While Rockys Solar are happy to quote alternate panels on request, Rockys Solar generally recommends and quotes for installation of the following solar solar panels for our Gippsland solar installations.
Solar Panels for Gippsland Conditions
Panels installed by Rockys Solar are ideal for use in areas like Gippsland due to their excellent performance in low-light and their tolerance in high-heat conditions. In reality, solar panels spend little, if any, time in the perfect conditions of the testing chamber under which their nameplate ratings apply so performance in realistic conditions is an important consideration.
Jinko Solar Panels installed by Rockys Solar
Jinko Solar panels offer the best value for money according to combined testing by the CSIRO and Choice Magazine. Jinko Solar panels were one of only two to score over 90% with an “excellent” performance rating. Taking price range into consideration, the Jinko Solar panels far outperformed its competitors.
The only panel to rate higher in performance than Jinko Solar was also 70% more expensive. In addition to lab testing, long term outdoor tests were performed by installing each of the solar panels in a field in NSW where they were exposed to Australian weather conditions and their performance monitored side by side for a period of 12 months.
Jinko Solar employ stringent testing including mechanical robustness which is vital for use in Australian conditions. Jinko Solar panels are ideal for use in areas like Gippsland due to their excellent performance in low-light and their tolerance in high-heat conditions.
The Jinko 360W PERC (Passivated Emitter and Rear Cell) Solar Panels included in this proposal have a high energy density per square foot and perform well under low-light conditions and in high temperatures. The PERC technology incorporated into the panels results in increased efficiency due to addition of an extra layer at the rear of the cell. Not all light is absorbed by non-PERC solar cell, with the additional layer incorporated into the PERC panel, some of the light that would be have been unabsorbed is redirected back into the cell resulting in higher efficiency and less wasted energy.
Jinko have invested significant resources in research and development into PERC technology and have implemented industry-leading testing on their solar panels to avoid issues of of LeTID degradation ensuring their solar panels are of the highest quality.
This panel is a monocrystalline panel. Mono panels are cut from a single crystal ingot and are more efficient than polycrystalline (Poly) panels, with improved performance, better production at higher temperatures, and a lower rate of light-induced degradation over time.

Seraphim Blade™ 300W Mono PERC Panels
The Seraphim Blade™ is a monocrystalline panel. Mono panels are cut from a single crystal ingot are more efficient than polycrystalline (Poly) panels with improved performance, better production at higher temperatures and a lower rate of light-induced degradation over time.
The PERC (Passivated Emitter and Rear Cell) technology incorporated into the Seraphim Blade™ panel results in increased efficiency due to addition of an extra layer at the rear of the cell. Not all light is absorbed by non-PERC solar cell. With the additional layer incorporated into the PERC panel, some of the light that would be have been unabsorbed is redirected back into the cell resulting in higher efficiency and less wasted energy.
Additionally, the Half Cell technology used in these panels allows for higher yield due to better shading response. When a module is shaded, only one side of the shaded array’s current will be impacted, while the other array will still be functionally producing power. This means when a module is shaded, the affected working areas of Blade™ will be 50% lower than with other panels.

Why use PERC Panels?
First developed in Australia in the 1980s by scientist Martin Green and his team at University of New South Wales, PERC technology adds an extra layer to the rear-side of a solar cell. Manufacturers spent many years focusing on the front side of a solar cell, and less attention was paid to taking advantage of production opportunities from the backside. Incorporating PERC into a solar cell boosts generation.
In order to create a PERC cell, an additional two steps are employed to the standard back surface field (BSF) during the manufacturing process. First, a rear surface passivation film is applied. Second, lasers or chemicals are used to open the rear passivation stack and create tiny pockets in the film to absorb more light. Manufacturers can approach this in different ways (i.e. varying the recipe for the film and opening technique), but in every instance a dielectric passivation layer is added to the back of the cell.
In employing just two additional steps, the return is threefold: 1.) Electron recombination is significantly reduced; 2.) More light is absorbed; and 3.) Higher internal reflectivity is experienced. Not all sunlight is absorbed through non-PERC solar cells (some light passes straight through). But with a passivation layer on the rear side of a PERC cell, unabsorbed light is reflected by the additional layer back to the solar cell for a second absorption attempt. This process leads to a more efficient solar cell. This is great news for those across the spectrum of the industry.
