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

How can a fresnel lens enhance the efficiency of a solar panel?
A Fresnel lens can enhance the efficiency of a solar panel by concentrating sunlight onto a smaller area, increasing the amount of light that reaches the solar cells. This helps to generate more electricity from the same amount of sunlight, improving the overall performance of the solar panel.
Why is the pipe inside the box of a solar panel made as long as possible?
The longer pipe inside a solar panel box helps increase the surface area exposed to sunlight, allowing for more effective heat absorption. This helps the solar panel to heat up the water or fluid passing through it more efficiently, thus improving the overall performance of the solar panel system.
Does the output voltage of a solar cell depend upon the area of its surface exposed to the light?
Yes, the output voltage of a solar cell is influenced by the surface area exposed to light. A larger surface area typically results in more incoming photons, which can generate a higher voltage. This is why solar panels are designed with multiple cells to optimize energy production.
What factors affect the resistance and voltage?
Factors that affect resistance include material type, length, cross-sectional area, and temperature. Factors that affect voltage include the number of cells in a circuit, the presence of a power source, and the type of material conducting the current.
How much power can I get out of a solar panel that is 1 square meter in size?
On average, a solar panel with an area of 1 square meter can generate around 150-200 watts of power under optimal conditions. However, the actual power output can vary depending on factors such as sunlight intensity, angle of sunlight, shading, and efficiency of the solar panel.
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

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.
Does the area of a solar cell affect how much electricity it produces?
Yes
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 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.
