And the install hardware cost, or is this via a lease plan.
i have seriously thought about having batteries installed to complement my solar panels. With the main aim of charging a future car battery. But as I see it there is a major problem.
The average electric car battery size according to Mr Google is 40 kw. But most I have seen are far bigger.
most Battery storage systems are less than 10 Kw.
By my reckoning there is a massive shortfall in what your storing at home and what your car battery would need for a recharge. Bottom line, what you generate during the day at home, max 25 Kw in summer if your lucky will fill a battery then send out to the grid.
All that said owt is better than nowt.
A pal who has had storage batteries at home has a stackable system of batteries. Basically you just buy another battery stick it on top of the system and plug in. He has told me that with hindsight he wishes he had bought bigger batteries.
