Characteristics:
- Long life (10-12 years)
- Many charge/discharge cycles
Energy storage is required in most stand-alone systems, as energy generation and
consumption do not generally coincide. The solar power generated during the day is
very often not required until the evening and therefore has to be temporarily stored.
Longer periods of overcast weather also have to be catered for.
The most common type of battery found in stand-alone solar systems comprises
rechargeable lead-acid-batteries. These are the most cost-effective and can handle
large and small charging currents with high efficiency.
Vehicle starter
batteries are not suitable and should not be used in stand-alone solar or wind systems. A starter battery in normal cyclical solar use with up to 50 per cent
discharge depth would soon become unusable after just a few days. Its capacity would
be reduced to a small fraction of its initial capacity.
