Q:How does solar panels work?
Solar panels are built with light-sensitive panels. These panels soak up the energy from the sun's light. This energy is changed to electric power. This power is stored in batteries to use whenever / wherever it is needed.
Q:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
Q:How many LED's can I hook up to my mini-solar panel?
Typically LED's run off low voltage and 20mA or so of power (it depends what kind of led you have). That being said if one of your solar panels only provides 22mA of power then your circuit would have to be a series circuit for you to connect more than one. In a series circuit the current supplied of 22mA will go through each LED whereas a parallel circuit the current would be divided for each subsequential led. So in your case i can see you getting away with 3 or so led's before the voltage drop across each led will cause the voltage to be insufficient enough to drive anymore. Keep in mind the LED's will turn on but the first one will be bright then next one not as bright and so on. If you opted out and bought a solar panel with 200mA and 4V you could wire the led's in parallel and get 0 led's to turn on with the same brightness or intensity. Hoped that helped!
Q:Can A Home Owned Solar Panel Support The Entire House's Electrical Needs?
it depens where you live(north or south)how many solar panel you have,what grade solar panels,how many rechargeable batteries etc.
Q:Solar panel for your home?
it all depends on how much electricity you use for heating/cooling and cooking.......if you just need lights, TVs etc then you could get away with about $5-8,000 US for a system depending on how far north you live.....to go completely off the grid is near $25,000 by the time batteries and inverters and all of that is figured in....
Q:Does infrared radition occur in solar panels?
- Radiation from the sun is mostly Ultra- Violet. - There are 2 types of solar panels, Solar thermal collectors and photovoltaic cells. - Put simply, photovoltaic cells take the UV rays and produce electricity. - Solar thermal collectors (which is probabl
Q:How much does it cost a factory to make a solar panel?
First Solar recently announced that their costs to produce panels dropped below $ per watt. I don't know how much of that is accounting tricks. Of course, that doesn't mean that they would sell panels for that price - any capitalistic company is expected to drive the price up to what the market will bear. Crystalline silicon panel producers are coming in at about $2.50/watt right now for the best of them. But again, the selling price is what the market will bear.
Q:how to build solar panels?
At first, you will need about one square foot of thin copper plate, two alligator clips and short leads of wire, a wide mouth glass jar, tap water and salt. Cheers,
Q:How to build a small SOLAR PANEL that will light a 60 watt light bulb?
Making your own photovoltaic (solar electric) panel is a nontrivial matter if you want to get 60 watts out of it. If this is a science fair project, there are some possible paths that I'd suggest: ) Make your own cupric oxide panel. With just one square foot, you can harvest perhaps 0.5 mW in bright sun - enough to power a solar calculator; -or- 2) Buy a panel to light your 60 watt bulb. You could probably get away with a panel that is 6 square feet, but would use a car headlight as the lamp. If you wanted to light a regular household bulb, you would need electronics to step up the voltage, and you would lose a sizeable fraction of the energy just in the conversion. -or- 3) Buy broken solar cell pieces, or individual solar cells, and solder them together into your own panel. This is a LOT of trouble, and is a finicky process to get working and keep working. And it may not end up being cheaper than buying a ready-made panel. But you can claim that you made it! By the way, crystalline silicon panels are in the ballpark of 5% efficient, and a 3' x 3' one would produce in the neighborhood of 20 watts.
Q:Can I join 5 or more solar panels into line to the battery bank. I don,t have a regulator connected, just st?
I am pretty darn sure you need the regulator because all the advertising says that you must have one if you have more than one small solar panel. I think you can overcharge your batteries otherwise. Solar power is still not cost effective, so most people have solar power because they care about the environment more than they care about expenses. If you are poor, it is better to skip solar power, unless you are in an area where there isn't access to electricity. For example, we have a cabin without electricity. I am a strong environmentalist, too. Solar power is too expensive still, for low income people. It is better to focus on energy conservation, imo. such as change your roof to white, to save on A/C, as the head of the US energy dept. says (he is a nobel prize winning physicist). PS Dave might be right on that stuff, i don't know. but all the ads say you need a regulator if you are going to have more than one solar panel so I assumed this was due to risk of overcharging.
