What size system will I need to run my home?

That entirely depends on your energy usage and your geographical location. A 1.5 kW system is currently the “entry point” for grid connect.It will cover between 16 and 25% of the energy consumption of a medium household. A 4-5 kW system will cover 100% of the energy consumption of a medium energy use household. Learn more about solar power system sizing.

Any size grid connect solar power system will reduce your yearly power consumption and your power bill. Naturally, the bigger the system, the bigger the benefit.

To make the most of solar power, the key is to implement simple energy efficiency strategies. It is easy to conserve energy by using appropriate lighting and efficient appliances. Running high power appliances such as electric bar heaters, electric hot water systems and air conditioners etc. is really not economical.

Instead of considering a very large solar system; you can also invest in energy efficient heaters, solar hot water and design features such as strategically placed vents or insulation to avoid heat entering the house in the first place. In summary – all your energy can be supplied by solar power and your budget and daily energy usage will determine the size of your solar power system.

How long will my grid connect solar power system last?

The life of Solar modules that have been tested in the field showing small reductions in power output after 20 years, mostly because the glass surface becomes a bit dull and reflects more light. All our solar panels carry an output warranty of 25 years. There are solar panels delivering power in Australia today that were installed more that 30 years ago. The electronic components such as inverters, being the most sensitive, will last 10 -15 years.

Should I choose monocrystalline, thin film or polycrystalline solar panels?

Between monocrystalline and polycrystalline there isn’t a lot of difference except that a polycrystalline panel is slightly larger than the equivalent wattage in monocrystalline. Thin film panels are larger again and the extra space can take up valuable rooftop real estate in terms of adding extra panels at a later date. There are other issues to consider with thin film panels, explained in further detail here.

What can affect the costs of installing a grid connect system?

A base installation rate includes the grid connect system being installed on a pitched metal roof facing north with appropriate surface area available.

Additional costs will be incurred for a flat or tiled roof; any equipment upgrades and extended warranties.
