Rooftop Solar vs Grid Power: For some time now, there has been a significant emphasis on solar power across the entire country. Nowadays, solar panels can be seen everywhere—from residential homes to industrial factories. While many have fully embraced solar power, the need for grid-supplied electricity still persists. In many instances, the reliability of grid-supplied electricity is unmatched; however, when it comes to cost, solar power systems prove to be the more economical option.
Rooftop Solar vs Grid Power: Find Out Which Option Is Best
How Does It Work?-
Solar panels installed on a home's rooftop convert sunlight into electricity. Subsequently, with the aid of an inverter, this electricity is conditioned to power household appliances. In addition to storing this generated electricity, it can also be fed back into the grid. Conversely, grid electricity is generated at power plants and transmitted to homes via high-voltage transmission lines and substations.
Cost-
In terms of upfront expenditure, solar panels tend to be relatively expensive; that is, installing a solar energy system requires a significant initial investment. The installation cost typically ranges from ₹45,000 to ₹60,000 per kilowatt, whereas grid electricity presents no such financial hurdle. To obtain a grid connection, one simply needs to pay an initial security deposit. The cost of the remaining infrastructure is borne by the electricity supply companies or the government.
Cost Per Unit-
When electricity is drawn from the power grid, consumers may face bills ranging from ₹6 to ₹15 per kilowatt-hour (unit). This rate varies depending on the specific state or the electricity supply company. Furthermore, these rates generally tend to increase year after year. On the other hand, solar panels eliminate the hassle of recurring monthly bills. When the total cost of the solar system is amortized over time, the actual cost per unit works out to be between ₹3 and ₹4.
How Long Does It Take to Recover the Cost?-
The initial investment made in solar panels is typically recovered within 2 to 5 years. This timeframe depends on various factors, such as electricity consumption levels and government subsidies received. However, this principle does not apply to grid electricity; with grid electricity, monthly bills must be paid continuously for as long as electricity is being consumed.
Which Option Is Cheaper?-
Although installing a solar energy system entails a higher upfront cost, this investment is fully recouped within 2 to 5 years. Once installed, the system can operate reliably for 20 to 25 years. Viewed from this perspective, you can benefit from highly affordable electricity for two decades. Conversely, grid electricity charges tend to rise continuously over time. Therefore, over a period of 20 to 25 years, grid electricity proves to be the more expensive option.
