Hybrid Solar plant for isolated areas

 

Technical description

ALSOLEN 300 offers a unique advantage by producing simultaneously in isolated areas.

  • Electricity
  • Desalinated Water
  • Cold air or ice
  • Heat for industry

The combination of Photovoltaic technology used during the day and Thermal Energy Storage that delivers electricity at night time through an Organic Rankine Cycle (ORC), satisfies client’s needs.
ALSOLEN 300 solar plants are adaptable in size, power and hours of storage fitting to the customers’ requirements.

Thermal Energy Storage

ALSOLEN has opted for a high-power and cost-effective thermal storage with 25 years lifespan compatible with solar plants lifetime. Only the thermal solution can satisfy these criteria while the electric battery cannot. ALSOLEN 300 thermal storage allows to store an important amount of energy, over 100 MWhth. The energy restored ensures a day and night supply, the perfect answer to mini grid load curve. 

ALSOLEN 300 storage is based on thermocline principle with rock-bed oil, thereby guarantying energy recovery at very high temperature. The storage tank is particularly designed with a mechanical strength that overcomes thermal constraints. The materials are locally sourced and local employment is highly encouraged.

Construction and maintenance

ALSOLEN 300 has given priority to easiness during the construction phase. Thanks to an innovative mobile factory where the solar field is manufactured and assembled, logistics costs are minimized and carbon footprint seriously reduced.
ALSOLEN 300 is smoothly operated, boasts a 25 years lifespan and is ecofriendly. For example, the mirrors cleaning is operated by a robot, hence saving water. 

Patented technologies

ALSOLEN has launched a thorough R&D campaign to guarantee best-in-class technology for its clients. Driven by a unique policy of constant innovation, ALSOLEN’s engineers, technicians and partners, have contributed to the registration of several patents among which:

  • Receiver: high temperature absorber
  • Reflector: a specific sensor to measure optical performance
  • Thermal Energy Storage: internal configuration for a stable thermocline

This work has led to the construction of a prototype fully representative of the multi-thermal applications. Equipped with a 4 hours heat storage system, this prototype is able to deliver simultaneously:

  • Electricity
  • Desalinated water
  • Solar cooling (air cooling and ice) through an absorption chiller
