The electricity generated can be used in your home or sent back to the grid, depending on your energy needs.
Solar panels are highly dependent on sunlight and work best on south-facing roofs with a slope between 15 and 40 degrees, as this maximizes their exposure to sunlight throughout the day.
To estimate the energy production and cost of a solar panel system, you can use tools like PVWatts.
Now, let’s take a closer look at the process of converting sunlight into electricity:
- Photovoltaic cells absorb sunlight: Solar panels are composed of photovoltaic cells, which are made of materials like silicon that can absorb photons from sunlight.
- Conversion of photons into an electric current: When sunlight strikes the photovoltaic cells, the energy from the photons knocks electrons loose from their atoms, generating a flow of electrons or an electric current.
- Direct current (DC) to alternating current (AC) conversion: The inverter is responsible for converting the DC electricity generated by the solar panels into AC electricity, which is the type of electricity used in most households. This allows you to use the electricity in your home or send it back to the grid.
So, by harnessing the power of the sun, solar panels enable the generation of clean and renewable energy that can power your home!
