Choosing a solar system

What’s important in choosing a solar solution for your home or business?

Well, it really depends on what is important to you.

The most important things to consider are below.

  • Price
  • Longevity
  • Installation quality
  • Performance
  • Payback time
  • Warranty
  • Service

 At Lumax we believe in building solutions for informed customers.

How much should you spend on your solar system to get the best return on investment?

Ask yourself, is the system lasting a long time with a better long term payback,  more important than short term gain through a cheaper price?

Cheaper systems can  sometimes return a payback time that is a little faster  than a higher quality one, (at the start anyway) simply because they are cheaper.

However the problem is,  

  • They  usually don’t  have great warranties or after sales support. 
  • They tend to have issues a lot earlier than a higher quality product.  
  • Have a much shorter lifespan. 
  • Will not perform as well long term. 

             To get a higher quality system can often be a good idea.  At least if you plan to be in the home or business more than a few years.

If you are looking for the fastest payback time and don’t  mind about long term performance.  Spending less may be ok but keep in mind that in the longer term you may have to replace it much sooner than a good quality system.

It’s also a lot easier to get sold a “Junk” system if you are shopping in the budget range so you need to be a lot more careful about who your dealing with.

  • Junk systems result in an absolute nightmare for people, with constant failures.

Some thing else to consider. 

It is also important to keep in mind that spending too much, does not mean you will always get the best return. 

  • Some premium brands can be as much as double the price of other quality solar panels.
  • They don’t always offer anything in the way of added performance or warranties.

Finding a happy medium can be tricky.  

This is why it’s  important to get advice from reputable companies who build solutions, not hard sell you a product of their choosing.

  • How long will my solar panels last?

Solar panels all have two warranties.

  • A “performance warranty” 
  • A “product warranty”.
  •  The performance warranty is usually 25 years,  but is very difficult if not impossible  to claim.
  •  Particularly if the brand does not have local offices in the state or even the country.  

The product warranty is usually 10-15 years for quality systems systems. this means if the solar panel develops physical defects like broken glass or faulty cables it will be replaced.  

Quality brands will always perform better, over a much longer period. Often repaying the extra initial investment many times over. For example tier 2 panels may degrade a double if not triple the rate of a quality brand.

  • What about the inverter thingy?

The inverter is very important on a solar system.  Cheaper brands of inverters can be half the price of their more expensive counterparts but often have superior warranties.  However they are usually more reliable and have better performance.  Inverters are the brains of the operation so if ease of use and reliability is important to you. Its a good idea to get one of the better brands.

Some of the top brands include Sungrow, Fronius, SMA and ABB.


What type of solar panel should I get?

There are many brands of solar panel on the market and  of terms like “tier one” and “high performance” are thrown around alot. But what does it really mean for me the buyer?

There is very large differences in price between panels and they can be simply broken down into three areas.

  • Budget brands.

They are usually much cheaper than higher quality brands and generally do not have offices in Australia. They often degrade much faster than quality brands (despite the warranty promises) but do offer great value in that there is a much smaller investment cost.

  • Quality brands.

These offer trusted long term performance usually with a reasonable price.  They always will have local offices in each state and warranty claims are rare.  they are the biggest brands in the world as they offer a good medium between quality, performance and price. Examples of these are Longi, Seraphim and Canadian solar.

  • Premium brands.

If your looking for the best and don’t mind a higher initial investment. These brands offer the highest efficiency, best  long term performance and after sales service. the downside is you will pay a higher initial investment in return for long term high performance. Examples of these brands are Q-Cell, LG and Sunpower.
