Cycle time depends on usage, so varies from property to property. We use many times the 'average' annual household electricity usages, so could be considerably lower lifespan. It also depends what you spend on the batteries - more cycles, costs more. There is not a standard one size fits all.
As with all things it depends on the quality of what you buy but your statement didnt cover that
They are warrantied for 10 years. They may last longer, and they may not. There are plenty of people who have had to replace theirs.
Absolutely but the EVE cells have a very good reputation for not failing early. Its a bit like EV batteries, so many petrol heads repeat ''You have to consider the cost of the battery replacement when it's knackered after 8 years' as we all know that really isnt the case except for some EV's with poor battery management systems eg Nissan Leaf.
That's good to hear that lifespan is increasing, but I still have to consider the warranty period as the lifespan for proper cost accounting. If they extend the warranties, that's great.
Whatever you need to do is entirely your call but again you presented the inverter life as a fact rather than your accounting method.
I would also point out that high-end inverters do cost more, so it isn't getting something for nothing.
Well, thats kind of obvious and all part of my figures quoted in this and other threads.
People will only pay a certain amount above the average house price in the area for the same size house. We have been advised that our house is already the nicest in the street and will set a new ceiling price and spending more on it may increase saleability but will not increase the value.
Well there houses for sale around here that disproves your theory, the solar and batteries adding to the price, it is likely of course that you wont get back what youve invested in the sale price but you would have reaped the benefits prior to selling.
It can't be easily moved - it requires electrical work, transporting the heavy batteries and redoing the new house's system which may not have the same layout, cabling will probably be different.
They are easily moved, the 5 kWh batteries weigh in at around 45 kg, any removal company could easily move them. The wiring is big deal either simply disconnect the LNE with the breaker isolated job done, it really is that simple with battery only system.
As far the new house, it's guaranteed the cabling will be different but not a deal breaker surely? A 32 or 50 amp feed to location where the inverter is and switch on to 30p kWh savings or more.
Yes, it can be done, but trying to coordinate alongside a house move is not something I want to bother with.
Absolutely fine, you go whatever route you wish whenever you want, I have no desire to persuade you to go for any system. I do however feel your logic and understanding is slightly flawed in places and the true picture presented to the others in this thread that are considering going the battery and/or solar route.
I appreciate your enthusiasm in this, but my mind is made up (after considerable research).
That's not a problem and I'm grateful for your 'challenge' of my statements, it's always good to have other opinions. I too did loads of research over the last 18 months before going solar + battery and then an additional AC coupled battery which I actually made myself. It's an absolute minefield of sales promising the earth, people that dont know the subject spreading rumours etc. It took quite a while to filter through and find out the true facts. I did suffer one major booboo on the way, the solar PV and battery system I had professionally installed I had not spotted that the inverter when running on batteries was only capable of outputting 3 kW as opposed to its 6 kW rating, thats what prompted me to embark on the AC coupled DIY battery.
Talking to a few estate agents recently, they say that it can go either way - some people think that having solar on the roof spoils the look of the property and don't want to have to understand the technology. To others, it's a plus point.
Absolutely, my house will be occupied by my son and his family when were gone so thats great, I would envisage my setup would need to be simplified if it was to be sold on the open market.
My 8kWh battery was only giving 6kWh after 3 years. I contacted the company and made a warranty claim, which they ignored. I downloaded a complaint letter from Martin Lewis's website and cited the Consumer Rights Act 2015 and got a phone call from the CEO of the company.
I'm sure it can happen and theres a good chance that the cells used weren't EVE cells. The chemistry has also advanced in leaps and bounds to the LifeP04 cells that we all know and love these days which are much better. BMS systems can also play a big part in battery longevity, many older systems for example didn't control battery temperature and still allowed charging at below 0 deg C. I have battery heating on mine that maintains them at 8 deg C or above.
After 3 years, the battery had become obsolete (which was probably why they were trying to ignore me and hoping I'd go away). The upshot is, they offered me compensation for the missing capacity I'd had to pay for on the electricity bill, or a discounted upgrade to a new 12kWh battery with new 10 year warranty. (Guess which one I went for)
Thats probably the move to LifeP04 which made the old one obsolete. As to which you picked it would depend on the discount, the make and how you feel about the company I guess!
