  • Hello Mark. Very Nice Presentation. Could you please clarify the trade off between the use of thin film modules and higher efficiency mono / poly modules and the impact on BOS costs for this particular impressive project. It will be appreciated if you can share this info. Thanks in advance. Fadi.
