Perth Solar Panel Performance

There are a lot of reasons why Perth is one of the best cities for solar power in Australia –

  1. Perth receives an average of 8 hours of sunshine per year throughout the year.
  2. The city receives 5.8 hours of peak sunshine per square kilometer per day.  This ensures that the solar panels can work at their maximum efficiency.
  3. Perth has one of the lowest payback periods for solar systems in the country. You can read more about power savings here.
  4. Solar panels perth receive one of the best government rebates in the country making the initial investment much affordable.


Module Efficiency & Rating

Solar panels are active solar devices. They convert solar energy to free-electricity by the principle of photovoltaics. There are two kinds of modules: Thin-film, and Crystalline. Rooftop solar plants predominantly use crystalline panels because they are more efficient and therefore better suited to installations like rooftops where space is a constraint. There are two important parameters about solar panels:

  1. Panel efficiency – It should be noted that the efficiency of a solar panel is calculated with reference to the area it occupies. And, usually, 90-94% of panel efficiency is guaranteed under the performance warranty.
  2. Capacity rating – Expressed in Watts(W), this is the power output of a solar panel at 25°C. In short, This rating is the amount of power the solar panel would be expected to produce in 1 peak sun hour. Regen Power offers best-in-class 270 W panels to maximise the production output from solar panels in perth. Due to higher capacity rating of our solar panels, a standard 3kW solar system purchased from Regen power becomes  a 3.2 kW solar system; and a 5 kW system becomes a 5.4 kW solar system. This leads to more energy generation.


Tier-1 Solar Panels

Solar panels in the market are usually classified according to different tiers. This is an inside-the-industry classification, but solar installers have also started using these classifications since the tiers can be correlated to the quality of brand. This list is released by Bloomberg Finance. In conclusion, tier rankings are based on the following main parameters:

  1. Advanced manufacturing processes (use of robotics and automated systems as opposed to skilled labor.)
  2. Investment in R&D
  3. Longevity of the company
  4. Vertical integration (that is, how much percentage of part production is handled by the company in its own factories. In other words, whether the company is designing and fabricating the panels from the ground-up.)
  5. Production capacity.

These factors can correlates to solar panel performance and durability. Therefore tier-1 solar panels signifies the “best in the business”. And some popular tier-1 solar panels include Jinko, Canadian Solar, Trina and Q-Cell solar panels. But the tier system is not a definitive rule-of-thumb. You can read this in the BloomBerg document itself. This a relative quality factor.

Top Tier-1 Panel Brands

Engineered in Germany, Q-Cells solar panels have manufacturing plants in both Europe and Asia. The plants are fully robotic to ensure maximum reliability and minimum defective modules. Additionally Q-Cells are one of the leading companies in terms of research and development, being among the first to bring out market viable thin film modules. All Q-Cells solar panels make use of Anti-PID (Potential Induced Degradation) which minimized yield losses over a their life time.

With over 11 years of expertise, Canadian Solar is one of the three top solar module suppliers in the world. In 2011, Canadian Solar was  the main module supplier for the world’s largest solar installation in Germany totaling more than 166 MW. Canadian Solar has shipped over 4 GW (equivalent to 800,000 residential solar installations) to customers in over 50 countries.

 Jinko Solar Panel has claimed No. 1 global solar module maker position in Q1 2016 and completed numerous commercial installations including the new 1.8 MW solar farm (Alice Springs) and 20 MW Royalla Solar Farm (Canberra). Jinko is a well-known brand with a very large presence in Australia. They are a long standing tier one manufacturer.


Panel Warranties

There are mainly two warranties that for solar panels. They are:

Product warranty – during which the product are replaced in case of malfunctions. Usually 10-12 years. This warranty is similar to the warranty all your electronic equipments possess.

Performance warranty – where the company promises a particular output range over a period of years. Usually this warranty period is 25 years. The below image shows Q-Cells warranty.

At least 97% of power guarantee is there during the first year. Thereafter a maximum of 0.6% degradation per year. After 25 years, solar panels will be delivering at least 83% of their initial performance.
