How to effectively manage them to save money and maximize returns

All of our battery solar hybrid systems allow you to take control of your power giving you choice and flexibility over how you use the electricity grid. The large benefit of battery systems is the ability to control your produced energy and when to consume it.

The main aim of a solar hybrid system is more self-consumption of solar-generated power and less reliance on the grid. When the sun shine’s, you want to consume as much of this energy as possible, as all battery systems come with analytics meters this is relatively easy. Electricity is invisible and it has been hard to understand how much you are using at any one time.

All analytics meters will show the amount of energy being produced, how much you consume and the charge of the battery. By seeing the household energy and managing it well you can save a lot of money. The management is the key.


All our solar battery systems are set to the same consumption protocol operates as follows:

  1. When the sun is shining, the Hybrid inverter directs the solar power in the following order:
    1. To the home,
    2. To the battery bank,
  • To the grid, up to the export limit.
  1. When there is not enough solar power to run the home, then the power stored in the battery will be used.
  2. Power is only used from the grid when there is not enough solar power or stored power to run the home.


With any solar system, the production of energy is a basic function, but its how you use it that matters most. Using simple techniques such as timers will assist in increasing your return on investment.  Not only are they cheap and divert the suns energy to water storage, they also assist the power grid with reducing the overload to the grid and voltage issues from too much exported power. The following is a scenario of a household that has an electric boosted hot water system and a pool.

Hot Water timers

The hot water system can be put onto a timer to heat when the sun shines. During the middle of the day when the solar system is peaking production, your water can be heating from the suns energy. The simple electric boosted hot water system that uses approximately a third of your household energy can be powered by the sun. Best of all its very simple. A DIN mounted timer in your circuit board and a relay costs only $200 when installed at the same time as your solar system.

A more effective way of heating hot water is a Power Diverter that only takes the excess produced energy out of the system so that no energy is purchased from the grid when power is being used or the day is overcast.

Pool timers

Pool timers are not a new concept, but when combined with solar is a very cost-effective way to manage energy consumption. A pool timer should be set twice during the day. Most pools will draw under 1.5 kW of energy. If we set the timer for 9 am through to 11 am, When the pool timer switches off the hot water timer comes on as the solar production is higher and in most cases closer to 5 kW. Once the water is heated by 1 pm, the pool timer comes on for the afternoon until the sun goes low in the sky.


Basic automation

Many new household appliances come Wi-Fi enabled, which can be remotely controlled, or has a timer set.  Some packages also allow appliances to be switched on, if these are enough excess solar energy in the system. Your dishes and clothes can now be washed using excess solar power in your home. When you return home in the afternoon you can have the washing complete.

So during the day if the house is empty the sun has powered the hot water (approx. 7 kWh) and the pool pump (8 kWh) at no cost, and no energy from the grid. The remaining energy produced can be stored in a battery, and in this case a 10 kWh battery will be a good size. An average 6.6 kW system produces approx. 26 kWh in North NSW and South QLD, so 10 kWh should power most average houses through the night with the exception of running air conditioners.

Using a few simple timers, and some newer appliances can get you closer to being non reliant on the power grid. Batteries will charge between the timers, so any excess energy n the system is diverted into storage.

As the sun goes down in the afternoon, household energy consumption starts to increase, and batteries energy is then drawn upon.  As most of the larger appliances, pool and hot water is already consumed energy, its only the basics of lights, cooking, computers/ TV that is be consuming energy in the evening.

If you can manage your energy well, the power grid is now used only as a back up. At the moment we don’t recommend disconnecting from the grid, as it still serves a purpose. As a backup the grid will purchase your excess energy, and you will buy energy when the battery is low. As technology increases the grid can be a source of income, with the introduction of Virtual Power plants, where you can provide your stored energy to the grid when the grid is in demand, at a premium price.

Solar and batteries on their own are good methods in reducing your reliance on the power grid and consuming expensive coal fired power. But equally important is the management of the time of day you consume energy. With good management and the correct battery sizing your household power bills can be minimized and hopefully neutralized.

When buying a solar and battery system from UV Power we assist you with energy efficiency and management. With good management and a good sized battery and solar system your energy costs have been minimized. We are your long-term partners in energy management. Your system has been monitored, so we now have the power to manage your energy methodically and precisely.

I’m excited but a little confused about the new economy of crypotcurrencies . In the era of Blockchain and bitcoin, the newest development is peer to peer trading of solar energy that you produce. The energy produced by our rooftop solar system is about to become a tradable commodity.

Trails are currently underway and in the near future, your stored energy in batteries and excess solar power can be released into the grid and sold for crypotcurrency units called POWR. A unit of POWR is similar in many ways to bitcoin, but instead you are trading in Kwh and the units of POWR.

The platform has been developed by the Australian company Power Ledger which uses the blockchain technology that underpins cryptocurrencies. This will allow households, community organisations and businesses to trade their surplus solar energy with each other at rates that exceed the low feed-in tariffs offered by most utilities.

blockchain systemThe Australian government has awarded 8 Million dollars to develop trials using the Power Ledger platform to trial the system. Origin have also shown an interest and conducting trials. In the area of speculative crypto currency trading the price of POWR has steadily increased in value. Its one thing to speculate on crypto exchanges, it’s another to deal in real tangible assets like your excess power.

This is our focus and the best way to prepare for this is to install a good sized solar system with a battery system.

Imagine a neighborhood, all equipped with solar panels. These houses could produce, store, and trade electricity based on their needs. Some houses would need extra, and some would have a surplus.

A world-first public trial for 80 homes, involving the trading of water and electricity without support from a major grid, is about to commence in Fremantle, Western Australia.

Power Ledger has developed a series of world-leading blockchain energy applications, such as a P2P energy trading application that allows businesses, such as Utilities, to host trading on the Platform. Blockchain technology provides a transparent, auditable and automated market trading and clearing mechanism for the benefit of producers and consumers.

The technology enables the sale of surplus renewable energy generated at residential and commercial developments (including multi-unit/multi-tenanted) connected to existing electricity distribution networks, or within micro-grids. Power Ledger puts the power to manage the energy economy into the hands of consumers, while maintaining the value of existing distribution networks.

Power Ledger allows for each unit of electricity to be tracked from the point of generation to the point of consumption within the building it is generated, or when sold to other consumers, using the local electricity distribution network. Blockchain technology couples a tracked energy transaction with a financial one, making the process of realising the value of renewable energy investments simple and secure. Power Ledger allows renewable energy asset owners to decide who they want to sell their surplus energy to and at what price. Energy traded across the distribution network is tracked providing a secure revenue stream for DNSPs.

Power Ledger’s platform uses the technology to track the generation and consumption of electricity for all trading participants with compliant meters and autonomously settle energy trades on pre-determined terms and conditions.

The result is a win/win scenario for consumers with the end result being a higher return on investment for roof top solar. We have already seen a dramatic drop in prices and returns and this new technology will allow those with battery systems the opportunity to Capitalise on their investments.

We are closely following the progress of power ledger and will keep you updated. To remain in the loop about cryptocurrency energy trading subscribe to our blog


The most common question we are asked about solar is, “How long will it take to pay my system off???”

As every home is different and people use energy differently there is no exact answer, so we need to assess every house and its occupants  to get a close answer. In most case it’s a educated guestimate but we can give a good indicator whether solar will give you the returns you are looking for.

A solar system produces energy only in the daytime, starting gradually in the morning, peaking in the middle of the day and then declining towards the evening. By managing your consumption around this production curve you will maximize your savings.

Good Management Saves the Most Money

The time of day when you use your energy is a big factor in how much you save. This article will show a few scenarios of saving for a 6kw system for 3 different situations. In most cases you can draw your own conclusions in where you are positioned with these scenarios and give  yourself a basic estimation on return of investment.

How you manage your energy usage is the number one factor on how much you save. The more energy you can consume when the sun is shining, the more you will save. The aim is to consume as much of your home made energy as possible. Selling back to the grid will be necessary if you are not consuming everything you produce, and feed in tariffs are a lot less than your purchase price. It makes no sense to sell a majority of your power for 10 cents and buy it back at night for 28.6 cents. So good management is vital to maximize your savings.

Solar Finance Scenarios

The following 3 scenarios are based on the cost of power being 26c per kwh plus GST, totaling in 28.6 cents per kwh.  Cost of the 6kw system installed using a mid price system was $6000. Production amounts are based on averages over the entire year and all consumption figures are based on average usage figures. Production varies according to the seasons, in Summer the system produces more energy than in Winter. These scenarios are based on average figures for offering ideas and suggestions on payback times only. Please talk to us for a more accurate figure based on your home and usage patterns.

To gather exact information on your systems production, and your consumption we recommend installing a Smart meter that most good inverter companies  manufacturer, or a 3rd party meter and program from Solar Analytics or Power genius. UV Power install these products with your solar system if needed. For the small additional outlay you have complete knowledge of your homes usage and your inverters production. With this data you can gather real time data to assist in managing and maximizing your systems  returns.

SCENARIO 1. Bob Smith
Best case scenario!

Bob is a large energy user during the day. He has gas hot water, swimming pool , dishwasher, washing machine, and runs a home office which has 2 computers, lighting and a small  split system airconditioner. Before solar he consumed 38kwh of energy average per day.

A 6kw system was installed on both a East and West facing roof. Total production per day 26kwh.

Bob is aware of his power production curve and manages his energy consumption around the amount of energy his solar is producing. In most cases everything produced is consumed on site and very little is sold back to the power grid.

26kwh produced and 32kwh consumed through the day light hours. All solar produced is consumed. Weekdays the office is run and weekends all appliances in the home are used to maximize energy consumption.

26kwh x 28.6 cents = 7.43 per day.  X 365 days = $2714 in savings per year. In this scenario bob will pay his system off in 2.21 years resulting in a 45% ROI.

This is a best case scenario and is possible in a few circumstances but unlikely for most of us. It gives an indication of what can be achieved for a standard domestic solar system for a high user of energy throughout the day and who is home 365 days of the year.

SCENARIO 2.  Tom and Betty Jones.
Average consumers in a Brisbane neighbourhood. 

Tom and Betty have a 3 bedroom house with a pool, electric hot water system dishwasher and washing machine. 2 School aged children and Betty works part time 3 days per week.

The 6kwh of solar was installed half on a North facing roof and half on the West roof.

In this scenario we installed a hot water timer to switch the hot water on at 11am to 2pm. The hot water system consumes 3.6kw of energy. The swimming pool timer was set from 9am to 11am, and 1pm to 4pm. A total of 5 hours per day pool pumping was all that was needed to keep the pool in perfect order. The pool filter and chlorinator consumes 1.5kw of energy. On the days, Betty is home all clothes washing is done, computers on and the home office operating, and energy is consumed gradually over the day.

When the kids come home from school there is a small peak of consumption with the fridge opened a lot, TV and computers switched on.

The system as designed with panels facing West. This allows for some additional production in the afternoon to accommodate the extra afternoon usage.


Solar production amount 27kwh per day.  Solar usage amount 15kwh per day.

15kwh x 28.6 cents =  $4.29 per day.

12kwh exported at 10 cents+ 1.20 per day

Total savings= $5.29 per day x 365 = $1930 per year. ROI 3.21 years. And 31% ROI

SCENARIO 3. Kevin & Sharron

Both Kevin and Sharron run a small business and work 12 hour days Monday to Friday. On weekends they are home and use the aircon and home theatre all day. They have no pool and only stand by power running on their massive entertainment system.

We installed a 6kw system on their Northern roof producing on average 28kwh per day. We switched the hot water onto a timer to run between 11am and 1pm.


Monday to Friday daytime usage.

8kwh x 28.6 cents= $2.28.

20kwh exported x 10 cents. $2.00

TOTAL: $4.28 per day x 260 days= $1372


Saturday and Sunday usage.

20kwh x 28.6 cents $4.56.

8 kwh x 10 cents= $.80

Total $5.36 per day x 104 days = $557


$1372 + $557 = 1929 per year

31% ROI or 3.2 year payback.


How You Can Save with Solar

These 3 scenarios give a broad overview of potential savings from a solar system. I prefer to offer more conservative estimates and are more comfortable with estimates based on 4 years and a 25% ROI, to allow for some margin of error, and real world fluctuations with our busy lifestyles. But I hope this gives an indication of how much you can save with solar.

Power prices are increasing, and the price of solar has dropped. The system that this price is based on a is mid quality and priced system,  so we can offer cheaper systems to this and also premium quality systems. Every house is slightly different so prices will vary according to your roof layout, the condition of your meterboard and the ease of installation.


The only way to gain exact return is to have a UV Power consultant to visit and do an analysis of your home, and offer a quote based on what is best for you.

We also offer finance, from as little as $28 per week, leaving you cash flow positive after installing your system. SO the amount you pay on the finance of your system will be less than your would be paying on your power bill.
