Wiring

To ensure proper system operation to maintain your warranty, observe the correct cable connection polarity(Figures 1&2) when connecting the modules to a battery or to other modules. If not connected correctly, the bypass diode could be destroyed.

PV modules can be wired in series to increase voltage. Connect wires from the positive terminal of one module to the negative of the next module. Figure shows modules connected in series .

Q:Does making solar panels cause more pollution than they take away when used?
A study by the US Department of Energy shows that, depending on your solar panels, the energy payback is to 4 years. Solar panels usually last 25 years, so solar manufacturing is very green. That said, if you buy American made panels, it saves more carbon from the transport costs. Something to consider in choosing your panels.Actually, most panel manufacturers will recycle the panels after you’re through in 25 years. If they don’t, don’t buy those panels. However, it’s hard to say whether people will actually recycle them because most panels are still being used today. So it’s up to you find out about the manufacturer’s panel recycling program. From what I understand, they will come to you and take them away at no charge.
Q:how to make a solar panel without any kit?

Q:Solar panel, Home office and Tax write off?
5% of the Net Cost (After Rebates) Depreciated over 27.5 years. EDIT: Oops ....39 years. I was actually debated that in my head before I posted.
Q:solar panel inverters?
Stand Alone solar panel inverters function to change direct current (DC) from a battery to Alternating Current (AC). Stand alone inverters, which range from around 00 watts to as much as 8000 watts, are used to power a vast variety of personal or small business projects. Lower watt stand-alone inverters are often used to power laptop computers, whereas high-watt stand-alone inverters could be used to help power an entire household. In order to calculate what class of inverter you need for use with your solar panel, you will first have to determine the maximum sum of all of the Alternating Current loads in your project (or home). How to calculate the wattage you need from your stand-alone solar panel inverter
Q:Solar panels?
Yes of course there are.powerful solar panels for camping can generate up to 60 watts of energy which would be enough to charge phones and keep the lights on for a night.you can also get small phone sized solar panels for charging mobiles and torches. Check out the list below----
Q:Is it truE thet solar panels. . ?
You do not need batteries unless you want power at night, you don't need a regulator unless you'll be using your panels to power anything other then what the voltage of the panels is (ie 2v panel = 2v llight bulb) 3.You can use them directly or you can use car batteries (though deep cycle batteries are better).
Q:Could solar panels contribute to global warming?
As far as any albedo effects from solar panels, the entire USA only occupies a little over 2% of the worlds surface, if you painted the USA black, it would have a minimal effect on globally averaged temperatures. The mining of the resources alone required to cover the entire USA with solar panels would devastate the planets ecosystem. . .
Q:How do solar panels and their battery backup systems work?
Solar panels have their own characteristics and generate current depending on the intensity of sunlight falling on them and not on the temperature. Direction of the panel also makes lots of difference. Nowadays very thin panels are available at very high cost. The more area a panel occupies it generates more current. The current generated by a panel cannot be readily used since the current and voltage varies with the load connected to it. So normally a regulator is used to have constant voltage and constant current to come from the panel. This charges the battery. You have to calculate the total/normal current from the charger and then find the AH of the battery. When you have calculated the AH of the panel/charger then you can divide the AH of the battery by the AH of the charger/panel and find out the time taken to fully charge the battery. You also have to remember that there is a de-rating factor to be taken into consideration in the battery.
Q:How to select solar panel for this application?
Be aware that you cannot discharge the full capacity of a lead-acid battery without destroying the battery. With a normal battery of this type, you would only want to discharge about 20%, so you would need a 70 AH battery bank. For the 3-day requirement, 500 AH. This is still within reason. If you didn't have the 3-day requirement, you might consider going with NiMH batteries. Back to the 500 AH bank, you would usually charge at at least 5% C, or 25 amps. At the 5 volts that you need for charging, this is 375 watts. Possibly you could go as low as 200 watts.
Q:What kind of Solar Power panel setup do I need for this?
Unfortunately solar panels are low output,generally only 2 volt and very low amperage,so you would need to build a multi panel array with a DC-AC converter all together costing several hundred dollars which would only work during sunlight.Just roughly figuring,about $800. Plan2-Solar charger,battery bank,and DC-AC inverter so it would work 24hrs a day,also several hundred $$. Solar power does just not seem feasible(to me)in this application.By far the cheapest set up here would be an extension cord fromhouse to the bucket.260 watts per hr is a fairly lightweight draw,even not figuring the thermostat's cycling it on and off as needed.Electricity is sold in kilowatt hours(000W/hr).This bucket would use(not allowing for thermostats control lowering it)appx 6000watts or 6KW per day.Depending on your electrical cost per Kwh it would cost very little to run.(In my location appx 50cents a day) or appx the same amount as my computer(325watts total)) Note that that would be a maximum rate,and would actually be less due to thermostat cycling off and on as needed.
