REC 400W Solar Panel 132 cell REC400AA-PURE

REC Alpha Pure Black is one of the most advanced and modern panels in the product line of the Norwegian manufacturer. It is a great option for commercial and industrial-scope installations, though you can put it on your residential roof as well. The panel has outstanding design and is protected by strong warranties.

Features:

• 400W output
• 132 half-cut heterojunction cells
• Maximum system voltage: 1000V
• 21.6% efficiency
• Open circuit voltage: 46.0V
• MC4 connectors

Great efficiency for reasonable space usage

REC Alpha Pure Black shows 21.6% energy conversion rate — it’s among the highest numbers in the industry for monocrystalline panels at the moment. High efficiency means that you need less space and less modules to build a system to match your energy needs.

Superb performance at high temperatures

Alpha Pure Black is an example of heterojunction cells technology usage: by adding a layer of amorphous silicon to a cell, REC engineers improved the performance of a module at high temperatures. This makes this panel a great choice for hot areas, like Arizona or Texas. The panel loses only 0.26% of its power for every degree after 77°F.

Improved extreme weather and shading tolerance

The REC panel is ready for all kinds of extreme weather conditions. The module can withstand 7000 Pa of the front load and 4000 Pa of the rear load. Half-cut design gives a module better shading tolerance. The module is equipped with 3 bypass diodes to decrease the impact of shading.

Comes with REC ProTrust 25 year warranty

The panel is protected by the triple 25 year warranty for labor, product and performance if it was installed by REC professionals. Otherwise, you still get a 25 year performance warranty and 20 year product warranty. Alpha Pure Black has one of the lowest degradation rates in the industry: only 0.25%. By the end of year 25 you will still have over 92% of initial power output.
