It is not based on the area really...
basically for each photo voltaic cell they have a certain voltage, if you connect them in series such as
-------0-------0----------0---------0--- then it will increase the voltage 4fold but not the amplitude
if they are connected in parallel then amplitude will increase but not voltage. Usually panels have a mix of both to get a good voltage and amplitude

Why photovoltaic street lighting system is not recommended for urban area?
for pv street lighting solar panel, battery is required and also maintain-ans. we can not provide that much facility to urban area. because this equipment are so costly .
How does sunlight intensity and the surface area of a solar cell affect it's electrical power output?
The larger the area surface of the solar cell the more energy output is made, because of it has more area so that it can intake more sunlight so therefore it can give more of its energy of more quickly.Most obviously the more sunlight intensity on the solar cell the more energy it given off because sunlight = energyso the more sunlight that has been inputed into the solar cell the more output energy will be given off.
Does the output voltage of a solar cell depend upon the area of its surface exposed to the light?
yes, along with many other factors. Solar cells use the ultraviolet band of energy from a light source above the other bands. This is why incandescent lights do not provide as much power as a florescent lamp or why solar panels use quartz instead of glass covers.
What is a solar photovoltaic - PV - panel?
A PV panel is a Photovoltaic conversion tool used for converting the sun's rays into usable electricity via an excitement of Protons and Electrons in a solar cell. They are typically 3ftx6ft in size.a solar panel is a energy converterA solar panel converts the suns rays into electricity.Solar panels area group of 36 solar cells arranged on a board to produce a level of usable power. Each cell produces just under 1 vdc. Ganging these up into a set of 36 allows the system to produce around 12 to 15 vdc. This allows the charging of a car battery.They do allow for power in very remote applications and are great for campers and areas were power is not always available. They are much "greener" then portable generators.a solar panel is a thing that you can put on top of a house or a lamp post that collects sunlight and charges up a battery which can power tvs, friges, freezers and moreSolar panels are a batch of multiple silicon material put together in order to store photons and covert them into photovoltaic cells.
How much electricity do solar panels produce?
A single photovoltaic cell typically develops a small voltage ... like 1/2 volt ... in full sunlight, and delivers between 1 milliampere and 2 amperes of short-circuit current depending on its area. For more voltage, several cells are connected in series. For more current, several cells are connected in parallel. The solar array that powers the International Space Station is capable of 140 kilowatts.
Does the area of a solar cell effect the voltage output?
It does :)
What is a RAPS solar panel?
Remote Area Power Supply.
What is the percent area cleaned by the wiper if the 180 degree rotational wiper diameter D is equal to the length of the solar panel D equals 156Cm and Breath of solar panel equals 78Cm?
Area covered by the wiper is that of a semi-circle with diameter D, or the length of the solar panel - 156 cm.So the area = (1/2)*(PI/4)*(D2) = (1/2)*(PI/4)*(156cm2) = 9556.72 cm2Now find the area of the solar panel: area = length*width = 156 cm * 78 cm = 12,168 cm2Now % area cleaned will be the area of the wiper / area of the panel:9556.72 cm2 / 12168 cm2 * 100% = 78.5%
Why is it important that the surface of the solar panel has a large area?
so it can get more sun
Does the area of a solar cell affect how much electricity it produces?
Yes
How much you can save with solar panel systems?
Savings from solar systems depend on the total area where the solar panels are installed. You can use solar savings calculator available at solarbuddy dot com to know how much you can save on electricity bill by installing solar panel systems on your home roof top.
What is the voltage in your area?
the energy in the area is called ME-Kos.
How does the output voltage of a solar cell depend on thearea of the solar cell exposed to the light?
because the out put voltage of a solar cell is directly proportional to the area of the solar cell exposed to sun light. Testing your solar cell with the application of shading will cause a loss of power and lower voltage and current at the peak power point, However, if you are measuring open circuit voltage only, and this is only one cell, not a collection of solar cells making up one solar panel, the open circuit voltage will stay almost the same until full shade is applied. I would need more information on the solar cells such as are there many in one panel that you are testing or just one solar cell. Is it an array you are testing or just one panel? I will assume it is one panel since you said "solar cells". This means the first statement I made holds in that the open circuit voltage will change very little with the application of shade. A better test is to measure the short circuit current flow. Short the output leads together and measure the maximum current yo can get in full sun light. Now apply your shading and continue measuring the current. Make up a table Shade---------------------Current Measured 0%--------------------------2 amps 10%------------------------1.8 amps . . . 80%-----------------------0.4 amps Now repeat the measurements only this time open circuit the solar cells, no load of any kind, just the voltmeter. Shade-----------------------Volts 0%---------------------------35 volts 10%-------------------------35 volts 50%------------------ To complete the testing use a variable resistor and a watt meter. Make a table recording the the shading and maximum power you could develop and the voltage across the resistor. For instance, in full sun light, adjust the resistance until you get the peak or maximum power reading on your watt meter.
How many solar panel for 4kW home?
The answer can be varies depending on climate area, fluctuation of demand and the mode of solar panel connection.For a general calculation with a stand alone solar panel on a moderate climate.AssumeThe 4 kW imply average 4 kW on 24 hr basisSolar Cell efficiency = 10%Solar irradiation = 6 hr/day at 1000 W/m2Safety factor = 50% for panel deterioration + Fluctuation of demand1) Calculate energy demand = 4 kW x 24 hr = 96 kWh2) Calculate solar cell energy generation, 1 m2 of panel could harvest energy = 1 kW/m2 irradiation x 10%/100 solar eff x 6 hr/day= 0.6 kWh/day.m23) Find the total area, Area = energy demand / energy per panel = 40 kWh/0.6 kWh/day.m2 = 66.7 m2 of solar panel4) Adjust design for safety factor 50% = 66.7 m2 x 1.5 = 100 m2 of solar panel
How many silicon solar cells of 2 sqcm area are to be connected in a solar panel to produce 20v?
silicon solar cells of 2 sqcm produces 0.5V and power of 0.7W. So to get 20Volts 40 solar cells are to be connected in sieries.
What two factors affect the amount of solar energy that an area receives?
Time of day & cloud cover.
Where can you install a solar panel in your home?
Solar panels come in many variations and it is best to seek out a reputatable company that installs them. You can have them installed in your roof as well as detached and placed on the roof or even in an area of your yeard.
