Q:how would you build a solar panel?
As a sandwich. Glass Space /4 inch Glass Space with copper radiator painted flat black. Box made of wood. with the inside painted black. Insulate the back side. Use water with RV antifreese. Circulate water through with a small pump. Face it toward the sun. Thermal water solar Panel.
Q:can solar panels be refurbished?
Solar water heating panels can be salvaged for the copper and aluminum in them. Unless there's catastrophic damage, solar electric panels only weaken with time. Given that serious panels have a life of over 25 years, it's debatable whether anyone would want them after they've served their useful life, any more than someone would want a 386 computer from 985 running at 6 MHz. The glass and metal could be recycled, but the acutal solar cells I think would be thrown away. Contemporary panels are made ROHS compliant with zero lead, so are not especially toxic.
Q:How to connect solar panels?
You must connect solar cells the same way you would connect a couple of batteries, in series. And you cannot connect any form of voltage source in parallel to one another, this doesn't work, if you need a specific drop in voltage from the cell, use a voltage regulator and some capacitors. Hope I helped.
Q:are there solar panel that work without the sun?
Yes and no, all solar panels can work without the sun but they mainly would not work without sunlight.
Q:Solar Battery System?
A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
Q:Solar panel wiring, materials?
the solar panel should state it, you dont need a inverter to charge, only to use the power from the cell.you do need an amp regulator, so it tells if the battery is on full charge and so the sun doesnt over power the battery through the solar panel
Q:What is the difference between monocrystalline & polycrystalline solar panels?
In regards to my research about these two types of Solar Panels, I suggest that the Monocrystalline Solar Panel would be great! It is affordable and also more convenient to install. Using a 400W Panel means fewer panels and less installation time, in addition to fewer connections and transmission losses which results in big savings and a faster return on your investment.The Topsun Solar Panels boasts efficiency of up to 6.77% and use cutting edge technology for the best heat dissipation in the industry.
Q:Need help with Solar Panels (FAQ's and opinions)?
Also crystalline silicon, but almost triple the power. I would suggest that you have a lot more research to do before just buying a panel. A single panel like that isn't immediately useful unless you have a device that takes exactly that voltage, and is not critical. A solar water pump might fall into that category. For anything else, you would need additional equipment, such as a battery, charger, and inverter. Even at these prices, a single panel is unlikely to save you money over the electric company in the long run, unless your electricity is very expensive. There is economy of scale, so larger systems can and do save money, at least for people located in the right place. If you have a remote cabin where there is no electric company, then this could be worth it.
Q:How effective are solar panels?
it depends on the size of the panel and if it is installed in an optimal location. there are many 00W panels commercially available and they can be ganged for a number of different output configurations.
Q:Why are solar panels only 0% efficient?
Sunlight comes in many frequencies, that's why it's white. Solar Photovoltaics require a photon to displace an electron from a semiconductor and that only happens at one frequency depending on what the semiconductor material is, therefore only one exact frequency gets turned into power. They are working on using organic dyes or quantum dots to absorb the energy in different frequencies and re-emit the energy in the desired frequency. They also are working on using multiple semiconductor materials to try and capture more frequencies. The rest of the energy becomes heat which also reduces the efficiency of the solar cells. The lab record for solar photovoltaics is 42.8% efficiency and quantum dots promises to be 65% to 75% efficient. Keep in mind that fossil fuels are based on energy collected by photosynthesis over millions of years. The efficiency of photosynthesis with modern plants is about 0.5% and the theoretical maximum efficiency of photosynthesis is 6.6%. All of our current energy use is based upon a small fraction of 0.5% efficiency over millions of years.
