Tenders Are Invited For Replacement Of Heat Sources At The Primary School In Rogów Along With The Installation Of Photovoltaic Panels.

The Investment In Question Involves The Modernization Of The Boiler Room Installation, Consisting In The Construction And Installation Of A 300 Kw Class 5 Solid Fuel Pellet Boiler, Along With A Pneumatic Pellet Loading System And A Fuel Storage System. The Designed Solution Provides For The Dismantling Of The Existing Coal-Fired Boilers Along With Accompanying Installations In The Boiler Room And Fuel Warehouse. It Is Planned To Install A New Pellet Boiler With A Pneumatic Fuel Feeder With A Blade Reel Supplying Fuel From The Fuel Warehouse. It Is Also Planned To Install Dn100 Pellet Loading Stubs That Will Enable Fuel To Be Loaded Into The Warehouse. In Addition, The Installation Of Installations And Accompanying Devices Inside The Boiler Room Is Planned, Which Includes: A Buffer, A Domestic Hot Water Tank, Central Heating Distributors, Pumps, Fittings, Etc. In Accordance With The Descriptive And Drawing Parts Of The Project. As Part Of The Task: Replacement Of The Heat Source In The Primary School In Rogów Along With The Installation Of Photovoltaic Panels, It Is Planned To Install A Photovoltaic Installation With A Capacity Of 39.5 Kw On The Roof Of The Primary School Building, In Accordance With The Attached Roof Projection. Based On The Analysis Carried Out To Assess The Technical Feasibility Of Installing A Photovoltaic Installation For The Primary School Building And On The Basis Of Materials Provided By The Manufacturers Of The Solid Fuel Pellet Boiler, Data On The Plot And The Constantly Increasing Demand For Electricity, It Was Possible To Install A Photovoltaic Installation Consisting Of 60 Photovoltaic (Pv) Modules On The Roof Of The School Building. The Rated Power Of The Installation With This Number Of Pv Modules Will Be 39.5 Kwp. The Designed Photovoltaic Installation Should Be Connected To The Buildings Internal Electrical Installation. The Energy Produced Will Be Used For The School Complexs Own Needs. In The Event Of A Power Outage In The Grid, The Inverter Goes Into Sleep Mode, Waiting For The Grid Voltage To Return, Which Prevents The Installation From Islanding. The Photovoltaic Installation In Question Will Consist Of The Following Elements:• 60 Pcs. Photovoltaic Modules Made Using Perc Polycrystalline Technology With A Nominal Power Of 500 Wp Each;• 1 Pc. Three-Phase, Transformerless Inverter With Ac Power Up To And Including 40 Kw - For Photovoltaic Modules Converting Direct Current Energy Into Alternating Current Energy With Parameters Adapted To The Grid To Which The Inverter Transfers The Excess Energy Produced. The Inverter Will Be Mounted Outside On A Supporting Structure Intended For Pv Modules; • Single-Support Structure Of The Mounting System For Photovoltaic Modules Placed On The Roof Surface. The Pv Modules Will Be Mounted According To Its Inclination At An Angle Of 35°, With A South Azimuth Of 32°. The Installation Azimuth Results From The Parallel Foundation Of The Structure In Relation To The Plot Boundary; •
