Solar Power FAQ’s
Solar Power FAQs
What is solar technology?
Photovoltaics (PV) is the name for the technology – more commonly referred to as “solar power”, “solar energy” or “solar panels”.
How does solar power work?
PV panels convert sunlight into electricity when sunlight passes through panels of glass onto a semiconductor material, usually silicon wafers. When sunlight hits the semiconductor it causes electrons to be released. The free electrons create an electrical current that generates electricity.
Do solar panels work?
PV is only truly effective where it has enough sunlight of sufficient intensity to work. PV is not right for every house, because the orientation of the home will also affect its ability to collect sunrays.
What are key solar energy facts I should know?
Over the past few years PV panels have reduced in price while increasing in performance, making them an attractive option for homeowners seeking a renewable energy source.
You can also effectively sell your surplus energy backto the grid when using an import/export meter!
Why solar panels for electricity?
PV panels can be used to generate part of a household’s electricity needs: either directly, by connecting to the house; or indirectly, by charging a battery bank. PV produces no noise or emissions, and can be mounted on a building or a separate frame. This makes them ideal for using in an urban environment.
What are the advantages of solar power?
- Some key advantages of solar power are:
- Clean, free source of renewable energy
- Reliable and requires little maintenance
- Quiet and can be installed in urban areas
- You can ‘sell’ your surplus energy back to the grid
How much energy does solar generate?
A PV array of between 8 m2 and 10 m2 can produce about 1 kW of power when operating effectively. Our 3.2kW system can generate up to 5,000kWh of energy.
Is it safe?
As with any technology involving electrical current, care should be taken when installing or inspecting PV panels. However, correct day-to-day use is perfectly safe. Some power companies may require you to post signage that alerts tradesmen to the presence of solar panels, so that they know to disconnect the system before performing maintenance work.
How much will it cost?
The cost of a Solar energy system is affected by the number or size of the array (number of panels) required. We are happy to visit you to provide you with an assessment.
