Mono vs. Poly solar panels: Which are right for you?


Saving money is one of the best reasons to solar, and whether you choose mono or poly solar panels, you’ll be decreasing your electricity bills. The option you choose comes down to your personal preferences, space constraints, and the financing option you choose.


Personal preferences: If the color of your solar panels is important to you, remember that mono vs. poly solar panels tend to appear differently on your roof. The typical monocrystalline panel will tend to have a darker black color, while the typical polycrystalline panel will tend to have a bluer color. If where your panels were manufactured is important to you, then ensure you know enough about company that made your mono or poly solar panels.


Space constraints: You should prefer higher-efficiency solar panels if your PV system size is limited by the amount of space available on your roof. Because of this, paying the extra cost for more efficient monocrystalline panels that can help you maximize your electricity production will make more sense in these scenarios. Alternatively, if you have a lot of roof space or are installing ground-mounted solar, then lower-efficiency polycrystalline can be a more economic option.

FAQ


Q1: How to choose a right Panel?

A1:Tell us your demand, then our sales will recommend a suitable panel to you.


Q2: What's the different between Mono and Poly panel?

A2:  I Monocrystalline solar panels have the highest efficiency rates since they are made out of the highest-grade silicon. The process used to make polycrystalline silicon is simpler and cost less. The amount of waste silicon is less compared to monocrystalline.  


Q3: How about the delivery time?

A3:  20-45 days for bulk order.


Q4: How to solve the technical problem?

A4: 24 hours after-service consultancy just for you and to make your problem to solve easily
