The AX203, a dedicated product

We have designed a high efficiency, low concentration solution for energy operators.

The AX203 is a unique product on the photovoltaic panel market. It has been specifically designed for sun-rich countries. The component parts were all created by our engineers with the aim of:

• optimising daily energy efficiency,
• simplifying implementation and maintenance,
• facilitating the updating of modules and increasing the performance of the power plant.

Based on proven technologies, Axiosun’s patented architecture supplies the very highest levels of performance and reliability at a low cost.

Each AX203 panel is composed of three main parts:

• the structure and uniaxial tracker,
• the reflectors,
• the photovoltaic modules.

The AX203 incorporates a uniaxial tracker which follows the rotation of the sun from east to west throughout the day and pivots over 170°. The Axiosun Tracker is powered by an electrical actuator connected to an astronomical clock. This device is placed in “safe” mode when the wind speed exceeds a pre-programmed limit.

Axiosun’s reflectors consist of high-reflectivity parabolic mirrors that concentrate the light of the sun by a factor of 20 uniformly on the modules.

Due to solar concentration factors, the AX203 photovoltaic modules are small in size (1,250mm x 100mm) but with a production equivalent to traditional panels. The AX203 module has been specially designed for concentrated solar technology. It is manufactured according to a procedure developed by the Axiosun company in order to meet the aging and temperature constraints that are specific to medium solar concentration (Standard IEC 62108). This module incorporates a concentration cell developed by Axiosun which has an excellent efficiency rate of 19% when subjected to concentrations.

 

Axiosun has developed special cells that have a high efficiency rate (19%) when concentrated. This graph shows that, when subjected to concentrations, the Axiosun cell has a high efficiency rate whilst the efficiency of a standard cell plummets.
