Is it Worth Adding Solar PV Systems to Dual Occupancy Homes?

Is it Worth Adding Solar PV Systems to Dual Occupancy Homes?

Solar panel technology has come a long way in recent decades, and innovations in solar photovoltaic (PV) systems such as high-performance panels, robust transformers, and greater access and competition have also driven down costs to where it is now relatively affordable for homeowners in Australia.

Is it worth building solar PV systems in dual occupancy homes? There is much to gain and little to lose, so perhaps a better question would be “is it worth it to forego solar PV systems in dual occupancy homes?” In any case, let’s look at some great reasons why homeowners may wish to consider installing a solar PV system on their dual occupancy home:

Clean, Abundant Energy

100% green, environmentally-friendly energy harnessed from the power of the sun is what solar panels are all about. Given that across Australia, adequate sunlight isn’t much of a problem to begin with, why not absorb some of it yourself and turn it into clean, renewable energy to power your home?

Energy Savings

The amount of money saved on energy bills can potentially be quite significant, depending on the configuration and size of your solar PV system. Large systems designed for complete self-reliance, while costly up-front, can completely eliminate your energy bills altogether. Small systems designed to supplement energy drawn from the grid can likewise make a pretty good dent in your energy bills.

Normally, rather than measuring the size of a solar PV system by number of panels, installers measure in terms of kilowatts of output. To give a rough example, a small 1.5 kW cannot likely support a family of four using a consistent amount of electricity day in, day out, but it will supplement their energy consumption by that amount. These systems can cost around $2,500 to install and are a good way to dip your toes into solar energy. For dual occupancy homes, it’s a drop in the ocean, however.

For large homes, businesses, and dual occupancy homes that consume an average amount of electricity every day, larger 10 kW systems can often fully bear the demand without having to draw from grid electricity. These more complex systems require more roof space and can cost upwards of $12,000.

How Much Will I Save?

Consider that throughout the lifespan of the solar panels, your home is generating FREE energy. Once the capital outlay has been recouped (usually in around 7-10 years), every single watt generated is essentially completely free.

Is it Worth Adding Solar Panels to a Dual Occupancy Home?

Property owners and investors considering solar PV systems for dual occupancy homes should do more than simple napkin maths and speak with a renewable energy expert to ensure that their needs can be met with a fantastic, green solar PV system suitable for one or both homes.

In almost all regards, the answer is a clear “yes,” although the big consideration that holds many homeowners back is the initial capital outlay. You’ll need to be able to pay, up-front, for the entire cost of parts and labour, which can be thousands or tens of thousands of dollars with a payback period of up to a decade.
