How Is Solar Panel Efficiency Measured?
A PV cell, commonly called a solar cell, is an electronic device designed to harness the energy from photons of light and convert it into electrical energy. This conversion process is achieved through the photovoltaic effect, whereby the solar cell generates an electric current when exposed to light.
Anti-Reflection Coatings
Anti-reflection coatings on solar cells are similar to those used on other optical equipment such as camera lenses. They consist of a thin layer of dielectric material, with a specially chosen thickness so that interference effects in the coating cause the wave reflected from the anti-reflection coating top surface to be out of phase with the ...

Solar Calculations Math Tutorial for Solar Energy Power Systems
If the total battery capacity is 1800Wh (Watt-hours), then, in theory, you can use an 1800W (~2.5hp) motor for 1 hour before the battery is drained. By the same token, you could use a smaller 100W motor for 18 hours. They both will use the same amount of energy, i.e. 1800 x 1 = 100 x 18, but will use it at different rates (power).
