Solar kit components The lithium-ion photovoltaic self-consumption kit comprises the following products: 8 × Ulica Solar N-type TOPCon monofacial solar panels (505 W each): The 505 W Ulica Solar panel is a modern solution designed to maximize energy generation in confined spaces. Thanks to its N-type cell technology with TOPCon architecture, it improves conversion efficiency and low-light performance, delivering more energy throughout the day with a module efficiency of up to 22.07%. N-type architecture provides lower degradation and higher performance stability compared to traditional P-type modules. Its design optimizes thermal behavior, ensuring robust performance even in hot climates. Built with highly durable materials (silver aluminum frame and high-strength tempered glass), the module withstands up to 5400 Pa front-side load and 2400 Pa rear-side load. It incorporates MC4-compatible connectors and 1100 mm cables for easy installation. It carries a 15-year product warranty and a 30-year linear performance warranty, with low degradation: 1% in the first year and only 0.4% annually thereafter. Compact dimensions of 1952 × 1134 × 30 mm and weight of 23.5 kg facilitate handling and compatibility with standard mounting structures and optimizers. Tier 1 classification (BloombergNEF) for enhanced manufacturing reliability. 1. Deye Sun 5000 W hybrid inverter: The 5 kW Deye Sun hybrid inverter is a high-quality unit featuring a large LCD display for configuration and parameter monitoring. Highly configurable, it supports virtually any off-grid or self-consumption operation. It can be expanded without additional accessories by connecting further inverters in parallel, and features an IP65-rated waterproof design for enhanced durability. 10-year warranty. • BMS communication with leading lithium battery brands (e.g., WeCo, Pylontech) or voltage-based parameterization. • Automatic generator start: Enables command-triggered generator startup when battery charge is low. • New dual 500 V MPPT regulator supporting up to 8000 W: Allows series connection across two orientations thanks to its dual MPPT inputs, enabling up to 8000 W in a single solar system.
