how can i make soler panel for an house have load of more then 5kw a.c ?

Well, if you can't even spell "solar" I doubt you would have the skills to mount and solder more than 2,000 4"x4" solar cells together, add blocking diodes, and wire the whole thing up in a weatherproof frame without breaking about half of the delicate little buggers.  If you need that much power, you're not going to save much of anything by trying to build your own.  Buy some ready made.

You need two blocks in your circuit. \n\nFirst you get a thermocouple signal conditioner. There are two types analog output and digital output. If you want to get fancy use a microprocessor use a digital, otherwise go with the analog.\n\nNext you take the output signal and turn something on. \nIf the output is analog and you want to go simple you need a comparator which you add a resistor network with a trimpot to adjust the setpoint and the other input is the temp signal which then turns the load on and off.  For both types the outputs may need to drive a relay to control more wattage load since you are probably using it to control the temp.\n\nIf you are interfacing it with a microcontroller you can use a chip like this:\nhttp://pdfserv.maxim-ic.com/en/ds/MAX6674.pdf\nIt will just give you a digital temp and you can trigger the load with another output and even add a PID loop to control the temp in a smoother nicer way.\n\nIf you want the analog version try something like:\nhttp://pdfserv.maxim-ic.com/en/ds/MAX1464.pdf

In this answer I am going to refer you to an online calculator. The power company is simply trying to get an idea of your power requirements to establish a transformer and feeder size for your home. I will also tell you in this article va is the same as wattage. You will need to know the square footage of the home , whether you have gas or electric range and dryer , small appliance and laundry circuits are a given in all homes. 2-small appliance and 1 laundry . Also needed air conditioning load if applicable , or heat pump if applicable etc. If you have a copy of the National Electrical code available to you there is a sample house load section for single family dwellings that will  be helpful. But I truly feel for your purposes the following site will give you everything with a simple fill in the blanks format. If you have any questions Ill be happy to help. Ok heres the url for the calculator.  http://www.electricalknowledge.com/SFDLoadCalc.asp

Well, I applaud your ingenuity but that is already being done albeit not in massive amounts.  It is also more expensive to build a house that is solar powered but people are doing it here and there and in the long run, it does save money.  All the info you need is on the net but I doubt you can build from scratch.  You'd have to purchase kits from companies that produce solar panels and generators.

I'll give this a shot!  Typically, any metal expands in size when heated.  The Safari company that builds motorhomes in Oregon used overhead heat lamps to heat up to 40 foot long aluminium panels prior to installation on the outside walls of their motorhomes.  Once heated, the panels were riveted in place on the sides of the motorhome.  Once it cooled down to ambient temperature, the panels become very taut due the contraction. It was a quite good manufacturing method they used for years.

http://www.scitoys.com/scitoys/scitoys/echem/echem3.html#sflatpanel\nHere is a site that uses household type apparatus. simple and says it delivers some current. \n\nhttp://www.solideas.com/solrcell/english.html \nhere is another without household items but you can order the kit on here.

The first step to energy independance is to reduce to an absolute minimum.  Having electric wires coming into our homes, we have become used to unlimited energy availability.  Find ways to maximize efficiency and minimize the amount of energy required.\n\nThe only reasonable budget I've seen from someone installing a full off grid system was in a house which was far from the existing power lines.  The cost to run poles and wires was on the order of $15000.  That immediately created an option for solar / wind and off grid independance.  The home owner installed solar panels for heat and battery charging.  A wind turbine supplemented the photovoltaic system.  He budgeted energy consumption and purchased very efficient appliances.  In the end his total energy created was just slightly over calculated requirements.\n\nIf you are entering this project with dreams of living forever with free unlimited electricity you will be sadly disappointed.  The equipment and installation is expensive.  The amount of energy being created is greatly limited and you will have to cut back greatly.  You will learn not to leave the television on with no one in the room.  No more lights on in every room either.\n\nIt is a very positive project, and absolutely worthwhile.  I'm working on a small wind turbine project.  It will consist of a 800 watt generator mounted on top of an 80 foot guyed tower.  Right now it's tied up in municipal permits and other nonsense.  In the end I hope to generate about 10% of my household electrical requirements.  Payback time, assuming no downtime, maintenance or repairs will be about 12 years.  Clearly it is not a money saving investment.  I view it as a hobby to learn with and explore.  I could blow an equal amount of money in a few months on cigarettes or beer and have nothing to show for it in the end.  My justification for the money spent is to have fun with it.\n\nHave a look at the project as it has proceeded so far.  I have the wiring diagram, charge controller circuit, pictures of foundations, and so on online.  Contact information is there as well.\n\nhttp://members.rennlist.org/warren/wind.html\n\nGood luck with your project!

Absolutley, just make sure you include diodes so your batteries don't drain through the panels at night, and make sure everything is watersealed for obvious reasons

Cut a hole and mount a small enclosure cooler (alcohol vapor)\n\nIf cutting a hole is not an option then fabricate a heat sink and have the cooler blow on the heat sink.\n\nuse a simple house type thermostat for temperature control.

That's a bit high...usually want to operate at about 40-45 C or less. Get yourself a better heat sink and cooling fan, and maybe a better cooled case.

Do a search on this site..  \nregarding solar energy.

Get a ac to dc converter and just add a plug to the light bar.

It's a simple matter of adding up the power required by everything, EVERYTHING, you want connect to your supply.\n\nMachines, tools, heating, cooling/air conditioning, ventilation fans, lighting, computers, printers, copiers, telephones, fax machines, answering machines, refirgerators, freezers, water coolers, security devices, etc, etc, etc.\n\nChoose a generator with a capacity at least a bit greater than your total load, but preferably quite a bit more to allow for future load increase.

About 350 watts heat is to be dissipated from an area of about 0.5 meter square and limiting surface temperature below 100 degree celsius.

1000 watts make a kiolwatt

Good Idea..but probably expensive to hook up the equipment to some sort of generator....gotta keep the place looking clean.\n\ninresponse to answerman....(below)\nIt could be possible to keep a battery bank charged and use an inverter to run a small a/c.\nSort of like a solar setup or windmill.

Go get a new 450+W PSU. This way, there are no worries. A calculator is linked below.
