Cost effective, reliable and innovative stand alone photovoltaic system

Objective



PROJECT OBJECTIVES

The CRISTAL-PV project objective is the development of a low cost and small complete PhotoVoltaic system. This system is dedicated to remote areas in Europe, to provide houses and small devices with a cheap yet reliable maintenance free PV system. In developing countries, this installation will provide a reliable low cost equipment. Since every part is designed for the application, a real warrantee will be considered.

The CRISTAL-PV system aims at very low production cost (20% less than the present offer) implemented through an innovative design allowing reduction of the cost of all the parts of the installation, without sacrificing the reliability. The main R&D objectives are:
- the development of innovative technical solutions concerning the PV generator, the charge control unit and the battery;
- the optimisation of the overall performance of the complete system, by finding the best fit between the PV module and battery characteristics; - the standardisation of components and the preparation of moss production of PV systems, in order to achieve low costs.

TECHNICAL APPROACH

The CRISTAL-PV system will be composed of a 12V PV panel with an integrated regulator and a 12V/l00Ah new innovative maintenance free lead acid battery generation. The technical innovations are focused on the following aspects:
- an energy storage battery able to be produced at low cost around 40 ECU per kWh) but this battery will be adapted to specific PV requirements: maintenance free, improvement of the cycling service life trio acid stratification), integrated protection against abusive discharges.

- a low cost frameless solar module with simplified supporting devices having reduced number of modules thanks to higher efficiency. Furthermore, a new integrated regulation system will be developed.

EXPECTED ACHIEVEMENTS AND EXPLOITATION

The achievements foreseen in this project can allow an effective increase of the small stand-alone PV system reliability and a real cost reduction of the PV energy in off-grid applications.
As these systems represent the main market share on the international PV business, the fulfilment of the objectives of the present project guarantees an improvement of the present situation: an increase of the sales of the Europeans industrial partners, and consequently a stabilisation or an increase of the European market share on the world markets.
