What we do

Solar PV and batteries — from first idea to a working system.

Power Design Engineering designs, supplies, installs and maintains solar PV systems and batteries for homes and businesses in Kardzhali, Momchilgrad and the region. We assist with the grid connection, commission the system and monitor it afterwards, and where needed we also build the cable lines and substations that serve the site.

Brands & technologies

Equipment selected for the actual task.

We work with the Huawei FusionSolar, Deye and Sungrow platforms for inverters, batteries and monitoring, panels from Suntech, JA Solar and JinkoSolar, and electrical equipment and meters from ABB, Schrack Technik, Eastron and Janitza. The brand and model are chosen for the task and the site.

Our approach

One responsibility. Four clear stages to a working PV plant.

Every project goes through four stages: site analysis, engineering, construction, and commissioning with maintenance. We take them on in sequence as one contractor, so the system is safe, measurable and ready for real-world operation.

01

Analysis

Site, load profiles, objectives and constraints.

02

Engineering

Sizing, technical solution and documentation.

03

Construction

Supply, installation, connection and testing.

04

Commissioning & support

Configuration, monitoring and technical service.

Why choose us

One engineering partner. End-to-end responsibility.

One team is responsible for the design, the equipment, the installation and how the system runs after commissioning. We size from the site's real loads, follow the applicable technical requirements and stay involved with monitoring and maintenance.

End-to-end engineering

From technical assessment and system studies to construction, configuration and commissioning.

Site-specific sizing

Power, capacity and operating modes are selected around real loads, site conditions and client objectives.

Regulatory compliance

We incorporate applicable technical requirements, protection, selectivity and the required project documentation.

Monitoring and support

Our involvement continues after commissioning with supervision, diagnostics, optimization and technical service.

Solar PV and battery energy storage system

Integrated control

Solar PV and battery storage designed to work as one.

When the PV system, the battery, the metering and the control are engineered together, more of the power produced is used on site, and the system can limit what it feeds into the grid and supply selected loads during an outage. These modes are set in the design.

  • ✓High self-consumption
  • ✓Zero Export and power control
  • ✓Backup and island operation
  • ✓Centralized monitoring
