FAQ’s

How does the Solar PV System Work? 

Solar power is a clean, green, renewable energy source that you can generate from your own home. Simply install a solar power system on your roof and begin creating your own electricity while the sun shines.

 

When the sun light falls onto the solar panels on your roof, they produce Direct Current (DC) electricity. This DC electricity is transmitted from the solar panels (modules) to an inverter which converts the DC electricity to Alternating Current (AC). The AC electricity is then transmitted to your home’s distribution system to supply electric power as required throughout the daylight hours.
During non-sun light hours, utility power provides the electricity you need.

Why Go Solar? 

Installing a Solar PV system has many advantages:

 

  • Helps to offset rising energy costs.
  • Possibility to become energy neutral and never pay an electricity bill again.
  • Reduces your carbon footprint and helps to save the environment.
  • No fuel is required.
  • No emissions.
  • Generates no waste.
  • Reduces dependence on coal and oil – conserving fossil fuels.
  • Requires low maintenance.
  • Saves carbon emissions -- solar power alone can reduce approximately 8.5 tons of CO2 per household per year which equates to taking 3 cars off the road.

What is a Kilowatt-hour?

It is a measure of energy where 1 unit or 1 Kilowatt-hour is equal to 1000 watts.

 

What size systems are available?

Solar systems are measured in Kilowatts (kW). A Kilowatt is a measure of electric power. 1kW is equally to 1000 watts. There are wide range of sizes and options available at SDS. Please check our products page on this website.

What warranty is provided with the installation?

 The warranty depends on the panel and inverter brand that you choose and install – It can vary from 5 years to 10 years. The warranty is given by the respective manufacturers. SDS will assist in handling all warranty claims. All our panels carry a 10-year product warranty from the manufacturer. There is also a 25-year manufacturer performance warranty on the solar panels.

How long does a system take to install?

A 1.5KW system should take around 3 to 4 hours to install. Bigger systems will take longer according to their size.

Can I upgrade once I have installed a system?

This depends on the capacity of your existing inverter and availability of roof space. If you had installed a larger capacity inverter initially, yes there is a possibility to add more panels. If you want to increase the overall capacity (more kW), it is more than likely that you need to upgrade your inverter and add more panels. Our Sales team will assist you in more detail.

How much roof space is required and which way do the panels face?

A 1.5kW system requires around 12m2 of roof space. It is preferable to have this on a north-facing roof.

What if I have a flat roof?

No problem. Roof mounting systems (Tilt kits) designed to overcome this issue and can be installed to angle your solar panels at an adequately slanted position.

What is feeding power back into the grid?

The power that your solar system produces is first used to meet your own requirements in the house. Any excess power generated that is not used inside the house will flow back into the electricity grid. The export/import meter installed by your electricity retailer will record the units exported by you into the grid. Please refer to their website to check on the current tariffs paid by them for the power fed into the grid (feed-in-tariff).

What is a feed in tariff?

For a customer a feed in tariff is referring to a credit amount your electricity provider supplies you with for the electricity your system provides to the grid

What size system do I need to cover my electricity bill?

A SDS sales consultant will be the person to explain this question in detail. He will do a cost benefit analysis to help you choose the right system that takes care of your electricity bill and at the same time be mindful of your budget constraints if any for making the upfront investment on the system.

What do I need to tell my electricity provider once I have a system installed?

You will need to contact your electricity provider and inform them that you wish to connect your solar system to the feed-in grid. This requires a new import-export meter to be installed by them.

What happens when there’s no sunlight?

Solar PV systems only produce electricity when they are exposed to sunlight, they do not produce electricity at night.

Will my solar panels be covered by my home insurance?

This depends on your insurance company. Please contact your insurance provider and inform them that you wish to include your system in your Home and Contents policy.

What happens in a black-out?

 Quite simply your system will automatically shut down if mains power is lost, and will start up automatically when power is restored. This is a safety regulation.

What is an inverter?

An inverter is a crucial part of your solar system. It converts the output of the solar panels, that is DC (Direct Current) power, into AC (Alternating Current) power. This is what your house and the grid are designed for.

How much will this cost me?

This depends on the size and the brand that you choose install. The Federal Government’s Solar Credits scheme reduces the cost to the customer considerably. Our prices quoted to you are after these rebates from the Govt.

Have the solar panels and inverters been tested and approved for quality to Australian standards?

Our panels are tested to meet the standard IEC61215 and IEC61730 and the inverter complies with standard AS/NZ4777. Please refer to the approved panels and inverters list released by Clean Energy Council.

Will the electrician installing the product be qualified?

 Yes, our installers are licensed electricians and are accredited in Design and Installation of Photovoltaic systems by the Clean Energy Council.

Are solar systems as effective in winter?

Solar Photovoltaic systems rely on sunlight and not heat. However, due to reduced daylight hours during winter the output will be reduced in comparison to summer.
