    Currently the best achieved sunlight conversion rate (solar module efficiency) is around 21.5% in new commercial products typically lower than the efficiencies of their cells in isolation. The most efficient mass-produced solar modules[disputed – discuss] have power density values of up to 175 W/m2 (16.22 W/ft2).Research by Imperial College, London has shown that the efficiency of a solar panel can be improved by studding the light-receiving semiconductor surface with aluminum nanocylinders similar to the ridges on Lego blocks. The scattered light then travels along a longer path in the semiconductor which means that more photons can be absorbed and converted into current. Although these nanocylinders have been used previously (aluminum was preceded by gold and silver), the light scattering occurred in the near infrared region and visible light was absorbed strongly. Aluminum was found to have absorbed the ultraviolet part of the spectrum, while the visible and near infrared parts of the spectrum were found to be scattered by the aluminum surface. This, the research argued, could bring down the cost significantly and improve the efficiency as aluminum is more abundant and less costly than gold and silver. The research also noted that the increase in current makes thinner film solar panels technically feasible without "compromising power conversion efficiencies, thus reducing material consumption".

Q:Can you tie small-scale solar panel system into household electrical system?
Solar panel produces DC power that cannot be used directly by any electric device at house. Besides, it produces very little current unless its size is big as your roof. To convert DC power into AC power requires even more investment, like a huge storage rechargeable battery bank and very high power DC to AC converter . That is not worth to try it to supply whole house electricity with solar power . That might cost you at least U$20,000 to start with and never ended weekly maintenance. You could only try it just for fun to let it light up a few LED directly without the need to add any extra parts to it.

Q:How do you charge a battery with a solar panel?

Q:How Do solar panels work?
Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .
Q:How Much Do BP Solar Panels Cost In The Wholesale US Market?
Wholesale prices for BP solar panels range between $335 for the 40 watts panel to $835 for the 70 watts panel. Here's a brief listing of wholesale prices for BP solar models: - BP340J solar panel (40 watts) @ $335 - BP350J solar panel (50 watts) @ $37 - BP375J solar panel (80 watts) @ $504 Right now I'm getting a series of 50 watt (7.5 volts) panels installed in my house. It's a start to reduce dependence on electricity bills and try get some tax rebates as well.
Q:How do Solar Panels Work?
A solar panel is made up of many small solar cells. Each solar cell uses light to make electricity. The solar cell uses light to make electrons move. The cell is made up of two different layers that are stuck together. The first layer is loaded with electrons, so the electrons are ready to jump from this layer to the second layer. That second layer has some electrons taken away. It is ready to take in more electrons. When the light hits an electron in the first layer, the electron jumps to the second layer. That electron makes another electron move, which makes another electron move, and so on. So the light started a flow of electrons, or electricity.
Q:Solar Panel Charging?
With a 2 volt power source (solar panel, battery charger, vehicle charging system, etc...) you can charge three 2 volt batteries in parallel circuits then switch to a series circuit through a series/parallel switch to get 36 volts output. I've done this with my electric scooter so I can charge it with my pickup through the lighter socket when I'm away from home. It works great! When at home I just leave the switch in the 36 volt position, plug the charger in the wall receptacle and the charger puts out 36 volts. Actually 2 volt lead acid batteries have 2.6 volts when fully charged so the charging source has an output of 3.6 to 4.2 volts to effect a complete charge. In the series circuit the fully charged batteries would put out 37.8 volts so the charger would have an output of 40.8 to 42.6 volts.
Q:SOLAR PANEL ENERGY! HOW DOES IT WORK?
solar panel absorb sunshine , and it will produce electric charger, the charger move to one direction, it wil produce electric current, so it produce electricity. the electricity can through cable move to solar battery to store or to country power grid to provide electricity for people using.
Q:How can I make a sun tracker for a solar panel?
tbls0 has a good idea for the tracker, but let's take this one step farther. A clock motor large enough to move a solar panel, unless it is a very small one is going to be large, and expensive. Use the timer motor, as suggested, but attach a slotted disk to it, with a light source on one side, and a detector on the other side. As each slot comes up and allows light to pass through, this creates a one shot pulse which is used to cause a stepper motor to move position to keep the panel aimed at the sun. At the end of the panel travel for the end of the day, a switch could be set to close, bypassing the step control to put the motor into full constant speed reverse, this causing the panel to swing back to the morning position. The whole affair gets it's start up call by means of a light detector, similar to those used to turn lights off at sun up. The control would, of course be set to turn the system on to track the sun during the day. While some digital control is going to be needed, the system would not need a computer to run it.
Q:what do i have to study to install solar panels?
The only degree you will need is a degree in hard knocks.You will get it from a reliable contractor who has the skill and knowledge with the product.You may want to call the manufacture and see if there any in house schools that you could attend and be certified in their product.
