It makes perfect sense to fit as big as you physically can, or afford, system on the roof of a business that's operating hours are during sunlight hours.Quote:

We've had a 13.2kw system on the house for just on 12 months. It's made an appreciable difference to our power load.Quote:

The boiling of a jug is a big user.
Kettle, HWS, Laser printers at start up. Interestingly I find Split system A.C. is fine load wise IF its left running at a reasonable setting and not trying to shift room temps a long way.Quote:

It might not be financially worth moving those panels onto your home considering install costs. We quote a bit of this, and its not really worth it when you take STC'S off the new system cost. Also depending on what panels they are, spare capacity on inverter etc....Quote:

Been on stand alone solar and batteries for 7 years now, no problems. House is very well insulated, no aircon needed with summer high 30's temps. The system would run an AC if it was needed but with high 30's outside the inside temps are low 20's. Gas for cooking, one larger bottle lasts 18 months. Wood (off the place) for heat and hot water in the winter and solar hot water for summer. The charging goes to heatsink after 10 in the summer time, need a plug in car to utilise the excess power.
4 years young, may as well reuse them.Quote:

We have one job to do soon where we have to remove 600 panels because 9 were smashed, and replace everything with new, including the inverters. Even though all the panels were fine under thermal imaging photos.
Government rebates make it not worth refitting the existing gear, it all goes to the tip.
What a waste, surely you have a good stash of spares Damien ?Quote:
