Solar Panel Installation Cairns

Finding what solar power system size you need goes off household energy consumption, available roof space and budget. However, if there is no space and/or you cannot afford a larger unit, sizing will depend on your electricity usage during daylight hours. With that data, you can use an online solar calculator to determine the right size, or you can also contact solar specialists to help you.

Yes, solar energy can be stored for night usage and even on rainy or overcast days. However, installing a large solar system when your energy consumption at night is high will be ineffectual. Our team can advise you on some changes to lower your night usage and recommend batteries. If you need help determining how much energy you are using at night, contact us.

In Cairns, main electricity retailer Ergon Energy charges a household $0.29 per watt/hour and pays $0.09 per watt/hour for any excess power generated from the solar power system. This means that you will need to produce roughly three times the amount of energy you use to break even.

Whether you’re under Ergon Energy or have a different provider, we will be more than happy to help you calculate how much you can get paid for your surplus solar energy.

Solar panels continue to become better and better, but in saying that, you still need to look out and only buy well-known brands with a good reputation. This way, you know the company will be around for the long term.

The brand of solar panels we use is called Canadian HiKu 370W panels. These panels come with a 25-year product and a 25-year limited performance warranty. Canadian Solar is a reputable brand that has won awards for its new energy work and quality performance, with customers in over 150 countries.

The 25-year product warranty for our Canadian Solar-branded panels covers customers for any cracks, delaminations, fading, tarnished frames, and glass breaks.

For the 25-year limited performance warranty, it covers customers for the efficiency of the panel. The efficiency is calculated over 25 years, and if it drops below the calculated figure within that period, they will replace the panel.

The general lifespan of solar inverters for residential applications is about ten years. If you are curious about their warranties, inverters generally come with a 5-year warranty, which covers the performance of the inverter and its components. It also covers any damage due to poor manufacture.

Some of the inverters we use at Easy Cool Air are Canadian Solar, Fronius and SMA, which have a 5-year warranty. SolarEdge inverters, meanwhile, have a 12-year warranty and an extended warranty option (up to 20 years).
