Should be also noted that the lifespan of PV cells is underestimated. Ive seen panels that were a good 15 years old and they were still putting out power that was at the advertised spec.
Lithium batteries have a far longer life than the lead acid types that are commonly used and their price has come down somewhat, something else to take into consideration is the future power costs over the time your investment returns to you.

The better quality PV panels also understate their generation capability. The PV array we had at our previous property consisted of 24x 215W BP brand panels. That suggests that we could expect 5.16kW in total but I've seen the inverter reading just over 6kW of input at times.

Also worth repurposing EV battery packs if you have the technical skills to do so. Even an early Nissan Leaf's battery with 50% State of Health still has 12kWh of usable storage (approximately that of a Tesla Powerwall) despite being regarded as providing insufficient range for powering the car. There are plenty of older Leafs to be had for less than $5,000 that would make perfect donors for such projects. (A Powerwall is about 3x that price).
