Design of solar power plants

Engineering design of solar power plants, featuring energy efficiency calculations, financial modeling, and comprehensive lifecycle analysis.

A project that pays back the investment

We design solar power plants for industrial enterprises, developers, and infrastructure facilities. Each solar power plant project is a thorough engineering calculation that accounts for site insolation, the facility's energy consumption profile, and grid operator requirements.

Technological Expertise

When selecting equipment, our engineers rely on advanced heterojunction technology (HJT) due to its higher efficiency, minimal temperature coefficient, low degradation rate, and maximum performance under low insolation and diffused light conditions. This directly increases the annual power generation of the solar power plant (SPP).

Investment Accuracy

SPP design begins with modeling the prospective facility and calculating performance metrics using a physical-mathematical model. This includes electricity generation forecasting based on international standards and financial institution requirements. We calculate key financial metrics: Levelized Cost of Electricity (LCOE), Net Present Value (NPV), and Internal Rate of Return (IRR) of the solar power plant project. This allows investors to evaluate actual project economics prior to the EPC/construction stage and eliminate risks associated with inaccurate generation forecasts.

Custom Engineering Approach

Every project is tailored to the Customer's specific goals (e.g., the facility's load profile and/or site characteristics). We design the optimal system architecture, placement layout, mounting structure type (fixed-tilt or solar trackers), evaluating wind and snow loads on structural supports, and model the electrical operating modes and energy parameters of the future solar plant. There are no standardized SPP projects—only engineered, site-specific solutions.

Grid Reliability and Integration

Engineering documentation includes the design of protection systems, automation, and parallel operation of the SPP with the local grid infrastructure (including export control systems where required). This ensures stable, efficient operation and guarantees equipment safety.

Feasibility Stage Risk Management

Designing grid-tied, off-grid, and hybrid SPPs allows technical constraints and risks to be identified at the pre-project stage through grid connection terms analysis, connection point audits, and land plot assessments. We eliminate these uncertainties prior to project execution, protecting the Customer's budget.

Scalability and Modernization

A well-engineered solar plant design accounts for future business expansion. We incorporate a modular architecture and sufficient reserve capacity within key cabling and grid infrastructure. This enables cost-effective capacity expansion in the future.

Designing plants of different types

Grid-Tied Solar Power Plants

Designed to operate in parallel with the external power grid without energy storage systems. Generated electricity offsets on-site consumption, reducing grid energy costs. Any excess power is fed into the grid or limited by an active power control system if required by the Grid Connection Terms.

Engineering Challenge: Analyze the facility's hourly load profile, select the optimal grid inverter configuration, and determine the exact SPP capacity needed to maximize self-consumption. Ideal for facilities with high daytime demand, ranging from commercial centers to large industrial enterprises.

Hybrid Solar Power Plants

Designed for grid-connected facilities facing unreliable power supply or capacity constraints. These systems combine grid-tied and off-grid functionalities: they operate in parallel with the grid while featuring an Energy Storage System (ESS) for backup power and load management.

Engineering Challenge: Optimize energy flow control algorithms. The solar plant design includes automatic backup algorithms for critical loads during grid outages, active peak shaving under utility restrictions, and maximum offset of grid power consumption. Ideal for continuous-process industries where power interruptions are critical.

Off-Grid Solar Power Plants

Designed for remote sites lacking centralized power grid access. Operating as standalone hybrid power systems, they deliver reliable off-grid power by integrating renewable energy sources (PV modules, wind turbines), energy storage systems (ESS), and backup generation (diesel or gas gensets).

Engineering Challenge: Calculate daily and seasonal load profiles for precise battery capacity and genset power sizing. The primary design objective is to ensure reliable off-grid power or maximize the fuel displacement ratio (diesel fuel savings) while maintaining required power reliability. For remote industrial sites and field camps, solar power plants can be supplied as mobile containerized solutions.

Station Connection Options

Industries of Application

We engineer SPP projects tailored to the operational requirements of industrial, mining, and commercial enterprises. We integrate solar generation into existing infrastructure or build off-grid energy systems from scratch for remote sites lacking grid access and temporary facilities at early development stages.

How the design process works

Requirement Definition and Goal Alignment

We collect and analyze site parameters: climatic conditions, regional insolation, site specifics, and the facility's electrical load profile. We also review grid connection technical conditions.

Feasibility Study and Financial Modeling

By modeling various SPP configurations and operational scenarios, we determine optimal plant parameters, evaluate CAPEX/OPEX, and calculate LCOE, IRR, and payback periods within the feasibility study.

Comprehensive Engineering Surveys

We perform geotechnical, geological, and hydrometeorological site surveys to evaluate terrain and soil conditions, which are critical for site layout design and foundation/mounting system selection.

Basic Engineering Solutions (BES) and Equipment Selection

We develop BES and select key equipment tailored to project requirements: PV module technology (including high-efficiency HJT modules), inverters, mounting structures (fixed-tilt or solar tracking systems), switchgear, and auxiliary monitoring and communication equipment.

Detailed Engineering Documentation

We prepare primary design documentation in strict compliance with applicable regulatory standards. This stage includes site plans, single-line and schematic diagrams, cable selection, and protection/automation calculations for grid compatibility.

Permitting and Regulatory Approvals

We assist throughout regulatory reviews, coordinating technical decisions with grid operators and facilitating state or third-party expert reviews of the design documentation.

Working Documentation

Following regulatory approval, we finalize detailed working documentation, cable schedules, and precise equipment/material specifications required for construction and installation works (EPC).

Construction Supervision

Our engineers oversee construction quality, providing technical supervision during installation, site assembly, and commissioning to ensure building alignment with approved design documentation.
