Economic Feasibility of Solar Energy
Installing a solar power system (5 to 10 kW) requires a one-time payment, but the system generates electricity for more than 25 years. Although the initial cost might seem high, the investment pays off in 5 to 8 years. After that, the electricity is virtually free.
Comparison: Grid Electricity vs. Solar Power
Item | Grid Electricity | Solar Power |
---|---|---|
Monthly Cost | Continuous and increasing | Close to zero after install |
Annual Price Increase | Yes, depending on government | None |
Benefit Duration | Ongoing usage | About 25 years |
Fuel Dependency | High | None |
Environmental Impact | Moderate pollution | Eco-friendly |


Practical Example
A person using 100% electricity from the grid pays 100% over 10 years. With solar power, they pay 10% only in year one, then 0% in the following years. That means solar energy can save over 90% of electricity costs over time.
