Here's a concrete example:

Evergreen Solar makes a 200 watt panel (model ES-A-200). In real world conditions these panels should kick out 150 watts each. So to get 1,000 watts, you would need no fewer than 7 panels to do the job. Currently, this panel goes for about $1,000 each so your lookng at $7,000 just for the panels. You will also need a charge controller, inverter, batteries (if desired), mounting hardware, etc.

    Not sure what you intend to do with the electricity from the panels but here is how you can get 1,000 watts...



    Northern Arizona Wind and Sun sells Kyocera 250 watt panels for $257, which is about $1 per watt which is close to the current market price for the larger sized panels. Four of these panels will get you 1,000 watts of power for about $1,100 (not sure what shipping is).



    If you are looking at a stand alone power system, you will need a charge controller (preferably a MPPT controller), batteries (deep cycle, flooded lead acid batteries) and presumably an inverter to make 120Vac electricity.



    If you want to sell electrictiy to the grid, you will need a grid-tie inverter.



    Or if you want grid tie AND backup power, then you will need grid-tie inverter with charger, solar charge controller, batteries, etc.

Solar panels come in different ranges of wattages.Add up the wattage of different solar panels you get e.g. Ten 100W solar panels will give you a 1Kw solar system.

Spilled small amount of water onto Logisys ps4802d2 power supply.....computer shutdown instantly.....it's been 24 hours....is it possible that it will reset and power-up?


Remove your power supply. then open it and use any hair dryer to remove water or moisture. Please check warranty before open power supply case. Be careful about filter capacitor because it is not discharge then it can hold charge from which you can get sock. after removing water or moister if still it is not working then please let me know. i will give you next solution.

HP MINI 1033 CL HOW DO I REMOVE THE LCD


Tools required: A screwdriver (Phillips, the X shaped one), something pointy (fingernail, penknife).

Assuming you just want the LCD, not the whole screen assembly plastic and all.
Use the pointy object to pull out the rubber knobs placed around the edges of the panel, revealing the screws.
Use screwdriver to remove screws.
Use pointy object to pry gently between the two halves of the panel, they are snapped in place so do this gently but may require some force. Front half should come off.
Use screwdriver to remove the screws keeping the LCD in the frame.
Lift the LCD out of the frame by its edges, do this gently, they are fragile especially where the label reads on the top half 'DO NOT TOUCH THIS'.

Voila, but be careful.

I have a question, why there are 2 voltage in American market? where uses 110v, and where uses 250v? We are a manufacturer of power cords , power supply cords, we really want to know the difference ....


110V is our common household current and 220v is used where heavier voltage is needed, like ovens, stoves, clothes dryers, air conditioners, electric water heaters, arch welders, etc.

My pc just automatically turning off.. can you help me? pls..


Try using a known good working power supply in that PC. If it still turns off then you know your original power supply is good.

After that then the next thing to try is to take the processor and memory out. Take a can of air and blow some air onto the pins to make sure no dust or dirt is there and do the same for the memory.

Then go ahead and put the cpu back into its socket and the memory back into the slots.

If your still running into the same problem then the motherboard is bad at that point.

I need to install a power converter in my truck.Can any one help me with the basics? Please get back to me. Keith


What is it exactly that you want to accomplish? It looks like this unit is powered by the electrical system of your truck, but if it indeed can provide 2500 Watts of output power, its input demand from your truck electrical system will be in excess of 200 Amps!!! You'll need some pretty hefty wiring to support that type of demand, and I doubt if your alternator can put out that amount of current.
Are you sure you want/need to do this - and run it off your truck electrical system?

i don't know how much expertienc and the amount of confert you have doing this, but anyways, try taking your motherboard out of your case, and find the front panel headers(usally near the bottom right of the board, find the one labeled as pwswitch (or something similar) and use something to short the two pins,. nothing else while having CPU Powersupply ect,. or if you have a spare power button/case try that as well, if you can't fighure it out, DO NOT TRY IT and contact me and i will see about getting a picture or something

Best of luck,
Mitch
P.S. if this works then don't forget to rate me, if it doesn't work then contact me and i will see about something else(don't rate me until it is fixed or i give up(

Disclaimer: By trying this you herby release me of any liability If anything happend due to user error i assume no resonsability for injury to self, others, home or property. If you do not feel confertable doing it, DON'T, then contact me
