I riped two solar panels out of some solar light and tested them. I found out that they both produce 2 volts(I have no idea on the watts or amps). Iquot;ve hooked them up to an electric motor that can be driven by a AA battery, but when I hook the solar panels up to them nothing happens. What is wrong?
to do basic electrical experiments with solar panels and motors, it is necessary to have a digital volt-amp-ohm meter sometimes called a DVM (digital volt meter). What is the voltage that the solar panels give when the motor is not connected? what is the voltage when the motor is connected? If the motor resistance is too low, then the solar panels will not be able to supply enough current to run the motor and the voltage with the motor attached will be very low. It might take a bright light on the solar panels or direct sunlight.
i really need to know howbecause im building a solar powered car for science fair :]thank you!
Hehe, if you want to build your own solar panel that looks like what you see on buildings, etc, you will probably need to be a multi-millionaire. Here is a quote from the first link in my sources list: The high-efficiency solar cells you can buy at Radio Shack and other stores are made from highly processed silicon, and require huge factories, high temperatures, vacuum equipment, and lots of money. But fortunately for you, there is a cheap way to make a solar panel yourself (see first link). I love the scitoys website, but I am not quite familiar with this particular experiment. It looks like a science fair project in itself! It also doesn't appear to put out nearly enough power to run even a small solar car. What I would recommend is buying a compact solar panel from Radio Shack or some other electronics store that you may know of. Type in solar in to the Radio Shack search box. The first item on the list may be useful to you (the solar panel battery combo). I am just guessing, though, since I don't know any of your requirements (voltage output, power output, size, etc). Also, buyer beware. This particular product has a pretty bad customer review... but then again, I find that people are more inclined to leave a bad review than a good one. Good luck... -Ubi
I have several 6v 4.5a sealed lead acid batteries. I would like to hook one of them up to a solar panel and have it stay charged from the solar panel all the time, but not overcharged. Is there a simple way to do this with an IC or something? I am only a beginner with circuits so I want it to be something very easy to make. Basically, I want it to stay charged all the time so it's available if I need it for a power out or something.Thanks.
Yes, you can purchase a solar photovoltaic array to keep your batteries charged. You will need a Photovoltaic Cell Panel that produces 27 + watts (6volts x 4.5 amps = 27 watts) at 6 volts of electricity, a Charge Controller that allows only 4.5 amps of power through to the battery and will reduce the amps as the battery nears full charge and shut off the Panel when the battery is fully charged, and a 6v. Battery. Figure you will need a photovoltaic panel capable of producing a minimum of 27 watts if you are going to charge a completely dead 6 v. battery in one day. (with a clear sky). The way the system works is the sunlight strikes the cells on the panel and releases the excess electrons in the cells, they travel along central wires to your battery and charge the battery. When the sun sets, the procedure is reversed and the electrons flow backwards from the battery, into the photovoltaic cells. That is where the Charge Controller is needed. It acts a one way gate and lets the electrons go into the battery, but won't let them go backwards to the Panel. Just set your panel in the sun at the optimum angle for the season and your latitude on earth, connect the charge controller and then the battery, and it will keep your battery charged. Don't waste your money on the small wattage solar photovoltaic systems that claim to keep your battery charged. They simply can't do it unless your battery is in like new condition and is fully charged when they are hooked up. If you battery is a few months old, the small wattage photovoltaic systems can't keep up with the loss of power from sulfation inside the battery.
Solar panel packages have different levels of power. For instance you can get a kw system but is this kw per hour or day. How does this work?
A kW is an on the spot degree of means. A kWh is a level of means produced via the years. A KW array produces an on the spot means of 000 watts. whether that could be a 2V panel which skill it produces eighty 3 amps of modern-day. In 3 hours it produces 3kWh (kilowatt hours) of electrical energy, no longer 3kW. A 3kW 2V array might produce a similar quantity of electrical energy in one hour at 079 amps.
Yes, solar panels can be installed on refugee camps. In fact, they are increasingly being implemented in many refugee camps worldwide to provide reliable and sustainable electricity. Solar panels offer a cost-effective and environmentally friendly solution to meet the energy needs of the camps, providing power for lighting, charging devices, and running essential services. They can contribute to improving the quality of life, enhancing safety and security, and supporting the delivery of critical humanitarian assistance in these often resource-constrained environments.
The maintenance requirements for solar panels include occasional cleaning to remove dirt and debris, checking for any damage or loose connections, and ensuring that the panels are receiving sufficient sunlight. Additionally, regular monitoring of the system's performance and scheduling professional inspections can help identify and address any potential issues.
No, solar panels cannot generate electricity during a blackout because they are connected to the grid and rely on it to deliver power.
I have an electric bicycle that I travel to work by, pulling a modified child carrying trailer that holds two 2 volt deep cycle batteries in series to power the 24 volt bike motor. I'm thinking about adding a 50 watt solar panel (or larger depending on the room I can make available) to charge while I'm at work and to provide some extra juice while on my more distant travels.Can I get a solar panel to charge them while they're connected the way they are: in series? Does charging work that way?I've read that in order to charge the 24 volt battery setup (if the answer to the Q above is yes), the output from my solar panel would need to be a little more than 24 volts. Is this true? If so, how many volts?Since the bike is supposed to be powered at 24 volts and I have an x-volt (x gt; 24v) solar panel connected to it, will this cause any damage to the controller or other components while running them?Will it help supply power even while the motor is being run?Thanks.
You did not give the AH rate from your 24V battery pack,therefore , unable to suggest a correct current rate solar panel. The solar panel open voltage rate at least 30V to charge a 24V cell. No harm to controller since the charging current is so small even bike is in running condition.
