Solar system comparison
Compare on-grid, off-grid and hybrid solar system architectures by grid dependence, battery requirements, backup capability and project application.
Answer first
Choose on-grid when a stable utility connection is available and bill reduction is the main objective. Choose off-grid when the site must operate independently. Choose hybrid when solar, batteries, grid or generator must work together for self-consumption and backup.
Side-by-side comparison
Use this table for initial screening, then confirm the current model, certification and system design before ordering.
Lower system complexity, high solar utilization and straightforward grid export or self-consumption
Normally stops during a grid outage unless backup equipment is included
Operates without the utility grid and can integrate battery storage and generators
Requires careful load, surge, battery-duration and solar-resource sizing
Coordinates PV, batteries, grid and optional generator through one control architecture
Battery compatibility, operating modes and local grid rules must be confirmed
Decision criteria
Confirm grid availability, outage frequency, export rules and whether uninterrupted operation is required.
Use daily energy, peak power, surge loads and critical-load priorities to select inverter and storage capacity.
Compare energy savings, backup value, generator fuel reduction, battery replacement and installation complexity.
Frequently asked questions
A standard on-grid inverter normally shuts down during an outage. Backup requires a compatible hybrid inverter, battery or dedicated backup interface.
Storage duration depends on the critical load, solar resource, weather autonomy and generator strategy. It must be calculated from the site load profile.
Yes. SolarXport can coordinate modules, hybrid inverter, compatible batteries, protection and technical documentation around the project requirements.
