Distributed Photovoltaic Systems Design and Technology Requirements
This study concludes that the maximum PV penetration will be equal to whatever the minimum load is on that specific feeder. That minimum load was assumed to be 25% of the maximum load on the feeder in [13], and if the PV penetration were 25% of the maximum load, only insignificant overvoltages occurred.

Solar Energy Storage Systems: Everything You Need to Know
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).
