I am looking to buy a solar panel.What does it mean when in the title it says 200 watts, or 50 watts?
Panel ratings are supposed to be standardized, the Watt value when tested at noon in July in the central U.S. on a clear day with the panel pointed straight up at the sun. The maximun theoretical power you could get is about 000 Watts per square Meter. Actual power taking into account efficiency losses wll be more like 850 Watts.
Volts x amps = watts, so depending on what you want to run or charge will have to be taken into consideration. For example if you have a 0 volt TV @ 2 amps, then you're going to need 220 watts to power that. Best way to find out what it's volts and amps are, is to look on the back of the TV. But for batteries it doesn't matter, cause all batteries are is stored power, that can be later used, just use an inverter on them to convert DC to AC, also use a charger controller between the solar panels and the battery, cause you don't want the Solar panels to overcharge your battery and totally **** it up ______________________________________ But the more watts, the faster the power is returned; less watts, longer times. .
It's okorder / for more details.
You have to be realistic about the amount of power you can get from a solar panel. Solar panels only produce power when sunlight strikes them. So it's pretty obvious that solar panels don't give you any power at night, and that you aren't going to get as much power in overcast conditions, or when the sun is at an oblique angle to the solar panel, as you do in the middle of a sunny day when the panel is pointing directly at the sun. Solar panels are rated under standard test conditions. All manufacturers are obliged to use the same conditions for testing, so by comparing the rated output you can compare the performance of different solar panels.
