Q:How to maintain a battery with a solar panel?
Yes, you can purchase a solar photovoltaic array to keep your batteries charged. You will need a Photovoltaic Cell Panel that produces 27 + watts (6volts x 4.5 amps = 27 watts) at 6 volts of electricity, a Charge Controller that allows only 4.5 amps of power through to the battery and will reduce the amps as the battery nears full charge and shut off the Panel when the battery is fully charged, and a 6v. Battery. Figure you will need a photovoltaic panel capable of producing a minimum of 27 watts if you are going to charge a completely dead 6 v. battery in one day. (with a clear sky). The way the system works is the sunlight strikes the cells on the panel and releases the excess electrons in the cells, they travel along central wires to your battery and charge the battery. When the sun sets, the procedure is reversed and the electrons flow backwards from the battery, into the photovoltaic cells. That is where the Charge Controller is needed. It acts a one way gate and lets the electrons go into the battery, but won't let them go backwards to the Panel. Just set your panel in the sun at the optimum angle for the season and your latitude on earth, connect the charge controller and then the battery, and it will keep your battery charged. Don't waste your money on the small wattage solar photovoltaic systems that claim to keep your battery charged. They simply can't do it unless your battery is in like new condition and is fully charged when they are hooked up. If you battery is a few months old, the small wattage photovoltaic systems can't keep up with the loss of power from sulfation inside the battery.

Q:H2 as an Alternative Fuel Source using Solar Panels?
Currently solar panels are rated at about 5 percent efficiency. That means that about 85 percent of the solar energy that is falling on it, is wasted. Electrolysis is also about 67 percent efficient. So the TOTAL amount of solar energy you would have converted into hydrogen is 67 percent of 5 percent. Using my calculator that comes out to: about 0 percent total efficiency. About 90 percent of your solar energy gets wasted in the process. A better alternative to solar panels would be solar powered sterling generators. Sterling engines are EXTERNAL COMBUSTION engines, like the old fashioned steam engine, and can be run off any heat source - including the sun. Heat from the sun is focused using parabolic mirrors, and the efficiency of a sterling engine / generator combination is rated at about 30 percent. Your TOTAL efficiency - both solar sterling and electrolysis combined - would be around 20 percent. If you are dead set on using hydrogen? Even though there are better alternatives? Such as alcohol? Then I would suggest storing it in titanium dioxide pellets. This way you can store the hydrogen, without it being in danger of exploding. You can ALSO ram a hydrogen container like this into a solid brick wall. Once again? Without fear of an explosion. Numerous studies have been conducted on this. As for controlling the exact measurements? Nothing in the air-fuel ratio of a car - - or the timing - which you are also going to have to change - needs to be exact. A good enough approximation will do. As for how you get your measurements? You need to compare the density of gasoline vapor with hydrogen gas. A comparison of the molecular weight of gasoline - - as compared to the molecular weight of hydrogen - should get you started in the right direction for this.
Q:Can someone please explain to me the basics of solar panels and power storage/usage?
I think the point you're trying to make is that solar electricity is more expensive than other means of mass produced electricity today, and I would agree. However, that doesn't mean that solar panels are not worthwhile, especially to a consumer in the right location. After the electric company adds in its distribution fees and profit, residential solar electric can actually be cheaper. And in fact, we have had panels on our roof for the past 5 years. Somewhere in the world, there's a factory producing AA batteries to use in flashlights, cameras, and so forth. I'm certain the factory does not run off AA batteries, yet I find AA batteries invaluable for certain things around the house.
Q:know about solar panels?
Solar Panels are groups of Solar Modules mounted together. A solar cell is one cell. A solar module is a group of cells mounted in to a sheet A solar panel is a group of solar modules connected together on a rack and normally placed on the roof etc.. as a unit and can be called a solar array. A solar array is a group of solar modules or solar panels all mounted and wired together to form a single unit. Like a battery bank is a bunch of batteries hooked together and the batteries are made of cells. Was that what you wanted to know?
Q:Solar panel for your home?
The first thing to understand is that there is nothing complex about a solar panel. It is nothing more than a collection of solar or PV cells on a board that is fitted to the most appropriate part of your home, generally on the roof. There are guides out there that teach you how to build a solar panel and a windmill for just $50, and it’s very easy to make. Best of all, you can save 70% or more on your energy bill, adding up to thousands of dollars each year in savings. I reviewed both free guides and paid guides and have come up with our top to Build your own solar panels.
Q:if you put solar panels on cars, you'll be able to drive without gas in the summer and part of winter?
Yes. But you won't be able to go very fast. If you fill up the roof, hood and trunk lid of for example, a Toyota corolla, with the most efficient solar panels you can buy, you might get 2 hp in the mid day sun. That could push the car maybe 2 mph on a flat, and wouldn't get it up a hill unless it had super low gearing. In order to go fast enough on solar power to make it worth while, you need a large area of solar panels and a super light car. Like an aluminum tube frame with a foam and fiberglass composite body, skinny, high pressure tires and a solar array 6 ft wide by 2 feet long. A car like that, with good aerodynamics and a 6 hp motor could get up to 45 mph eventually, just slowly. But it's impractical because it's not safe to drive it with other cars around. But who says the panels have to be on the car? If you have a solar array that feeds as much power into the grid as you take out, that is essentially equal to being solar powered in all practical ways. Even if your car can't be entirely solar powered, that don't mean you shouldn't use solar panels. You could use solar panels in any car, to supplement battery charging, taking load off the alternator, and you would see an increase in fuel economy. There is a system on some cars that uses solar power to circulate air through the cabin when the car is sitting in the sun. This keeps the car up to 30 degrees cooler, taking a huge load off the air conditioner, so instead of pumping all that heat out, you simply vent it into the air, and there is an increase in fuel economy for a few minutes. Every little bit counts.
Q:How does a solar panel charge controller work for batteries?
In digital circuitry almst anything is viable. Virtually. The changing of voltages and currents is most of the time viable however not constantly effective. Sure it is extremely easy to make use of the 24 volt energy panel to charge a 2V financial institution, offered that the 24 volt supply has the fundamental current potential to hande the load.
Q:how can i build my own, cheap, solar panels at home?
The idea behind building your own was to get defective and broken solar cells from the manufacturer, preferably for free though many now charge for them. These are cells that are either cosmetically blemished, cracked or otherwise broken during manufacturing and transportation. As each cell fragment could have very different voltage and current characteristics, you have to manually measure the voltage and current characteristics, sort them and then wire them in parallel or in serial to achieve the desired voltage and current characteristics for the panel. Wiring in parallel increases the current while wiring in series increases the voltage, the current capacity of cells in series will be that of the lowest current capacity cell in that series hence you need to match fragments up to wire in parallel till you have enough current capacity to participate as a cell in the series. Cell fragments can only be wired in parallel if they have the same voltage output. It's painstaking work and it's difficult to place all the irregular shaped cells onto the solar panel in a layout that efficiently uses the space so your solar panels will likely be much larger than commercial ones. You could augment them with Fresnel lenses since the cells don't occupy as much of the available surface area hence focusing the light onto the cells rather than the board will help with efficiency. Practice your soldering skills cause you don't want to have to go back in to figure out where that cold solder joint is. If you're real lucky you can get a supply of blemished cells but the cheapest ones are the broken cells.
