Solar System Comparison Matrix
Understand the core differences between Off-grid, On-grid, and Hybrid solar plants to make an educated purchase.
| Key Features & Comparison | On-Grid System (Grid-Tied) | Off-Grid System (Stand-Alone) | Smart Hybrid System |
|---|---|---|---|
| System Cost (BDT) | Lowest (No battery required) | Medium-High (Large battery needed) | Highest (Flexible battery + dual inverters) |
| Battery Required? | No | Yes (Mandatory) | Yes (Highly Recommended / Flexible) |
| Power During Grid Outage? | No (Shuts down for utility line worker safety) | Yes (Completely independent) | Yes (Instantly switch to critical loads) |
| Utility Bill Savings | Highest (Net metering exports all daytime excess) | Medium (Bill is zero, but high initial battery cost) | Extremely High (Intelligent combination of export and self-use) |
| Net Metering Supported? | Yes (Full compatibility with DESCO, DPDC, etc.) | No (Isolated from grid) | Yes (Can export excess when batteries are full) |
| System Maintenance | Lowest (Only panel washing) | High (Battery replacements every 5-10 years) | Medium (Lithium batteries require zero daily maintenance) |
| Best Suited For | Grid-connected homes and heavy-load daytime factories | Rural islands, remote telecom towers, isolated resorts | Residential areas with high load-shedding and high utility tariffs |
Garments & Heavy Industry
We strongly recommend **On-Grid Systems** with Net-Metering for factories. Since factories run heavy industrial loads during daytime sun hours, they consume and save all generation directly with no heavy battery cost.
Residential & Offices
We recommend **Smart Hybrid Systems** for residential areas experiencing frequent load-sheddings. They keep ACs, lights, refrigerators, and water pumps active while saving daytime bills using Net-Metering.
Remote Islands & Farms
We recommend **Off-Grid Systems** for rural locations (Chads, remote agricultural fields, telecom towers). They offer complete self-sufficient electricity far from utility grids.
