Why Solar Makes Financial Sense
The Problem: Escalating Energy Costs
$69,007
- Current annual bill for your property w/estimated missing data.
- Utility rates from SCE are increasing by close to 6% annually.
- For our financial modeling, we used a 5% increase for conservative projections.
Data source: CA Solar & Storage Association
The Solution: Solar Energy as Your Financial Hedge
- Solar investment protects you from rising utility costs.
- Savings grow and compound over time.
- Locks in lower energy prices as electricity costs rise.
- Leads to significant and increasing financial returns year after year.
The Result: Drastic Reduction in Annual Bill
$33,145
- This new annual bill reflects significant savings after going green.
- Remaining bill due to non-bypassable charges and current battery limitations.
- Optimized approach targets the highest return on investment.
ANNUAL
ELECTRIC BILL SAVINGS:
$35,862
Design - Rooftop Solar
- Reduction in system size from 107 kW to 94 kW due to crickets on the perimeter.
- Designed to comply with fire code and regulations
- Ballasted hybrid system to minimize roof penetrations
- We work with your roofer to maintain warranty coverage
- Conservative weather model ensures realistic energy output projections
- 13-inch row spacing for easy maintenance access
Proposal Updates & Refinements
Based on our recent site walk and updated data, we've refined our proposal to ensure maximum efficiency and return on investment.
1
System Size Optimized
Solar system size adjusted from 107 kW to 94 kW (-13 kW) to accommodate roof "crickets" and maintain fire code compliance. This ensures optimal panel placement and long-term performance.
2
Improved ROI Projections
Updated interval data reveals a greater increase in your utility bill than initially projected.

Flexible Financing Solutions
We've included two cash flow options: the Sunstone Loan, offering a low interest rate (with dealer fee), and a direct Cash Price of $470,188. The Sunstone Loan is our recommended cash flow solution unless you secure a more favorable loan independently.
Cashflow - Solar + Battery (Yotta)
Sunstone Special Payment Loan - 0 DOWN - Low Interest (4.99%)-
20 year
Cash Flow Column Explanations:
Sunstone Loan
Total amount of loan payment each year. Actual loan payment would be monthly.
O&M
Estimation of Solar Panel Cleaning and thorough site analysis once per year and battery replacement in year 16.
Special Payment
In year 2, you would pay the entire Direct Pay Tax Credit back to the loan to re-amortize it, lowering future payments and keeping cash flow strong.
Electric Bill Savings
- Annual electricity cost reduction from solar generation
- Increases 4.5% roughly - utility rate 5% escalation minus 0.5% panel degradation
Grid Services
- Revenue from reducing energy demand during peak grid stress events
- Paid for load reduction during high demand periods (1-5 hour events)
- Automated setup - money deposited directly via Energy Toolbase
- Estimates vary due to market conditions
CA LCFS REC Income
- Renewable Energy Credits paid annually based on solar system generation
- Market rates typically estimated at $2-13/MWh
- Automated setup - money deposited directly via Energy Toolbase
- Estimates vary due to market conditions
Federal Tax Effect
- Federal: 40% tax Direct Pay (30% base + 10% energy community adder)
Total Cash Flow
- Sum of all revenue sources minus costs and tax effects
Cumulative Cash Flow
- Running total showing system payback progression and long-term returns
Cashflow - Solar + Battery (Yotta)

Utility Analysis
Understanding the Time-of-Use (TOU) rate schedules, seasonal charges, and demand charges is crucial for optimizing energy consumption and maximizing the financial benefits of solar energy. Our proposal accounts for these complexities to provide accurate savings projections.
System Specifications
Solar Array
Our system comprises high-efficiency Tier 1 solar panels, delivering a robust 100.9 kW system size for maximum energy capture.
Yotta Microinverters
Benefit from panel-level monitoring and optimized energy harvest with microinverters, ensuring peak performance for each panel. No shading problems compared to string inverters.
Yotta Battery Storage - *Optional Under Loan Model or Cash - NOT PPA
Yotta battery system provides reliable energy storage, ingeniously installed directly under the panels to save valuable ground space.
* note - Battery is NOT included in this model due to it making the PPA model less financially favorable. If the loan option is favorable, we can show comparison with the battery.
