- Higher energy usage in the morning - east facing panels
- Higher energy in the afternoon - west facing panels
- Sunlight Absorption: When sunlight hits a solar panel, it contains energy in the form of photons. The efficiency of a solar panel is directly related to its ability to absorb these photons.
- Photon-to-Electron Conversion: Solar panels are made up of semiconductor materials (usually silicon) that contain many tiny cells. When photons from the sunlight strike these cells, they can dislodge electrons from their atoms, creating an electric current.
- Losses: Not all the energy from the absorbed photons gets converted into electricity. Some energy is lost due to various factors, including:
- Reflection: Some photons bounce off the panel's surface and are not absorbed.
- Thermal Losses: Solar panels can heat up in sunlight, and this heat energy is typically lost.
- Resistance: Electrical resistance within the panel's materials can cause some energy loss.
- Electrical Output: The electricity generated by the solar panel is collected and sent to an inverter, which converts it from direct current (DC) to alternating current (AC) for use in your home or to feed into the grid.
If you have a property that has potential shading issues such as trees, etc, an optimised system may be more beneficial to you. An optimised system also offers exceptional consumption monitoring down to the panel level to the point where if there is an issue with a panel, it alerts the installer.
A standard string system reduces its output if a panel is shaded and has no output if there is a fault in the circuit. The reason for this is that string system panels are wired in a series while in an optimised system, the DC optimisers are wired in a series and the panels are wired in parallel to them. This allows the circuit to bypass a faulty panel because there is another path.
