Q:How many solar panels have ah?
The area of ​​the solar cell chip is not exactly the same as the area of ​​the solar package panel, because some solar panels, although large, single solar wafer arrangement gap is wide, so that the solar panel power is not necessarily high. 2, in general, the power of solar panels is the bigger the better, so that the current generated in the sun, and soon it will be filled with built-in battery.
Q:projects using solar panels?
I have done this in my project too and a solar panel, two wires, a circuit/project board, an LED light/a small fan,a switch and a solderer. Just solder the wires to the positive and negative parts of the panel, put the wires connected to the panel to the board put the LED's on the other side and the switch together with it shine light on the panel and the light/fan will work.(If it dosen't work, please DO NOT consult ME.)
Q:Hey. I need some help with solar panels and batteries :) Please see the detailed version beneeth :)?
One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .
Q:Which spectrum of sunlight generates the electricity in a solar panel?
I think it's in the Ultra-Violet range because Solar Panels will still put out almost full power on an overcast day.
Q:What is the most efficient solar panel?

Q:Solar panel for your home?
In the short, a solar panel is composed of many solar cells...all tied together and in some sort of a frame for mounting. When energy from the sun hits it, it creates a reaction which can feed electricity through leads to a converter system which takes the Direct Current power and converts it into Alternating Current. If you rewire your house for DC products I suppoes you wo'nt need the converter. but most of these systems are retro-fits. Batteries provide back up source to the system when the sun goes down. So solar is converted to electricity through the panel, which goes to your solar system which both provides power to the house and to recharge batteries. The batteries take over when the sun is down. So you will need to know how much battery capacity you need by calculating the Amp hour rating of your applicances that you normally use at night like Microwave, TV, radio, refrigerator, etc. For some depending on the appliance....water heater (if electric) or stove) then you need to figure out how many panels you need to provide your normal daily energy use, figure out how many batteries you need, set up a distribution system that gives you what you need where you want it and wa la. Once done, you will be off the grid and paying nothing from the electrical utility. Some places due to deregulations allow you to sell excess power to local utilities too, but those systems need to meet tight standards.
Q:Wanting to add solar panels to my home?
Ok, well there are also other alternative energy sources, too, besides solar. There is tidal (but you need an ocean :] ), hydroelectric (river, stream, etc.), biomass/biofuels (burning garabage), geothermal (from within the earth, pipes in the earth), wind (windmills, wind, the sun to get wind), and there are others that don't come to mind. Solar energy would cost alot to be installed, and it would take up alot of space, but once installed it pays for itself and uses little to no labor. They all have positives and negatives. All of these are clean and renewable. Here are some sites that my teacher/professor gave us (we just ended alternative energy lesson.) Well I hoped this helped!
Q:how to make your own solar panels ?
It used to be possible to get broken solar cells for free from solar cell and solar panel manufacturers and then it's just a matter of labouriously measuring the voltage and current characteristics of each fragment and soldering them in a combination of parallel and in series to get a crude solar panel with the desired output but the manufacturers have caught on and now sell the broken fragments by the pound so it's not really a cheap solar panel anymore but it's still very labor intensive and results in a fragile solar panel that is readily damaged and quickly degrades. Not really worth the trouble any more.
Q:Can A Home Owned Solar Panel Support The Entire House's Electrical Needs?
it depens where you live(north or south)how many solar panel you have,what grade solar panels,how many rechargeable batteries etc.
Q:Which is the least expensive, yet still very efficient, type of solar panel?
image voltaic thermal or warm water beats PV or Photovoltaic on a daily basis. The Mono and Poly are the main conventional. they provide years of provider and function a shown song checklist. they do no longer seem to be very warmth tolerant. production will flow down on warmer day as maximum shrink sheets will instruct. Amorphous Panels are greater warmth tolerant. they're additionally greater valuable at production with ,low easy or in part cloudy days. They produce much less what in keeping with sq. foot and want a larger section. First image voltaic produces those variety of panels. HIT by utilizing Sanyo blends those 2 together to produce a panel with the main suitable of the two structures. All PV is costly. The payoff tiers from 7-2 many years in keeping with many components.
