Material warranty on the complete carport construction system with screw foundation and roof system made of photovoltaic panels - at least 20 years; 5. Warranty on inverters – at least 5 years; 6. Warranty on automation and control along with the application and other devices not listed in points 1–5 above – according to project documentation and Tauron Dystrybucja requirements – at least 24 months.
The Contracting Authority specifies that the above warranties may be given by the manufacturer or the Contractor.
The Contracting Authority requires service during the warranty period with a reaction time to start troubleshooting a failure or defect no longer than 36 hours from the moment of notification by the Contracting Authority. Notification of failure or defect must be possible 24 hours a day, 7 days a week (including Saturdays, Sundays, and holidays). Financial penalties are foreseen for delays in reaction time to start repairing failures or defects reported by the Contracting Authority.
Simultaneously, the Contracting Authority requires that the Contractor keeps "ready at hand" photovoltaic panels (minimum 10 pcs) available for replacement during the warranty period. The Contracting Authority also requires that the Contractor keeps "ready at hand" inverters (one type of each power class) available for replacement during the warranty period.
The Contracting Authority states that it holds: - The site development plan and building design for photovoltaic installation up to 5MW; - The site development plan and building design for photovoltaic installation up to 100kW; - Executive design; - Project Information Sheet.
The above technical documentation detailing the Contract Subject is included in Annex No. 1 to the Request for Proposal – Description of the Contract Subject and Technical Documentation.
The Contracting Authority indicates that: - The medium voltage cable line project remains to be developed by the Contractor within the Contract Subject; the Contracting Authority installed the medium voltage connection field; - The scope of construction of the access road to the transformer station is included in the Contract Subject. The road should be paved with paving stones, have curbs and drainage.
The Contracting Authority allows shutting down the plant for no longer than one day for the medium voltage line connection, as the connection field is already prepared.
The Contracting Authority points out that in case of necessity, the Contractor is responsible for extending the connection conditions. The Contracting Authority will provide necessary support in this respect. Concurrent investments may cause changes in connection conditions, but this does not affect the scope of the Contract Subject installation.

Evaluation criteria: - Criterion "Net price":
The Contracting Authority will assess the total net price for performing the Contract Subject.
The number of points assigned to each evaluated offer in the "Net price" criterion will be calculated according to the formula:
C = (CN / CO) x 40 - Criterion "Warranty on construction and installation works"
This criterion will be considered based on the warranty period length declared by the Contractor according to the formula:
G = ((Gb – 60) / 60) × 30
120 – maximum scored period - Criterion "Service – reaction time"
This criterion will be considered based on the reaction time declared by the Contractor in the Offer Form to start troubleshooting a failure or defect.
The maximum number of points achievable in this criterion is 10 points. - Criterion "Photovoltaic module efficiency (STC)"
This criterion will be evaluated according to the formula:
P = ((Pb − 21) / 2) × 20
The maximum number of points achievable in this criterion is 20.
