Q:How to connect 2 power supplies together? (Solar panels)?
Most solar lamps use a single .2V nicd or nimh battery as a back-up supply, so they should be able to generate at least .5V in full sun to allow charging of the battery (you can verify the voltage of a single panel with your DMM) If you have two of these panels, I wouldn't expect them to make more than approximately 3V. The proper connection would be a series connection where the negative of one panel connects to the positive of the other and the remaining positive and negative wires become the outputs. Try this connection and measure again with your multimeter set to DCV and the panels in full sun. If the voltage is not high enough, add a third panel wired with its positive lead to the remaining negative of the first two. This should bring your voltage up another 50 percent.When you wire the panels positive to positive, negative to negative as you already have, voltage will be that of one panel, but current output will double (more amps) If you have many of these panels, you could combine series and parallel wiring to increase voltage and current.
Q:solar panels for your home?
I Hope this helps.
Q:How many Solar Panels do I need?
Everyday I use ,280 kWh 280 kW-hour / 24 hours = 470 kW WOW, that is a very high power level, most homes use an average of .2 kW. My guess is that you mean you use 280 kW-hour in a year, which comes to an average power of .3 kW, typical. Assuming you get, worse case, 6 hours of sun per day, for the first case, 470 kW, each solar panel generates the equivalent of 250 x6/24 = 60 watts, so you would need 470k/60 = 8000 panels For the second case, .3 kw or 300 watts, divided by 60 that is about 20 panels. Depending on where you live, you could need as much as twice that number. Plus you need charge controller, lots of expensive batteries, and an inverter. The big problem is periods of no sun. If you demand continuous power, and you have a period of, say, 24 hours with no sun because of storms, etc, then the number of batteries increases to the hundreds.
Q:How many Watts of solar panels?
With an RV, you can find lithium bromide water chiller based refrigerators and air conditioner that run mostly on propane with just a little bit of electricity for a pump and fans. The oven, stove and heat, you can also run off propane. A Microwave is probably 750 watts but only operates for a few minutes at a time. You'll just have to go through everything item by item and figure out how many watts each one will draw and how long each will run per day to size your solar panel. Don't forget that the sun will only shine for a few hours each day. In general, for a camper, the target isn't to produce all the power you need but to slow down the drain on the battery bank to last till you get back onto the road where the engine can recharge the batteries. Keep in mind that the lithium bromide chiller systems only operate when stationary and level so some people opt for conventional electric systems just for convenience which sounds like what you're trying to do. Best way to figure out how much power each is drawing is by measuring it while in use. It may be worth it to put a meter on the battery bank and go camping one weekend with a generator or put a meter on the main circuit breaker panel and camp where power is provided, just to see what your typical use is. You're far better off running as much as possible from propane.
Q:Will my 8watt solar panel charge a car battery and how fast?
welcome to the wonderfull world of solar! you probably have a 2Vdc 8 Watt solar panel, to figure out its charging amps capability we do this equation Watts/Volts=Amps 8watts/2Vdc=.5Amps this is a conservative figure, since solar panel ratings are calculated using winter time sunlight, sunny locations and more daytime hours will give you higher amps. a typical good condition car battery is rated at 40Ah (Amp hours).to find out the charge time, we use the following formula; Amp Hours/Amps=T where T is time in hours 40Ah/.5A=26hours this is charge for a single battery, two batteries will double to over 52 hours. lets compare to charging a battery with your car, a car alternator puts out about 60 amps but usually run about half capacity. 40Ah/30amps=.3Hours! An alternator is far more efficient so charging with a small solar panel is best as an alternative or for low power applications. As far as using an inverter to power a TV, we can calculate how long the battery will last by using the original formula. a typical 9tv will use 70 watts 70watts/2Vdc=5.8A 40Ah/5.8A=6.9hours this figure is by drawing all the power from the battery, voltage inverters have a safety feature that will not let you discharge your battery all the way, so 40Ah battery will power a 9 tv for about 4.5 to 5 hours.
Q:Solar panel, Home office and Tax write off?
Pretty much stop existing.. Global Warming is Earth's way of pretty much saying..NEXT...We arent causing global warning its time for a change and the earth is doing it.. Mt St helens and also Mt Pinatubo put out more green house gases than anything humans did in history ..Its just a normal trend..Getting ready for the coming of another species.. just like it did with us and we survived ..that should be the question here ,how to survive the earths changes not what we can do about it. There is nothing we can do that will make a difference..Told Decaprio the same thing..
Q:How do you get electricity in a rainy day if you have solar panels?
Q:Where can i buy mini (v - 2v) solar panels?
I too want to buy the panels to light up my house.
Q:What are solar panels made of?
Solar panels are slabs of semi-conductor metal. Technically speaking, they are a slab of silicon semi-conductor doped or added with impurities to make it a better conductor. Solar panels could also be made of Gallium Arsenide which is a semi-conductor metal exclusively used in photo-voltaic cells.The silicon slabs are polished and glossed before doping. After processing, for protection, a thin glass layer is embossed on the solar cells slab. Silicon also is shiny and reflects about 35% of sunlight. Hence, an anti-reflective coating is usually applied over the slabs to reduce the amount of sunlight lost.
