Okay i have a question i wonder if anyone could answer or give a rough answer too please
If i had a ryzen 1700
32gb of ram 3000mhz
a gtx 1060 maybe a 1070
and a 600 watt power supply

In england how much would something like that cost in the electricity bill if that pc was on 24 hours a day for a whole month im just curous

Thanks
 
A quick google suggest the current average kwh price in the UK for electricity is approximately 14pence. If we take that and assume your PC idles on average per day at 100watts (idle will be much lower, and gaming or intensive stuff or something you might leave running overnight may be much more; without a usage scenario it is hard to predict).

100 watts = 0.1 kwh
0.1 x 0.14 = 0.014 pounds per hour
0.014 x 24 = 0.34 pounds per day
0.34 x 30 = 10.08 pounds per month
 
Massively depends on how much you're paying per unit of electric and also how long the pc is idle vs fully loaded.

If we're assuming fully loaded (why else would it be on all day?) about £25 a month? Assuming 14p per unit and 250w average in a 30 month day.
 
Some electric tariffs are more complex as they have a day and/or night rate, or a rate that is increased on the standard rate after X number of units used per day.
 
My mining rig with 4 older gpus draws 200w at the plug. Works out about 60p a day less what I get from my solar panels.
Worth getting a power monitor to plug the PC into to get a better idea of power drain. (About £10 from the rainforest).

Slightly off topic but im currently testing a customers equivalent to a tesla power wall, stores power from 8 solar panels in batteries and then you use it when you want. im using almost zero energy from the grid and only need about an extra 30% more panels/storage and i could be off grid. however a marathon gaming weekend did see it drop a fair bit of energy. i have had a few days completely "off grid" but the weekends when the kettle is going and washing machine working its balls off it runs out of juice. however he is installing a second battery soon so lets see how that goes.

How many kw are your panels rated for? What about the battery kw rating? Most important how much does a set up like this cost?

I believe the panels can produce "upto 3kw" for the total array but 2-2.5 is what they seem to be producing. I am not sure what KWH the batteries are i will find out, Its a Garden bench full of batteries. They are trying to compete with the tesla type products but this product has not officially launched yet. if i had two garden benches im fairly sure it would be enough to be off grid if i was sensible managing the power usage. The downside to my system (its not the biggest they will do) is its only got 12kw output so chuck the electric oven on/ kettle/dishwasher and washing machine and your pulling too much. but they can change the inverter size. I will write a little post here when we have finished testing as other may find it interesting. I think in an ideal world you will need more panels than i have as this time of year there is obviously less charging going on compared to summer.
