How big would a solar power cell need to be...to power a 0.5 A load (240v)? How about 1 A?2? 10? 50?
Just curious.
Just curious.
So you say that a 1.68 m2 pv solar cell area can produce 240 watts, or 143 watts per m2. The available insolation at high noon at sea level is about 1000 watts per m2, so this implies about 14.3% efficiency. Here is a triple-junction solar pv cell that Emcore claims has 27.5% efficiency:DaleSwanson said:That's about 1.68 m2 per 1 amp at 240 volts. To get the other sizes just multiply.
The size of a solar power cell can vary depending on the amount of energy it needs to produce and the efficiency of the cell. Generally, a solar power cell needs to be large enough to capture a significant amount of sunlight and convert it into usable energy.
The size of a solar power cell is primarily determined by the amount of energy it needs to produce, the efficiency of the cell, and the type of solar technology used. Other factors such as space availability and cost may also influence the size of a solar power cell.
Yes, there are different sizes of solar power cells available. The size of a solar power cell can range from small portable panels to large panels used in commercial and industrial settings. The size of the solar power cell needed will depend on the specific energy needs and available space.
To determine the appropriate size of a solar power cell, you will need to calculate your energy needs and consider the efficiency of the cell. You can also consult a solar energy professional who can help you determine the most suitable size for your specific needs.
The size of a solar power cell does not necessarily determine its performance. A larger solar power cell may have the potential to produce more energy, but it also depends on its efficiency. A smaller, more efficient solar power cell can also produce a significant amount of energy. Ultimately, the size of the solar power cell should be tailored to your specific energy needs and available space.
