Q:Properties of solar panel?
Q:how to know the voltage level of solar panel?

Q:will a 5v 52watt solar panel charge four 2c dv 55ah batteries?
Technically, any solar panel can charge any battery, but it would take quite a long time do do so if it is a large battery. If you are aware of the voltage and either amp or watt rating of the unit that is usually used to charge the battery, the solar panel should have a similar power output to that charger to work well. amps and watts are quite similar, and can be converted with this simple formula: W=watts; V=volts; A=amps; W/V=A; V*A=W; When charging batteries, it is always wise to use less amps than needed, and roughly the same voltage as the battery being charged. The less amps used to charge batteries means the battery will take longer to charge but will last a lot longer in the long-term. Your solar panel should be sufficient to charge the battery, but you should test charge it to see if it works well. I recommend using a multimeter to check the batteries voltage every couple of hours. Once the battery reaches 2v, it should be fully charged. You should also check the amps in case they are not at the expected value (take caution when checking amps with a multimeter, when i do it i always end up melting my multimeter leads). The battery should be fully charged from anywhere between 6-48 hours. if it is charging faster, the solar panel has too much power. if it doesn't charge in this time frame, the solar panel is not powerful enough.
Q:Self build solar panel ?
Sure it is possible. There are even commercial products that do that. I have a solar cell phone charger. But it is not able to fully charge the phone battery. I am not sure why but I suspect the voltage it puts out is too low. In other words, it is a poor design. It is certainly possible to make a better design, but maybe not easy. You can damage a battery by over charging it, so just increasing the voltage is not the solution. You need just the right voltage and current.
Q:How do you install solar panels?
You need to determine how many solar panels will produce the amount of power that you consume now. You can check your bill for the number of kilowatt hours (power) you will need. There are websites that will help you calculate the intensity of sunlight in your area. There are other websites that will help you determine the average daily sunlight. The sf of your house has no importance. The amount of power you use is independent of the size of your house. You hook up solar cells in series to increase voltage. You hook up solar cells in parallel to increase current. Power is voltage multiplied by current. Most modern houses are supplied with 200 Amp service at 240 volts AC. The solar panels produce DC power. The grid in most places provides AC power. So you will need a AC/DC power converter. The sun does not always shine so you will need a storage battery bank capable of storing all the power you will use at night.
Q:Does infrared radition occur in solar panels?
- Radiation from the sun is mostly Ultra- Violet. - There are 2 types of solar panels, Solar thermal collectors and photovoltaic cells. - Put simply, photovoltaic cells take the UV rays and produce electricity. - Solar thermal collectors (which is probabl
Q:Are solar Panels worth it?
“Where you have good (sunlight) and access to financing and a combination of federal and state incentives, you have a number of markets around the country that are very vibrant, and it’s very cost-effective with financial paybacks in the order of five and 0 years,” said Robert Margolis, a senior energy analyst at National Renewable Energy Laboratory (NREL).
Q:how often do you have to replace solar panels?
Expect a water heating panel to last about the same as a water heater, 0 to 5 years. Actually, my brother's system is coming up on 5 years, and is not giving trouble yet, so maybe technology has advanced. I have actually never personally known of anyone replacing a solar electric panel due to wear-out. I have heard of occasional replacements due to accidents, including natural disasters like lightning strikes. And one brand of panels had manufacturing defects around the year 2000, but that manufacturer owned up and replaced those free of charge to their customers. A standard warranty on a solar electric panel nowadays is 25 years.

Q:where to buy solar panels?
theres a sparkling technology of solor voltaic cellular popping out in 2009 which will diliver 40% greater potential than the regular living house use cellular panels, they'd cost as much as they do on the instant purchase at 40% greater its properly actual worth the wait, plus the advancements being made in case you do diside to make investments they are going to be obsolite in 5-0 years yet by potential of then the device could have paid for them selves, which in time they do. and in case you get a slow wind, like we do right here in northen indiana, get a wind turbine rated at 7k in line with day
