In this experiment, we are going to use a 100 W desk lamp to simulate the solar radiation. In an ideal case the irradiance of a 100 W light bulb at a distance of 0.15 m is around E= 350 W/m2. We are going to use this value in our solar cell efficiency calculations.
A PV array can be composed of as few as two PV panels to hundreds of PV panels. The number of PV panels connected in a PV array determines the amount of electricity the array can generate. PV cells generate direct current (DC) electricity. DC electricity can be used to charge batteries that power devices that use DC electricity.
The power of a solar cell is the product of the voltage across the solar cell times the current through the solar cell. Here’s how to calculate the power the solar cell delivers to the motor: The maximum theoretical power from our solar cell, P max , is the product of the V oc and I sc .
This experiment measures the current as the distance between the solar cell and the lamp changes. The power generated by the solar cell is calculated and the change in power

6 FAQs about [How much v does the solar power of a desk lamp generate]
How do you measure a solar cell with a desk lamp?
Measure the length and width of the solar cell with a vernier caliper and find its surface area. Record the results in Table 1. Place the desk lamp on top of the solar panel. Measure the distance from solar cell to the desk lamp with a ruler. Adjust the distance to 0.15 m, and turn on the desk lamp.
How do you use a solar cell on a desk lamp?
Place the solar cell on the table directly under the desk lamp and switch on the desk lamp. Connect the solar cell with the electric motor and a DMM to measure current. Record the solar cell current and observe the turn speed of the propeller of the electric motor.
How efficient is a solar PV system?
Experimental PV cells and PV cells for niche markets, such as space satellites, have achieved nearly 50% efficiency. When the sun is shining, PV systems can generate electricity to directly power devices such as water pumps or supply electric power grids.
How do you install a solar module on a desk lamp?
Place the desk lamp as CLOSE AS YOU CAN to the PV cell. Measure the distance between the bulb surface and the PV Module. You need to add 3.7 cm to your measured distance to have the actual distance between the filament inside the bulb and the solar cell surface located underneath the module’s protective cover.
Can a solar panel be used with a desk lamp?
Solar panels can be used with desk lamps that can accommodate higher wattage incandescent bulbs. Higher wattage bulbs will allow the solar panel to produce more power, and they will also get hotter with higher wattages. However, many desk lamps warn against using bulbs more powerful than 60 W or 75 W equivalent bulbs. Some work lights, however, may take 100 W or even 150 W bulbs.
How many watts can a PV cell produce?
However, one PV cell can only produce 1 or 2 Watts, which is only enough electricity for small uses, such as powering calculators or wristwatches. PV cells are electrically connected in a packaged, weather-tight PV panel (sometimes called a module). PV panels vary in size and in the amount of electricity they can produce.
