Now 8 yrs in as I post this at 11.00am with blue sky and full sun they are producing 3.86 KWH, in summer at this time of day we get well over 4 KWH and still get a sizable quartley cheque. You were obviously lucky in getting a good feed in rate. When I looked into it, my slate roof and 1930s construction meant the tarif available would take 20years to pay back! Now with the feed in tariffs stopped there is no incentive! It could take even longer...and I ain't got that sort of time left on the clock!

To me the cancellation by the Government of the grants and the reduction in the feed in rates to be untenable demonstrates perfectly the way the public is deceived and lied to by politicians in UK. There is little or no 'green' policy. I think that demonstrable lies or deceiving of Parliament or the electorate should disbar any politician from public office.

OK so today I powered up my MacPro with the power metering hardware and did some measurements. In 8.00 hours of various activities e.g. backup to external drive, internet browsing, email, bit of photo editing and just idling and the use was as follows: Total use = 1.8kW = 225watts/hour Max power use = 404watts Minimum power use = 212watts Unit switched off = 150mW. This is not what I expected so you need a switch that actually knocks off power to the computer as well! No very good Apple. I dont have a MacMini here in UK, I need to rectify that. I have never owned an iMac so measurements are not possible.

I have more serious problems right now. My beloved MacPro 5.1 is poorly It started crashing, now it won't start up. I was using it for processing music, I played reel to reel tapes into the computer using Felt Tip Studio software. Have used it many times before, never an issue. The computer stops responding, the clock stops then about 30 seconds later it shuts down. This can be in any application, even in the finder, working or idle, sometimes unattended. I am suspecting the power supply unit (PSU), maybe a dodgy capacitor. I have done some diagnostics which *seem* to be indicating power supply. Taking a step back, I recently (in terms of use, actually in July), upgraded the video card (GPU) to an ATI? msi R9 280X. I understand this card is recommended for the MacPro5.1, certainly 'flashed' for Mac, but it maxes the current available from the PSU, perhaps causing the PSU to stress to overload? The 280X card is 'metal compatible' enabling the MacPro 5.1 to run Mojave and makes the graphics processor available to PhotoShop and Lightroom, this has a big effect on the speed of rendering of the large image files from the D800. I have not used the MacPro much since I got the iMac in July, because I have not taken any photographs. I use the iMac for research and internet browsing etc. I only start up the MacPro for heavy duty stuff, like music and photo processing. Some users run an additional PSU purely for the GPU, I haven't seen that method used for this particular card but certainly have for larger/faster GPU cards. Currently the MacPro is almost completely stripped down, with only logic board and PSU remaining in the case. I have tried all the usuals, replaced the Pram battery, switched the RAM around and removed all drives etc. so far nothing has fixed it, it might run for ten seconds or ten hours but eventually it freezes then shuts down. I have examined the logs and the only thing I get is an uncompleted link, which I assume means unable to continue due to freeze. No mention of panic mode. I am thinking a PSU is my first move because the CPU's and RAM appear to pass diagnostics tests. The diagnostic procedure is convoluted and I need to check that I am doing it right, it's in 'Apple Tech' language, not particularly easy to follow! So currently my need is to get the electric flowing, rather than economise on it's use.

I can run myself without adversely effecting others. If others could then we would live in a much better place.  Back on topic.

Take out the HDDs, then you next boot up off a USB stick. Close down cleanly. Put drives back in and restart. It works....... Doooh so what was the problem. Dont know but now it is working again heave a huge sigh of relief.

Done that. Worked (hard) for about ten hours then froze again. Refuses to restart properly, restarts, then 30 sec's later freezes again, thereafter it only goes through 50% of startup progress bar., then stops with a grey screen, no further action. Hence my strip down. This is the Apple Tech faultfinder manual, second post. https://forums.macrumors.com/threads/mac-pro-5-1-no-boot-up-black-screen.2124447/

That could also be RAM. Checks will past RAM and pass but when it heats up then they can be track breaks or broken/dry joints.
