Almost all stand-alone PV plants use batteries for energy storage. Batteries are expensive and heavy, have a comparatively short life, and need permanent monitoring and maintenance. Experience with past PV installations shows that for those complex systems, battery monitoring and maintenance cannot be guaranteed in remote areas.

The federal government has installed more than 2,900 solar photovoltaic (PV) systems, and the electricity generated from these on-site systems has increased 12-fold over the last 10 years. PV systems have 20- to 30-year lifespans. As they age, their performance can be optimized through conducting proper operations and maintenance (O&M).

Most solar energy storage systems have a lifespan between 5 and 15 years. However, the actual lifespan depends on the technology, usage, and maintenance. Lithium-ion batteries generally have a longer lifespan (around 10-15 years), while lead-acid batteries may need replacement after 5-10 years (Dunlop, 2015).
