Based on the different materials and manufacturing processes, solar panels are mainly divided into the following types:
(1) Monocrystalline silicon solar panels (Mono-Si)
Features: Made of high-purity monocrystalline silicon, the cells are uniformly dark blue or black, and the efficiency is the highest (20%~24%).
Advantages: long life (more than 25 years), high space utilization, and good high-temperature performance.
Disadvantages: high cost and high energy consumption in the manufacturing process.
Applicable scenarios: rooftop photovoltaics and high-power demand projects.
(2) Polycrystalline silicon solar panels (Poly-Si)
Features: Made of multiple silicon crystals, the surface is blue and spotted, and the efficiency is slightly lower (15%~20%).
Advantages: low cost and simple manufacturing process.
Disadvantages: low efficiency and rapid performance degradation at high temperatures.
Applicable scenarios: small and medium-sized photovoltaic systems and installation projects with limited budgets.
(3) Thin-Film Solar Panels
Features: Made of materials such as amorphous silicon (a-Si), cadmium telluride (CdTe) or copper indium gallium selenide (CIGS), with a thickness of only a few microns.
Advantages: Lightweight, flexible, excellent low-light performance, low production cost.
Disadvantages: Low efficiency (10%~13%), short life (10~15 years).
Applicable scenarios: Building-integrated photovoltaics (BIPV), portable solar equipment.
(4) Emerging solar technologies
Perovskite solar cells: Laboratory efficiency has exceeded 33%, low cost but stability is still being optimized.
Organic photovoltaics (OPV): Flexible and printable, suitable for wearable devices.
Concentrated photovoltaics (CPV): Using lenses to focus sunlight, the efficiency can reach more than 40%, but it requires precise tracking of the sun.
