- Q: Solar panels which is the one produces the power...I wanna the complete description about it...
- I think it will be useful for you.. just try those things ..To begin, you will need a Multimeter which is able to measure DC fractions of voltage and your collection of solar cells, once you have this, position a light source near your solar cells as this will allow you to get a consistent measurement of voltage output of each of the solar cells.set your Multimeter to measure DC voltage and place the negative test lead on the side of the solar cell which shows negative voltage. Then place the positive test lead on the side f the solar cell which shows a positive voltage. Check to see what the maximum voltage output is and don’t move the solar cell around to try and get a higher reading. Next you need to separate your solar cells into groupings of .05 volt increments and this will allow you to take maximum advantage of solar cell output.the next step is to connect the solar cells with tinned interconnection wire and in order to achieve this you will need to take the spool of interconnection wire and cut it into 0.5 inch lengths.next every piece of the tinned interconnection wire should have solder put on it and you can do this by adding solder to 5.25 inches of the wire beginning at one end, then flip the wire over and add solder to the remainder of the wire beginning at the opposite end.now you must solder a length of the interconnection wire to each connection strip which is located on the front of each of the solar cells.
- Q: Can solar panels be used to power a hotel?
- Yes, solar panels can be used to power a hotel. Solar energy can be harnessed through solar panels and converted into electricity to meet the power requirements of a hotel. This renewable energy source can help reduce the hotel's reliance on traditional electricity grids and lower its carbon footprint. Additionally, advances in solar technology have made it more efficient and cost-effective, making it a viable option for powering hotels.
- Q: Hello, I am shopping for solar panels for my home and there are so many to choose from. My house uses 40 Kw of power a day. If you had to choose from the output power of a solar panel from below, which one would you choose and why would you choose it? 2 Volts 4 Amps 48Watts2 Volts 8.5 Amps 02Watts6 Volts 7 Amps 2Watts24 Volts 4.2 Amps 00.8Watts24 Volts 8 Amps 95Watts
- The most energy effiecient PV cell in Australia at the moment is from First Solar they generate the most electricity compared to all units in Australia by an additional 6%. Not much but everything counts these days, especially with prices increasing over the next thress years (even without the CPRS) projections are (by IPART, who are the regulators that sets the electricity prices) rises by 46% (thats by Country Energy) and with the CPRS it was going to reach a 64% increase. The First Solar PV cells will give you a return on investment of around 2.75 years and generate electricity for 25 years (after 20 years they still generate Approx. 85% efficiency - best in market, I know I have been researching them for ages, and these are the ones I am installing !!!. Hope this helps. You need to choose a .5kW system, this will generate Approx $380pa
- Q: How much money can you save by using solar panels?
- The amount of money you can save by using solar panels depends on various factors such as the size of your solar system, your energy usage, location, and the cost of electricity in your area. On average, homeowners can save anywhere from a few hundred dollars to several thousand dollars annually. It's recommended to consult with a solar professional to get a personalized estimate based on your specific circumstances.
- Q: Which is more efficient at producing energy? Reference(s) would be nice, but not required.
- Of course solar panels
- Q: i am looking for solar panels and wind mill to put around our house and i was wondering were to find them
- Your best bet would be to go down to a place that has magazines and look through their solar magazines, like Solar Today and Home Power. In these you'll will find many places online where you can buy solar and wind power products. They also have good reviews so that you can be an informed consumer and don't end up buying poor quality products. I've seen performance reviews on a variety of models.
- Q: Okay so.. if light deflect the light of the sun and black absorbs it, then aren't solar panels just absorbing more light, sun and heat into our atmosphere? Wouldn't this lead to an increase in global warming? Shouldn't solar panals be white? No rude answers please.
- There are two basic types of solar panels. ) Thermal absorbers 2) Photovoltaics Thermal absorbers are black in order to convert sunlight to thermal (heat) energy. The whole idea is to capture all of the light with a dark surface, convert it to thermal energy and transfer the energy into your home for water heating or space heating. If you make the surface white or reflective, then the surface will absorb only a small fraction of the available light, hence the efficiency will be very low. In other words, the panel will not produce any heat. Photovoltaic panels produce electricity instead of heat energy. Photovoltaic panels are made from thin slices (“waffers”) of silicon with special coatings on the front and back surface. One of these coatings on the front is an antireflection coating to capture the light and channel it toward the silicon. Underneath the antireflection coating the silicon waffer is coated with other chemicals that convert the sunlight to electricity. The combination of these coatings gives the panel a dark color, usually blue or black. Here's the bottom line. If you want thermal heat or electricity from solar panels, the panels have to capture the light. When that light is captured, the surface appears dark because no light (or very little) light is reflected back to our eyes. It is not possible for a surface to be an efficient absorber, capturing all available light, and at the same time appear white or bright color or reflective to our eyes.
- Q: Can u guys help on how solar panels work and how it generates electricity?(or u can give me a good website that has solar panel info on it)~Thanks in advance!~
- Solar okorder under products that are sorted by watts per area. Also go to wikipedia to get more detailed information on solar cells.
- Q: How do solar panels generate electricity?
- Solar panels generate electricity through the photovoltaic effect. When sunlight hits the solar cells within the panels, the photons from the sunlight excite the electrons in the cells, causing them to move and create an electric current. This current is then captured and converted into usable electricity for various applications.
- Q: Where in the world are solar panels used. If it is used widespread across a continent just say which continent, other than that, just name the country. So where are solar panels used often?
- Many okorder /... I have friends in Northern Michigan who use solar panels and wind generator for all their energy. They have been doing it for almost 20 years.
