FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A: All products offered by OKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: What is a solar PV module?

A: A solar PV module consists of many solar cells that are connected together (typically in series) and packaged in a frame (typically made of aluminum).

Q3: What are the advantages and disadvantages of monocrystalline solar PV modules?

A: Monocrystalline solar PV modules are the most efficient type of solar PV modules, with the exception of CdTe thin film solar PV modules. As a result, monocrystalline solar PV modules are more expensive when compared to almost all other types of solar PV modules.

Q:any one know about electricity solar panels?
The charger will accept whatever current is necessary from the solar panel up to 7A. It's not like the solar panel will force 2amps into the charger/battery -- the charger will control the current going to the battery. I question whether or not the 2V panel will actually charge the battery, though, because in order to charge a standard lead-acid 2V battery you need to have about 4.5 volts applied to the terminals. Perhaps the charger has a boost circuit -- I don't know without looking at it or knowing the brand/model number, etc. The timer must be 2VDC, but, if you only have a timer that is rated for 20VAC, you can buy a small inverter that will take 2V and supply the necessary 20VAC. An inverter rated for 20 to 50 Watts should be sufficient. These usually cost under US$25. .
Q:What minerals are used in making solar panels?
Not minerals. Elements. Silicon. Found everywhere. Group III elements for doping. Group V elements for doping.
Q:how to make a solar panel?
All you need to do is to learn how to build solar panel to produce your own electrical energy through solar panels. These solar panels take and keep the energy from the sun and turn it into usable electrical energy that we can use every day in our ordinary lives. Generally, the majority of people that knew about solar panels think that they won't benefit from its use because they just work in sunny areas. That isn’t the case. In fact, the new generation of solar panels can produce a lot of electrical energy even on rainy weathers. Learning how to build solar panel is very easy: first they need to be installed (most of the time, on the roof of homes) and then they take the energy from the rays of sunshine and convert it from solar energy to electrical energy. Solar panels must be kept from shading, as shaded cells draw energy for themselves from other cells. Things you need to know: . Solar panels using monocrystalline cells have high conversion efficiency, and take up less space, but lack shade protection. 2. Solar panels using polycrystalline cells have even higher conversion efficiency, take up even less space, but still lack shade protection. 3. Solar panels using amorphous silicon cells have lower conversion efficiency, and take up more space, but do have shade protection. This can be especially important on a sailboat. Once you have determined the size and number of solar panels needed, you will be better able to determine where they will be placed. The best places depend on the roof's length and size of the panels. Take your time and think it through. The simple answer to how to build solar panel is none other than the sun. Select locations that will get maximum sunlight without shaded spots. In placing solar panels, consider the use of extra bars/braces to secure the panels. You obviously want them to remain stable.

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 Panels?
How Solar Cells Work by Scott Aldous Inside This Article . Introduction to How Solar Cells Work 2. Photovoltaic Cells: Converting Photons to Electrons 3. How Silicon Makes a Solar Cell 4. Anatomy of a Solar Cell 5. Energy Loss in a Solar Cell 6. Solar-powering a House 7. Solving Solar-power Issues 8. Solar-power Pros and Cons 9. Lots More Information 0. See all Physical Science articles You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
Q:The voltage and power problems of solar panels
In general, the charging voltage is 1.5 times the battery voltage as well, that is 12V battery pack, select the 18V solar panels just.
Q:What if anything has been done to channel light power other than solar panels?
Have you seen the industrial solar power tower they built in Spain? It has a very large collection of mirrors which direct sunlight toward a single point at the top of a large tower. There a boiler turbine generates a lot of electricity! It is a genius concept that could easily be installed in North American deserts.
Q:How many LED's can power a solar panel?
Your question has a lot of science involved that I don't understand perhaps the link posted in my source for this answer could help you out? It a site containing only info on LED Lights. Good Luck
Q:Best and Affordable Solar panel for home?
Solar power systems are expensive and it takes time to recover the initial investment. The cheap solar panels that you are talking must be solar heat collectors which are most common in Asia. They are the most efficient type of solar power systems for the climate in South East Asia. They are mainly used to heat water. If you are looking for this, it will cost you about 25000-30000 for a 50-200 liter capacity. If you are looking for a solar power system only, then you can expect it to cost about 50000-60000 Rs approximately for 00 Watt/hr system. With this you can run most of the appliances and lights, fans etc. and your electricity bill will only be a fraction of what it is now. Hope this helps.
