Turnkey solar power solutions

The right system depends on energy use, grid access and backup needs. Compare solar power solutions: grid-tied, hybrid and off-grid systems.

ONG Solar designs configurations for businesses and municipalities using site data. We assess power, battery capacity and project economics for each facility.

3 types: grid-tied, hybrid, off-grid
Backup: for critical loads
Selection: based on your site data
EPC: from design to commissioning

Grid-tied, hybrid and off-grid solar

Compare how the systems work and explore each solution. Municipal facilities have a dedicated section covering configurations for their specific needs.

For municipalities

SPP for municipal facilities

Solar generation for schools, hospitals and administrative buildings. We select the system type and backup configuration based on energy use and critical loads.

Based on energy use
Backup where required
Implementation support

Power

from 10 kW

Solar for municipal facilities

Off-grid solar power

Autonomous Solutions

A system designed to operate without the public grid. We size solar generation, storage and any additional power source for the load and seasonal conditions.

Operation without the grid
Energy reserve assessment
Additional source where needed

Power

from 100 kW

Off-grid solutions

Daytime self-consumption

Grid-Tied SPP

Solar generation for a grid-connected facility. A conventional grid-tied system without a separate backup arrangement does not power the site during a grid outage.

Daytime self-consumption
Works alongside the grid
No battery in the basic design

Hybrid Systems

Solar generation, batteries and the grid work together. Backup operation requires compatible equipment and a transfer arrangement; runtime depends on loads and stored energy.

Generation and storage
Backup designed for your loads
Generator where required

Power

from 50 kW

Hybrid solar systems

How to choose a solar power system

Start with the needs of your facility. Compare daytime energy use, grid availability and the required operating mode during outages.

A municipal facility sets the project requirements; it is not a separate electrical type of solar system.

Grid-tied

Main purpose: Offset part of daytime consumption with solar generation. During a grid outage: A basic grid-tied system stops; backup requires a separate arrangement.

Hybrid

Main purpose: Combine solar generation, the grid and battery storage. During a grid outage: Supplies the circuits included in the backup design, subject to suitable equipment and available energy.

Off-grid

Main purpose: Provide power without relying on the public grid. During a grid outage: Operation depends on generation, storage, loads and any additional source.
