Over 800 million people in the world have no access to an electricity supply. A sustainable solution is available in the form of off-grid systems. These produce renewable energy from sun, wind or water in the exact places where it is needed. SMA off-grid systems are extremely robust and can therefore be modernized, even when the batterie´s lifecycle ends. Replacing old lead-acid batteries now with modern lithium-ion technology increases the efficiency and service life of the off-grid system.
Invest and keep operating, or dismantle it? Ideally, this is a question that operators of PV power plants only have to ask when a plant is nearing the end of its planned productivity period.
