I curently have a 4kw system, (6 panels south eash, 10 panels south west) no battery storage. Tied into the grid, set up around 9 years ago, with a FITin tarrif, returning around £700 a year.
I'm looking to make a larger system on top of the garage roof (7mx7m approx), build a shed for more panel area(7x6.5m approx). Adding around 16kw of panels. Not tieing it into the grid, as any touching of the original system invalidated the current FIT payments.
Why the need for so much power? When we are only consuming around 10kh per day on average(working from home, computers etc). I have done crypto mining in the past and looking for so a little more in the future, it uses quite a bit of electric, I find it fun. I'm likely to consume around 3.5kw 24 hours a day. Now the winter there is nothing I can do to generate enough electric to run it, so can either turn it off or pay the bill. However in the summer I have made 26kwh in a day on the 4kw system, so with a system 5 times larger I should be over 100kwh. (84kwh required to run 3.5k for 24hours) Not all days will be sunny. I do have logs of power generated over a whole year. Looks by expanding to 20kw, and with batteried I can run for over 50% of the hours over the year.
This plans will evolve this year, I need to lay the concrete base for the shed and build the shed, his will give me the roofing area for more panels. Looks like I have room for 34 panels. I'll get some draing together on this. All sketched up in 3D.
Thinking of 3 intervers to go in the shed along with 15 x 5.2kwh batteries. I see some inverters can take in mains, and output like a UPS type output. My plan would be to spply power while batteries have charge perhaps 10%, once batteries low it will switch in the mains.
However with 3 inverters, is it possible to get thme to charge batteries if enough solar present, switching to mains once batteries are low? Not suppliying any power to the grid.
'm sure I'll need to but various cables and switches, which I'll need to cost into this idea. A lot I could wire myself, and call someone in to certify it. I would with Electrinics alot and some high current DC in the past for work.
