Solar energy is renewable source, it is one of the main source we can get from nature with free of cost. So we can make it to use effectively using the latest technologies.
Solar panel is Photovoltaic module that use light energy (photons) from the Sun to generate electricity through the photovoltaic effect. Solar electricity usage is developing all over the world, so we can also move to that for making alternative to fossil fuels and also reducing the electricity bill.
How to choose the right Solar Panel for your Unit
In current day technologies , we have two main categories of solar panels: Polycrystalline solar panel & Monocrystalline solar panel. Both produces electric energy from the sun light. But both panel has some key differences. Before purchasing Solar Panel to your unit, you need to know about the key differences between them.
Monocrystalline Solar panel
The solar panels made out of this single crystal of pure silicon is called Monocrystalline solar panel. They are made out of the highest-grade silicon and Monocrystalline panels are generally thought of as a premium solar product. The main advantage of Monocrystalline solar panel is High efficiency and range in between 18% to 24% . It has sleeker aesthetics. The price of Monocrystalline panel is higher when compared with polycrystalline panel.
Polycrystalline Solar panel
In polycrystalline solar panel multiple silicon fragments are together to produce the wafer for these panels. For this reason, they are called polycrystalline. These panels have an efficiency of between 13%-17%. Polycrystalline solar cells have lower efficiency and costs less than Monocrystalline solar cells.
Criteria Mono Crystalline panel Poly Crystalline panel
Efficiency High efficiency 17-20% Less efficiency 13-16 %
Design Made of Single silicon cells Made of Multiple silicon cells
Aesthetics Black in color blueish in color
Space Occupies less rooftop space Takes more space
Performance Performs better even in low light Low efficiency in cloudy weather
Price Expensive Relatively low price
Longevity 25+ years 25+ years
