What are the economics like?
I'm of an age where I probably won't see " break even " ( though that could change depending on energy prices).
It was a substantial outlay as I wanted to " fill my roof " with panels as much as possible, and went with the GivEnergy " All in One " as it has a stated 13.5kWh battery capacity ( in reality it's more as they over provision it )
Although there are other systems that provide power backup in case of a local power outage, this is usually in the form of a couple of sockets. The system I have is seamless and acts as a sort of whole house UPS with a constant 6kW available ( until the battery is empty of course )
I'm reasonably well clued up as it's a subject that has interested me for years. When SolarPV first became popular I considered it, priced up the cost of a system and instead of installing solar I spent the would be cost on shares in National Grid.
Recent family events have focused our minds on mortality, and we're decluttering and spending a bit of money on housing improvements and other projects. As the saying goes " no pockets in a shroud " and " you're a long time looking at the lid "
