LUMA vs Solar Energy: Cost Comparison 2024

LUMA vs Solar Energy: Which is More Economical?

In Puerto Rico, the decision between continuing with LUMA or installing solar panels is becoming increasingly clear. With electricity rates continuing to rise and solar technology more accessible than ever, let's analyze the real numbers.

Current LUMA Costs

LUMA rates in 2024:

• Residential Rate: $0.28 per kWh
• Demand Charge: $8.50 per kW
• Additional Charges: $15-25 per month
• Average Total: $150-300 per month

Future Projections

LUMA rates are expected to continue increasing:

• 2024: $0.28/kWh
• 2025: $0.32/kWh (projected)
• 2026: $0.36/kWh (projected)
• 2027: $0.40/kWh (projected)

Solar Energy Costs

Initial Investment

• 5kW System: $17,500
• Tax Credit (30%): -$5,250
• Net Cost: $12,250

Operating Costs

• Maintenance: $200/year
• Insurance: $100/year
• Annual Total: $300

Financial Comparison

Scenario: Home with 800 kWh/month consumption

With LUMA (25 years)

• Year 1: $2,688
• Year 10: $3,840
• Year 25: $5,760
• 25-year Total: $107,520

With Solar Energy (25 years)

• Initial Investment: $12,250
• Operating Costs: $7,500
• 25-year Total: $19,750
• Total Savings: $87,770

Additional Factors

Solar Energy Advantages

• Energy Independence: No grid dependency
• Blackout Protection: With batteries
• Property Value: Increases 3-4%
• Environmental Benefits: Zero emissions

LUMA Disadvantages

• Frequent Blackouts: System vulnerability
• Constant Increases: No control over rates
• Dependency: Total grid dependency
• Environmental Impact: Fossil fuels

Conclusion

Solar energy is clearly the more economical option in the long term. With potential savings of over $87,000 in 25 years, the initial investment pays for itself in less than 5 years.

Beyond financial benefits, solar energy provides energy independence and contributes to a more sustainable future for Puerto Rico.
