The first solar cells were invented in 1954 and only captured 6% of the sun’s energy in direct sunlight. Today, we’ve raised that rate to just under 20%. There are many variables when it comes to solar panel output. The quality of the sunlight you receive, tilt angle, and cleanliness of your panel will have a direct effect on the energy production. However, let’s say your panel was just cleaned and is in direct sunlight. With a 60-cell solar panel, it would generate about 20 watts of power.
The power of one solar panel is usually enough to power a small appliance or a handful of light bulbs. That number might seem like a small amount of electricity, but this is why we install whole solar arrays with multiple panels on your property. Also, in many cases, solar energy systems are intended to reduce electricity bills, not fully replace the power grid.
