Q:Are solar panels efficiency already calculated in their power rate?
If it says STC or Standard Test Conditions on the nameplate or documentation, then that means 80 watts under bright sun at an unrealistically cool temperature. It is rare to see that power in real life, except when the perfect storm of conditions come together. There is also a PTC rating for some panels, which is more realistic. If the panel does not say STC or PTC, the manufacturer is free to make up whatever test they feel like, which generally leads to ridiculously overstated power. As for efficiency, for residential panels, that's generally only of academic interest. A 80-watt panel is 80 watts, regardless of the efficiency. A more efficient panel will take up slightly less space, but most people are more interested in the total price, since roof space is generally not an issue.
Q:Computation of Solar panel requirement?
The power output of a solar panel uses a formula to determine kilowatts produced per hour per square meter per day. This calculation is important because, if you plan to install a solar power system for your home, you will want to know how many solar panels will be needed. To calculate solar power requirements correctly, you need to gather the data that is needed for the calculation. First you have to find the average amount of solar radiation available for your area. You can use a solar radiation chart. This can range from a 4 to a 7 depending on the area you live in. Write the number down on a piece of paper and indicate it with the letters RA. Next is determine the amount of electricity that you use daily. Add the kilowatt-hours used per month from your utility bill. Multiply this number by ,000 to get the watt hours in a month. Divide the total by 30 for the amount of electricity you use daily. Write this number down and indicate it with the letters DE. Determine the percentage of your home that you want to power with the solar power system. Write this number down and indicate it with the letter P. Determine the system inefficiency factor for the solar power system. You should be able to find this on the brochure for the system or from the manufacturer's web site. Write this number down and indicate it by the letter I. Determine the power or yield that is required for your home. Use the equation P = I x (DE x P) / RA to find the power requirements in kWh. Divide the number from Step 5 by the peak wattage for a single solar panel to determine the number of panels you will need for your home. Goodluck! :)
Q:Powering my house with solar panels?
We are installing a 3.3 kWh system on a 2 story house. Really three story if you add in the basement. It will provide about 3/4 of the electric power they use per year. The cost of the complete system installed is in the $26,000 range. A 4.5 kWh system would wipe out their bill and would cost in the $34,000 range installed. But it had too many solar modules to fit on the roof. Now if you are wanting to go off grid in the average American home you would spend about $60,000 easy. Most American family's are very very waste full. Very few even have CFL lighting and leave every light in the house on. I have even known of some that will use a 60 watt night light when it is so easy to put in a CFL or a 4 watt night light. With 4 TV sets running in most homes at the same time a 200 watt stereo system for background noise.. Well we Americans have a long ways to go yet.
Q:who would win in this battle?
hmmmmm trees would squash em and solar pannels would electric cute em............... :)
Q:What specification of solar panel do I need?
Ive been employing the comparable photograph voltaic panels for 5 years, have flow some instances so as that they final lots longer than the roofs weve had over us. i'm coaching my young ones a thank you to construct wind turbines, because of the fact we shop having potential failiures whilst the wind blows. and recently its have been given very windy. I can charge banks of battery's and shop my place of work working from dc-ac converters.
Q:I have two ARCO M55 solar panels. What do I need to connect to a 2Volt bank of batteries.?
This Site Might Help You. RE: I have two ARCO M55 solar panels. What do I need to connect to a 2Volt bank of batteries.? Do I need some type of regulator when the batteries are fully charged.? The Arco Panels voltage is approx 7VDC at 2.5 amps, Should I limited the voltage to 4VDC??. I would like to connect both panels to up to five batteries at one time...??
Q:Solar Panels heat absorption?
Solar photovoltaics require light, any kind of light. A torch would work, for example. The effect of concentration depends on the amount of light and the material you're shining it on. In CdTe, warmer temperatures and more intense light may lead to better performance. In silicon I think the opposite is true (I don't know though, I've only done research work with CdTe). It depends on properties of the semiconductor, like its band structure. To get an 'order of magnitude' estimate, you may assume a constant efficiency of solar cell so total amount of light (= area * intensity) largely determines the output in standard operating conditions.
Q:Solar panels require big initial investment, how can I check if the money I save will be more than that?
you have a really good formula for figuring out what you will save. as long as you dont live the the arctic during the winter months you should be fine! this investment will definitely pay off in the long run and help the environment. just like the other guy said, the utility company would have to pay you back any excess energy you produce that you dont use! you can calculate how much your average electric bill is and then compare by how much you would be saving. you can multiply the number by 5 and 0 years and so on to see how much you would save ultimately! this is a great way to save your own money and never have to be dependent on the electric company again! yes you will definitely need a battery to hold a charge for overnight use good luck!
Q:how to design a solar panel to store energy and convert it into electrical energy?
solar panels are designed to charge 2v batteries, now depending on the power you need you can determine what kind to use there are many power ratings for the modules, for example if you want to charge two 2v batteries you can connect them in parallel, if you want to reduce the charging time you can use more than one module in parallel to increase the power.
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.
