Location: Rooftop High-Power Solar Array
Source: Longlight Energy Published: 2026-07-09 Views: 311
Project Overview
High-power monocrystalline modules (400W / 450W / 550W) maximize energy density on limited roof real estate, then couple to Longlight-INV hybrids and ESS for complete energy systems.
Customer Challenge
Customers want higher kWh per square meter while keeping racking simple and inverter MPPT windows compatible.
Longlight Solution
Specify high-power panels from the product center, string them into dual-MPPT hybrid inverters, and add wall or cabinet storage based on backup goals.
System Architecture
- High-power PV modules on roof rails
- String combiners → hybrid inverter MPPT
- Optional ESS for time-shifting energy
- Monitoring of generation and self-use ratio
Key Products Deployed
Technical Highlights
