Q:Where to buy cheap solar panels?
Grimcho..I'm going to give you a secret that no-one I know of has ever spoken of..Call Your local railroad maintenance yard and/or your local oil production company..I know your probably in another part of the world where this will not apply but here its like this.. BNSF changes out every 2-5 years their 00w 24v panels...they still have a good 5years of lifetime..Oil companies change them out on their well sites every 2 years 2x 60w 24v (actually they are 2 +2vdc grids series) now if your in Italy sorry this didn't work but if your in New Mexico ..they are in Santa FE...also they have way good batteries that are wet cell and run about 600$ each that they just dump many times on the guy for asking..try it....From the E....
Q:Why dont we have a gigantic solar panel system in the warm states,stretching miles across to supply the usa?
Claire's argument doesn't make much sense to me either. First; Claire is talking about the second law ('you can only lose or break even'), not the third law ('you can't get to absolute zero'). Easily confused, but not that important! Putting a solar panel down _can_ increase the heat absorbed by Earth. Everything has an 'albedo' (the proportion of incoming light it reflects), and Earth's average albedo is about 0.3 (ie 30% of incoming light is reflected, most of which leaves the atmosphere straight away). By putting a 0.05 albedo solar panel down on a 0.3 albedo surface, you increase the amount of sunlight that is absorbed by Earth and therefore contribute to warming. This heat is re-radiated at the Earth's temperature, in the right wavelength range to be absorbed by greenhouse gases too. If you put a panel down on equatorial ocean, or a black roof, however, there is pretty much no effect (since the albedo change is small). Also, the heating effect only lasts as long as the panel is there. Most panels are estimated to last 50 years, meanwhile CO2 has a mean lifetime of 00+ years. I did some maths and found that the 00 year averaged change in radiative forcing for solar panels was negative compared to the UK electric grid, because the reduction in CO2 emissions has a larger effect than the change in albedo. If I have spare time tomorrow I'll redo the calculations and share them. The albedo change has to be considered though!
Q:Solar panel wiring trouble.?

Q:how much power do i need from my solar panels?
Complex question.... Let me try to simplify it some: Make a list of every electrical device you MUST have. Add to the list how many hours a day it is actually ON. Add to the list how many watts (listed on the label or Volts times Amps) the device uses. (If you have a measuring device, use it.) For each item, multiply volts times hours = watt-hours (this is total energy used per day). Also, add the watts column for all the devices (this is the maximum instantaneous power to be used). Your solar panels should be able to provide power for your total load, so your panel's output power should equal the maximum instantaneous power used. If you can limit how many devices are used at a time, you may be able to reduce the panel size. Look at the total watt-hours. This is the total energy. Your panels generate maximum output when they are perpendicular to the sun at noon on a clear day. They generate reduced output in the morning and afternoon. They also generate substantially reduced output on cloudy days. Also, did you want electricity at night? On cloudy days? You will need batteries.. lots of batteries. And batteries are inefficient.. figure about 50% efficiency after a few years. Basically, here is a very rough formula: Panel_watts = Load_watthours / hours_sun_daily / 60%_angle_efficiency / 50%_battery_inverter_efficiency Once you've figured out the panel's watts, watts/volts=amps. Your system can be 2V with more amps, or 48V with /4 the amps... but the watts are the same. Just the wiring is different. For the battery bank, you need to determine how much backup power you will need for nights and cloudy days. Look at the watt-hours needed at nite, multiply it by the number of days and then by 2, to allow for battery aging. Unless you only have a couple devices and an LED light or 2, it is going to be VERY expensive.
Q:Need Help, 2v Solar Panel for Emergency?
You don't have much power to work with there. You could hook it up to a car battery to give it a sloooooow trickle charge. One amp will take like 60 hours of sunlight to completely charge a car battery. You'll be able to power small radios, ones that need nine to twelve volts or so. Just position the panel a bit away from the direct to the sun angle for your 9-volt radios, right at the sun for 2-volt radios. I would not try to power any AC adapters. You'd have to buy a DC to AC inverter, a very small one, and the inverter would steal about half the energy.
Q:How much power is generated with solar panels?
The amount of electrical energy (kWh) a kW grid connected solar PV system will generate on an average day (kWh/kWp.day). There are some factors that will determine just how much electricity you can create with solar panels for your property - The size of the system, the direction that your roof faces and the angle of the roof comes next. For optimum performance, your panels will need to be on a 35-degree angle, facing south.
Q:How many Watts of solar panels?
Running an oven or stove on solar is not a practicality; too much power is needed, use gas. Ditto, heating using solar electricity is not a practicality, and AC would also be asking a lot. The other things, within limits, might be do-able. You'll be needing as many solar panels as you can fit on. If I was you I'd consult a solar installer about how big your battery bank should be once you have decided how many Watts of panels you can put on.
Q:Need isntructions for solar panel diy?
But be aware that building your own panels will cost more than simply buying ready-made ones. This was not always true, but it is today. As you can see, this kind of information is widely available for free. Beware of scam sites that have a slick pitch making unrealistic promises, trying to sell you an e-book or video of the same stuff.
