Why Solar?

Solar, unlike coal power is the actual future of Australia and is fast becoming the now!  With more and more households installing solar and taking advantage of the energy provided by the sun it’s becoming easier to access. That’s not to say there is zero downsides to solar, but the benefits far outweigh those.

We have politicians in this country holding up lumps of coal and telling us not to be afraid, which I find disturbing. I grew up in coal country, the La Trobe Valley in Victoria, with multiple open cut coal mines in the area, my father even worked as a dozer driver for them.

We knew even as kids that coal had a negative impact on the environment, yet somehow in the last thirty years, it has become nice, according to our current government.

 

Reducing your footprint.

Not being part of the grid, removing ourselves from using fossil fuel as power is one step closer to us making an impact on reducing our carbon footprint. This is something everyone can do, even a small system on a suburban household helps to reduce usage during the daylight hours.

We all need to be responsible for at least trying to reduce our footprint, solar power is one of those ways, it may not be viable everywhere in the world, but for us in Australia, our climate is well suited to solar power.

Obviously, this works best in conjunction with other environmentally friendly endeavours, composting, re-using, buying environmentally friendly where possible etc.

 

Reducing your costs

Having solar installed is a costly process, with anything from a few grand for a small system all the way up to 30K plus for a large off-grid system.  This cost is offset by the fact that you will no longer have to be reliant on grid power, and for a standalone system, no longer need to pay quarterly electricity bills.  It may take a while to break even, but when you think about the many years after you’ve broken even that you will still require electricity, it makes sense.

For us, we got a quote to have grid power on the block  The estimate to put a pole across the highway so that they could then put poles to the house was $30,000. Once we heard that, it wasn’t even a choice, we could get a system that would run all we need for that or less, so that’s what we did.

There are ways to reduce the costs of a new system.  We purchased second-hand panels.  We bought them from a reputable source and we tested them prior to purchase.  We have had no problems with the panels, and would definitely recommend this as a cost reduction.

We chose not to skimp on our main battery bank or charge controller/inverter.  We needed to make sure that we could rely on these every step of the way, especially with 6 small children.

Our charge controller/inverter board was purchased from Energy Connections we received it all pre-wired, ready to install. For a very reasonable price we got a fully functioning Victron board, wired by electricians that will see us out for many years.  Our batteries were also purchased brand new, this was by far the most expensive part of our entire system.  By doing this though, we know that these batteries if handled correctly will last us 20+ years.

In the case of these two items, our decision to pay more now, means that we have peace of mind for the long term.

Being power aware

Installing the Solar

We have all seen the campaigns over the years for turning lights off when leaving rooms and not leaving electrical items on standby. Until we moved off grid though, we did not truly realise how much power we wasted each day.  We now see exactly how much we are using and are far more aware.

This has taught us the benefits of being spend thrifty with our power.  We purchased a low wattage pressure pump for our water and have only one tap hooked up,  we chose not to install lights into the bedrooms, as these rooms are purely for sleeping and we don’t leave anything running unnecessarily.  We have minimal power points and change what is plugged in as we need it.

We make sure to choose what we use carefully on rainy days, knowing that our input will be lower and overuse might mean that we need to kick in the generator to top up the batteries if they start to fall toward 70% capacity.

Even something as seemingly simple as air-conditioning.  Previously, before it would start to get hot, we would turn on the aircon. Now, because of the high-power usage of most air-con, we open doors and windows. Though with our current setup, we would be able to run a good quality inverter split system.

With our current setup, we have almost unlimited power availability during the day.  At night, however, we have to be more aware.   We purchased inverter fridges and freezers and we make sure to turn everything off that is not in use.  We still have plenty of power, but it is coming straight from the batteries.  It would be easy to run them under 70% if we were not being thoughtful about our usage.

 

So, it’s just better than being on the grid

Whilst solar power may incur a larger cost up front, in the end, it will pay dividends.   Not only in money saved, but also in environmental impact, and reducing wastage. We, unfortunately, live in a society where waste is the norm. Society will not be able to continue indefinitely without change.  Starting with small steps, and leaving smaller footprints is a way that everyone can contribute to our future.
