Solar Power. The energy of the future.

Solar is a great investment in your future

  • Clean power generated while the sun shines
  • Save money off your power bills
  • Add value to your home
  • Be kind to the environment

We can help you choose the system that is right for you based on your power needs, your roof size, orientation and other factors about your home (such as potential shading).

Residential solar systems are called a variety of things including on-grid, grid-connected and  grid-tie. These all relate to a system where a home will already be connected to the mains supplied power. (If you are off-grid, please see our section on Stand Alone Power). The addition of solar will either reduce the amount that needs to be pulled from the grid, or in the case of a larger system, actually export power back to the grid as well. 

Residential systems are (generally) not a power storage system. They don’t use batteries. They use power when it is produced, and they pull any extra power needed from the grid.  This all happens without any effort or attention from you.

Depending on where you are located and when you connect – you may be on a gross feed in tariff or a net feed tariff for the power you are producing. 

The basic function of a solar system and its components is to create energy from sunlight. Panels convert the energy in light to DC current which then runs to an inverter which convert to AC power at 240v. This power is then either used in your house or exported to the grid.  Depending on a few factors such as your metering system and if you are on a gross or net tariff, you will then either reduce your import of power from the grid (thereby saving money) or exporting power to the grid (thereby making money, which is deducted from your power bill). 

You may be able to get some information on your power production from your power bill. Or, you may be able to get power production information from your inverter. There are various ways to access this information from your inverter. It is displayed in real-time during the day and for some inverters it is stored and can be accessed by a computer (some with wireless technology, others with cables.) Some inverters record all data so you can access it later.

If you are in doubt, please contact LJW Solar and we can explain if this data can be accessed for your system.

We also offer a complete monitoring system which we wire up and connect to your internet connection, and  allows you to see data on your system performance as well as data on your household consumption.

Because there have been several changes in the last few years with solar power, we recommend you contact us for a clear explanation about what solar power will do for you. This varies from state to state.

Currently, with the upfront assistance and the net feed in tariff offered in NSW, a correctly sized solar power system will pay for itself in about 6-7 years, and continue to offer an amount of clean, free power for decades to come.  It really is a great investment.

A system will last you for a long time.  For example:

  • The panels will last from 30 to 40 years. There is a written output warranty for 25 years.
  • The framing system will last 30 years or more. It has a warranty for 10 years.
  • The inverter is designed to last for 15 or more years, and has a warranty for 10 years.

Because LJW Solar has been installing solar systems since 1982, we are one of the few companies in Australia who can actually talk about the life of the system with the voice of experience. We have systems which have outlived their warranty periods and are still going strong.
