How Does a Solar Panel Charge Controller Work for Batteries?

If it is a charge controller that is wired between the panel and the battery only, then a 3A rating is ample. The controller only has to handle the maximum current that the solar panel can output. The panel will have (or needs to have) an open-circuit voltage that is greater than about 14V in order to actually charge the battery, whose terminal voltage will rise above 12V as it charges. The panel's open circuit output voltage typically is about 17V. The 5W rating is at the maximum power point under the illumination of 1 standard sun and at a specified temperature. That maximum power point probably is around 14V, which means the panel will deliver the following amperage to charge the battery: I = P/V = 5W/14V = 0.36A Since 0.36A is well below the 3A rating of the controller, the controller will not be overloaded when charging the battery. Some charge controllers also have terminals for connecting the load that you want to power. If that's the case, then the controller also needs to be rated to handle that load amperage or higher. If you were to connect a 6A load, then you would like to have say a 10A controller. Hope that helps.

1. How can I make a 12 Volt solar panel charge my smart phone with appropriate current and voltage?

A solar charging system is not complete without a charge controller. The charge controller takes the energy from the solar panels or wind turbine and converts the voltage so it's suitable for battery charging. The supply voltage for a 12V battery bank is about 16V. This allows charging lead acid to 14. 40V (6 x 2. 40V/cell) and Li-ion to 12. 60 (3 x 4. 20V/cell). Note that 2. 40V/cell for lead acid and 4. 20V/cell for lithium-ion are the full-charge voltage thresholds.Charge controllers are also available for lithium-ion to charge 10.8V packs (3 cells in series). When acquiring a charge controller, observe the voltage requirements. The standard Li-ion family has a nominal voltage of 3.6V/cell; lithium iron phosphate is 3.30V/cell. Only connect the correct batteries for which the charge controller is designed. Do not connect a lead acid battery to a charge controller designed for Li-ion and vice-versa. This could compromise the safety and longevity of the batteries as the charge algorithms and voltage settings are different.A lower-cost charge controller only produces an output voltage when sufficient light is available. With a diminishing light source, the charge controller simply turns off and resumes when sufficient levels of light are restored. Most of these devices cannot utilize fringe power present at dawn and dusk and this limits them to applications with ideal lighting conditions.This should work in principle but is not recommended. The charge controller transforms the incoming DC voltage from the solar panel or wind turbine to the correct voltage range. In bright sunlight, the voltage of a 12V solar panel can go up to 40V, and this could damage your device.So following precautions should be taken like using a maintenance charger. A maintenance charger is usually powered by a small solar cell that provides a trickle charge to a battery on a sunny day. These devices help prevent sulfation of a lead acid battery when stroed. Even a small float charge will keep the battery at full charge.How can I make a 12 Volt solar panel charge my smart phone with appropriate current and voltage?How can I make a 12 Volt solar panel charge my smart phone with appropriate current and voltage?

2. Would you be willing to pay $11,052 for a solar panel system?

If I did not already have a system with better financials, yes

3. How fast does a solar panel's voltage switch on?

Your book help me a lot to better understand better solar installation. I seem to have a small problem with my current installation. I have bought 3 x 100 watts solar pannels, a 3500 WATTS CONVERTER, I have charged up the battery bank, connect the controller and converter as per the manufacturer specifications. For my first test I have plug my slow combustion stove fan (300 watts) to my converter. The charge controller at the beginning was indicating with its LED panel lights, that the battery were charged between 80% to 95%. After about 1. 5 hr of use, the charge controller was indicating a battery charge between 0% to 35%. Quite a drop for only a short period of usage

Which Side of a House Do You Place a Solar Panel On?
Generally, North if in the Southern Hemisphere and Southern if in the Northern Hemisphere. However for those in the tropics that can change duing the year. (For the tropics there is the option to mount them facing straight up.)1. Why isn't NASA having a ground-based solar panel to charge the Li-ion batteries on board the JPL Mars helicopter?The Mars Helicopter does have its own solar panel.It's the rectangular thing atop the vehicle.This technology demonstrator (read: special optional experiment) can fly only three minutes before recharging. But that's a lot of time for photos before landing, transmitting and recharging.The ability to make precise controls over the millions of kilometers, vehicle size and power do not allow the drone to have a "nest" atop the unnamed Mars 2020 rover2. What can I use a 6v solar panel for?Most small wind turbines, I know its not solar, are powered with an ac delco car alternator, they look very easy to make. For hot water try this, coil up several hunderd feet of water hose in a black plastic drum and put it in the sun, it will be very hot...these and others like them are simple,not solar , but simple. ..and free!!! See what you can come up with3. I have a 30 watt solar panel that puts out 1.8 amps. What size battery should I get?regular car battery will work but you will need more than one . may be 30 or more depending how much eletcricity you need when there is no sun or not enough sun. It depends on a number of factors do you have A.C. electric oven stove electric dryer ect.4. From the load side connection of a solar panel converter can a dc to dc usb type plug be hooked to it and run?as long as the voltages and type match up it should work. you might wanna check the 12v usb though because it sounds off5. Converting a solar panel (direct sunlight power) to a battery backup system? How to help!?How many amps will you need to power the pump, and how many amps of power will you get from your solar cells is the real question you need to know. Go to Radio Shack, maybe they can help you, a lot of hobbyists get electrical supplies there6. can i / should i buy a large solar panel to put somewhere in my garden, to power the garden lights?It would work but would be more cost-effective to use solar lights. The good ones. Which are not sold at Walmart7. can you hook a 24volt solar panel to 12volt batterys?Never hook up 24 volts to a controller that is designed for 12 volts. Having wrong polarities is a no no too. Those are both sure ways to fry a controller8. Is there anyone trying to create a cheaper and more efficient solar panel?The most cost-effective solution, which the vast majority of new installs use today, is solar alongside the regular power company. That way, you need no batteries, and if the solar array is not producing enough at any given time, you draw from the electric company. When the array is producing more than you need, instead of just throwing that power away, the power company buys it (usually). In short, yes, you will still have an electric bill, but a smaller one. On our house, the electric bill was a little less than $5 a month, with an end-of-year settlement of an additional $2. How much does it cost? Unfortunately, that's like asking how much personal transportation costs. Some people need a van to transport the kids to soccer, some may get by with a motorcycle, others may need only a bicycle. Solar electric does not make financial sense in all areas. Our array cost $12,000 but do not use that as a guide. Yours might be 10 times that, or half that, depending on your area and needs9.
