What products do you use?

Our preference is to install:

The inverter is the heart of the solar power system and is critical to the performance of the system. To compromise on the quality of the inverter compromises the performance of the system, and at worst renders it useless. We only choose products that are well proven in terms of performance, reliability and warranty. The suppliers we choose must have an Australian office and a competent warranty handling process.

Where do you service?

Electrical Sensations services all areas of Toowoomba and the greater Darling Downs region including Westbrook, Cambooya, Pittsworth, Highfields, Crows Nest,  Oakey and Withcott.

We can also travel to Warwick, Roma, Ipswich, Chinchilla and the Surat Basin for larger jobs.

How long have you been around?

Leanne and Nigel have been electrical contractors since 2004 and installing solar since 2008.

Do you do off-grid solar systems?

Yes! Nigel is qualified to install both on and off-grid solar systems (Lic no. A4911715).

Solar Systems

How much is the solar "rebate" (STC Financial Incentive)?
  • The Australian Government has a scheme in place to help reduce the cost of solar power systems. The financial incentive (or the ‘government rebate’ as it’s commonly called) is issued in the form of Small-scale Technology Certificates (STCs). Each STC has a monetary value from $0 – $40 – at the time of creating this blog, it’s around $35 per STC. The higher the STC price the more ‘rebate’ you get. Your solar system size, date of installation and postcode of the installation address will determine how many STCs you can get.
  •  Unfortunately, STCs isn’t a fixed amount – the price of STCs changes according to market conditions and demand. 
  • At the moment, the ‘rebate’ works out to be roughly around $440per kW installed. This means the total rebate you receive off the cost of a solar system is approximately
    • $2,150 – $2,250 for a 5 kW system
    • $2,800 – $2,900 for a 6.6 kW system
    • $4,350 – $4,500 for a 10 kW system etc

Why install a solar power system?
  • Save money on your electricity bill immediately. You will save from reduced energy consumption from the moment your solar system is turned on.
  • Help minimise the impact of planned future electricity price rises.  The price of electricity will rise. It is not a question of IF, but rather, WHEN and BY HOW MUCH?  A solar power system helps immune you from the inevitable price rises.
  • Increase the resale value and resale-ability of your home.
  • Reduce your carbon footprint and help make the world a greener place for our children and grandchildren.
What size system should I install?

The size of your solar PV system will depend on:

  • The physical unshaded area available for the installation of your panels
  • How much you are prepared to spend
  • What portion of your electrical consumption you wish to generate.

To work out what size solar PV system you require, you need to analyse your household’s daily electricity consumption. Your monthly or quarterly electricity bill measures your household’s electricity consumption in kilowatt-hours. Using your current average daily electricity consumption, as well as your expected FUTURE consumption, we size a system to suit you. Sizing a solar power system should not be a ‘one size fits all’ process. Our team of accredited solar designers can help work out what size system will suit you best.

Will solar panels stand up to hail?

The short answer is yes! Unless the hail is massive. Reputable solar panels are tested to take hailstones of around 20 mm. Anything bigger than that and you’re going to have much more damage than just your solar panels! We always advise customers to add their solar system onto their home and contents insurance just in case.

Can I add batteries to my pre-existing solar system?

Yes, you can!  There are a lot of factors to consider.  Firstly need to have enough panels to produce extra power to charge the batteries, or enough space on the roof to add additional panels.  You also need permission from Ergon/Energex and a suitable location for the batteries to be installed. There are ‘all-in-one’ solutions available, such as SonnenBatterie, Tesla PowerWall and Redback that have the battery as well as the battery inverter in one enclosure. There are a lot of details to get right when designing hybrid solar power systems. It isn’t as easy as grabbing any cheap batteries off eBay and hooking them up. If you are considering batteries, give us a call. We are more than happy to go through the options for batteries with you. 

If I install solar, will I still get an electricity bill?
There is no denying that getting solar can save you big bucks on your electricity bills, but will it completely wipe it out? 💰
The truth is probably not. While it’s possible, very few new customers completely eliminate their electricity bills anymore (unless they have batteries/off-grid). Here’s why:
  1. Solar only works when the sun is shining. All of the electricity you use at night, you have to buy from Ergon/Energex (unless you have batteries). 
  2. Over time, electricity prices have risen and the feed-in tariff has reduced. With the current Ergon feed-in tariffs, you pay around 3 times more for the power you buy from Ergon than what they pay you for any surplus that is sold back. 
  3. Ergon/Energex also charge a daily connection fee. 
Can I still put panels on if I don't have a north facing roof?

Absolutely! In fact, in some cases, east/west facing panels match the owner’s electricity usage better than a north-facing system. If you have the typical morning and afternoon spikes in usage, east/west systems can be preferable to a fully north-facing system.

How often should I clean my panels?

Over time dirt, debris and dust can build up on your solar panels, creating a barrier that prevents the sun from reaching the solar panels. How often your panels need a clean depends on where you live and how dirty they get. 

  • If you are in town and your panels are on the pitch (not flat) then a clean every 6-12 months is usually enough.
  • If you live on a dirt road, near paddocks or have lots of bird or bat wildlife in your area, they will need more regular cleaning. Some may need a clean every couple of months, while others can get away with cleaning every 3-6 months or so.

These times are only a guide – it really does just depend on how dirty your panels are. It is just something to keep an eye on to get the most out of your system.

What does "grid connected" mean?

Grid-connected means that the solar power system is connected to the electricity grid (the Ergon/Energex network) that currently supplies you with power. At night time and in periods of inclement weather, you will be buying power from your electricity supplier if your solar power system is not producing enough power to meet your consumption.
