Saft Sunica.plus nickel-cadmium batteries store solar energy in a scheme set up by Schneider Electric to provide safe and clean electricity to residents of an isolated village.

Isolated and remote locations

Schneider Electric’s programme of social responsibility, named BipBop (Business, Innovation and People at the Base Of the Pyramid) aims to use the electrical systems firm’s expertise to provide safe, affordable and green energy to the people who need it most. With an operation in Madagascar serving the mining industry, Schneider saw an opportunity to provide a reliable off-grid power supply to the population of the village of Marovato, on the east coast of the island.

• Marovato’s 120 residents are spread across 20 houses and used only 490 W.
• Schneider specified a system to generate 1,400 W at peak times.
• 18 of Saft’s Sunica.plus 920 Ah cells were specified to store energy for night-time use.
• Batteries were selected for their long life, rugged design, operation in extreme temperatures and suitability for photovoltaic applications.

With 1.6 billion people worldwide having no access to electricity, solar energy storage can play a part in providing reliable energy.

Solar applications

Saft developed its Sunica.plus Ni-Cd battery specifically for storing photovoltaic, wind and hybrid energy in isolated locations, with many remote installations for utilities, signaling and telecoms applications. The cells can operate reliably at various states of charge and depth of discharge, wide temperature fluctuations and under mechanical and electrical abuses.
