01
Assessment & consulting
We assess the site, loads, grid connection options, operating modes and technical constraints.
About us
Engineering thinking behind every working solution.
Power Design Engineering is an electrical engineering company specializing in photovoltaic power plants, energy storage systems and LV/MV electrical infrastructure.
Who we are
From technical assessment to reliable operation.
Our team develops and delivers end-to-end engineering solutions for energy generation, storage, distribution and intelligent energy management.
We work across industrial, commercial, public and residential projects. Every solution is shaped around real loads, site conditions, investment objectives and the applicable technical and regulatory requirements.
We do not simply supply equipment. We engineer a system in which every component has a clear purpose, the correct protection and a measurable result.

Frequently asked questions
Clear answers before the project begins.
How do you determine the required PV capacity?
We analyse consumption, load profiles, available area, grid connection and the target operating mode. Capacity is selected for a sound technical and economic result, not merely to fill the available space.
When does battery storage make sense?
When the project requires higher self-consumption, peak-power reduction, backup supply, Zero Export or island operation. Energy capacity and power are sized against the actual load.
What does Zero Export mean?
The system measures energy flow at the grid connection point and controls the inverters so that export does not exceed the configured limit.
Can the system operate during a grid outage?
Yes, when the inverter, battery, protection and electrical architecture are designed for backup or island operation. This is defined at the technical-design stage.
What are the main project stages?
Site assessment, analysis and sizing, project documentation, supply, construction, testing, configuration, commissioning, monitoring and maintenance.
Do you work on existing systems?
Yes. We provide diagnostics, retrofits, ESS integration, inverter replacement, protection corrections, communications, control and monitoring upgrades.
