Off-grid Solar System Working
Off-grid solar power system is often called a stand-alone solar system that operates independently of the electrical grid. It typically includes solar panels, a charge controller, batteries, and an inverter to provide power to a location that is not connected to the grid. ‘
Here’s a detailed explanation of how it works:
- Solar panels convert sunlight into direct current (DC) electricity.
- The charge controller regulates the voltage and current coming from the solar panels to the batteries, preventing overcharging and deep discharging.
- Batteries store the DC electricity generated by the solar panels for use when sunlight is not available, such as at night or on cloudy days.
- The inverter converts the stored DC electricity in the batteries into alternating current (AC) electricity, which is the type of electricity used by most household appliances.
Let’s understand this with example of a remote cabin with the following requirements:
- Daily Energy Consumption: 3 kWh (3 units)
- Solar Panels: 4 x 300W panels = 1200W total capacity
- Charge Controller: 40A MPPT charge controller
- Batteries: 4 x 12V 200Ah inverter batteries (connected in series for 48V system) = 9600 watt-hours storage capacity
- Inverter: 2kVA off-grid solar inverter
Daytime:
- The solar panels produce 1200W per hour under optimal conditions.
- Over 5 peak sunlight hours, they generate 6000 watt-hours (6 kWh).
- 3 kWh is used to power the cabin’s immediate needs.
- The remaining 3 kWh is stored in the batteries.
Nighttime:
- The cabin uses the stored 3 kWh from the batteries to meet its energy needs.
This off-grid setup ensures that the cabin has a reliable power supply without depending on the electrical grid. The system can be scaled up or down based on energy requirements and sunlight availability.
Difference Between Off-grid Solar System Vs On-grid Solar System
| Particulars | Off-grid | On-grid |
| Grid-dependency | Completely independent of the grid electricity | Connected to the grid |
| Cost | Higher upfront cost (includes batteries and additional equipment) | Lower upfront cost (no batteries needed) |
| Battery | Required to store energy for non-sunlight hours | Not required |
| Subsidy | Limited or no subsidies available | Often eligible for government subsidies |
| Warranty Period | 2-3 Years on Battery 2-5 Years on Inverter 25 Years on solar panels |
10 Years On-grid inverter warranty 25 Years on solar panels |
Frequently Asked Questions
Off-grid solar setup is ideal for:
- Areas with limited or no power supply
- Shops in remote areas
- Farms without grid connection
- Cabins or vacation homes located off the grid
The cost of an off grid solar system in India varies based on factors such as system size, type of batteries, and additional components like inverters and charge controllers. Usually, off-grid systems cost more than on-grid solar systems without batteries.
The size depends on your power consumption and the power ratings of your electrical appliances. Evaluate your daily power consumption in kilowatt-hours (kWh) to determine the system size. The more power you need, the larger (and more expensive) the system will be.
You will need a setup of 4 batteries to support a 5kW off-grid solar system.
Off-grid systems provide reliable power in areas with unpredictable power outages and ensure energy independence from the grid.
Unfortunately, there are no subsidies applicable on off-grid solar plant installation in India, However, you can get up to 40% ROI as solar subsidy with on grid rooftop solar systems.
