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.

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.

Conclusion

Solar energy is a smart long-term investment. Despite the upfront cost, it ensures energy independence, major savings, and a clean, renewable power source.
