Quality Solar Panels

We buy our panels by the container load and pass the savings on to you

Solar panels are organised into Tiers. The Tier 1 ranking scale is orchestrated by Bloomberg New Energy Finance and is used to rank solar panel manufacturers in terms of their bank-ability or financial stability.

There is no doubt you should choose a Tier 1 solar panel manufacturer. But how to choose between Tier 1 panels?

All quality Tier 1 solar panels have the same warranty, and all quality solar panels produce the same output per watt. However, some panel manufacturers are bigger, more financially stable and more integrated than others. We only purchase panels from quality manufacturers who are in the top 10 manufacturers by volume.

However, shipping a large volume is not the most important criteria. Actually, if a solar panel manufacturer gets too big too quickly, they can fall over. But it is difficult to identify the financial stability of even the largest panel manufacturers. That is why quality is also important. The key words are quality and volume.

The things you need to think about with regard to solar panels are:

  1. The price per watt of the panel. Each solar panel should produce at least 295W.
  2. The stability and size of the company. The manufacturer should ideally be in the top five manufacturers worldwide by volume.
  3. The power tolerance of the panels - should be at least +5%. (more is better). This means that the panels will produce 0 - 5% more power than their rated label states.
  4. The Temperature Coefficient of the panels - the Temperature Coefficient of max power should be around -0.4% or less (less is better). This means that as temperature goes up the panels do not lose as much power production as would a panel with a higher temperature coefficient.

Canadian Solar Panels

Please note that the Canadian Solar panels we supply are one of the highest quality Tier 1 panels available in the world and they have great yield, power tolerance and a better temperature coefficient of max power than many competing solar panels that are readily available in New Zealand.

McNae Electrical Solutions currently offer 300W black frame Monocrystaline panels as standard on all our installations.
