One of the most promising renewable energy technologies is photovoltaic. Photovoltaic (PV) is a truly harmless on-site power generation method that generates electricity directly from the sun without worrying about energy supply or environmental hazards. These solid-state devices only generate electricity from sunlight, silently, maintenance free, pollution-free, and do not deplete materials.
As a key material that affects the conductivity of solar cells, the height, width, quantity, and other factors of solar cell grid lines will determine the photoelectric conversion rate of solar cells.
RV travel is a popular way of traveling nowadays. With the development and progress of solar technology, the energy demand during travel can be combined with solar panels to reduce power anxiety on the road.
What is EVA film？
EVA is a thermosetting adhesive film used in the middle of laminated glass. It is a functional film made by adding crosslinking agents, coupling agents, and UV resistant agents to a resin based on ethylene vinyl acetate copolymer.
Many customers find it strange why solar panels with the same appearance have vastly different prices when choosing them? Some solar panels only cost 3 yuan/watt, while others cost nearly 20 yuan/watt. What is the reason for this huge difference?
The parameters of solar panels are provided by the manufacturer under STC (Standard Test Conditions). At STC, the corresponding solar radiation is 1000W/m2, the operating temperature of the battery is 25 ° C, and Am is 1.5.
Solar panels are very durable, and leading brands now offer them a 25-year product warranty. They can also save you thousands of dollars in electricity bills throughout their lifetime, while their upfront costs become very small. However, only by correctly installing solar panels can good results be achieved.
Understanding the grading system
For solar panel manufacturers, they often hear terms like “Tier 1,” “Tier 2,” and “Tier 3.”. Tier ranking is a classification system developed by professional organizations.
Flexible components, also known as lightweight components, can be bent by 30 degrees or even more. Its main materials include polyester, polyimide, PTFE, fluorinated polymers, etc.
Material quality
Most photovoltaic modules that accelerate the degradation of solar panels are caused by LID, PID, and backplane failures. These degradation mechanisms are partially caused by material defects, so it can be concluded that photovoltaic modules with higher quality materials degrade at a slower rate.
