As the world turns to cleaner energy, solar power is becoming a top choice for homes and businesses in Bangladesh. When considering solar installation, many customers are confused between on-grid and off-grid solar systems. Understanding the differences can help you make the right investment—and Solar Tech Bangladesh is your most trusted partner in this journey.
What is an On-Grid Solar System?
An on-grid solar system, also known as a grid-tied system, is connected to the national electricity grid. It generates power from the sun during the day and sends excess electricity back to the grid. When solar power is unavailable (e.g., at night), the system draws electricity from the grid.
Key Features:
-
Works only when the grid is active.
-
Excess energy can be sold back through net metering.
-
No batteries required, which reduces upfront cost.
Best For:
Urban areas with reliable grid access and customers looking to reduce electricity bills.
What is an Off-Grid Solar System?
An off-grid solar system operates independently of the national grid. It uses solar panels to generate electricity and stores energy in batteries for use during nighttime or cloudy days.
Key Features:
-
Not dependent on the electricity grid.
-
Requires battery storage for backup.
-
Higher initial investment due to battery cost.
Best For:
Remote locations without grid access or areas with frequent load shedding.
Major Differences at a Glance
| Feature | On-Grid System | Off-Grid System |

| Battery Usage | Not Needed | Essential |
| Cost | Lower (no batteries) | Higher (due to batteries) |

| Net Metering | Available | Not available |
Which One Should You Choose?
-
Choose On-Grid if you want to save money on your electricity bill and live in an area with a reliable power supply.
-
Choose Off-Grid if you’re in a rural area or want full independence from the electricity grid.
