Q:solar panels for my home.?
Either you, or someone else, asked this same question yesterday, and the answers given were that it is not possible for us to answer it. The costs depend on where your home is located, what prevailing local labor rates are, how difficult it is to get the equipment to the site, etc, etc. I think one of the answers was that for a 3 bedroom, 2 bath house the cost for all the necessary equipment listed would be in the neighborhood of 20 to 30 THOUSAND DOLLARS. I think that was an underestimate, and that it could be 40 to 50 THOUSAND!!!!! The answerer also pointed out that due to the exorbitantly high costs of the technical equipment that at this time the equipment will wear out BEFORE IT EVER CAN PAY FOR ITSELF IN SAVINGS for on the grid electricity. I agree with that. You need to discuss your wants with 3 or 4, even 5 or 6 LOCAL ELECTRICAL CONTRACTORS to get a reasonably accurate estimate of the costs!!!!!!

There are image voltaic cellular arrays on satellites, the place they are used to ability the electrical powered structures. you have probable additionally been listening to with reference to the image voltaic revolution for the final 2 many years -- the thought that at some point we are able to all use unfastened electricity from the solar. that's a seductive promise: On a vivid, sunny day, the solar shines approximately a million,000 watts of ability consistent with sq. meter of the planet's floor, and if we could assemble all of that ability we could extremely ability our homes and workplaces for unfastened.
Q:Solar Panel: Watts, Amps, Volts? mA?
. 3V 200mA. mA (milliAmp) = 0.00A; Power = 3V x 0.2A = 0.6 Watts. 2. 6V 00mA is 6 x 0. = 0.6 Watts. 3. 9V 50mA is 9 x 0.05 = 0.45 Watts. 4. 2V 50mA is 2 x 0.05 = 0.6 Watts. With the 3 Volts one you could connect it to a flashlight light bulb, that's is about the max you can get out of it. With the light bulb, polarity doesn't matter, but if you power a small transistor radio with it, then make sure the + goes to the + and the - to the -. Reversing it wouldn't work and in some cases you could damage equipment.
Q:Need Large solar panels. ?
I think you may be surprised how much energy a little cafe like that uses. Since the air conditioning, refrigerators, and other appliances are going nonstop, I'd expect the energy usage to be several times that of a normal house. If you have access to the electric bills of the cafe while it was in operation, look up the kWh's used per month. For scale, I will say that our house uses 500 kWh per month, and needs 3 kW of panels to keep up with that. Scale up to match the restaurant, as a ballpark estimate. If you don't have access to the electric bills, then go visit a similar cafe in town, or a nearby town, and ask them how much their electric bill is. If the ballpark estimate still looks doable to you, then contact a professional solar installer to get an accurate, no-obligation estimate. Most likely, the cafe will use gas heat for cooking. But if not, electricity from solar panels is probably the most inefficient way to cook. Consider having solar ovens for most of the cooking, if you have land, with gas as a backup on cloudy days.
Q:information on solar panels?
most times yes.
Q:How many wind turbines and solar panels does the world need to replace coal, oil and nuclear power?
Green technology at this stage is not viable for the long run...we don't have the technology as of yet to replace all other modes of energy...Windmill Farms are EXTREMELY ugly and kills thousands of birds and only work when the wind is actually blowing...solar is not ready for prime time, too expensive for the average joe...we should be pursuing other engines that would use less gasoline and some exist but nobody is promoting those because they are convinced electric cars are the way to go but those are a farce because we don't generate enough electricity now for homes to use, can you imagine how little we would have if all cars starting using that same energy? IT is a farce that during an economic crisis the current powers that be are wasting money on green technology garbage that won't work. We should be figuring out how to drill our own oil and get off foreign sources and build more plants to produce more electricity, not figure out how to use the little electricity we currently produce in all our vehicles...Liberals...what a concept.
Q:Please differentiate b/w mono & poly crystalline silicon solar panels.?
these solar panels are named different based on the solar cells used... mono-crystalline solar cells: As the name suggests, each cell is made from a slice of a silicon crystal, which is made by purifying, melting and freezing silicon. pol-crystalline solar cells: these are a slight variation of single crystal solar cells. they are made of slices cut out of blocks of several silicon crystals, as opposed to single silicon crystals. check the link below to see other differences between the two types (easy to understand), such as their prices and efficiency levels. there is also a third type of solar cell/panel called amorphous solar cells.
Q:How to wire solar panels?
You will have to wire them in such a way that provides the battery with the optimal voltage for it to charge, which on a car 2v battery is around 4v. You said you have some background in electronics so this shouldnt be too difficult. You can connect them straight to the battery yes. Like you said, I believe a power inverter from 2VDC to 0VAC would work just fine. PS3 pulls a lot lot lot of current though so it probably wouldnt last too long. Look up the specs for PS3 and see how many amps it is pulling and purchase your inverter based off of that. I remember trying to run an xbox in my car one time and the inverter I had didnt work because of that. Be careful working with batteries, I had one explode in my face about a month ago.. scariest moment of my life! Good luck!
Q:Solar Panel - DC motor - Rated Power ? Functionality ?
Wood? Steel tubing could be a lot lighter. Use the hardest narrowest tires you can find bicycle wheels and tires would work nicely and they can be had with really light disc breaks. As for a motor a golf cart motor is made to order. You can get an old electric golf cart and have almost all the parts you will need. Hell cover the roof of the cart with photo voltaic and have a ball. Note I stress weight savings as weight will cost you energy and with photos you won't have much to spare. You will need a battery pac of some sort lithium are a better choice than lead acid. there is a ton more to consider good luck with your project.
