Product FAQ

How many JA Solar JAM72S20-470/MR/1500V panels do I need for my home?

The number of panels depends on your energy consumption and roof area. At 470W per panel, a typical 10kW residential system requires about 22 modules. Use our Solar Roof Calculator to get a precise layout based on your actual roof dimensions.

What is the efficiency of JA Solar JAM72S20-470/MR/1500V?

This panel has an efficiency of 21.2%, using Bifacial, TOPCon, N-type cell technology. Higher efficiency means more electricity per square meter, which is especially valuable when roof space is limited.

Can I get more power from the bifacial JA Solar JAM72S20-470/MR/1500V?

Yes. Since this is a Bifacial module, it can capture sunlight from both sides. Depending on the reflectivity (albedo) of your roof surface, you can see a gain of 5% to 25% in total energy yield.

What are the dimensions of the JA Solar JAM72S20-470/MR/1500V?

The module dimensions are 2112mm × 1052mm × 35mm. Always account for these measurements plus fire setbacks and mounting clearances when planning your solar layout.

Is JA Solar JAM72S20-470/MR/1500V compatible with standard inverters?

Yes, these panels work with most string and hybrid inverters. However, you must check the Voc (Open Circuit Voltage) and Imp (Current at Max Power) against your inverter's MPPT specs.

What warranty does the JA Solar JAM72S20-470/MR/1500V come with?

This panel includes a 12-year product warranty from JA Solar. Solar panels typically degrade about 0.4–0.5% per year, meaning this module should retain over 87% of its original output after 30 years.
