Why Do Most Solar Panels Have 36 Solar Cells?

Most solar panels that provide energy to a 12 volt solar system have 36 cells for a easy cause.

Solar cells are available a wide range of sizes. Some are 3 inches by 3 inches. Different sizes are 3 by 5, 4 by 4, and 6 by 6. There are another odd sizes, too, however these are the standard sizes used for producing electrical energy in properties and cabins.

Solar cells produce DC (direct present) electrical energy when uncovered to daylight. How this occurs is mentioned in one other article referred to as,”How within the World Can a Little Solar Cell Make Electrical energy”. For this dialogue, it is sufficient to know that every cell on this dimension vary produces about .55 volts. That’s, slightly greater than half a volt ติดตั้งโซล่าเซลล์ พร้อมอุปกรณ์.

In off-the-grid solar setups, electrical energy produced by the cells in a solar panel is saved in batteries. With out this, there can be no electrical energy for the house or cabin after darkish. Nonetheless, batteries have their limits and could be broken if over-charged. Due to this fact, it is vital that your solar panels are producing the quantity of electrical energy the batteries can deal with.

In a 12-volt system, for instance, the batteries can obtain as much as 17 volts or so on a continuing foundation with out inflicting them harm, as long as the electrical energy in them is getting used every day. Some voltage is misplaced because it travels down the wire to the battery so producing about 19 volts is right.

Here is the maths… If every cell contained in the panel produces.55 volts and we would like the panel to provide about 19 volts, we will divide 19 volts by the quantity of volts produced by every particular person solar cell, .55 volts, and we get 35.5. Which means if we’ve 35.5 solar cells — rounding as much as 36 cells — every producing slightly greater than half a volt, and we string them collectively correctly, we’ll get 19.8 volts popping out of our solar panel.

36 solar cells x.55 volts = 19.8 volts.

As I mentioned earlier than, slightly little bit of that voltage can be misplaced because it travels down the wire to the batteries. The voltage can be lowered to about 16 volts by the point it will get there. That is nonetheless sufficient to push the electrical energy into the battery to be used now or later.

And THAT’S why most solar panels have 36 solar cells.
