01The challenge
Odra's CNC lines, compressors and heat-treatment furnaces draw a steady 1.4 MW from 06:00 to 22:00, and the furnaces add peaks on top. Energy had become the plant's second largest cost after people, and the finance team wanted a fixed price and a payback it could check.
02What we built
The plant's five sawtooth bays face south, which suits panels well. We used every bay, kept walkways for roof maintenance and added a 1.5 MWh battery that catches the furnace peaks. The system was bought outright on a fixed price, with the yield model attached to the contract.
03The result
The array makes 3,100 MWh a year and the plant uses 88% of it. Monthly reports from our Wrocław team compare the real yield against the contract model, line by line.
How the project ran
Assessment
January 2024
Meter data, furnace schedules and a structural review of the sawtooth trusses.
Design and contract
February to April 2024
Bay-by-bay layout, peak-shaving controls and a fixed-price contract with the yield model attached.
Installation
May to October 2024
One bay at a time over the production floor, with nets and night work over the furnaces.
Monitoring
From November 2024
Monthly yield reports against the contract model, prepared in Wrocław.
We bought on a fixed price and a payback we could check. The monitoring report and our energy bill tell the same story.
Site assessment
A site like Odra Precision Components's? Let us look at yours.
An engineer reviews your meter data and roof, visits the site and sends a written proposal with a design, a yield model and the financing options that fit. It costs nothing and commits you to nothing.
