Solar FAQs
Solar energy is generated by converting the energy from the sun into electricity. This is done using solar panels, which are made up of photovoltaic cells that convert sunlight into direct current (DC) electricity. This DC electricity is then sent to an inverter, which converts it into alternating current (AC) electricity that can be used in your home or business.
Solar PV panels use semiconductor technology to convert the sun’s rays into usable electricity. The panels are arranged in a series and connected in parallel to maximise power generation. Solar energy is produced when photons (particles of light) hit the solar cell.
Batteries are used to store excess electricity produced by the solar panels, and to supply power when the sun is not shining. The battery will store electricity during daylight hours and then deliver it through the inverter at night or on cloudy days.
The cost of installing solar panels can vary depending on a number of factors, such as the size of the system, the type of panels used, and the location of the installation. On average, the cost of installing a solar panel system can range from €9,000 to €12,000 for a typical residential installation.
The amount of electricity that a solar panel system can generate depends on a number of factors, including the size of the system, the location of the installation, and the amount of sunlight the area receives. On average, a typical solar panel system can generate between 1,500 and 2,000 kilowatt-hours (kWh) of electricity per year.
Technically, if batteries are utilised, yes. But practically, it is advised to utilise solar in addition to grid power if it is accessible. Solar photovoltaic systems can be linked with your current power sources (such as grid electricity, an inverter, a diesel generator, etc.) such that solar power is always given the top priority to be used first. However, it is rather typical to have Solar systems that are battery-backed if you are using Solar PV for nighttime usage or in a remote location.
