1. The efficiency of Mono solar panel is 15-20%, and the electricity generated is four times that of thin film solar panels. 2. Mono solar panel requires the least space and only occupies a small area of the roof. 3. The average lifespan of a Mono solar panel is about 25 years. 4. Suitable for commercial, residential and utility scale applications. 5. Can be easily installed on the ground, roof, building surface or tracking system application. 6. Smart choice for grid-connected and off-grid applications. 7. Reduce electricity bills and achieve energy independence. 8. Modular design, no moving parts, completely upgradeable, easy to install. 9. Highly reliable, almost maintenance-free power generation system. 10. Reduce air, water and land pollution and promote environmental protection. 11. Clean, quiet and reliable way to generate electricity.Mono solar panels are made from a single crystal of pure silicon. It is also known as monocrystalline silicon because once a single crystal was used to make arrays that provide solar panel (PV) purity and a uniform appearance across the PV module. Mono solar panel (photovoltaic cell) is circular, and the silicon rods in the entire photovoltaic module look like cylinders. Solar panel is actually a collection of solar (or photovoltaic) cells, which can generate electricity through the photovoltaic effect. These cells are arranged in a grid on the surface of the solar panel. Solar panels are very durable and wear out very little. Most solar panels are made using crystalline silicon solar cells. Installing solar panels in your home can help fight against harmful emissions of greenhouse gases, thereby helping to reduce global warming. Solar panels do not cause any form of pollution and are clean. They also reduce our dependence on fossil fuels (limited) and traditional energy sources. Nowadays, solar panels are widely used in electronic devices such as calculators. As long as there is sunlight, they can work, so as to achieve energy saving, environmental protection, and low-carbon work.
