As I said, 99 percent are grid tied no battery. You are the one percent and I think that is an important omission on your part. Your battery pack would cost around 40,000 U$ I estimate alone. Now if you are not grid tied, your solar installation will be very inefficient and often not matching your usage/charging requirements. Thus you won’t be getting the most out of the 6kwh solar panels. Often getting very little return. If it is grid tied which provides access to store excess energy, that is the most efficient system. But if you include that battery pack and try to match best efficiency, then you need a much more complex charger/controller. Add 50 percent to that cost. I suspect your installation on nearing 100k if it is installed in such a way to take maximum advantage of the sun.
Now with the battery pack, you can utilize it to provide power at night allowing for maximum savings. But if you do this, there is no guarantee you will have any battery left for those frequent power outages you have. Thus to be reliable on battery, you must keep it at full charge at all times thus not getting any real financial returns on it. It is simply a 40,000 dollar ‘generator’ which doesn’t really make any sense both from an economical or environmental sense. The good thing is that it should last a long time if it is not discharged often. But if you operate it in daily usage, you will need to replace likely every 10 to 15 years. That is pretty expensive as well.
While simple solar panel with grid tie can be both economical and environmentally friendly, battery packs make near zero sense from a return on investment or from an environmental sense. It sounds like you are using it to protect from power failures but that means it must be at 100 percent at all times ready for power failures. And if you are doing that, just install a far cheaper generator. Not only is it far cheaper, you can have days of power failure and the environmental impact is far less then the manufacturing environmental costs of batteries.
Uh, no. My battery was nowhere near $40k. Solar + battery + installation costs wasnt even that high, and thats before the 30% rebate from the federal government. Your numbers are way, way, way off.
I am not going to lie, most of what you said makes absolutely no sense to me. Basically what happens is my solar powers my house. Any additional power that is generated goes to my batteries. If my batteries are full, excess power goes to the grid, and I get a credit that I can use later. When the sun goes down, I start drawing from my batteries. If/when my batteries hit a threshold that I set from an app on my phone (I currently have it set to 50%), my house stops using power from the batteries and pulls from the grid. In the case of a power failure, I still have 50% of my battery left to protect me from power outages, which is enough to power my house at night at regular usage for hours.
Yes, I mostly have the batteries for power failures, but 90% of our power failures are less than 20 minutes, so I don’t need it to last hours. When we do have extended outages, I just turn up my thermostat, and it will last hours.
