled in the roof.

2. Solution for an integrated photovoltaic installation on Alugraf roofing

alugraf cristallino_01

Solution devised for the application of high performance polycrystalline modules.
Our proposal entails the application of a section in extruded aluminium alloy EN-AW 6060 shaped to “embrace” the Alugraf cap without any through holes.

System designed for photovoltaic panels with the following dimensions: 512mm X 1638mm (suppliable on request).

Advantages:

cable clearance;
large “under module” ventilation expanse;
functional separation between roof and the photovoltaic system;
high yield given the same expanse;
high aesthetic yield of the roofing;
installation does not have to go hand in hand with the roofing;
the photovoltaic surface can be trod on for maintenance purposes.

3. CIGS – The new thin film technology

CIGS is the most promising photovoltaic technology made with Copper, Indium, Gallium and Selenium. These four materials make the CIGS performance much higher than any other thin film. In fact, CIGS produces more electricity from the same quantity of light compared to other thin films and therefore has a high “conversion efficiency”.

CIGS conversion efficiency is extremely stable over time which means its performance remains exactly the same for many years. Copper indium selenide (CulnSe2) has a great solar spectrum absorption capacity which allows it to use 99% of the light right with the first microns of material. This factor makes it an excellent and effective photovoltaic material. The entire solar spectrum is covered by adding a tiny quantity of Gallium at CulnSe2, bringing it closest to the maximum possible absorption of sun radiation, consequently increasing the voltage and performance of the photovoltaic cell.
