solar panel can be bought online from ebay ...only make sure that the voltage of the panel corresponds with your inverter battery voltage and that solar panel has atleast 72 cells and also mppt controller cheapest and mosrt efficinent is available from systellar innovations who are also selling through ebay.

i have bought the pc few months back , so i am only in need to know my current wattage for this configuration , are you sure that wattage is less then 100 watt? a very good technician told me it must be more then 250 watt

can you post ebay link for solar system ?

thanks

Not likely if you dont have gpu. Cpu and display(s) will take the most + also will depend on how efficient you power supply is ( 90% rating means 90% of what it draws is used by pc ).
i think your system power consumption at load should be around 100w and less on idle/general use. Certainly, should not be 250w .

the wattage consumption I mentioned is for the configurtion which I recommended and not for your pc. for checking total wattage of your pc, u have to check your motherboard consumpotion plus consumption of each harddrives + consumption of dvd drives and any pci cards etc and add about 20% to the total. that will be the total cpu consumption + any monitors which you use (as it doesnt draw power from cpu) must be added to the above total for calculating minimum inverter wattage.

for mppt controller for solar panel

for solar panels (must have 36 cells per 12 volts and 72 cells for 24 volts etc)

my PSU is local made infact came installed with the cabinet , does it means if its 300 watt , its consuming 250 watts + power even in normal , without gpu system?

1) Power rating on psu is only for max watts that it can supply. It does not mean that it will always use that much power. Generrally, cheaper psus have incorrect labels but anyway you dont need 300 watts.

2) So if you have a PSU that is rated 80% and you have PC that needs 100W, the PSU will use 100 * (100/80) = approx 125 watts.

Maybe a UPS might be able tell how much power is being drawn ( just guessing, i never had one).
But you can get approx power use by adding max / idle power use of each component and accounting for PSU efficiency. You can search for power use of each compenent on internet. I gave example link with sample system that used ~100 watt on load and about 50 on idle for i3

the wattage consumption I mentioned is for the configurtion which I recommended and not for your pc. for checking total wattage of your pc, u have to check your motherboard consumpotion plus consumption of each harddrives + consumption of dvd drives and any pci cards etc and add about 20% to the total. that will be the total cpu consumption
Maybe its valid thumbrule for your integrated one, i dont know, but in general - motherboard and misc consumption has nothing to do with cpu power usage. They all have to be added seperately, 20% will not work for all. Example a power hungry AMD 8 core processor will use much more than an efficient i3.

Since discussion is around PC config and also power back etc..

Can someone please suggest a good power back up configuration/brand (Inverter + Battery) ? My requirement is to run 2 laptops (mainly chargin) + One 20" monitor + 1 Router + 2 Fans for about 6-7 hrs.

I have Arrow Brand, 1.5 KVA........1 Hr back up Inverter.

It easily lasts 5 - 6 hrs........

I use Desktop with 18.5" LED monitor.Use a Fan too in summer. Using since 2 years, no issues

900VA Inverter with 180 AH battery Should give around 4-5hrs
Or go with 220 AH battery
