Don’t Get Lost in the Detail


 

This article explains what are the components of a solar system and which one is best for you.


 

Panels

According to Finn Peacock, the man who literally wrote the book on solar there at two types: polycrystalline or monocrystalline. And which one is best?

 

According to Finn, “It doesn’t matter which one you choose. What matters is that you buy a good module brand that will last 25+ years on your roof.”


 

Refer to Article 1 for a list of the brands you can trust.


 

Inverters

The inverter converts direct current (AC) into alternating current (AC) so it can be fed into you home or the grid. There are two types:

 

1. String

A single inverter for all the panels installed in the wall of your house

 

2. Micro

Installed on the back of each individual solar panel. So if you have 20 panels you have 20 micro inverters.

 

Micro inverters cost about 20% more but they optimise each panel individually so they should produce more energy. This is ideal where shading might be a factor on your roof.


 

Refer to Article 1 for a list of the brands you can trust.


 

Pro Tip: Spend your extra dollars on the inverter(s) before the panels. According to Finn, this is where performance varies significantly according to brand. Good inverters will last 10 - 15 years, bad inverters will last a year and pose a fire hazard.
