Successful Project


Mr. Alexandru needed 36 300W flexible solar panels for his farm

Mr.Alexandru owns a huge poultry farm in Romania. He reached out and explained his energy needs. His concern was efficient solar energy power. His area experiences low light conditions.

After long phone calls, we settled on our high-performance 300W flexible panels. And a 6.8kwh battery to store excess electricity. We finalized the paperwork, and 30 units were delivered to Alexandru’s farm in 2 weeks. Mr. Alexandru called to appreciate our professionalism. He says his farm is now better than ever.

Mrs. Olivia’s 300W flexible solar panel project in Canada

Olivia owns a preparatory school in Vancouver, Canada. She was expanding the school and needed a better power alternative. Since her electricity bills were above the roof.

Our professionals got in touch. Did a short survey. And concluded that 10 units of 300W panels were enough for her desired actual power output.

Olivia now enjoys sustainable renewable energy. She’s cut her electricity bills by over 80%.

    People Also Ask About 300w Flexible Solar Panels

    1. Which solar panel is best for a partial shade condition?

    Monocrystalline solar panels are the BEST for low-light conditions. They feature enhanced cell designs that perform well in partial shade conditions.

    2. How much power does a 330-watt solar panel produce in a day?

    A 330W panel can generate approximately 1.3kWh per day. Or multiply its watt by the hours your home receives direct sunlight. For example, 330W X 4 hours equals 1320 watts.

    3. Do solar panels charge in the shade?

    Yes. However, the electricity produced isn’t enough to meet energy requirements for most businesses. That’s because of the reduced sunlight intensity and the partial shade conditions.

    4. Can a 300W solar panel run a fridge?

    Yes! That’s because most refrigerators run on 300W – 600W electricity. Unfortunately, a 300W panel is only suitable for smaller refrigerators. We recommend 600W panels that can produce enough electricity for huge refrigerators.
