- Q: ASAP :) as much details as possible
- As other sources of energy become more expensive due to declining rates of production, or increased costs for safety or pollution controls, solar energy becomes more practical as a method of gathering inexpensive supplemental energy. Look at the german experiment, where rooftops in germany were covered in solar panels and wired into the house system to supplement energy needs. In some places, I'm not sure about Germany, you can actually sell back surplus electrical energy to the power company if you have more capacity than you can store in the batteries attached to the panels. Keeping energy costs lower than they would otherwise be helps the economy by making growth less difficult for new and existing companies, and puts money in the hands of consumers that they otherwise would have had to spend on electricity. We need some additional innovations in battery technology and solar panels to make solar a mainstream source of energy, but replacing roofing with solar panels is a very interesting idea that might become a mainstream building practice if the cost of other kinds of energy keeps rising.
- Q: Can solar panels be used during a power outage?
- No, solar panels cannot be used during a power outage unless they are connected to a battery storage system. Without a battery backup, solar panels will also lose power when the grid goes down.
- Q: I have a small marine solar panel on my boat It came with the boat. I want to make sure it is working before I connect it. With a volt meter It is only reading .2 volts dc. I would think it should be 2-5 volts?
- Mark, the 2 vdc is pretty typical. Most panels for home use are set up to charge 2 volt batteries, and they are wired for an, open circuit voltage of 8 to 9 volts. This allows it to have enough voltage to feed through a few diodes, perhaps a charge controller and 30 or 40 feet of wire and still have at least 5 volts left over. Once you connect it to the battery the panel will drop to whatever the batteries charging curve voltage would be. If you have a few minutes, I would suggest getting a book at the library called, The Complete Battery Book, by Richard Perez. Just read the chapters pertaining to lead acid batteries, the other discussions on lithium, ni cads and such won't apply to your boat system. If your panel is not large, and it's short circuit current rating in amps is less than 2% of the amp hour capacity of the battery, you can even run the panel without a charge controller. The book explains this as well. There is a great magazine that gets into the nuts and bolts of this stuff, it's called Home Power, you can find it online. You might also find some info at a couple renewable energy websites, I will list them below. Panels are rated in two ways, open circuit voltage, which you measure with a multimeter while the panel is in open sun and nothing is connected to it. The other rating is short cirucuit current, which you measure with an ammeter while the panel is in the sun as well. You connect the ammeter across the output of the panel and let all the power short right through the meter, so you'll need an ammeter big enough to handle more amps than the panel puts out. A 0 amp unit will work for your boat panel. These tests won't hurt the panel, or the meters, we do it all the time in the field, and the manufacturers will tell you to do the same test if you have a problem with a panel and they want to know if it's malfunctioning. You can check one of their websites if you like. Good luck Mark, and take care, Rudydoo
- Q: I'm looking to mount a solar panel to the top of my 2003 Pontiac Montana and was wondering how i could do it without any screws? Magnets maybe?
- In whichever car I'm not using much, I plug in a small solar panel to the cigar lighter socket, and simply place it up on the dashboard. So long as it gets daylight, it's working, it doesn't need full, direct sun. I just slip it between the transmission-tunnel and passenger seat when I get in, and my cars start right on the first turn of the key. It only delivers a very low level of charge, but it's STILL a net-gain, rather than the battery slowly getting a little tired - even the clock in the car, and the armed alarm-system takes SOME current to run, but even the smallest of panels will sort this out for you.
- Q: i have a 2v 2a solar panel that i want to use to charge a 2v battery .Have found out that i need a charge controller so i don't over charge the battery.I have found a cheep one its 2v but 7a will it still work ?All-so im planing on running a 2v water pump off the battery with a timer,its for watering my garden.Will the timer have to be 2v as well ?any help on this would be greatly appreciated thanks .
- The charger will accept whatever current is necessary from the solar panel up to 7A. It's not like the solar panel will force 2amps into the charger/battery -- the charger will control the current going to the battery. I question whether or not the 2V panel will actually charge the battery, though, because in order to charge a standard lead-acid 2V battery you need to have about 4.5 volts applied to the terminals. Perhaps the charger has a boost circuit -- I don't know without looking at it or knowing the brand/model number, etc. The timer must be 2VDC, but, if you only have a timer that is rated for 20VAC, you can buy a small inverter that will take 2V and supply the necessary 20VAC. An inverter rated for 20 to 50 Watts should be sufficient. These usually cost under US$25. .
- Q: Can solar panels be used to power a film set?
- Yes, solar panels can be used to power a film set. By harnessing the sun's energy and converting it into electricity, solar panels can provide a sustainable and renewable source of power for various film production needs, such as lighting, cameras, and equipment. This not only reduces the carbon footprint of the film production but also saves costs on traditional energy sources.
- Q: Do solar panels require permits for installation?
- Yes, in most cases, solar panels require permits for installation. The specific requirements and regulations vary depending on the location, but obtaining permits ensures that the installation meets safety standards and compliance regulations set by local authorities.
- Q: Im doing a science project and I need to know what gases or liquids a solar panel can make that is not friendly to the environment. Please name all the gases and liquids and explain how they damage the environment. It would be most likely that you will get best answer if you find all the bad things about solar energy and explain why they are bad and how they affect nature. that would be helpful to. Thank you
- Once okorder /
- Q: Can anyone give me some info on how to figure how many panels needed for a 0 volt 2 amp pool motor. Thanks/ Run 5 hours a day
- I don't think heating a 70,000 gallon pool with solar panels is practical. My husband has designed and built our solar hot water system. It works quite well. We live in Arizona. There's no way we could heat that much water using sun energy. You have to heat the water and compete with the outside air.
- Q: i need as many bad things there is about solar panels
- They're really expensive. If you want it for practical use like a house or car powering system. They're bigger than like a battery if you're comparing size to power. Like a car battery can produce more energy than a 6 x 4 panel (just an example)
