Successful Project


Success Story: Meeting Italy’s Industrial Solar Needs

Mr. Antonio comes from the ITALY. He talked to our team last month about the SOLAR installation. For his industrial location. Due to the HARSH environment, he needs solar modules which have features. For instance, short circuit current ISC protection. High wind load-bearing capacity. Low Nominal Module Operating Temperature. 

Wait, it does not end here. 

First, we ASKED him about the list of requirements he needed. We even helped him evaluate the requirements such as: 

  • Five 350-watt solar MODULES developed under the latest technology. 
  • Less potential induced degradation solar modules
  • OPEN CIRCUIT voltage VOC protection. 
  • SHORT CIRCUIT current ISC protection system. 

What happened next? It was simple. We started our quest for the perfect solution for our DEAR customer. 

Guess what? We got it and delivered him a highly efficient module he NEEDED. 

Guess why he preferred us? There are many reasons. 

  • Access to a Premium QUALITY Module.
  • Attention to the customer REQUIREMENTS. 
  • Competitive rates
  • After-sale services. 

All these factors have APPRECIATED our business around the GLOBE. 

What our CUSTOMERs say


I am very thankful to the Leeline Energy team. It got me affordable prices for the modules. Open circuit voltage VOC is the feature I love the most. Thank you for such a great solution.

    People Also Ask About 350w Solar Panels

    1. How long does it take to arrive?

    Shipping depends on VARIOUS factors like: 

    · Location
    · Shipping method
    · Lead time for the given product quantities 
    · Manufacturer policy
    · Any peak event or global shipping crisis

    Keep all factors in your heart BEFORE you get a DEFINITE shipping time. 

    2. How do I find which solar panels are perfect for our home?

    Finding solar systems for your HOME depends on your BUDGET. Preference. Quality. And module EFFICIENCY. Advanced module technology with high efficiency will put a HIGH-cost burden on you. 

    3. Does dust reduce the effectiveness of solar panels?

    Yes. It can. A dust FORMS a layer on your solar PANELS. As a result, the LAYER blocks the SUNLIGHT and decreases the module efficiency. So, proper maintenance is ALWAYS the best idea. 

    4. Can I get a solar panel sample?

    Yes, we can get a SOLAR PANEL sample. Test its functionality. And fetch you a DETAILED pros and cons sheet of the given model.

    Speed up the progress of your solar business and make more sales!
