- Q:Can solar panels be installed on public parks or gardens?
- Yes, solar panels can be installed on public parks or gardens. In fact, installing solar panels in these areas can be a great way to promote renewable energy, reduce carbon emissions, and generate clean electricity to power nearby facilities or feed into the grid. Additionally, solar panels can provide shade for park-goers and enhance the overall sustainability of the space.
- Q:Can solar panels be used to power electric vehicles?
- Yes, solar panels can be used to power electric vehicles. Solar power can be harnessed to charge the batteries of electric vehicles, providing a renewable and sustainable source of energy. This allows electric vehicles to operate with reduced reliance on traditional grid electricity and contributes to a greener transportation system.
- Q:I have a panel that quot;deep breatheproduces at 4% efficiency, what can it power, It's about 4ft by 2ft
- I sincerely doubt that you have a solar panel that is 4% efficient at converting sunlight to electricity.
- Q:I am thinking of buying a 3w solar panel called the nomad 3 from goal zero. I want to charge 35Wh lithum batteries. I have heard that lithium batteries are temperatmental and without a regulated current things could get ugly.I have a couple of chargers that came with the batteries. One is a 2v car charger and another is 0-240v wall charger.Goal zero sell something called a sherpa 50, which contains rechargeable batteries and an inverster and I think they suggest that I charge my batteries indirectly through the Sherpa 50, however, the sherpa 50 is expensive at $200, and seems to have a small capacity, in addition to being extra weight that i don`t want to carry.Electronics geniuses, you are my only hope.
- Lithium batteries do have special charging requirements. I would recommend that you use the 2 volt charger that came with them to keep them happy. Automotive power systems can have voltages as high as 4.5 volts when the engine is running so there's no need to limit the output of the panel to anything less than that. Check with the charger manufacturer to see what it will withstand. Some will work with systems up to 24 volts nominal (up to 29 volts actual) found in larger commercial vehicles such as trucks and busses. If your charger will work with both 2 and 24 volt systems you might not need anything extra to use the unregulated output of the panel. Otherwise I'd recommend a shunt regulator to clamp the output of the panel to no more than 4.5 volts. That way it would dissipate (waste) very little of the panel's power, and even that would only be during those rare times when the panel is producing maximum output. Such a device could be as simple as a high power zener diode, a low power zener coupled with a power transistor, or a precision shunt regulator such as a TL43 coupled with a power transistor. A more complex way would be a to use buck/boost regulator between the panel and your charger. You might gain a slight advantage under low light conditions when the panel isn't putting out much but the overall efficiency could end up worse than the simpler shunt regulator. Under optimum conditions, I would expect it to take a full day for a 3 watt (peak) panel to charge just one of your 35 Wh batteries. Charging an intermediate device such as the Sherpa 50 through its built in charger and then using it to charge your battery through yet another charger would severely cut your overall efficiency. Depending on how long you'll be gone, it might be far more practical, reliable, and economical to just carry (or find a way to be resupplied with) a few additional fully charged 35 Wh batteries. Don
- Q:Pretty much, can solar panel's support the entire houses electrical needs generally, because I know sometimes the owner's can sell unused electricity back, any ideas or any ideas on how much the average home uses in kWh
- it depens where you live(north or south)how many solar panel you have,what grade solar panels,how many rechargeable batteries etc.
- Q:I purchased some small 3.6 v 70mA solar panels online. I have no experience with solar panels. I am confident of the layout of the parallel circuit I want to create, however I don't know how to properly connect the tabs that come from the sides of the panels. Any help on connecting them?
- Okay okorder /... That metal strip up top is negative, if you turn it around and look on the back you will see another metal strip there which would be positive. When it comes to wire, I use 24awg audio wire I got from radio shack, they only have solid wire at this gauge at my local radio shack but stranded is preferable. Solar cells are super fragile too so you're going to want to be extra careful. I then take a length of stripped wire and lay it over the silver tab, I hold it in place with some electrical tape at each end. Here is where experience comes into play, you can't use just any solder when making these connections. Well, you can but it takes a hell of a lot more time and effort to get it right. Make sure to use 96/4 silver-bearing solder. I'm not sure why but 60/40 solder does not adhere very well to the cell and usually the soldering iron has to stay on the cell for far too long which ends up discoloring it. If you need help on how to solder send me a message, you need to know how to properly tin the iron, since this is such a meticulous and unforgiving soldering job.
- Q:Are solar panels fire hazards?
- Solar panels are generally safe and do not pose a significant fire hazard. However, like any electrical system, there is a small risk of fire if there are installation errors, damaged wiring, or improper maintenance. Proper installation and regular inspection can minimize these risks and ensure the safe use of solar panels.
- Q:I would like to know how do you build a solar panel?
- At first, you will need about one square foot of thin copper plate, two alligator clips and short leads of wire, a wide mouth glass jar, tap water and salt. Cheers,
- Q:Do solar panels require a battery?
- No, solar panels do not require a battery. They generate electricity directly from sunlight and can feed the excess energy back into the grid. However, a battery can be used to store the excess energy for later use when the sun isn't shining.
- Q:can solar power panels installed at home provide enough electricity to power house hold appliainces and heat water.
- During daylight hours yes. I have just six panels, and during the summer, with feed in tariffs paid by my retailer, I hardly pay any electricity bills. Many people around me have up to 20 panels on their roof, and are gross feed in to the grid, meaning no more electricity bills. * or preferably 0 panels will ensure you never have to pay an electricity bill again.
