Q:how much watts can a x2 inch solar panel make?
this type of solar panel has some few watts. Ah is a quantity (which represent energy) that define the flow of ampere for a period of hour. so, the max instant electric current is 40mA and the max power is 40mA x 3.6 = 0.44 watts but, this value depends of the solar ilumination which the panel is subjected.
Q:how much power do i need from my solar panels?
Complex question.... Let me try to simplify it some: Make a list of every electrical device you MUST have. Add to the list how many hours a day it is actually ON. Add to the list how many watts (listed on the label or Volts times Amps) the device uses. (If you have a measuring device, use it.) For each item, multiply volts times hours = watt-hours (this is total energy used per day). Also, add the watts column for all the devices (this is the maximum instantaneous power to be used). Your solar panels should be able to provide power for your total load, so your panel's output power should equal the maximum instantaneous power used. If you can limit how many devices are used at a time, you may be able to reduce the panel size. Look at the total watt-hours. This is the total energy. Your panels generate maximum output when they are perpendicular to the sun at noon on a clear day. They generate reduced output in the morning and afternoon. They also generate substantially reduced output on cloudy days. Also, did you want electricity at night? On cloudy days? You will need batteries.. lots of batteries. And batteries are inefficient.. figure about 50% efficiency after a few years. Basically, here is a very rough formula: Panel_watts = Load_watthours / hours_sun_daily / 60%_angle_efficiency / 50%_battery_inverter_efficiency Once you've figured out the panel's watts, watts/volts=amps. Your system can be 2V with more amps, or 48V with /4 the amps... but the watts are the same. Just the wiring is different. For the battery bank, you need to determine how much backup power you will need for nights and cloudy days. Look at the watt-hours needed at nite, multiply it by the number of days and then by 2, to allow for battery aging. Unless you only have a couple devices and an LED light or 2, it is going to be VERY expensive.
Q:How do you set up 30w solar panel?
With a 30 watt panel, producing about 2 amps, your not going to have much power from that. A 22 AH battery will give you 2 AH of usage. A battery should never be drained below 50%. What this works out to be is simply Amp draw for 2 hours. Which equals to 2V light bulb that draws amp for 2 hours. Not much. Now to replace that usage with your 30 watt panel, provided the panel is clean and in max sunlight, it will take 6 hours. If you attach an inverter to your system for 5 Volt Usage then the DC voltage drawn from the battery is very high. Example: Say you use a 5 Volt component that requires 50 Watts per hour to operate. The inverter will draw 5 Amps out of the Battery every hour to operate that component. That gives you and /2 of use before the battery is down to 50%.. Maybe that will be enough to charge up a standard Laptop battery. I have 2 30 Watt panels that produce 5 Amps, 4 6V batteries that have 480 AH and a 25 Amp Controller with a booster that increase the amp output to 20 Amps per hour. I live full time in an RV and raise the panels to get max output when I am parked. This system provides me with all the 5V throught the 500 Watt inverter that I need. Good luck on you system.
Q:How to build solar panels?
I am not sure about that book, but most places tell you what those solar panels are built out of, as far as getting the materials you will probably need a state tax permit since most manufacturing companies usually only sell to other businesses. I went to their website and their claims sound a little outrageous. Just to build a windmill which is usually cheaper (and if you live in a windy place more efficient) you would spend much more than their claimed 200, since you would basically be making something that almost looks like a motor but works backwards, and you would need more than one. Now can you build a 0,000 dollar worth system for 3000, possibly, but again you would need a good understanding of how it works in order to put it together yourself. You can always get the book and see for yourself, but usually I shy away from outrageous claims. Good luck.
Q:any one know about electricity solar panels?
The charger will accept whatever current is necessary from the solar panel up to 7A. It's not like the solar panel will force 2amps into the charger/battery -- the charger will control the current going to the battery. I question whether or not the 2V panel will actually charge the battery, though, because in order to charge a standard lead-acid 2V battery you need to have about 4.5 volts applied to the terminals. Perhaps the charger has a boost circuit -- I don't know without looking at it or knowing the brand/model number, etc. The timer must be 2VDC, but, if you only have a timer that is rated for 20VAC, you can buy a small inverter that will take 2V and supply the necessary 20VAC. An inverter rated for 20 to 50 Watts should be sufficient. These usually cost under US$25. .
Q:Can you make a solar panel shift sideways?
having solar panels move like that on a mobile platform is inadvisable -- especially if there is a dynamic wind load resulting from the motion of the mobile platform. Even having a tilt mechanism is dubious at best. think of what limited marginal gain would be gained by mounting a small solar panel on the moon roof of a car. (ultimately, the best answer is to turn the car so that it's angle to the sun is optimal -- but the road/travel direction constraints are what ultimately prohibit that.) while there are ways to build sliding panels, the weight constraints would interfere with your weight/thrust ratios to the point of futility. if you really need that panel somewhere else, don't slide it out of the way, just buy another panel and mount it there. it's more expensive, but it's actually the cheapest solution in terms of design on a mobile platform.
Q:solar panels and calculations?
The The reference section has all the formulas you are looking for and there is a list of dealers by state, plus various state rebate information. Yes, you can hook up different panels to the same system. There are special controllers that regulate the voltage. I'm more of a hands on nuts and bolts guy so I can't help you with the formulas and engineering explanations. Another great place to get information is Home Power Magazine. You can get the issues online or in print. Thanks for going solar!
Q:Why are solar panels effected by operating temperature?
Absolutely temperature matters. So what do higher temperatures do to solar photovoltaic panels? As temperatures rise, the efficiency of solar panels decreases. Heat causes electrical resistance to the flow of electrons. On days where the temperature is more than 75 degrees, the electrical resistance makes the voltage fall thereby producing less kilowatts per hour. Your roof is much hotter than temperatures on the ground. That’s why solar panels are not mounted flat to a roof. There’s usually a few inches of spaces between the panels and roof so air flow can easily pass through and cool the panels down. There are some photovoltaic panels that are designed specifically to operate in hotter temperatures. These panels have a higher temperature coefficient. This is especially important in high heat climates like Arizona or New Mexico, but probably wouldn’t make too much of a difference in New England (except maybe this year). If someone lives in one of these areas, they should speak to a solar installer to make sure they are using they right equipment for their region. Please note: Solar thermal panels used to heat water can withstand high temperatures without any degradation. In fact, hotter temperatures would actually be better for these types of modules.
Q:what materials would you use and how would you construct solar panels enough to run a household?
If you think that a solar storm is going to knock out most power utilities in that time, what makes you think that your solar panels will not be affected as well? The cost to even come close to light up half your house will be prohibitive and will take at least a decade or 2 to just break even on your original costs. May want to do a little more research on your 202 storms. If you are concerned about the power going out for a while, then you better check at what else may happen.
