Brief on Z-One Holding
Z-ONE Holding provides Integrated Value-Chain Solutions in the field of PV SOLAR ENERGY.
Z-One ‘s objective is to conserve its unique position of servicing the complete value chain related to PhotoVoltaics (PV) through relationships and partnerships strictly with international market leaders of the PV industry.
As such therefore, not only do we get involved with existing and available opportunities, but we also have to face and handle the relevant challenges on several fronts: Political, Regulatory, Financial and equally importantly, Technical.
We operate and cover the whole MEA Region from our headquarters in Dubai - UAE, as well as from other operational subsidiaries in Egypt, Morocco, and Turkey.

Basis for Growth Potential
• Today, solar energy is less than 0.1 % of global energy• The “sunny” parts of the world are ready for photovoltaic• Cost reduction of cells and modules will drive photovoltaic• Photovoltaic will be one of the most economic energy sources with a large
market potential

Opportunities in MEA Region

• High Irradiation• Available Land• Power Shortages• Very low electricity penetration rate• Huge off-grid market• High appetite for international financing institutions to the African market
And in the Gulf some differences are:• The high potential growth in electricity consumption, and• The cheap(er) financing due to political stability
Opportunities in MEA Region

Already stated above……challenges on several fronts: Political, Regulatory, Financial, and equally importantly,
Technical.
Challenges in MEA Region
![Page 10: Opportunities and challenges for PV utility scale projects (MEA Region)](https://reader035.fdocuments.us/reader035/viewer/2022062501/56816360550346895dd42d5f/html5/thumbnails/10.jpg)
• Regulatory Framework: Lack of Availability of FIT/PPA regulation:
Countries having already an established regulation: Jordan, Kenya, Rwanda, South Africa & Uganda ONLY
• Region Stability
CHALLENGESPOLITICAL/REGULATORY
![Page 11: Opportunities and challenges for PV utility scale projects (MEA Region)](https://reader035.fdocuments.us/reader035/viewer/2022062501/56816360550346895dd42d5f/html5/thumbnails/11.jpg)
• Local banks for example are not familiar with PV sector - high interest rate for debt financing due to political instability (1 to 100M $ projects)
• We can also argue that as developers “Only thing holding cleantech back is the financing,” financiers respond that there’s a lack of supply and the market is not scalable enough for a feasible business case, too high barriers of entry, not enough economies of scale, no sufficient standards have been developed…

CHALLENGESTECHNICAL
Are deserts the right place for PV modules, Inverters…etc?
Benefits:Large and low cost areaHigh annual irradiance
Problems:High temperature
Sand stormsEfficiency
( for modules at least, we already have “desert qualified” standards)

CHALLENGESDEGRADATION EFFECTS
1 Degradation:The abrasive effect produced by sand moved by wind is a negative effect
2 Other typical problems:a) High temperature decrease efficiency due to negative thermal coefficientb) High irradiance produce strong hot-spot effects (and subsequent ones)c) High temperature may decrease the adhesion of the layers of modules
3 Other problems:d) Wind (standard test up to 130 km/h)e) Flying stones: comparable to hailf) Dune movementg) Inadequate O&M (cleaning)h) Structural Strength of Mounting Systems

CHALLENGESHIGH TEMPERATURE EFFECTS
We analyzed the effect of a long exposure to high temperature. In particular some results of adhesion between encapsulant and backsheet/glass are compared after 3 consecutive periods of 1000 hours exposure to 85°C. (These parameters have a key role on the quality of the lamination process and materials).
We can see in the next graph the strong degradation effect on adhesion due to the above described test conditions (peel test)
The «Peel» test consists in pulling the backsheet with growing force to determine the minimum necessary value ( in N) to delaminate (disconnect ) the different layers.

CHALLENGESHIGH TEMPERATURE EFFECTS
HOT SPOT EFFECT: Low quality modules/backsheet are almost always damaged
![Page 19: Opportunities and challenges for PV utility scale projects (MEA Region)](https://reader035.fdocuments.us/reader035/viewer/2022062501/56816360550346895dd42d5f/html5/thumbnails/19.jpg)
CHALLENGESHIGH TEMPERATURE EFFECTS
Mechanical stress produced by hot spot can crash cells, if the cells are too thin or badly laminated
