- Q: 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.
- What I would suggest is that you find a panel that is rated for 00 mA, at any voltage higher than 8 volts. A 2 or even 8-volt panel will do, because the voltage will drop to match the battery. Then I would get a diode to put in series with the panel to prevent the battery from discharging through the panel at night. That's called a blocking diode. At such low currents, a charge controller is not worth it. There is not enough power to overheat the battery, which is principally what a charge controller protects against in a larger system. Be aware that you could also simply plug a trickle charger for the battery into the wall outlet, at a cost of less than a penny a day in electricity.
- Q: what is needed beside the panels and do you need an electrician to hook it up
- The main components for a solar electric system are the panels, racks for mounting the panels, and inverter to convert the panel's DC power to AC, which can be pumped into the grid if necessary. There would also be various electrical supplies involved - wire, conduit, possibly a switch and/or circuit breaker. On the paperwork side, there's a building permit, permission from the power company to connect, and some inspections. Although it could be done by a homeowner, it's not a trivial project, and the best way to get it set up is to contract a professional solar installer. They all give free quotes, and can explain your various options when they visit.
- Q: How much space is required for solar panel installation?
- The amount of space required for solar panel installation can vary depending on factors such as the size and type of panels, the energy needs of the property, and the available sunlight. On average, a typical residential solar system may require anywhere from 100 to 600 square feet of roof space, but ground-mounted systems can also be an option for properties with ample land. It is best to consult with a solar installation professional to determine the specific space requirements for your particular situation.
- Q: Can solar panels be installed on a library or educational institution?
- Yes, solar panels can be installed on a library or educational institution. In fact, many libraries and educational institutions have already embraced solar energy and installed solar panels on their rooftops or surrounding areas. This helps them reduce their carbon footprint, save on electricity bills, and serve as a sustainable example for the community.
- Q: I have tried researching on the internet and just cant find any real answer. I know that the amount of electricity produced when taking in the suns rays depends on the placement of the solar panels but I am just looking for ball park figures. Thanks

- Q: What specification of solar panel would I need to power a laptop every day? I would need to use it for about 0 hours or so every day. I don't know anything about solar panels, but I am seriously thinking of getting one now and don't know who to ask.
- I okorder / says they have DC to DC solutions from 2 V for most laptops.
- Q: Was looking at 0w solar panel kit. Does this mean, all I can use is something like a 0W CFL light bulb and nothing else?
- No. The way to set it up is to store the power generated by the solar panel in a battery, then use the battery to power your lights, radio, etc, when you need the power. A standard deep-cycle marine battery is typical for panels of this size (WalMart for approx $90). A 0W panel will generate between 30 50 Watt-Hours of power over the course of a day (May-Aug weather-dependent), so this would equate to running a laptop for -2 hours, or a 0W CFL light for 3-5 hours, or a 20W stereo for .5-3 hours, etc. I find it is much easier to speak in terms of watts. Divide the watt-hours by the watts of the appliance to get the number of hours it can run. Hope that helps!
- Q: I have a solar panel that puts out 00v, .5 amps in full sun. Before I thought it would charge a 2v battery without a solar charger but then I talked to someone and they said that it was wasting a lot of power and could potentially hurt the battery. A second part to this question is what happens if I put it on a 72v battery without a controller. Thanks!
- The solar panel is capable of /2 Amp output. If you hook it to a 2V battery directly and the battery is discharged it will want more than /2 Amp and pull the voltage down until the battery is charged to a certain level. Eventually the battery will try to charge up to 00V which will definitely damage the battery. If you use a regulator circuit running off the solar panel that outputs 2V then you will have a constant voltage circuit which will still be limited to /2A or whatever the regulator is capable of outputting. Of course you can't just go out and connect 00V to any voltage regulator it has to be capable of running from 00V and dropping the voltage to 2V like the original charger that comes with the battery. The same explanation applies to a 72V battery. You have to limit the output voltage to 72V or risk overcharging the battery.
- Q: Can solar panels be installed on community centers or libraries?
- Yes, solar panels can be installed on community centers or libraries. In fact, community centers and libraries are often ideal locations for solar panel installation due to their large roof spaces and potential for generating significant amounts of clean energy. Additionally, solar panels on these public buildings can serve as a visible example of renewable energy adoption and can help reduce electricity costs while promoting sustainability within the community.
- Q: I got an 8v solar panel for a project today, the only problem is that it came without any wires attached to it. Now i don't know what type of wires i should use and if i should solder them on or if i should use epoxy instead. Can anybody help me out?
- You might want to be careful about soldering. Some panels can be easily damaged by excess heat. Check the manufactures website for recommended attachment methods. Solder tape or conductive epoxy might be better. If you do not have such things already, a good idea might be to take it into a TV repair shop or electronic hobbyist store. Some folks are kind enough to do it for you for free.
