Q:how to connect a solar panel to a motor?
photograph voltaic capability is somewhat fluctuating capability source and so it may be greater advantageous if u could save the photograph voltaic capability in a battery. The battery is then related to the motor. returned connect the motor with a zener diode to the photograph voltaic panel because of the fact if u dont u could have a case of decrease back emf producing from the motor and getting discharged interior the photograph voltaic panel that could injury it. further the battery additionally ought to be having a diode circuit which might avert it style discharging into the photograph voltaic panel. hoping that this facilitates..
Q:Composition and function of solar panels
The demand for polysilicon is mainly from semiconductors and solar cells. According to the different requirements of purity, divided into electronic and solar level.
Q:Solar panel angle question..?
You did not give the details of how the legs are attached to the panel. I did some calculations on my right triangle analysis application. Based on an assumption that the legs are vertical and attached to the bottom of the panel top, i calculated the legs must be 6.97 inches long. This compares favorably with the 8 inches you quoted. t If my assumption is true, the leg length for a 7 degree angle is 2.925 inches. The configuration, if my assumption is correct, will be a right triangle. The hypotenuse (longest leg of the triangle) is the panel length and the vertical legs are the supports. If my assumption is incorrect, edit your question to detail the support /panel configuration. TexMav
Q:Which solar panel should I choose?
the last one has highest wattage. that will bring down the total number of panels you need to meet 40 KW. you probably need 220 panels
Q:How does solar panel help/affect the economy?
As other sources of energy become more expensive due to declining rates of production, or increased costs for safety or pollution controls, solar energy becomes more practical as a method of gathering inexpensive supplemental energy. Look at the german experiment, where rooftops in germany were covered in solar panels and wired into the house system to supplement energy needs. In some places, I'm not sure about Germany, you can actually sell back surplus electrical energy to the power company if you have more capacity than you can store in the batteries attached to the panels. Keeping energy costs lower than they would otherwise be helps the economy by making growth less difficult for new and existing companies, and puts money in the hands of consumers that they otherwise would have had to spend on electricity. We need some additional innovations in battery technology and solar panels to make solar a mainstream source of energy, but replacing roofing with solar panels is a very interesting idea that might become a mainstream building practice if the cost of other kinds of energy keeps rising.

Q:will a 5v 52watt solar panel charge four 2c dv 55ah batteries?
OK your math on the solar panel looks correct, but you are missing some critical information. What is the load on your batteries and for how long is this load being applied. Calculate the amp-hour load to see if your solar panel can recharge your batteries with the amount of sun light available. A safe engineering standard is to have twice as much capability as required. If you have a 200 amp load for 7.5 minutes, this would be a 25 amp-hour discharge and will take your solar panel over 7 hours to recharge your batteries. Your solar panel can easily charge the batteries up to full capacity with out any load on the batteries, if the batteries are 50% discharged, this will take about 32 hours. CAUTION! I am assuming that you are hooking the batteries up in a parallel connection, that will give you over 200 amps of current. You should charge each battery up to full charge before you connect them together, if they are not at the same exact voltage when you connect them together, they will self adjust so that each battery is at the same voltage level, at 55 amps this could be a very large spark. Each cell, there are six (6) cells in a 2 volt battery, should be at 2.7 to 2.2 volts DC per cell at full charge. Make sure your battery has a voltage 3.02 to 3.26 volts open circuit or no load. This should be full charge if your batteries do not have this voltage level, say one battery is at 0 volts DC, it could have a dead or shorted cell. DO NOT use this battery until you can get it to hold a 3.02 to 3.26 volt DC level.
Q:How to tie small solar panel system into my house's electircal system?
For one thing, you would be trying to supplement the entire electrical grid. Same reason you must have a cut out relay for an emergency generator. Cause without one, you generator would be trying to power the whole regions electrical system. You could set up a solar system to just power specific things, like a gate opener, etc. But thy would have to be wired separate from the house a.c. electrical system.
Q:Solar Panel?
shows some solar cookers. These might be usable instead of a barbeque grill.
