Thinking About Going Solar – Heres 6 Reasons Why

by | 27 Feb 2018 | Solar Warehouse Australia Blog

Solar systems are becoming increasingly popular for a number of reasons, from rural communities to large-scale industry. Making the choice to switch to solar first hinges on finding the reason that resonates with you, before doing research into suppliers, products, size and more.

1. The lowest bills you’ve ever seen
Aside from the upfront cost of your system and installation, your electricity bills will drop dramatically, if not disappear entirely, once you switch to solar. Besides, the cost of the system will be paid off in the amount you’ve saved, on only a few short years. After that, you can enjoy totally free or dirt cheap energy for the remainder of your system’s 25+ year lifecycle.

2. Excellent ROI
Think of solar as an investment, and you’ll quickly see that it offers some of the best ROI around, compared to more traditional methods. Whether you’re thinking of selling in the future, or want to enjoy the free power yourself, it’s a smart move to jump on the solar bandwagon soon.

3. Free from inflating costs
When you receive power from the grid, you’re entirely vulnerable to fluctuations in the cost of that power. You have no option other than to pay whatever amount is set. By installing a solar system and remaining independent, you can rely on your own power source, and be free from rising electricity costs.

4. Increased value to your home
Much like a new roof or a lick of paint, solar panels are extremely attractive to homebuyers. What’s more, you can actually enjoy the benefits before it comes time to sell, unlike other upgrades for which owners often wait until just before it goes on the market.

5. Eco-friendly
It’s no surprise that solar panels are a green choice. By using energy from the sun instead of coal, you’re creating clean, fossil fuel-free energy. In fact, the average system has a similar effect on the environment as planting 100 trees per year. While this might be a personal decision, it can also boost your reputation as a business that is committed to sustainability.

6. Keep up with the competition
Solar’s many benefits have succeeded in placing early adopters ahead. Now, it’s a matter of installing or falling behind.

Why You Should Oversize Your Solar System

Oversizing Solar Systems Generally have 3 components;

Oversizing your solar inverter

Installing solar panels which have a greater capacity than the inverter is known as ‘oversizing’. While it may sound counterintuitive, this method can not only save you money, but it’s also a clever way around some of the Australian restrictions on inverter size that you’re allowed to connect to the grid.
More commonly, the capacity of the panels is exactly matched to the capacity of the inverter. It makes sense in theory, because you’ll never be generating more power than your inverter can handle. In short, you’ll never be wasting power.
But, there’s one big problem with this logic: solar panels rarely generate as much power as you would expect them to, or as their rated capacity advertises. Adding a few extra panels (in fact, you can add panels with a capacity up to 133% of the inverter) can actually dramatically improve your energy efficiency, so that this benefit vastly outweighs the small amount of energy being lost.

Calculating your capacity
To find the total capacity of your rooftop solar system, just multiply the number of panels by a single panel’s rated capacity (in watts).
To find the total capacity of an inverter, just inspect your product. There should be a number, like 3000W or 4000W somewhere on your inverter, or you can research online.
Financial assistance
By oversizing your inverter by 133%, you’ll still receive financial assistance via the solar rebate, which can pay for around half of your entire system. But beware, you cannot receive the rebate if your panel capacity exceeds that of your inverter by more than a third. This is the magic number.

Inverter capacity
Despite having a specified capacity, Australian-designed inverters can safely manage far more energy, and so one-third more is not every going to be cause for concern. As long as the voltage and current never exceeds the limits, which, if properly installed, oversizing never will, then you will have zero problems.
Inverter efficiency By oversizing your system, you can increase inverter efficiency. When panels consistently supply less that 30% of the inverter’s capacity, the overall efficiency falls sharply.
Don’t be tempted to choose a small inverter, thinking that you’ll save money upfront as well as through oversizing. The difference in cost between inverters is minimal compared to the potential energy output, so it makes more sense to choose the maximum inverter size for your location.
