Project Preparation
Why does everything has to be done in the last minute?
The right time of the year helps to avoid costs!
Are all resources available?
Do we have the latest plans and cut sheets?
When is the material coming? Is it coming?
Procedures – how to reduce costs.
SUNSTALLing the Future
On-site / Off-site Assembly
Possible cost reductions
In certain areas (e.g. desert Arizona) it might help to reduce
heat related injuries
Controlled Environment -> Controlled Quality
Less loose hardware in the field
Possible cost increase
Procedures – how to reduce costs.
SUNSTALLing the Future
Quality control
Measurements
According to manual and blue prints
Correct hardware
Torque schedule
Documentation
Procedures – how to reduce costs.

Overview of a Mounting System
Consists of three interrelated subsystems
(a) Anchoring/Foundation - the method by which the entire mounting system is held in place on
the project site
(b) Superstructure - supports the module mounting components
(c) Module mounting system - components dedicated to holding the PV modules in place on the
superstructure
Mounting system selection influenced by site characteristics including
Environmental conditions
Site restrictions
Soil composition
Products – how to reduce costs.

Anchoring | Foundation differences
Products – how to reduce costs.
SUNSTALLing the Future
Anchoring | Foundation differences
Geotech analysis done?
Ram and pull out test done?
Can the manufacturer offer solutions for different
anchoring systems?
Mixed deployment on one site.
Plan B!
Products – how to reduce costs.

Module Integration | Compact systems
Integrated systems are necessary to reduce costs
Modules should be part of the racking already
We need Ikea solutions & no loose hardware
Less manual work -> decreased costs
Higher quality
Products – how to reduce costs.
SUNSTALLing the Future
Al vs. Steel
Do you care?
Trend to steel
How about Bamboo?
At the end of the day the TCO will decide the game!
Products – how to reduce costs.

Automated Assembly
Is it going to be cost competitive?
Is the technology reliable?
Do we have enough big projects?
Deploy ability?
Equipment – how to reduce costs.

Logistics
High due date reliability.
Short delivery times -> JIT.
Low inventory level on site.
High capacity utilization.
Communication between manufacturer and Installer is
key!
Integration – how to reduce costs.

Construction
Does the customer knows what he wants?
Does the customer knows what he gets?
Who is coordinating the work on site?
Special resources & Tools necessary?
Plan B – are special procedures defined?
Integration – how to reduce costs.
