Solar panels
Photovoltaics (PV) is the name for the technology more commonly known as solar panels. 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.
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 emmissions, and can be mounted on a building or a separate frame. This makes them ideal for using in an urban environment.
How it works
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.
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 sun rays. The best way to know is to talk to a Right House expert consultant.
Why it's good
- Clean, free source of renewable energy
- Reliable and requires little maintenance
- The panels in the systems Right House recommends come with 40 year guarantees
- Quiet and can be installed in urban areas
How much does it generate?
A PV array of between 8m2 and 10m2 can produce about 1kW of power when operating effectively. This is a typical domestic size and will generate between 10 and 20% of an average homes electricity requirements.
Is it safe?
As with any technology involving electrical current, care should be taken when installing or inspecting PV panels. However the day-to-day use presents no immediate dangers.
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?
Basic PV systems begin at $10,000 - $12,000 (1kW system). The cost is affected by the number or size of the array (number of panels) installed.
