Product Q&A

Q:Q1: What are these solar panels made of?

A1: They are monofacial monocrystalline solar panels with half-cell design. The power range covers 650W to 670W and the highest efficiency reaches 21.6%. This structure reduces internal power loss and helps produce more electricity.

Q:Q2: What does monofacial mean?

A2: Monofacial means the panel only generates power from the front side. It is a cost-effective choice for most rooftop and ground solar projects compared with double-sided solar panels.

Q:Q3: Where can these solar panels be installed?

A3: They are widely used on residential house rooftops, factory roofs and ground-mounted solar power stations. They work for both on-grid and off-grid power supply systems.

Q:Q4: What is the advantage of the 1500V system design?

A4: The 1500V DC design allows more panels to be connected in one string. It helps you save costs on cables, junction boxes and mounting supports and lower the total system investment.

Q:Q5: Can the panels work well when sunlight is weak?

A5: Yes. They have good low-light performance. They can still create stable power on cloudy days, early mornings and late afternoons to increase daily power generation.
