There are three main types of free energy generated by solar. In order to calculate the free energy you need to know:
Solar panel’s energy generated (energy in milliwatts, or mWh)
Time that the solar panels are on
The solar panel’s efficiency (energy in watts per square metre)
Let us take a look at each of them.
Solar panel’s energy generated (energy in milliwatts, or mWh)
Solar energy is produced as a result of the movement of heat and light over the solar panel’s surface. When a solar panel is on, a certain percentage of energy is used by an optical sensor which converts visible light into infrared light. This infrared heat is collected by a sensor, which converts that infrared heat into heat and motion. An optical sensor, also called a photovoltaic cell, is the component which converts the light collected by an optics system with a photovoltaic (PV) cell into electricity.
Free energy generated within the solar panel
The conversion of radiation collected by the solar panel into thermal energy is called the free energy. This energy is used by the photovoltaic cells. One of the main advantages of PV is its low cost. This is because the cells can cover large areas. Also its efficiency can be much higher than that of an aluminum frame panel (see solar panels: efficiency ).
Solar panel’s time on
Solar panels are put on for a specific moment in time, usually within one hour, but can be off for different periods. However PV panels provide a significant energy back-up until batteries or other sources are in place. This includes using the energy stored in the batteries.
Solar panel’s efficiency
Solar panels are not energy efficient devices, but they are not inherently useless. In order to get the same energy output at a given time you need to convert some of the energy produced by the solar panel into something else, and that means efficiency has increased with the number of cells in the PV panel, with each larger PV cell having a larger area to convert the solar energy to heat and motion.
Solar panel’s efficiency is calculated using the following equation:
E efficiency = V รท C 2
V is the area of the solar panel, C is the amount of daylight in the area, and 2 is a constant factor. Since there is no change in the amount of sunlight (or the amount of darkness) over time, this constant factor is
