Q:how does solar panels save energy?
Solar panels don't save energy, they just utilize a different source of energy. To the extent that it replaces energy from sources which are limited themselves (such as fossil fuels), solar energy does save those resources.* The main benefits of solar energy are environmental in the sense that it is nonpolluting,* but using solar energy doesn't reduce actual power consumption. *Excludes environmental costs of producing the solar panels themselves, but these are much smaller than the environmental benefits of solar vs. fossil fuel (which has infrastructure costs of its own).
Q:Which stores can you buy solar panels at?
Canadian tire
Q:LED Lantern Charged via 6 volt solar panel?
If it has a 6 volt battery- is it marked 2 volts on an external plug? If so, there is a resistor inside to drop the potential the battery sees. The battery itself could be slipped out and recharged easily from your 6 volt panel. Just determine how much current (in Amps or Milliamps) the panel produces nominally and divide that into 4 and add one fourth of that length of time to make up for system losses. This will tell you how many hours it should charge assuming your starting voltage of the battery is above .5 volts. and the panel is at 3 volts potential or higher. So if your panel puts out amp at 0AM, you would charge for 5 hours. 4 divided by is 4 and one fourth of that is so 4 plus is 5. It is a little more involved than that, but as a rule of thumb. Also do not discharge tha lantern to the point of no light output. LEDs are efficient, but their current will add up. If it is suggest to be able to use the lantern for up to 8 hours on a charge, stick to that value. Lead acid batteries have best longevity when discharged only to 80 percent capacity. Once battery is charged- disconnect from charging source.
Q:Can cold light make solar panels power
permanent, clean and flexible three major advantages of solar cells long life, as long as the sun exists, solar cells can be an investment and long-term use; compared with thermal power, Solar cells do not cause environmental pollution
Q:Why should I use a Charge Controller for my Battery and Solar Panel based on these provided details?
Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.
Q:Is there anyone trying to create a cheaper and more efficient solar panel?
The cheapest will be solar paint where you lay down some wires and paint the panel on. Solar roof tiles are also coming along but each tile has to be wired in. Currently the target is $ a watt. The efficiencies of these panels are very low but if the cost is low enough then the efficiencies won't matter. Keep in mind that even fossil fuel is solar power, just solar power captured by photosynthesis millions of years ago, and photosynthesis has a maximum theoretical efficiency of 6.6% with most plants achieving less than % efficiency so even an inefficient solar paint already outstrips our current energy sources in terms of efficiencies. The real problem is the business model. With solar energy you can sell the panels upfront but then what do you do for an income whereas with fossil fuels, you sell every kwh and bill each month.
Q:Solar Panel Help? Beginners?
The okorder.com/... All the other sites you google/yahoo for will be advertisements. I think the author of this one was a engineering student. Hope this helps!
Q:what can i do with a calculator solar panel?
It wouldnt be worth your time really to try and hook it to a psp. You would have to build a circuit to match the voltage of the solar panel with the voltage of the psp. one of the few things i can think of would be a model windmill that used a very small solar panel to turn a very small motor attached to the rotor on the windmill. If you want a solar panel to charge your psp, look on OKorder, theres plenty of cheap low wattage solar panels that with a small solar panel regulator can put out enough 2v dc energy to possibly charge your psp
Q:Where to get solar panels in Birmingham, AL?
Any electrical contractor could likely install them, and there are several Internet businesses that sell solar panels. You likely have no place there to get the kind of large panels you need for a house. Look at your local regulations. Your utility may not allow grid-tie, so you may have to set up an off-grid system with batteries and use separate wiring or a transfer switch. One thing a lot of people neglect is hail protection. In Birmingham, you're likely to have large hail (larger than golf ball size) every couple of years in the spring. You need to work out a way of covering them in advance of severe weather. Most panels will take up to golf-ball size hail with no problem. DK PS, I've done this myself, and have considerably more information. Email if you're interested.
Q:Solar Panels for home use?
Solar panels Will give you Free hot water Heating Power to your home You need to learn how to harness it with truck batteries Ask at solar shops about wattage
