Why Solar Makes Financial Sense
1
The Problem: Escalating Energy Costs
Utility rates are increasing by ~6% annually. Our financial modeling uses a 5% increase for conservative projections.
$147,695
Your current annual electricity bill.
2
The Solution: Solar as a Financial Hedge
  • Protects you from rising utility costs.
  • Locks in lower, predictable energy prices.
  • Savings grow and compound over time.
  • Ensures significant and increasing financial returns.
3
The Result: Dramatic Bill Reduction
$74,202
Your new annual bill reflects significant savings after going green.
ANNUAL ELECTRIC BILL SAVINGS:
$73,493
4
The Impact: Massive Long-Term Savings
Choosing to go solar avoids the escalating cost of doing nothing.
COST OF DOING NOTHING (30 YEARS):
$4,442,594
Our Approach
50% Tax Credit
USA Products
Conservative Utility Escalation
5% vs 6% historical average (SCE)
Conservative Weather Models
Realistic production projections
Realistic Cashflows
Built-in safety margins
Domestic Content Tax Credits
We pursue USA-made products for maximum 50% tax credit (30% base + 10% energy community + 10% domestic content).
Solar-Only Recommendation
  • Works best with PPA (Power Purchase Agreement) option.
  • Battery savings are not significant with current utility rates/usage patterns.
  • Cash/loan options could explore batteries.
  • Domestic content benefits are more significant than current battery savings.
*Most Small Commercial Batteries do not currently meet domestic content standards.
Why Quality Matters for Long-Term Solar Savings
Your savings grow as utility rates rise - not shrink.
  • Utility costs increase ~5% every year, compounding your savings over time
  • The first year may look modest, but the real value comes from decades of avoided rate hikes
  • That's why quality and reliability matter
Quality Components & Installation:
Premium Components
We use premium USA made Solar Panels and top of the line inverters & racking.
Expert Installation
Expert installation means minimal downtime, fewer repairs, and consistent production
Avoid Pitfalls
A cheaper system might save upfront but often fails or underperforms within 3–5 years - eroding your cash flow
Bottom line:
A solar system should be built to last 30+ years, not just look good on paper.
Choose premium equipment and a partner who stands by their work - that's how you maximize true lifetime savings.
Design - Rooftop Solar
  • Designed to comply with fire code and regulations
  • Structurally Engineered
  • Hybrid-Ballasted System
  • Conservative weather model ensures realistic energy output projections

Your 4 Main Paths to Solar
Sunstone offers various interest rate and dealer fee combinations to best suit your financial needs. You can also bring your own traditional financing with your own bank or lender, and we're happy to facilitate that.
1. Cash Purchase
  • Full ownership
  • Eligible for tax credit & depreciation
  • Maximizes long-term savings
2. Power Purchase Agreement (PPA)
  • No upfront cost
  • Third-party owns & maintains system
  • Pay fixed, discounted rate for power produced
  • Ideal if you don't use tax credits
3. Special Payment Loan (20-year)
  • Lower interest rate
  • Best for long-term financing
  • Ownership, eligible for tax credit & depreciation
4. Standard Loan (10-year)
  • Higher interest rate
  • Best for shorter terms or early payoff
  • Ownership, eligible for tax credit & depreciation
Financial Overview (30-Year Cumulative Cash Flow)

Why Act Now?
The Cost of Waiting
Delaying your solar investment carries a significant financial burden:
$6,185
$6,185 lost every month you delay (based on dividing the cumulative 30-year cash flow into monthly average from the PPA option, which is the minimum amount of cash flow out of all the options).
Every month of delay means missed savings and lost revenue potential.
Expiring Federal Tax Credits
The generous federal tax credits that make this investment so attractive are not permanent:

The current federal tax credits for solar and battery storage are scheduled to phase out. Acting soon ensures you lock in these significant incentives.
Don't miss the opportunity to maximize your return on investment.
Environmental Benefits
115,326 Trees
Equivalent impact of planting thousands of trees in your community
17,481,369 Miles
Equivalent to removing this many driven miles from our roads
7,688 Tons CO₂
Total carbon offset over 20 years of system operation
Solar = Instant Property Value
Solar isn't just an energy upgrade — it's a capital improvement that instantly revalues your property and strengthens NOI for any future buyer.
How We Calculate Added Value:
$73,000 annual energy savings ÷ 5% cap rate = $1.47M in added property value
$73K
First-Year Energy Savings
$1.47M
Added Property Value
$4M+
30-Year Cash Flow
Assumes 5.0% cap rate typical for Inland Empire industrial assets (CBRE, 2025). Actual value impact varies based on market conditions and buyer capitalization assumptions.
Project Implementation Timeline

SAFE HARBOR BY DEC 31, 2025 = AVOID THE HEADACHES
Miss This Deadline = Complex, Expensive, Delayed Projects
THE CHOICE: SIGN NOW vs. WAIT UNTIL 2026
REAL EXAMPLE: $10M PROJECT
WHAT FEOC COMPLIANCE ACTUALLY MEANS
Starting 2026, every project must:
  • Audit every supplier's ownership structure back to source materials
  • Verify 40%+ of components come from non-prohibited countries (increases to 60% by 2030)
  • Document supply chain compliance for IRS audits
  • Navigate limited vendor options as most equipment comes from restricted countries
  • Pay premium prices for the shrinking pool of compliant equipment
