You must be confused between On-Grid Solar Power Kit and Off-Grid Solar power kit, and what would be the right choice for you. But let me ask you, Do you know actually know what is an On-Grid System or Off-Grid System? If your answer is yes, then I think you might already know which kind of system you need to opt. And, if your answer NO, then this is the time you need to know what is an On-Grid and Off-Grid Solar Energy system before getting one. So why wait, let me explain you about those in detail.
On-Grid Solar Energy System
To start with, an On-Grid Solar energy system doesn't have any battery and hence there will be no back-up power. The power that is generated via Solar Panels will be sent to Inverter. Here, the On-Grid Inverter converters DC power to AC Solar. The output AC power line of the inverter will be connected to the mains, i.e., in between main switch and the Net Meter (For more details about Net Meter, Click here). Since, the On-grid Solar Inverter output is connected to Mains, all the appliances such as AC's, Motor's, Refrigerators, TV's, Fans, Lights and what not, every appliances can consume the power generated by Solar panels.
Whatever the appliances that are turned on, first they will consume the power coming from Solar Inverter. If the power coming from Solar is not sufficient, then only they will draw power from Government power supply (Grid). And if the power generated from Solar is more than the power consumed by appliances, then in that case, the remaining power that is generated will be sent to Government Grid via Net meter.
By the end of the month, the whole solar rooftop power that you generated and sent to Government grid, and the power that took from Government grid will be calculated with the help of Net Meter. And if you used more than you generated, then you will be paying only for those units of power.
For example, if you generated 200 units of Solar power and you consumed 250 units of power, then you will be paying only for the remaining 50 units to the government.
- No wastage of Solar Power.
- No maintenance
- 100% Green Energy
- Power Bills will be reduced drastically.
- When there is power outage, the On-Grid inverter will get turned off.
- Paper work is involved, as we need a Solar Net Meter which will be issued by Government.
Off-Grid Solar Energy System
An Off-Grid Solar system is a system which consists of a battery for back-up power. This system charges the battery with the help of solar panels that are installed on your rooftop. The power generated from Solar Panels will be transferred to off-grid solar inverter and from this, Solar battery will get charged. Whenever there is a power outage, the off-grid inverter draws power from the battery and delivers it to the specified loads like Lights, Fans and TV's. More likely, off-grid system works just like as a normal inverter system that we already have in our homes. But the big difference is, instead of the grid-power, batteries will get charged from Solar Panels.
- Just like normal inverter, whenever there is a Power Outage, we run our home appliances.
- During full cloudy days, if there is no Solar power, batteries will get charged by Grid-Power.
- Since there is battery, this is not a zero maintenance system.
- Once battery is full and the appliances that are connected to this inverter line is turned off, then the solar power that is generated will get wasted.
So that's the difference between both the kind of Solar energy systems. And if you ask me which kind of system to choose, I would ask you about the kind of power cuts you are having. If you have frequent and long hour power cuts, I just you to go with Off-Grid system. And if you don't have any frequent or long hour power cuts, I strongly suggest you to go with an On-Grid system. I hope this article would have given you an idea on the kind of system that fits for your requirement.
