To answer this question the output current and voltage of the solar panel would be needed.
No, a 12-volt charger cannot charge a 36-volt battery. The electrical potential difference across the leads of a charger must exceed the electrical potential difference across the terminals of any battery it is expected to charge. And 12 volts is much less than 36 volts.WHY?The 36-volt battery would require at least 39.3 volts to get to a float charge. This would charge the battery to 80% quickly, and then take a logarithmic period of time to finish the battery. To actually charge the 36-volt battery correctly would require roughly 43.2 volts, but if we can't get 39, this is irrelevant.The 12-volt charger has no chance.The answer above is correct; there is no way the 12-volt charger can charge a 36-volt battery. However, the voltages given apply only to lead-acid batteries. They would be different for nickel metal hydride or lithium cells. You still need a charger with more voltage that the battery voltage in any case.
A solar cell does not store electricity. It charges a battery that stores electricity. The voltage of a battery can be found by connecting a voltmeter to the battery terminals.
I do not think so. There is not much sun at the noth pole is there? And the, solar panel would not get much energy would it?
Well, that really depends on the type of panel used. More than likely you are going to need a voltage converter in between your panel and your battery. This converter is a switching powersupply, and takes the nominal voltage of your panel and steps it up/down to the correct voltage for your battery. Switchers have the advantage of being able to take a certain amount of power and turn it into a fixed voltage output. The design of the supply sets the input voltage range, but it can swing across several hundred volt range if designed properly. This is important for one main reason: solar cells have what is called an IV curve. You plot voltage against current for your panel and it shows a nice curve with a bend at high V/I levels. At a specific point on this curve, where V and I are both maximized, is the Maximum Power Point. This is the voltage and current where you get the most power off your panel. Some converters are smart and find this point. They are called Maximum Power Point Trackers or MPPTs. They will draw as much power as possible out of your panel for you to use. The Biel school of Engineering makes some that work well, but they are not cheap. I believe Xantrex technologies makes some as well. I've only played with the Biel's during my tenure on the ISU Solar Car Team. Other converters do not track. They just draw at a certain power level, and if it's not the max so be it. They are the cheaper of the two types. If this is a home panel this type of converter is a viable option as you can set the maximum power output to your battery. Since you don't want to overcharge your battery, the unused potential power from your supply is kind of a wash. Finally, you may be thinking "Well, why don't I just hook it up directly?" Good question. Firstly, if the maximum output voltage of the panel is too high, it can damage the battery. If the maximum output voltage is too low, it will never fully charge your battery. If the voltage output of the panel is less than the battery voltage (Low light), your battery will not charge. This set up will take a long time to fully charge your battery as you are on the high voltage side of the IV curve. The converter eliminates all this by taking a certain amount of power (voltage independant) from the panel and converting it to the correct charge levels for the battery. You will have to research this, as you need to match your converter to your project and panel. Take a look at Xantrex technologies, I believe they make setups for this exact project. Also, if you plan to drive your home with this be sure to talk to your power company. They will tell you how to do it safely, and, if your system is big enough, may let you sell power back onto the grid. Good luck.
yes it just takes longer to charge, but check how much Amps (A) your charger gives out and how much Amps your battery can take if the battery has lower Amperage (A), don't do it, otherwise you're fine. <<>> No, the charging unit has to have a higher output that the battery voltage that it is charging. For example, on a 12 volt car battery the charging rate is 13.5 volts.
A few variables are involved like, does the solar panel have a charge controller, what condition the battery is before you start and how much sun is the solar panel receiving.
about 500watts/meters of irradiance
A very long time. I would guess 48 hours of sunlight at the very least. Even that may not be enough to fully charge the battery. It really depends on how much amperage the solar panel is putting out.
Most likely not. In order to charge the battery to its nominal rated 4.8 volts, youreally need a source capable of more than 4.8 volts open-circuit.You need to take the solar panel and a voltmeter, and measure the output voltageof the solar panel with no load connected to it. If it's more than 4.8 volts, then itwill charge your battery.But . . .That's not saying anything about how long it will take. 0.4 watt is not an awful lotof power, and your solar panel will not even deliver that much before its outputvoltage sags to 4.8 . So I would think that this solar panel will not be an acceptablecharger for that battery.
It depends on the size of the solar panel and how well built the product is and the energy holding capacity of the battery.
A very, very, long time. Only a guess but I would venture to say at least 15 hours.
not much.
There is too much information there. Charging a 100 amp-hour battery fully would take 18 hours at 5.5 amps, or 6 hours at 16.67 amps. At 5.5 amps the power would be 12x5.5 or 66 watts, and this is the rating of the solar panel required. That would be about 0.4 of a square metre.

There are no solar car batteries you can buy. You can purchase a solar battery charger and solar panels but not a solar battery that you install in a vehicle.
The cost depends on how high up the solar cells are, how much risk of falling and how much safety equipment is needed, and whether special cleaners are required. An equivalent service is window cleaning. Charge as much as those in the area charge per window on a second story.
depends on the size of the solar panel and the weather. the bigger the solar panel and sunny weather will generate more electricity
