Tenders Are Invited For Installation Of Photovoltaic Installations And Delivery Of Pv Panels Along With Construction And Installation Works, As Part Of The Project Słoneczny Mikołowski - Construction Of Photovoltaic Installations

1.3.1. Task No. 1: Installation Of A Photovoltaic Installation With A Capacity Of 35.88 Kwp Located On The Roof Of The Building Of The Secondary School No. 2 In Mikołów At Ul. Pokoju 4. A. The Subject Of The Order Is The Delivery And Installation Of A Photovoltaic Installation With A Capacity Of 35.88 Kwp. On The Roof Of The Building Of The Secondary School No. 2 In Mikołów At Ul. Pokoju 4. The Works Will Involve The Installation Of 78 Monocrystalline Modules On The System Support Structure And The Remaining Dc And Ac Electrical Infrastructure. The Designed Installation Will Be Aimed At Generating Electricity. The Installation Will Consist Of Photovoltaic Panels Divided Into So-Called Chains. Thong. Photovoltaic Panels That Will Work With The So-Called Inverter. Inverter - A Converter That Changes Direct Current (Dc) Into Alternating Current (Ac). After Changing The Nature Of Electricity, It Will Be Used For The Buildings Own Needs And The Remaining Part, The So-Called Excess Production Will Be Resold To The Distribution Network Operator. The Installations Own Needs Will Be Covered First Of All By Self-Consumption Of Electricity Produced In The Subject Installation; At Night, The Electricity Necessary For The Inverters Own Needs Will Be Taken From The Local Grid To Which It Will Be Connected. Scope Of Assembly Works: • Installation Of The System Supporting Structure On The Roof Building (Ballast); Installation Of A Photovoltaic Installation With A Capacity Of 35.88 Kwp.
