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:Why are solar panels made from silicon and not magnesium?
Si is a neutral semiconductor, and, when combined with the other metals in the solar panel, it the panel polarizes, and releases electrons form one end, and accepts them back at the other. Like a water pump. Mg is not the major ingredient because it doesn't have the easily altered semiconductor properties Si does. To put it simply, Si is easier to work with.
Q:The effect of colored light on a solar panel?
It is based on what the solar panel is made out of. Many of them will generate electric into the NIR region.
Q:who knows about tax credits for solar panels?
If you buy NEW solar panels, there is a credit. see the 040 icon at www.okorder.com
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 System at Harbor Freight?
i wouldn't. - harbor freight isn't known for the best quality stuff. - 75 watts assumes roof mounting, at 90 degrees to the sun, on a bright day. you're going to get considerably less. and only when the sun is highest in the sky. maybe you should look at, your computer, for example. if you're using it for 4 hours, and it has a 500 watt power supply, and you add 200-500 watts for the monitor, and some for the printer, modem, etc, you'd use 5kw that day. your 75 watt panel, generating maybe 50 watts at most, for maybe 4 hours when the sun was highest, and shining directly on the panel, would generate 200 watt hours. it would take 25 days to generate the electricity you'd use in single day. in the winter, you'd be pretty much out of luck. there just isn't enough bright sun. clearly, it's up to you, but there's a harbor freight near me, and i'll not be rushing out to get such a system. further, most appliances are quite voltage sensitive. you really do need to have the voltage in the 0-20 range. too much out, either higher or lower, will shorten the life of appliances at best.
Q:how to store energy from solar panels?
If you are buying a kit, chances are there is an instruction manual in there on how to mount your solar panels. You can also ask for assistance from the store.
Q:Do solar panels make electricity from light intensity or watts?
Have okorder.com . It might surely benefit anyone!
Q:If I shine different color lights (bulbs) on a solar panel, will it affect the electricity output?
