When Is The Best Time To Install A Solar System?

While summer may bring an abundance of sun, it’s not the only time of year that solar can save you big. In fact, the surrounding seasons around summer are the perfect time to start exploring your options when deciding to install solar and here’s why!

Solar Panels Need Sunlight Not High Temperatures

In Australia we’re lucky enough to have a high quantity of sunshine hours all year long, meaning solar can reduce your bills in every season! A common misconception is that a solar system is only going to be beneficial to a household in summer, however what you need to understand is that solar panels generate energy through sunlight and not heat. In fact, solar panels actually operate better on a sunny 25-degree day which are common in our Autumn and Spring seasons, as opposed to our 30-40-degree temperatures in summer.

The other benefit outside of summer is that the energy generated from your solar panels won’t be used up running the air-conditioning, which is a necessity in our Australian summers. This means your generated energy can go towards other appliances giving you more independence from the grid. It also means you’ll receive a feed-in tariff for any unused energy that is fed back to the grid.

Lower Demand Can Get You A Great Deal & A Quicker Turn-Around

Outside of summer the demand for solar installations drop as households lessen their reliance on the air-conditioner and see a dip in their power bills, before it’s time to crank up the heat for the approaching winter. During these low-peak seasons solar providers and installers are more likely to offer great deals and discounts for the same high-quality systems that’d cost full price in summer. You’ll also find that unlike in summer the turnaround time from quote to installation can be much quicker, as installers aren’t inundated with installations and visiting sites to quote.

Federal Government Rebate Drops Annually

The current Federal Government Rebate entitles individuals and small businesses to large subsidies when installing eligible small-scale renewable energy systems (under 100kW) such as solar PV systems. The value of the rebate you receive is determined by the rate of STC’s, system size, your location in Australia and the year you purchase. Each year the amount you can claim through the SRES Rebate drops in January until 2030 when the Rebate will be eliminated.

Yearly you’d expect around a 6-8% drop in the value of the Rebate, which you could miss out on by waiting for summer to roll around again.

Tax-Time Is Approaching

As tax-time approaches many Australian’s get excited for their tax payback. Using this lump sum payback to cover the costs of your solar system and installation can set you up for reduced power bills for 20+ years, the average lifespan of a quality solar system.

You’ll be Set Up For Summer

Installing solar in low peak season also means you’ll be set-up and ready to go for summer when sunshine hours increase, instead being put on an installers wait-list during the solar installation peak season.

Understanding Batteries

Off-Grid Systems

For some households a battery system can be of great benefit and minimise a home’s reliance on the grid. However, it’s important to understand for a battery to be useful your solar system needs to be generating excess energy for the battery to store, which you can then use at night or when the sun is not out.

When selecting a battery, you’ll want to invest in a system that is most suited to your home and can drive the best return on investment (ROI). Despite a larger upfront cost, a higher quality battery may significantly increase your ROI.

    Battery systems start from $6,000 and costs can vary greatly based on the following factors:

  1. Cycle Life-Time

    The number of times a battery can fully charge and discharge.

  2. Battery Power (kW)

    How fast it can be charged or discharged.

  3. Storage Capacity (kWh)

    The maximum amount of energy a battery system can store.

  4. Battery Management System (BMS)

    An electronic ‘smart’ system that gathers data and manages the battery ensuring it does not overload or operate outside of its safe functioning zone..

  5. Inverter

    Battery systems require their own inverter if your solar system does not have a hybrid inverter.

  6. 'All-In-One Unit’

    A system which includes the battery, BMS and an inverter all in one unit.

  7. Warranty

    Length of time or cycles the battery system is under guarantee.

  8. Blackout Protection/Backup

    It’s important to note this is not a common feature of a battery system and could cost thousands of dollars to include. Blackout protection not only requires additional components but also a specialised installation and rewiring. For grid-connected homes, the cost for blackout protection can outweigh the benefit.

Additionally, if your purpose for adding battery is to go Off-Grid and become completely independent from the grid you will need to ensure your solar system can generate enough energy to power your home and your battery system is large enough to store this energy. For homes in metro areas going Off-grid is not cost effective and is only recommended for those in remote areas with limited access to the grid. Off-grid solar systems with battery start at approximately $30,000.
