Beats me where you get solar panels that stop working at 40C. Most just derate by 20 to 25%. Explainer here:

Big verandahs, and a constant supply of stubbies! [bigrolf]Quote:

I worked in the desert on oil/gas in the 90's and many days the outside air temp was so high it was not believed by BOM in their little white box , but we called it in every day anyway.
BTW BOM would not publish our daily summer temperatures. Call the SW Qld Gas Centre at Ballera and ask them what outside air temp is.
Could probably do a cost analysis for you if you want. PM me your power price and KWH used per billing cycle as well as details of your largest loads - AC, how many bowsers, Kitchen equipment etc. Also need the details of the current solar setup -how many panels, etc. I could work out what sized gen, fuel consumption and maintenance costs if you want. Can get this quite accurate for you if you're serious on making a decision.
A pic of your main switchboard too if you can.
Just going on what I was told.Quote:

We are pretty much at the end of the power line and we get 6-10 power outages each year usually it is only for one day But we have been of power for 3 days once, Probably not as bad as other areas But it is a PITA.
We have 2x 3kva gensets that we fire up to run the 3 fridges and 3 chest freezers along with the TV and fans for the Missus and the computer in my office.
We can run the 2x solar panels and batteries hooked up to a 3kva inverter if we need any extra power as well.
Isn't it handy to have all that power equipment that we bought for our trips away on hand just in case [bigrolf]
It doesn't get as hot here as it does there, or at any rate, it doesn't stay that way for as long. But it still gets hot (mid forties in a Stevenson screen, higher on my verandah, and a lot higher out in the sun), but despite this, in nearly 25 years living off grid, I have not observed a significant reduction in output from the panels.
Have you priced adding a battery bank to your setup?
We looked at batteries when we put in the Solar.
Again we were told that due to our heat we would need an Air Coned shed/room for them.
This not really an option due to the fact we have allocated most of our land to future expansion.
At the moment we have received quotes for a 110kva generator & a 100kva.
I have to sit down some time today & work out which will best meet our needs?
BTW, one is a 6 cylinder turbo & the other a 4 cylinder turbo - I was thinking 6 cylinders would be better than 4, am I right?
The 6 is a Cummings the 4 is a Iveco?
