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.Originally Posted by Homestar
The solar at work paid for itself inside 2 years. Still have a $2K per month bill (the Boss let’s us know at every chance). That’s a 40KW system that takes up about a 1/4 of the roof. Boss is thinking of bunging on another 40KW and we might be close to covering what we use. The Supply Authorities have no issues with big solar installations in industrial areas as the overall consumption is still way more than all the solar put together in our area - by an order of magnitude. In fact there probably isn’t enough roof space everywhere to make that happen, even if there was a desire for all businesses to do it.
My 8.51kw system on my house will pay itself off within a year, might just fit another 6.6kw on the carport when built, fit a battery (once we develop our hv ac battery), induction cooking, hotwater heating during the day via a Catch Green power diverter, and my running costs will be near non existent.

SubscriberWe've had a 13.2kw system on the house for just on 12 months. It's made an appreciable difference to our power load.
I have the HWS on between 10:00 and 13:00, without an issue so far and use the washing machine and dishwasher during daylight hours. I tested the A/C over summer and it uses around 6kw-7kw, so still within tolerances, with 5kw to play with.

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.
Getting advice on upgrading at work and seeing if I can shift those panels to home when my favorite sparky has time

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....Kettle, HWS, Laser printers at start up.

Probably right thanks. Recycling works a bit for me. Both home and work is almost exactly the same systems about 4 years old so have lots of life left in them. Happy to do a lot of the work myself so suspect it will be also mates rates for the home effort. Sparky to unplug and do the roof install once I put them all up there

the world was warned and you called these people "greenies" with a sneer on your face.
now you are all whingeing and complaining , expecting someone else to be your saviour.....one bloke supposedly tried that and failed.

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.Probably right thanks. Recycling works a bit for me. Both home and work is almost exactly the same systems about 4 years old so have lots of life left in them.

We have been removing a lot of systems off roofs lately due to a hail storm we had 8 months ago, 1 smashed panel, and its more financially viable to upgrade the whole systems due to STC'S. (Panels had to come off anyway for roof repairs).
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.

Yeah we have heaps of panels, hundreds of inverters, all of no use due to CEC guidelines. We give away as much as we can to mainly hippy communes for their small offgrid homes, but even they have surplus to their needs.
There is only so much that is recyclable, at this point in time, panels are not cost effective to do.
