Solar Energy Systems
TURENO provides solar energy solutions suited to each business's energy demand, consumption profile and site conditions.
It offers engineering and implementation services for a range of needs, from feasibility studies and design for solar PV investments to turnkey installations, and from energy storage solutions to the performance assessment and improvement of existing systems.
Solar PV Feasibility and Design
For solar PV investments to be planned soundly in technical and economic terms, the facility's energy consumption, the conditions of the installation area and the generation potential are assessed together.
On the basis of the data obtained, TURENO prepares the feasibility study on which the investment decision is based, and provides the design services required for the solution found suitable.
Scope of Services
- Review of the facility's energy consumption and consumption profile
- Assessment of the technical conditions of the installation area
- Analysis of the solar energy generation potential
- Determination of the appropriate system capacity and configuration
- Calculation of expected energy generation and the self-consumption ratio
- Assessment of the projected investment cost and economic return
- Design work required for the system found suitable
Turnkey Solar PV Installations
TURENO delivers solar energy investments on a turnkey basis, from feasibility and design to equipment procurement, and from on-site installation to testing and commissioning. The system design is developed in line with the facility's energy demand, consumption profile, site conditions and operational requirements. Depending on the needs of the project, technical feasibility and the requirements of the applicable legislation, grid-connected, off-grid or hybrid system solutions can be implemented.
System Solutions
On-Grid (Grid-Connected) Solar Energy Systems
These are solar energy systems that operate connected to the electricity grid. The electricity generated by the solar panels is used to meet the facility's consumption. When generation does not cover the facility's consumption, the energy required is drawn from the grid. When generation exceeds consumption, the surplus energy can be exported to the grid, depending on the system's connection arrangement.
On-grid solar PV projects are commissioned once the grid connection application, technical evaluation, design, approval and acceptance procedures have been completed in accordance with the applicable legislation. Because standard on-grid systems operate in synchronization with the grid, they stop generating during a grid outage for safety reasons.
Off-Grid (Stand-Alone) Solar Energy Systems
These are systems designed to meet energy demand without a connection to the electricity grid. Solar generation and energy storage capacity are sized according to the facility's load profile, daily energy demand and the targeted continuity of operation.
Where required, auxiliary energy sources can be incorporated into the system to support continuity of supply.
Hybrid Solar Energy Systems
These are solutions in which solar generation operates together with an energy storage system and the electricity grid. The energy generated by the solar panels is used first to meet the facility's consumption. When generation exceeds consumption, the surplus energy can be stored in batteries.
During periods when there is no solar generation, or when it is insufficient, the facility's consumption can be met from the stored energy. When battery capacity is insufficient, the grid steps in and contributes to continuity of supply.
With a suitable inverter, energy storage, protection and control infrastructure, the system can be designed to continue supplying designated loads during grid outages.
Turnkey Project Scope
- Determination of the system architecture and installed capacity suited to the facility
- Selection of panels, inverters, mounting structures and other main equipment against technical criteria
- Preparation of electrical and mechanical detailed designs
- Design of DC and AC cabling, protection, earthing and connection infrastructure
- Supply of equipment and materials suited to the project
- Electrical and mechanical site works
- Technical coordination and quality control of the installation process
- Electrical checks, functional tests and commissioning
- Handover of the system ready for operation and in working order
Solar-Integrated Energy Storage Solutions
Where solar generation and the facility's consumption occur at different times, energy storage systems allow the energy generated to be used more effectively and support continuity of supply. TURENO designs and implements energy storage solutions to be integrated with existing or planned solar energy systems, in line with the facility's consumption profile, the solar generation characteristics, power demand and usage scenarios.
Objectives
- Using a higher proportion of solar-generated electricity within the facility
- Managing the gap between when energy is generated and when it is needed
- Supporting continuity of supply to designated loads during grid outages
- Developing solutions to manage sudden and high power demands
Scope of Services
- Analysis of the facility's consumption data and solar generation data
- Definition of the usage scenario for the storage system
- Sizing of the required power and energy capacity
- Selection of suitable battery technology and system components
- Development of the system architecture, power conversion and control infrastructure
- System integration with the solar PV system and the facility's electrical infrastructure
- Definition of protection and operating scenarios
- Installation, testing and commissioning
Analysis and Improvement of Existing Solar PV Systems
The generation performance, system data and site conditions of a business's existing solar energy systems are assessed together to analyze their current operating condition. TURENO carries out analyses to identify the differences between expected and actual generation and the technical factors affecting performance. On the basis of the findings, technical recommendations are developed to improve system performance.
Scope of Services
- Review of historical generation data and monitoring system records
- Comparison of actual generation with system capacity and expected generation values
- Assessment of performance differences at inverter and panel-group level
- Review of the effects of shading, site conditions and system layout on generation
- Assessment of electrical losses and the operating conditions of system components
- Analysis of fault, alarm and operating records
- Site surveys and technical measurements where necessary
- Identification of the root causes of performance losses
- Development of technical improvement options and actionable measures
