Renewable Energy Systems Designer
Renewable Energy Systems Design sits at the most commercially exciting part of the clean energy boom. You are designing the systems that businesses and homeowners will use to generate and store their own electricity for the next 25 years. In Sri Lanka, the timing is exceptional — the market is growing rapidly, experienced designers are scarce, and the combination of high freelance potential and international remote work opportunity makes this one of the most attractive engineering career paths available right now.”
About This Role
Designs solar PV, wind, and hybrid energy systems for domestic and industrial applications.
A Day in the Life
Design integrated renewable energy systems — combining solar PV, battery storage, grid connection, and energy management — to create optimised energy solutions for commercial, industrial, and utility clients.
- Design hybrid energy systems — solar + battery + grid or solar + diesel + battery (off-grid)
- Optimise system sizing using simulation tools — minimise LCOE (Levelised Cost of Energy)
- Design battery energy storage systems (BESS) — sizing, chemistry selection, BMS specification
- Prepare detailed system designs — single-line diagrams, cable sizing, inverter specifications
- Simulate load profiles and energy balance for client energy consumption patterns
- Design monitoring and energy management systems (SCADA/EMS for renewable assets)
- Specify and support procurement of renewable energy equipment
- Prepare technical documentation for client handover and O&M teams
Work Environment
Office-based technical design role with periodic site visits for commissioning and monitoring. Renewable Energy Systems Designers often work for EPC companies, energy consulting firms, or equipment suppliers. The battery storage sector is growing rapidly alongside solar — BESS design is a high-value emerging specialisation within Sri Lanka's energy sector.
Typical hours: 45h/week · WLB score 7/10 · OCCASIONAL overtime
Office-based design work with good balance outside project commissioning phases. Good flexibility in many renewable energy companies.
