Our guarantee is that you will get value for money solar systems installed safely and properly by competent local tradesmen. Keppel Prince Solar will support our customers long into the future.
We purchase quality components that offer the best mix we can find of quality, performance and price.
We ensure that our installers work safely and to the standard we’d want if they were installing solar on our own homes or businesses.
We started our Solar Business in 2010 and we plan to be here for the long run – supporting our customers and the products we sell and install.
Keppel Prince started looking at a Solar Division in 2010. We installed our first domestic system on May 1st, 2011 and our first commercial system on November 14, 2011. Since then we’ve installed solar onto 1,500 homes and 150 businesses, schools and hospitals across SW Victoria and the Goulburn Valley – totaling over 10MW of rooftop solar.
There are 760 retailers who’ve come and gone in Australia’s solar industry since 2011. We’re not one of them!
KPE is proud to have grown over the years into one of the larger Solar retailers in regional Victoria and we continue to learn from our experience so we can support our customers for many years to come.

Keppel Prince Solar is proud to have been selected by LG Electronics to become part of the LG Solar family. As agents for LG solar panels Keppel Prince Solar can now provide our customers with access to LG’s Peace of Mind that flows from the work they’ve done to position LG as something very special when it comes to solar panels.
It’s true that as one of the world’s premium solar panel brands, LG does cost you more – but there also seven great reasons why you should consider spending extra money when buying a solar system for your home:
As is the case with many electronic devices, when you buy solar you get what you pay for. That’s not to say that there aren’t some lower priced components that are both efficient and reliable… And by the same token, it doesn’t mean that, just because a particular component is much more expensive than other options, then it will perform better or be more reliable than lower cost items.
At Keppel Prince Solar we pride ourselves on the fact that we are continually reviewing the performance and quality of the panels, inverters and mounting frames that we offer in systems that we sell.
Keppel Prince Solar has been a CEC Approved Solar Retailer since 2017
We buy panels from factories where we’ve visited and carried out an assessment of their Quality Assurance systems.
We offer inverters that we know are reliable in the grid conditions that exist in the areas we sell solar into.
And we pay our sub-contract installers enough that they can work to the high safety and quality standards demanded in this day and age.
When you buy solar from Keppel Prince Solar you are also buying the peace of mind that comes from knowing that we’ll be there if you need us!
Keppel Prince Solar has a range of domestic solar system packages that we update regularly as circumstances dictate. Each of these packages details the full system cost and the significant State and Federal government rebates that are available to people buying solar for their homes.
Federal government solar rebate
The Small Renewable Energy Scheme controls the allocation of support payments for EVERY solar system below 100kW in size, installed anywhere in Australia. The scheme works by estimating how much solar energy your system will generate between the year that you install it and the end of 2030.
Keppel Prince Solar sells the certificates created by systems we install to those power companies and we credit the estimated STC sales value off your price when we quote your solar system.
State government solar rebate and loan – the Solar Homes Program
The Andrews government introduced the Solar Homes program in June 2018. It provides a fixed rebate of $1,850 off the price of a “standard” domestic solar system. It is available to both “owner-occupiers” and Tenants/Landlords of rental properties.
There are two qualification hurdles that applicants have to pass to qualify for a Solar Homes rebate:
If you qualify for the Solar Homes rebate, then you automatically qualify for a Solar Homes Interest Free Loan of $1,850. The only qualification is that we have to prove to Solar Victoria that the system we’re installing will save your household more per year than the loan repayment of $462.50.

Being a CEC Approved Retailer comes with standards that Keppel Prince Solar takes seriously. Everyone who talks to us about solar for their home will receive the same considered and calculated approach to working out what is the best solar solution for your home. To do that we’ll ask you for a copy of a recent power bill so we’ve got the information we need to determine:
We’ll discuss the system design with you and, depending on your address, we’ll look at your home using aerial or satellite photography and assess which of your roof spaces are most appropriate to install solar onto. In many cases we can be confident about what panels we can fit onto which roof space.
We’ll also apply for a connection pre-approval for your address from Powercor so that there are no surprises after you’ve committed to buying your solar system. As you will see, Feed-in-tariff revenue is an important part of the financial benefit for most homes with solar in regional Australia. Unfortunately, you can’t take it for granted that Powercor will allow you to export your excess solar power into the grid if there is already an excess of solar installed in your neighbourhood.
We’ll then insert all of that information into a very smart piece of software that models how much the solar system would have produced each half hour over the same 12 months and values the solar energy according to what would happen to it:
At the end of that process we’ll have a report that provides an accurate assessment of the benefit the proposed solar system will bring by way of lower power bills once the system is installed and working.
Depending on circumstances and your requests, we may provide reports for 2 or more options (larger or smaller solar systems) so that you have the information you need to make an educated decision about which system you should buy.
Being larger users of electricity, many businesses pay a lot less for their power than households, so our task when designing solar for commercial buildings is slightly different. The focus of our efforts for commercial solar are to design a system that as much as possible, matches what the solar system generates through the day with what the site consumes – to maximise the financial benefit for the business.
Again, we’ll go through the process of obtaining consumption data every half hour over the past 12 months for the site, and we’ll model a number of different sized solar systems to identify the best outcome for the business involved..
Our task when designing off-grid solar and battery systems for a home or business is much more about assessing three key factors:
Once we know how large the array, inverters and batteries have to be then we can present options to the site owners for where the array of panels can best be located, where the inverters and batteries should be located, and finally, to provide a firm quote so that the project can get started.
Unlike solar hot water systems which take heat from the atmosphere to heat up water, Solar PV systems convert the energy in light into electricity through a conversion reaction which occurs when light is absorbed by the cells in a solar panel.
The cells are chemically treated slithers of a silicon crystal which give off electrons when exposed to (sun)light.
It is a relatively simple process that involves no moving parts and, with some care, should be a reliable source of electricity for you for over 25 years.
The stronger the sunlight, then more electrons are shed and the higher the amount of electricity generated. Because the cells live in a harsh environment and are continually shedding electrons, their daily production capacity will slowly decrease by between 10 and 20% over 25 years.
The panels produce direct current (DC) electricity which is converted to alternating current (AC) electricity (matching the Grid) within the circuits in the system Inverter.
As you might expect, because the system performance relies on sunlight being absorbed by the silicon cells, a solar system will produce far more electricity in the summer than in the winter – when skies are typically cloudy and the sun is lower in the sky.
Just how different can be seen in below, a typical estimate of average daily power production from a 6.6kW solar array in the Portland area:
The “industry standard” for household grid connected solar is a 6.6kW DC array feeding DC power to a 5KW inverter that then feeds AC power to either your house or the grid. In Victoria homes connected to the single phase grid are restricted to a maximum 5kW export to the grid.
Because of the way electrical grids operate, when you are generating power it will be consumed by your household first, before any excess power is exported to the Grid. The power you export will most probably be consumed by nearby neighbours in your area.
Similarly, when your solar PV system is not generating electricity and you require power, you will draw your electricity from the Grid.
Because your solar system is connected to the Grid, if the grid goes down or is out of specification, your solar system will also shut down – so there is no possibility of your solar feeding power into the street whilst repair workers are working on the wires.
Having analysed over 2,000 homes energy usage over our time in the industry, our experience is that, with their normal consumption patterns, most households in rural/regional Victoria will struggle to use more than 40% of the electricity their solar systems generate. 25%-30% is more likely the self-consumption ratio for most of our customers.
Because so much solar energy is routinely fed back into the grid from solar systems, there are some locations where Powercor is restricting the amount of export back into the grid for prospective new systems.
Summing that up, homes with solar benefit from their self-generation of electricity through two avenues:
Typically in 2020, assuming you are allowed to export to the grid, the total benefit generated by a 6.66kW solar array in SW Victoria is in the range $950 – $1,400 per year depending on how much is self-consumed and what people pay for their electricity from their supplier.
Provided you qualify for a Solar Victoria rebate, expect to pay around $4-5,000 for a standard 6.66kW grid connected solar system depending on which brands are supplied in the system.
For commercial sites thinking about solar, you can budget on spending around $1,000 (ex GST) per kW of solar installed onto your roof. With larger systems (bigger than 30kW) the cost can reduce to around $850-900 per kilowatt of solar installed.
As the name suggests, Hybrid systems are a mix of grid connected and battery fed solar.
A hybrid inverter has the added benefit of being able to feed electricity into a battery or energy storage during the times when your system is generating more power than your home needs. In South West Victoria, most 6.6kW solar systems can charge a 6.5kWh battery throughout the year. In the Goulburn Valley – where there is more sunshine – they’ll charge a 10kWh battery throughout the year.
Then, after the solar system has shut down in the evening and until the sun is up in the sky next day, the hybrid inverter will draw electricity from the battery to meet demand in your home. You will only buy power from the grid once the battery is run down or when your demand levels exceed the capacity of the inverter and battery.
One advantage that Hybrid inverters provide is that they are configured to isolate themselves (and your home) from the grid during a grid outage. If there is a grid outage, the hybrid system can provide limited back-up power to that isolated emergency circuit and keep your home running with limited power. Typically you would have some lighting, the fridge and some power points available to you.
The hybrid inverters we supply will continue to run your house and charge the battery for as many days as a grid outage lasts.
Typically in 2020, assuming you are allowed to export to the grid, the total benefit generated by a 6.66kW solar array tied to a battery around 6kWh in capacity in SW Victoria is in the range $1,300 – $1,800 per year depending on how much is self-consumed and what people pay for their electricity from their supplier.
Provided you qualify for a Solar Victoria rebate, expect to pay around $13-14,000 for a standard 6.66kW grid connected hybrid system with ~ 6kWh of storage capacity, depending on which brands are supplied in the system.
Given that lithium batteries should have a life of 15-25 years, a payback period of 7-8 years for a hybrid system can be an excellent investment as well as bringing Peace of Mind to your household in areas where the grid is prone to regular black or brown-outs.
With the push from Power Distribution Networks to limit expansion of already stressed systems, a solar micro-grid energy storage system is increasingly becoming the norm for anyone building in rural and remote areas.
When you combine 6 and 7 star building designs with individual panels making 400W and more these days, it is possible to build a reasonably compact array capable of generating all of the electricity needed to power a modern home as if it was connected to the grid.
35-40 panels on either a ground frame or a shed roof is enough to power most homes.
Around $40-45,000 is a good starting point to budget for a complete off-grid system as an alternative to paying for an extension to the distribution network.
