Construction of a photovoltaic power plant for the needs of "Ka Engineering" Ltd. with a capacity of 25 kW. The increase in energy and energy carriers has a lasting negative impact on our company. Price fluctuations create serious difficulties, both for sustainable development and for our operational activities. Our company has already implemented numerous measures to renovate the building stock to ensure maximum energy efficiency in our activities and processes at our plant. 100% of the lighting in production and auxiliary rooms has been replaced with energy-efficient lighting. We have also purchased and put into operation energy-efficient equipment for performing individual processes. Main characteristics of the facility planned for construction: Power – 25 kW Technical criteria Photovoltaic modules Module efficiency ≥ 20% Product warranty ≥ 12 years First-year degradation ≤ 3% Linear degradation for single-faced modules ≤ 0.6% per year, guaranteed for ≥ 25 years Inverters for the photovoltaic module Inverter efficiency (European weighted efficiency) ≥ 96% Harmonic distortion (THD) ≤ 5% Input voltage from PV strings: ≤ 1500 VDC Product warranty ≥ 10 years Possibility to store and provide information on energy produced by the photovoltaic system; Availability of a device that limits the feed-in of electricity into the grid compatible with the inverter or a built-in function of the inverter Inverters for storage system Product warranty ≥ 10 years Batteries Operating ambient temperature: 0-45°C Product warranty ≥ 5 years Performance warranty: ≥ 10 years Metal mounting structures for the panels are planned to be located on the 'Finished Product' warehouse, which has an area of approximately 450 sq.m. and a roof structure with a southern exposure. Pre-reinforced with metal frames.
