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:Solar panel connectionI
The answer is that the two panels should be put in parallel. The voltage out will drop to the voltage of the lower panel, but you should get most of the power, if the panels aren't too badly mismatched. I would try to get a multimeter and try to measure the actual current coming out of the panels in full sun. Sometimes the specifications on these smaller panels are very optimistic. If the whole setup is putting out less than 2 amps, I'd say wire the whole thing straight to the battery - little chance of boiling the electrolyte at those currents.
Q:Solar panels and distance from the sun?
There will be a difference (44%, see below) but not a large one. The atmosphere is transparent to the wavelengths used by the solar panel. But no clouds, and a lot more hours of sunlight. wikipedia: Space-based solar power (SBSP) (or historically space solar power- SSP) is a system for the collection of solar power in space, for use on Earth. SBSP differs from the usual method of solar power collection in that the solar panels used to collect the energy would reside on a satellite in orbit, often referred to as a solar power satellite (SPS), rather than on Earth's surface. In space, collection of the Sun's energy is unaffected by the day/night cycle, weather, seasons, or the filtering effect of Earth's atmospheric gases.
Q:Best orientation for my solar panel?
It doesn't make sense to me. I am at latitude 37.7,and my panels face south at about 38 degrees. Yours should be pointed north as you suggest. Being so close to the equator, and in the absence of any better information, an angle of 2 degrees would be appropriate. However, choosing the best angle will greatly to your overall efficiency, so I would try to find a more credible source, How about the folks from whom you buy the panels. They would know precisely. By the way, if you haven't installed the system yet you might consider going to a high voltage system to cut known line losses in the conductors between the panes and the inverter, I did that plus increasing the conductor size over that recommended by the manufacturer. I gained about two percent in efficiency

Q:how do solar photovoltaic panels work?
Hey E Girl, photovoltiac panels are pretty simple. They start with a solid block of silicone, and shave thin layers off of them, called wafers. Once you have about 72 of them, you take half of them and dope them with boron, then the other half are doped with phosphorous. Once that's done, they take one each phosphorous and boron wafer, and glue them together with a special conductive epoxy glue, and attach a wire to each wafer. When the two glued wafers are exposed to the sun, a reaction occurs that forces free electrons from the silicone particles from one wafer onto the other, and a voltage is generated between them, about /2 volt to be exact. Once all 36 pairs are glued together, they are wired in series, connecting the phosphourous wafer from one to the boron wafer on the next, and so on. If you start with 72 wafers, you'll have 36 pairs glued together when you are done. At /2 volt each, that makes a 8 volt panel, which is used to charge a 2 volt battery. The charging source always has to have a few more volts than the battery. These 36 pairs of cells are then arranged on some kind of back board, glued down, covered with acrylic glass and mounted in a frame. There are some great websites you can go to for more info, I will list some below. Did you know that there are over 00,000 homes and businesses in the US alone that use some level of solar power to operate their electrical systems? That's good news. We actually live in one of those homes, it is powered by both the wind and sun and heated with solar and wood. I hope this answers your question, good luck, and take care, Rudydoo
Q:I need help with a solar panel?
You not only need a diode, but a circuit that opens the circuit if the voltage falls below a certain level. The diode is not the problem, but the batteries powering the solar panel when the voltage falls to low.
Q:How many wind turbines and solar panels does the world need to replace coal, oil and nuclear power?
Both the wind turbines ( windmills) and solar panels are less costly to implement than nuclear power and have less disaster potential. They have proven that Windmills miles out in the ocean are a great source of power. This dose not consume any land. For land bound areas they should use public roadways to line the windmills. For areas without sustainable winds they can use the combined effect of windmills and solar power. Honey, any motor needs oil. Whether it is a generator for a windmill or a nuclear reactor. Motors are what runs the world. Consider the amount of oil to run a nuclear facility. Tons more than a generator motor. Once a turbine is activated (motor started) the winds themselves turns the windmill. Each turbine is lined up with the next (wind farms) to push wind at the blades, they each push each other.

Q:How much do solar panels cost?
Solar panels typically cost in the range of 8 to 0 dollars per kilowatt of power they are capable of providing. That same kilowatt of power costs in the range of 8 to 0 cents normally. This is the reason solar is not all that viable, without government incentives. The person who responded You're looking at $0,000 to $40,000... is so far off the real answer as to not even be funny. I suspect a solar pv system for a school would start in the $400,000 to $500,000 range. Many areas though have incentives, which will reduce the actual out of pocket costs (but not to $0k).
