2. Factors affecting the cost of solar panels
The size of the solar system: the size of the solar system will also affect the cost of solar panels, for example, a 5KW solar power system compared to the 10KW system, the cost of the 10KW solar system will be higher, but the larger the solar system, the higher the percentage of the electricity bill can be offset. Therefore, installing more kilowatts of solar panels equates to more savings on your electric bill, but at a higher upfront cost.
Technology used in solar panels: For different manufacturers of solar panels, the technology they use to produce the panels can vary, which affects the cost of the solar panels. For example, if JA Energy uses PERC technology in the production of its solar panels, then the price of JA Energy is significantly higher than other manufacturers.
Installation Difficulty: Installers install solar panels on some more complicated roofs or floors, which requires higher installation skills and technical requirements from installers, thus affecting the cost of solar panels.
3. Tier-1 and Tier-2 brand solar panels
Tier 1 brand refers to solar panels that are superior in terms of quality, quality, performance, etc. and outperform other solar panels on the market, such as LONGi, Trina, Jinko, etc. These brands usually have a longer history of use.
