I’m from Puerto Rico. We have had no power for 4 months now. I must say, Couleenergy’s flexible solar panels have really impressed me! Considering the price, the benefits are fantastic. They have convinced me to go fully solar. However, I have some advice. If you plan a big system, choose larger, high-efficiency solar panels. Why? Two reasons: First, larger panels mean higher efficiency. With a big system, space matters! Fewer solar panels cover the same area. This simplifies installation. Second, high-efficiency solar panels produce more power. You need fewer PV panels to get the same energy. Again, this saves space and installation work.

I bought Couleenergy 330Wp poly solar panels. I installed them on my roof. I am so impressed with the quality! In the past, people worried about “Chinese” products. But these panels are different. The cells align perfectly. The solder joints have no flaws. The lamination is perfect. The junction box and cables are good. The panels are advertised as polycrystalline. But the cells don’t look sparkly. They have a deep blue-black color. They look like monocrystalline cells! These unique panels make me very happy. My thoughts: 1. Excellent quality. 2. Perfect cell alignment. 3. Flawless solder joints. 4. Defect-free lamination. 5. Good junction box and cables. 6. Not sparkly like polycrystalline. 7. Truly unique solar panels.
Couleenergy solar panels exceeded my expectations. I highly recommend them to anyone going solar!

Coulee’s small solar modules utilize microcrystalline cells, allowing them to generate significant power even in shaded areas. Unlike lower-quality amorphous solar panels, these modules maintain power production for 20 to 30 years. The textured surface of the glass covering minimizes reflectivity, while I have observed measurable voltage output just before sunrise. Apart from the sharp corners (which require caution), I find no flaws in their products. PROS: 1. High-quality materials, 2. Superior microcrystalline cells, 3. Fast delivery, 4. Standard connectors. CONS: Sharp corners.

Great value 200 watts solar panels. Not the latest or most artistic, but they perform as claimed. They consistently reach their rated power, even producing over 190+W in winter. These results were not achieved under controlled conditions but in real-world usage, monitored by a trustworthy TM2030 meter. Installation is easy, frames are sturdy, and shipping is fast and secure. Overall, a reliable choice at a reasonable price.
