FAQ
Frequently Asked Questions – Jinko 620W N-Type Bifacial Solar Panel
What makes the Jinko 620W solar panel different from standard panels?
The Jinko 620W solar panel uses advanced N-Type TOPCon technology and a bifacial dual glass design. This allows it to produce more energy, degrade slower over time, and deliver better long-term performance compared to conventional solar panels.
What does bifacial mean on this solar panel?
Bifacial means the panel can generate electricity from both the front and the rear side. When installed in suitable conditions, such as reflective surfaces, the panel can produce additional energy from sunlight reflected onto the back of the panel.
How many of these panels do I need for an 8kW system?
For an 8kW inverter, typically between 12 and 16 panels are used depending on system design, roof space, and configuration. Final sizing should always be calculated based on voltage limits and installation conditions.
Is the Jinko 620W panel suitable for residential use?
Yes, this panel is ideal for residential, commercial, and industrial applications. Its high power output allows fewer panels to be installed while still achieving strong system performance.
How efficient is the Jinko 620W solar panel?
The panel offers high efficiency of approximately 22.95%, allowing it to generate more electricity per square meter compared to lower wattage panels.
What is the advantage of N-Type technology?
N-Type technology reduces degradation, improves performance in high temperatures, and increases overall energy production over the lifespan of the panel. It also reduces issues like LID and LeTID found in older panel technologies.
Can this panel be used with hybrid inverters?
Yes, the Jinko 620W panel is fully compatible with hybrid inverters such as Sunsynk, Deye, Victron, and other systems, provided the system is correctly designed within voltage and current limits.
Is this panel suitable for coastal or harsh environments?
Yes, the dual glass design and robust construction make it resistant to environmental factors such as moisture, dust, and corrosion, making it suitable for coastal and demanding conditions.
What warranty does this solar panel include?
The panel includes a 12-year product warranty and a 30-year linear power warranty, with low annual degradation of approximately 0.40% per year.
Does this panel perform well in cloudy or low-light conditions?
Yes, N-Type technology improves performance in low-light conditions, allowing the panel to continue generating power even during cloudy weather or early morning and late afternoon periods.
Can I install this panel myself?
No, this solar panel must be installed by a qualified electrician or solar installer. Proper installation ensures safety, compliance, and optimal system performance.
What is the lifespan of this solar panel?
This panel is designed to operate efficiently for over 25 to 30 years, with minimal degradation over time, making it a long-term investment for solar energy systems.
