Q:Which stores can you buy solar panels at?
This one.
Q:Joule Thief vs Solar Panel?
Solar panels convert light energy to electrical energy with an efficiency of around 5%. A SMALL solar panel will only produce a small amount of power (watts) your joule thief circuit wont help because as you draw more current from the solar panel the voltage will drop; and your joule thief circuit just reduces the efficiency of the whole system Try adding another solar cell in series to get more voltage and more power.
Q:Which is the least expensive, yet still very efficient, type of solar panel?
Since you are asking for a rather technical answer you should be aware that solar panels come in several varieties. Two broad categories are photovoltaic panels which have achieved marketable efficiencies of around 24% and solar thermal panels which are routinely achieving efficiencies of between 60 to 80% while they are also much cheaper than photovoltaic panels. So the short answer is solar thermal panels. But what can you do with solar thermal energy. The answer is just about everything you can do with light energy. Sometimes additional equipment makes the efficiency drop to near that of photovoltaic panels. The trick is to keep the devices as simple and as efficient as possible. Solar thermal can of course be used to heat our homes. But it can also be used directly for air conditioning. The type of air conditioner uses a slightly different principal but it is one of the oldest that was once used in ice houses before refrigerators. It is known as an absorption system. At some point you may want to make electricity from the sun's heat. The most efficient commercial systems are not photovoltaic but solar thermal. There are several commercial systems where increased scale improves efficiency. The most efficient is a solar parabolic dish system combined with a stirling engine. At around 30% efficiency it beats photovoltaic and other thermal systems. At this level of commercial development, the various systems are more often described as solar collectors rather than panels.
Q:Adding Solar Panels to my home in Portland, Oregon?
I wish it was that easy! Maybe it will be soon. But at this time, no, there isn't. And if you have a solar collection system, you have to have a way to store the energy when you're producing more than what you are currently using. That usually involves an expensive battery array. But it's necessary. The power coming directly from the solar panels will be erratic and sending it to the battery array for storage and then use allows for the home to draw a consistent level of power. And this battery system also allows for storage of electricity for use when the sun isn't shining like at night. The system should be set up to use your power first, then go to the grid. It should also allow for distribution to the grid when your system has stored all the power it can and that's when your meter will run backwards and the power company will be paying you! There are a lot of federal and state income tax rebates for alternative energy installation costs. Check out what Oregon might toss into the package along with the Feds and see where you might come out.
Q:Why are solar panels placed on the roof of houses?
Solar panels are placed on the roof because many times the roof has good exposure to the sun providing the roof is not blocked by trees or something else so that sufficient sunlight wouldn't be absorbed. Also the panels would more likely not get damaged on the roof opposed to being in the yard. If they were mounted on the windows, how could you see? And, the windows could easily break and then what would happen to the panels? Placing the solar panels on the floor would not be practical. A lot of sunlight is needed for the cells to produce electricity and how much goes on the floor? Most roofs are at an angle which could perhaps improve the amount of sunlight the panels would get, and roofs provide a lot of unused space. The roof is the best place. Furthermore, roof solar panels are available now to blend in better with the roof so that they are more pleasing to the eye. Even if you have a small roof, some panels could be placed there provided the roof is not blocked so that the sunlight it gets would be sufficient (about 4 or 5 hours of sunlight a day is needed). And, if you needed addition panels, they could be mounted in your yard as long as the mount was close to your power box and received sufficient sunlight. I applaud your desire to use solar panels. You could possibly save 50 - 90% on your electric bill and help your environment at the same time! A Win - Win situation!!
Q:What kind of batteries to use for a solar panel?
If you will be storing them outdoors, you can use auto batteries. Indoors, use sealed marine batteries. Number and size depends on your needs. You will need a charge controller between the solar panels and the batteries to get the maximum power out of the array and to avoid damage to the batteries. And you will need an inverter to convert the 2 or 24 volts to 20 or 240 VAC. One large lead acid battery will supply about 000 watt-hours of energy, enough for 200 watts for 5 hours. You have to look at your loads and decide on how many batteries you need. Frequently it is cheaper to buy new appliances that use less power, as that power difference can save a lot of money in batteries, inverter, charge controller and solar panels. But it sounds like a few thousand watt-hours will be enough, or 2 large batteries. The real limiting factor is how much money you want to spend for the solar panels themselves. .
Q:Solar Panels?
Actually even if you cover your whole roof with panels, you wont get enugh power to even run a tv, fan and light at the same time. Solar panels give out a very less power output.
Q:how do i build a solar electric panel for my home?
Make okorder.com
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:Advantages and Disadvantages of using solar panels?
benefit: 0 value for the source of power No by way of product draw back: Unreliable extreme value to purchase image voltaic panels. Now once you're speaking approximately actually in basic terms utilising image voltaic power i.e. letting water sit down outdoors until the solar warms it up... Then I see no actual benefit to it as a results of fact it will not at all have the skill to warmth water on your needed temperature and it will take way too long.
