With the recent boom in rooftop solar installations and the issues it may be contributing to the grid (particularly in WA and SA), COMMUNITY BATTERIES (storage located at the distribution level) make a lot of SENSE.

Multiple BENEFITS/value stacks to arise:
- Less curtailment of existing BtM solar PV systems
- Network load shifting (charge during the day in the evening)
- Asset utilisation (batteries better utilised than BtM)
- Delay network upgrades.

DOWNSIDES are that it will not provide backup power and local residents will receive nominal benefits to their energy bill.

With energy independence not a focus in urban Australia. A combination of COMMUNITY and EV batteries appears to be the optimal storage mix of the future.

What mix?
What technologies/chemistries?

Time will tell

Batteries - the next phase in renewable energy investment.

With over 22,000 residential batteries installed (representing 1 GWh of storage capacity), momentum is strong as we embark on the next phase of renewable energy investment - battery energy storage. Household and utility scale systems will lead the way with businesses to follow.

Batteries will be used to 'flatten the curve' by storing the abundance of excess solar generated for use at later times.

At Solar-e we have developed tools to help our customers optimally size battery systems based on their energy profile and objectives (financial, resilience etc). Needs are unique and batteries should be designed around those needs.

Interesting insights

- Energy bill will go down from $2.3k p.a. to $500 p.a.

- Energy draw from grid in the summer months is almost nil due to the abundance of solar energy being generated and stored for use in the non-solar hours. data datadriven solar batteries

Increase in instant asset write-off for solar PV systems

One of the few bright spots (pun intended) for businesses in the current environment is the increase in the Instant Asset Write-Off threshold to $150,000 and turnover of up to $500m until 30 June.  This will increase and accelerate the financial returns for solar PV systems - see table inset. A 99 kW system would certainly fall within this threshold.

If you've been on the fence about making a purchase and you've got the capital reserves - now is the time to join the clean energy transition.

Things to know about managing energy costs

They say people think about energy as they do taxes - uninteresting, complicated and something you can’t do much about. 

Among the many challenges that are facing Australian businesses today (global competition, skills shortages, technological disruption), the rising costs of energy are now at the forefront. Energy prices are at an all time high and are viewed as the no. 1 area of concern for businesses for the next ten years

There is a lot of ‘noise’ in the energy industry: energy bills are complicated and difficult to understand, there are a myriad of supposed ‘solutions’ / providers and significant skepticism as to whether solutions such as solar PV systems actually work.

The good news? There has never been a better time to take control of your energy costs. The declining costs and improvements in technology have made these solutions more accessible and affordable than ever before. There are three main ways to reduce your energy costs:

  1. Get a better deal;
  2. Reduce your energy consumption; and 
  3. Generate your own cheaper energy (e.g. solar and batteries). 

Energy brokers / price

Energy bills are designed in a way that make it very hard for you to compare your options, especially if you are classified as a ‘large’ energy user under a commercial & industrial type contract. Businesses often do not have the expertise, time or resources to invest the appropriate time to compare deals. Services such as those provided by energy brokers however can do the ‘heavy lifting’ for you, at no cost to your business, by canvassing the market and sourcing you a better deal. These include services such as the NSW Business Chamber backed Australian Business Energy (

Energy efficiency

When it comes to the low hanging fruit of energy cost reduction, reducing your usage (energy efficiency) will likely have the biggest impact and provide the best returns. Simple things like behaviour (switching things off when not being used), upgrading to more efficient equipment (lights, machinery etc) and using automation (sensors, timers) can yield significant energy savings and cost reduction. The right solutions(s) for your business typically depends on what industry your business operates in. Businesses with employees between 6 and 20 can access the Business Energy Advice program (, a free program providing tailored energy advice. Alternatively larger businesses can look to engage an energy consultant who can work with a business to review their options. 


Lastly, the flavour of the month, solar PV systems. Do they work, will they save me money? Yes, but they need to be designed and installed correctly. Businesses typically operate when the sun is shining, making them a good natural fit for solar. The tremendous growth in the solar industry however has led to many installers working on projects in which they have limited experience, particularly with respect to commercial solar systems. This can result in a system, which may have cost tens or hundreds of thousands of dollars, not performing to expectations, or in some cases, not working at all. It is therefore important to work with a reputable installer. Important things to consider include: ensure they are a certified installer with the Clean Energy Council, have experience working on commercial projects and have good customer feedback ( google their business name). Alternatively, you can save time and engage an expert to help you with the process.

Does SOLAR SAVE you money? My 6-month post installation review.

You hear about all these claims about solar saving you a bunch of money on your electricity bill. Well here is the data to provide it. These are figures are taken from a residential solar PV system we helped commission and also own in Parramatta NSW 2150.

Key solar system highlights:

- 91% electricity bill reduction

- 4.4 year payback trajectory

- 53% of electricity sourced from solar (clean energy)

- System production exceeded forecasts by 9%

Interesting observations

Energy exported could fully charge a Tesla Model 3 once a week, equating to 17,500 km of driving range or $2,100 saving in fuel costs - all at ZERO emissions!
