That 1000 is for NMC batteries and its a 70% capacity. Still enough to be useful.

Also, there's a lot of factors that go into play. For example, this assumes the batteries are fully charged and discharged. If you do something smarter like going down to 40% and up to 80% then they end up being able to do a lot more cycles. In fact, battery age starts mattering more than the cycles.

But besides that, LFP batteries are currently being used in home battery storage (including powerwalls) because it's cheaper and it has 5000->10,000 cycles before dropping to 70% capacity.

Generally, though, I'd agree that having more generation throughout the day is better than having perfectly optimized generation.
