- Q:solar panels and batteries?
- If it pulls 9 amps continuously, that's 08 watts/hour or about 2.5 kwh/day. If it only pulls half that (does it cycle?) it's about .2 kwh/day. You only want to drain a lead-acid battery 50% or so, so you'll want a 5 or 2.5 kwh battery pack. A typical setup for the 5 kwh would be two L-6 batteries in series, and for the 2.5 kwh you could use 2 T-05 batteries in series. This does not account for days of cloud. If you regularly have cloudy days, size the battery pack for two or three days of use with no input (2-3 x the sizes given above). To charge them, you typically want panels that will charge your battery at least 5% of its capacity per hour (C/20). For 2 volt nominal panels that's 0 amps for the T-05 or 20 amps for the L-6 batteries. It's good to have more than that for battery life (it cuts down on what's called stratification), so you'll want probably 50-200 watts of panels for the T-05 and 300-400 for the L-6. You'll also need a charge controller. Peltier coolers are very inefficient. You'll save money by using a regular mini-fridge and an inverter. Most mini-fridges only draw 50 watts or so, so you're talking 600 watt-hours for a 50% duty cycle. This means two T-05 batteries will give you two days of use and you'll only need 20-50 watts of panel. DK
- Q:2v about 600ma Solar Panel?
- Hey Jeff, what you're talking about is frequently referred to as a, solar battery maintainer. There are lots of places that make and sell them, I have seen them in many auto parts stores and truck stops along the freeways. Go to google and search for a solar battery maintainer, they come is sizes similar to what you are searching for, but it will be difficult to find one that is not over 4 wide. Lots of them are about the size of the top of a shoe box, maybe 2 X 6, and come with a cigarette lighter cord attached. A 2 volt model at 500 ma, or /2 amp, works out to about 9 watts, assuming the 2 volt nominal voltage panel is actually optimized for 8 volts, as most of them are. These devices are designed to sit on the dash board of your car and keep your battery charged if you leave the car for a long period of time, like at the airport for a week in the winter. They actually work for that, we've used one before. What are you planning on doing with it? Charging a battery or running a device directly? Remember if you hook it straight to a device, and the current requirements of the device are less than the available sun will develope with your panel, the voltage may climb to a level too high for your device. If you're charging a battery, this does not cause a problem. Another option is to build your own. It can be a lot of work for just one panel, I've not done it myself, but there are videos on the subject. That device in real goods is a flexible panel, known in the solar world as, Amorphous. They are still a bit experimental, the ones they made a few years ago did not hold up as well as the solid ones, and they are expensive. You can get a /2 amp maintainer for around $25. Good luck Jeff, and take care, Rudydoo
- Q:its about solar panels?
- If solar power is not practical, why do four of my friends and I have it? Actually Don M is mostly right. The factors to consider when contemplating a solar installation are numerous. For example my system will not pay for itself in utility savings in my lifetime, but I plan to sell the house soon. What I am saving on electricity costs, and the increased amount I can ask a buyer, I will come out well ahead. Cruise the Internet and look in the green search box at the top of this page, for solar panels. As you learn more, you can come back with more questions.
- Q:How much was the price of solar panels 5 years ago compared to now?
- For just 5 years ago, certainly not! Perhaps you are thinking of 50 years ago, the kind that was put on the early communication satellites? 5 years ago, there was a glut of polysilicon, so modules were actually a little cheaper than today. Solar cell makers were basically using the scraps thrown away by chipmakers. But today, more silicon goes into making solar cells than computer chips, so that bonanza is gone. We will see prices going lower this year, possibly 20% from last year, because of improvements in technology, but also an increase in polysilicon supply, and a slowdown in demand due to worldwide recession. Later this year is a good time to buy panels, if you have the cash. The industry site below tracks module prices. They used to have more data, but I guess the old data rolls off the screen with time. If you want to see the details, they'll charge you for the report.
- Q:260 watt solar panels on an rv?
- There are many other controllers, you just need to get a sense for the limitations and make sure you are working within them. Controllers are not that hard to hook up, two connections simply go to the battery, plus and minus. Then the other two go to your panel. I like to put a switch at the panel output, leave it off while you are hooking up the panel side wiring of the controller, then when you are sure everything is connected properly, and you have some kind of battery power indicatioon at the controller, throw on the panel switch and see if it is charging. Remember that a panel is a power source, and connecting it to the controller while it is in the sun is like hooking up a car headlight while the lights are turned on. Another option is to wrap the panel in a blanket and put it in the shade while you are connecting it up. Your panel has a max amp rating, Imax, which will likely be around 5 or 6 amps at that voltage and wattage. Number 4 romex will work for that, as well as medium duty AC extension cord wire, if your run is less than 30 feet or so. Take care Steven, Rudydoo
- Q:solar panels disconnected from battery?
- Know that solar panels almost always incorporate a blocking diode to prevent a battery from back-feeding through an un-illuminated panel. Know that solar panels are usually connected to a battery via an electronic switching charge controller, not directly connected. Know that when a solar panel is open-circuited (disconnected from everything) it's terminal voltage will rise to almost twice it's nominal voltage. (22V is common for a 2V panel), unless it is stored in total darkness.
- Q:Solar panel connected to battery ??
- . Make sure you got the right type of battery that allow to charge from the solar panel. 2. Make sure you use a device which I forgot the name but it will make sure the charge go one way in case the light go out so will not drain the battery while it is hook up. 3. Make sure you got the right charge from the solar panel to charge the battery. Reason is easyier to swim down the river or is it easy to swim up river.
- Q:How solar panels and furnaces work?
- Well solar panels conduct electricity from the suns waves and turns it into dc current then it is either put into a grid tie inverter to change it to AC and it makes you meter go backwards instead of forwards. or if its not a grid tie inverter it is just put into batteries as dc then changed into AC from the inverter and then used for household appliances. nothing really does run on DC that is why it has to be changed. and for solar furnaces if you mean a water heater that works by a substance here in Pa its antifreeze is heated up by the sun in the panel it is in a continous loop and that is what gets heated up the water then flows over tow of the tube that contains what ever substance such as antifreeze and heats the water.were the water and the tube that changes the water from cold to hot is called the heat exchanger. the substance is actually get heated first then the water. solar heating for water accounts for 29% of water heating in the us. Now if you mean solar furnace as in passive solar thats completely different because here in Pa if we want it our houses have to face to south to get the suns rays. (alot more windows) and there is a cement slab placed only on the south side of the house and it has insulation covering it. There is a certain type of glass that is used for this that will allow the suns rays to come in and let the heat in for the summer and also for the winter. the main place for that would mostly be the first floor of the house due to the height of the windows and the angle of the sun(pa in the summer is 73 degrees and in the winter its 27 degrees) thats when the second floor would be ok to heat the rooms. Hopefully i helped and i explained it in a way that you can understand.
- Q:Are DIY Solar panels legitimate for saving electricity?
- I used this youtube video to help me build a 2 volt system. I used this video to build a magnet motor attached to a car alternator, I used an old Ford alternator because they are cheap, then put in the voltage reguialtor that I took out of the same car. I then hooked that up to 6 2 volt batteries in series, then I used 4 500 watt inverters, I got it going about 2 weeks ago, I am waiting to how efficient it will make everything, I also do not have my entire house on it. So far I have hooked up my fridge, deep freeze, 52 plasma tv, and washer. I have not hooked anything else into it yet. I have no idea if it has enough power to turn on full load, like I said I am still toying with it, but it seems to be doing fine.
- Q:What is the principle of solar panels to convert solar energy into electricity?
- Silicon" is one of the most abundant materials on our planet, and since the nineteenth century scientists have discovered the semiconducting properties of crystalline silicon, it almost changed everything and even human thought. At the end of the 20th century, our lives were everywhere Crystal production and process can be divided into five steps: a, purification process b, drawing process c, slicing process d, the system of silicon Battery process e, packaging process.
