Delta Electrics were appointed at the solar agents for BP Solar in the Northern Territory in 1988. BP Solar are world leaders in solar power (Photo Voltaic) technology. Some of the largest solar PV electricity systems in Australia have been delivered by BP Solar, such as 100kW on a Cadbury Schweppes facility in Sydney and 200kW on the Queen Victoria Markets in Melbourne. BP Solar is also a key participant in the Australian Government Solar Cities program which aims to test marketing strategies and tariff structures to support the uptake of energy efficiency and solar technology across Australia.
Commercial-scale grid connect or remote power
Delta Electrics specialises in the design, supply and installation of medium to large scale solar power systems for schools, businesses, remote properties and Aboriginal communities. This includes systems that can be connected to the main power supply (grid-connect) or for remote locations that do not have a connection to the main power grid (Remote Area Power Systems or RAPS). We also specialise in the design and installation of hybrid solar power systems that can harness solar power during the day and back it up with efficient Diesel power generation at night or during extended periods of cloudy/rainy weather.
Solar power equipment for households (domestic grid-connect)
We work closely with local Darwin-based solar power installation companies to supply solar power
systems for people interested in installing solar power on their homes.
Government rebates and financial assistance
Financial assistance is available to households and businesses to help reduce the cost of installing solar power in the form of Small-scale Technology Certificates (STCs). STCs (formerly know as Renewable Energy Certificates or RECs) can be generated when you install a grid-connected solar power system and reflect the reduction in greenhouse emissions your system will create (the bigger the system, the more STCs you can create). STCs are traded much like shares on the stock market and can be worth up to $40 each. An average sized system (1.5kW) installed in the NT creates 34 STCs.
Households and businesses not connected to the main power grid can also generate STCs when they install a remote solar power system that is not connected to the grid provided that you are:
- More than 1km from the mains grid AND
- It would cost at least $30,000 to get connected to the grid.
Remote Solar Power systems of up to 20kW are eligible for these STCs.
Solar Credits Multiplier
Households and businesses that install a grid-connected solar power system can get an additional benefit under the Federal Government Solar Credits scheme whereby they can get a multiple number of STCs for systems up to 1.5kW. For example, a house in Darwin that installed a 1.5kW grid connected system could generate 172 STCs if the system was installed before 30 June 2011 or 102 STCs after 30 June 2011.
Remote power systems
Households and businesses not connected to the mains power grid that install a remote solar power system can get an additional benefit under the Federal Government Solar Credits scheme whereby they can get a multiple number of STCs for systems up to 20kW. For example, a remote property in the NT that installed a 20kW off-grid solar power system could generate up to 2,300 STCs if the system was installed before 30 June 2011 or 1,380 STCs after 30 June 2011.
The value of STCs varies and can be sold via an authorised STC trader or via the Federal Government Clearing House.
This multiplier will be reduced over the coming years as follows:
- From 5 to 3 on 1 July 2011
- From 3 to 2 on 1 July 2012
- From 2 to 1 from 1 July 2013
As you can see from the information above, if you are considering installing a solar power system on your home or business you should act sooner rather than later in order to maximise the financial benefit of your STCs.
Another financial benefit of installing a solar power system on your home or business is the potential to sell your solar energy to your energy provider. In the NT, we have a gross feed-in tariff scheme which means that you can get paid for ALL the solar power produced from your system. The NT utility authority, Power and Water Corporation, will pay households and businesses the following for the solar power they produce:
- Households – 19.23 cents per kWh
- Commercial customers – 22.37 cents per kWh
