The science behind Solar Power
Australia is one of the sunniest countries on earth, and that makes renewable solar energy a very wise investment. Solar Power can be used in a variety of ways – to supplement your everyday living, for solar hot water heating, swimming pool heating or for solar air conditioning.
Today’s solar technology is more efficient than ever before. The solar panels we are all familiar with utilise solar PV cells (or solar photovoltaics) to effectively convert sunlight into renewable energy.
Sunlight consists of particles of solar energy called photons. As a PV cell is exposed to sunlight, some of the photons are absorbed by the PV cell. The process frees electrons which in turn creates a voltage differential between positive and negative layers of the semiconductor material, similar to a battery.
Solar PV cells burn no fuel and have no moving parts which makes them virtually maintenance free, environmentally friendly, safe and silent.
By installing a Leda Solar Power System you can produce all the electricity you need to run your home without any greenhouse gases being released into the atmosphere.
If you are interested in solar panels, you need to engage a trusted solar panel installer, like Leda, to provide the solar system most appropriate to your needs.
How Solar PV works
- Sunlight strikes the Solar PV panel creating an electrical field that generates DC (direct current) electricity
- The inverter converts the DC power generated by the solar panel into the electricity used in your home (AC 240 volt electricity)
- The generated electricity can then be used safely in appliances around the home
- Any extra electricity generated can be sold back to receive Feed-in Tariffs that will help lower electricity bills even more (regulations vary by state)
- The bi-directional meter measures the amount of electricity that is imported and exported into the grid
The Government provides financial incentives through the Small-Scale Renewable Energy Scheme that help reduce the cost of energy efficient products such as Solar PV and Solar Hot Water. It does this by assessing energy efficient installations according to the amount of electricity they produce or displace. Each installation is allocated a specified number of STCs (Small-scale Technology Certificates).
The number of STCs varies with the location, that is, where you live. Australian postcodes have been classified in Zones that affect STCs and pricing of PV installations.
