Your solar questions
What is solar technology and how does it work?
Photovoltaics (PV) is the name for the technology – more commonly referred to as “solar power” or “solar panels”.
Solar 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, directly or indirectly, it causes electrons to be released. The free electrons create an electrical current that generates electricity.
Do solar panels work?
Solar 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.
Why solar panels for electricity?
Solar PV panels can be used to generate all or part of a household’s electricity needs, either: directly, by connecting to the house; or indirectly, by charging a battery bank. Solar 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.
Is solar energy economically viable?
Over the past few years solar PV panels and other solar technologies 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 back to the grid when using an import/export meter!
To maximise the economic advantages of solar energy, we recommend a self-use hybrid solar PV system, which uses smart inverter technology and battery storage. This enables you to consume up to 80% of energy generated.
What are the advantages of solar power?
Some key advantages of solar power are:
- It’s a clean, free source of renewable energy.
- It’s reliable and requires little maintenance.
- Our solar panels can last 30 years or more.
- It’s 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 8M2 and 10M2 can produce about 1 kW of power when operating effectively. Our 3.2kW system can generate up to 4,500kWh 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. All work should be carried out by a qualified electrician trained in carrying out solar installations, as this is classified as high-risk electrical 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, as well as the type of system chosen (eg, grid-tied vs hybrid). See more information on pricing here. We are happy to provide you with a free assessment and quote. Please contact us.
