Locally based, Perth Solar Warehouse provides turnkey solar, battery or EV charger solutions (product & service) direct to customers. We don’t wholesale to alternative businesses.
Solar panel warranties have been divided into two warranty criteria by manufacturers since BP Solar. The two solar panel warranties are as follows;
The most important is the Product Warranty. Product warranties guarantee the overall solar panel integrity when installed to manufacturer specifications.
The second warranty is often the Performance Warranty. Solar panel manufacturer performance guarantees stipulate a nominated performance degradation over time when subject to an installed environment.
Always read your solar panel warranty document to understand the manufacturer’s warranty.
Temp COEF short for Temperature Coefficient, is the percentage at which the performance of a solar panel reduces beyond the module’s Standard Test Condition (STC) temperature point (e.g. 25oC).
That means as the cell temperature increases, the power output by the solar panel will decrease by a nominated percentage.
Generally, the lower the Temp COEF value, the better performance one can expect on a hot sunny day.
Both are monocrystalline cells, however, P-Type cells are Positively charged through boron doping and N-Type cells are Negatively charged through phosphorus doping.
N-Type mono silicon cells posses a slight efficiency advantage over P-Type mono silicon and therefore is present in most high-end modules competing in the superior efficiency race.
HJT or Heterojunction Technology is the (not-so) new solar cell superpower gaining traction after the now Intersolar Award-winning REC Alpha series broke records upon release in 2019 and again in 2022 with the lead-free REC Alpha Pure.
The best of both worlds, consider HJT a hybrid between N-type monocrystalline and amorphous silicon cell architectures.
Beyond outstanding efficiency, HJT possesses a phenomenal Temperature Coefficient at -0.26%oC. Almost half a percent better than the mainstream premium module brand average. HJT is a cell technology ideal for Australia’s warm sunny climate.
It’s easy to be confused when researching solar. With most solar panels in 2024 possessing a 3.2mm glass composite (glass-laminate or glass-glass), the weight of a solar panel is often directly proportional to the technology inside.
- Most often, less efficient panels weigh more (Watt for Watt).
- 440W vs 475W (equal efficiency): Bigger panel dimensions weigh more, they’re not more advance.
Cut through marketing spin using the weight of a solar module.
