The item of the order is divided into two parts. Part 1 - Design, delivery and installation of solar installations and Part 2 - Design, delivery and installation of solar installations

Part 1: Design, delivery and installation of photovoltaic installations, including:

1. Conduct a technical audit (local vision) for each location,

2. Execution of design documentation for each location,

3. Appropriate design and calculation of the cross-section of the stacked wires (the calculations are included in the design and post-construction documentation); design the use of UV-resistant wires in sunlit areas,

4. Conduct the required consultations, obtaining the required confinement and permits (including fire protection arrangements),

5. Applying to the installation directions of the devices contained in the documentation,

6. Installation of photovoltaic panels with fixtures,

7. Installation of photovoltaic panels, including:

• angle of inclination of photovoltaic panels — use optimal tilt angle, invariant for panel exposure throughout the year,

• azimuth angle of photovoltaic panels — an optimal azimuth angle should be applied to the southern direction, with possible deviation, guaranteeing the required efficiency and effective operation of photovoltaic installations on a full year scale,

• PV shading — in order to avoid unnecessary shading effects, the location of photovoltaic panels at the assembly stage should be analysed so that the devices are positioned far from obstacles and elements that potentially, in the future, may be an element shading (e.g. growing trees),

8. Supplement of cavities of walls, ceilings and floors, repair of plaster, facades and its warming, sealing of roofing material after passages of wires,

9. Possible modifications to the assumptions only in agreement with the investor, if this will lead to better use of the technical capabilities provided by the equipment planned for assembly,

10. Make possible modifications, configuration of the designed wiring so as to make optimal use of the technical capabilities of the equipment planned for assembly,

11. Any derogation from the documentation will be agreed with the investor's representative,

12. Any problems should be signalled to the investor representative and, after their resolution, documented by modifications to the copy of the post-built documentation,

13. User training,

14. Preparation or submission of the instructions for use,

15. Transfer of warranty cards,

16. Preparation, obtaining user signatures and submission of complete application documents of micro-photovoltaic microinstallation (Notification/Installation document of microinstallation connection to ENERGA-OPERATOR S.A., when the installed power of the microinstallation is not known more than the existing interval power for this energy attachment point),

17. Monitoring the status of the submitted application at least until the microinstallation is connected to the electricity grid (if necessary, the development of amendments for submitted application documents),

18. Preparation of post-construction documentation.

Part 2: Design, delivery and installation of solar installations, including:

1. Conduct a technical audit (local vision) for each location,

2. Execution of the design documentation for each location and obtaining the required arrangements, consignments and permits,

3. Installation of solar collectors with fittings,

4. Launch of the installation,

5. Retraining users,

6. Preparation of the instructions for use and transmit it to users,

7. Supplement of cavities of walls, ceilings, sealing of roofing material after passages of wires,

8. Exercise of post-built documentation.
