How to choose the best solar system
The cost of solar panels is just one of the factors you need to consider when selecting a solar system to install. We want to help you make the right decision about solar energy, which is why we’ve used our experience to put together this handy buying guide. To choose the best solar system for your home, you’ll need to consider the following factors.
To reduce or even eliminate your power bills, you want to get the most solar generation for your money. Therefore, you need to look at the energy a solar system produces over its lifetime and whether this output will be enough. For example, an average-sized family living in a three-bedroom home typically uses 12 kWh to 18 kWh of energy a day. Depending on the amount of direct sunlight your property receives in a day, on average, a 1 kWh power system would help to generate between 4-5 kWh per day.
The performance of your solar system is vital. The higher the efficiency of a solar system, the more watts of electricity you will receive per square metre of panel. Unfortunately, high-efficiency panels do tend to cost more. If roof space is at a premium for you, then go for higher efficiency modules. If two solar panels are priced the same, but one has a higher efficiency; then that module provides better value for money.
There are some very cheap solar systems in the market, but these deals often hide the low quality equipment and workmanship provided. There is the old saying, “You get what you pay for!” Always choose a solar system made with quality components and ensure that it has met Australian and international standards. Some of the high quality solar panels we recommend at Sunrun Solar are LG, Sunpower, REC, Winaico, Canadian Solar and Jinko.
Take note of the warranties and guarantees that are offered with a solar system. It is beneficial to insist on a manufacturers warranty (or “product warranty”) of at least ten years. This is different to the 25-year “performance guarantee” that nearly every solar panel now carries and will cover you should anything go wrong, or you need assistance from the manufacturer.
Its vital that the manufacturer of your chosen solar system has a local sales and technical support office to make it easier to gain support for your warranty should you need to make a claim or seek help. This will save you a lot of time and effort in the long run.
