|
Initiative |
|
|
Integration methodology |
Integration is not trivial: Soltigua’s experience-based Solar Design Method is key to develop a functioning system
|
|
Crucial Interfaces |
Field performance is important: thanks to thorough and extensive design and tests Soltigua’s collectors provide best-in-class efficiency and reliability
