FAQ

Most frequent questions and answers
  • solar photovoltaic (PV) panels are made up of many layers of semi-conducting materials, (ours are made of silicon)
  • the panels absorb the suns rays and create a flow of electricity
  • the electricity is then passed through an inverter, this changes the direct current (DC) to alternating current (AC)
  • this electricity can then be used to power your household appliances, charge your battery, or be exported to the grid
  • Solar panels require daylight to work, not direct sunlight. This means even during cloudy days, your panels will still work.
  • It depends how much of your roof is shaded. Panels are installed in “strings” – they are all connected to each other. If there is shading, it can affect the perfomance of the other panels, not just the one that is shaded. If there is shading, we can install the panels in areas that aren’t shaded and install microinverters – these are individual inverters on each panel, connecting to a central unit.
