4 Key Factors that Determine What Solar Panels Cost

1. Solar system size affects what solar panels cost

This may sound obvious – make sure your solar system isn’t too big or too small for your home. Your roof may fit 20kW worth of solar panels, but a cheaper 6.6kW solar system may be all you need.

2. Panel Brand affect what solar panels cost

A Ferrari costs way more than a Hyundai, but they both get you from A to B. As in every industry, the quality and reputation delivered affects the price of the solar system.

Cheap solar panels may not capture as much sunlight or tolerate shade as well when compared to more sophisticated options. However, the smaller upfront cost teamed with a lower efficiency panel may still deliver you an excellent return on investment. BUT make sure you don’t get stung by cheap solar panels which are junky and prone to early failure and breakage – that will just end up costing you more.

If you do opt for cheap solar panels, check:

• The product and performance warranties;
• If the manufacturer has service and warranty people on the ground in Australian to help if something goes wrong; and
• Online reviews

Reputable brands with proven track records, great after sales customer service and robust warranties will inevitably charge more. If you sacrifice on price don’t be surprised if it comes at the cost of at least one of these perks.

Here’s an example of 3 brands hitting different price points:

ÂÂ	What We Love	What We Don’t Like
Top-End	Heavily established and reputable – been around for over 35 years, one of the longest in the solar industry Australian office in Melbourne 40 year replacement product warranty Headquartered in the USA with manufacturing in Malaysia, the Philippines and Mexico	Expect a longer payback period due to premium upfront costs.
Mid-Range	Great value for money Headquartered in Canada with manufacturing in Canada, China, Indonesia, Vietnam and Brazil Higher than average efficiency 25 year product warranty Strong Australian Presence	Lower panel efficiency and shorter warranty when compared to premium brands like SunPower
Budget-Friendly	30 year performance warranty and 15 year product warranty Australian presence	Cheaper materials can be more prone to faults

3. Warranty affects what solar panels cost

Unfortunately, some warranties are not worth the paper they are written on. Be wary.

Lengths, but more so STRENGTH of warranty is extremely important, particularly for a system that is going to be exposed to harsh Australian conditions.

We all know you get what you pay for. Paying a bit more for a reputable brand will not only carry longer warranties, but will also be backed by suitable operations in Australia to honor the warranty if you need it. 

4. Choice of Inverter affects what solar panels cost

The solar panels might seem like the star of the show, but it’s your solar inverter that does a lot of the heavy lifting. It converts the DC energy produced by your panels into usable AC electricity that runs your aircon and washing machine. 

Choose wisely – the inverter is actually the single most expensive component of your system. Your inverter will also have a much shorter warranty than your panels as they have a shorter lifetime. Expect to replace your inverter before you need to replace your panels.
