Energy-as-a-Service Model:
- Provider installs solar panels (€0 to you)
- Provider owns equipment
- Provider maintains system
- Provider assumes technology risk
- You enjoy savings from Day 1
The Key Difference: Capital vs Operating Expense
Traditional: CAPEX (capital expenditure) – you finance asset
EaaS: OPEX (operating expenditure) – you purchase service
Business Model Shift:
- Customer: Pays nothing upfront, saves money immediately
- Provider: Invests capital, earns returns over 20-25 years
- Investor: Funds providers, earns 12-25% returns
The Three Main EaaS Models
Model 1: Power Purchase Agreement (PPA)
Structure:
- Provider installs solar on your roof (€0 to you)
- Provider owns and maintains system
- You purchase electricity generated at contracted rate
- Rate: Typically 10-30% below utility rate
- Contract: 20-25 years
Example:
- Your utility rate: €0.20/kWh
- PPA rate: €0.14/kWh (30% discount)
- System generates: 8,000 kWh/year
- Your payment: 8,000 × €0.14 = €1,120/year
- Utility would cost: 8,000 × €0.20 = €1,600/year
- Your savings: €480/year with €0 invested
Escalator Clause:
- PPA rate typically increases 1-3%/year
- Still beats utility (which increases 3-5%/year)
- Long-term savings remain positive
Provider Revenue:
- Year 1-25: Your payments (€1,120/year × 25 = €28,000)
- Tax credits: 30% ITC (€5,400)
- Accelerated depreciation: €3,000-5,000
- Total revenue: €36,400-38,400
- System cost: €18,000
- Gross margin: €18,400-20,400 (102-113% return over 25 years)
- Annual return: 12-18% (depending on financing cost)
Who Benefits:
- Customer: €480/year savings, €12,000 over 25 years, €0 invested
- Provider: 12-18% annual returns
- Society: 8 tons CO₂/year avoided
Best For:
- Homeowners with high electricity bills (>€100/month)
- Good credit (640+)
- Suitable roof
- Want maximum savings with €0 down
Model 2: Solar Lease
Structure:
- Provider installs solar on your roof (€0 to you)
- Provider owns and maintains system

- Contract: 20-25 years
Example:
- Your current utility bill: €150/month
- Solar would generate: 70% of your electricity
- Lease payment: €85/month (fixed)
- Remaining utility bill: €35/month (30% still from grid)
- New total: €120/month (vs €150 before)
- Your savings: €30/month = €360/year with €0 invested
Predictability:
- Fixed monthly payment (unlike PPA which varies with generation)
- Easier budgeting
- Small escalator (0-2%/year typically)
Provider Revenue:
- Year 1-25: Your payments (€85/month × 300 months = €25,500)

Model 3: Community Solar (Solar Gardens)
Structure:
- Provider builds large solar farm (1-20 MW)
- Divided into “shares” (e.g., 500 subscribers × 10 kW each = 5 MW)
- You subscribe to portion (e.g., 5 kW)
- Farm generates electricity → sold to grid
- You receive credit on utility bill (10-20% discount)
Example:
- You subscribe to 5 kW share
- Monthly subscription: €40
- Generates: 600 kWh/month × €0.20 = €120 credit
- Net benefit: €120 – €40 = €80/month
- Your utility bill: €150 – €80 = €70
- Your savings: €80/month = €960/year with €0 down
Advantages:
- No roof needed (renters, condos, apartments eligible!)
- No home installation
- Move? Transfer or cancel subscription
- Immediate savings
- Low commitment (monthly or annual contracts)
Provider Revenue (Large Solar Farm):
- 5 MW farm cost: €4-6 million ($800-1,200/kW)
- 500 subscribers × €40/month × 12 months × 25 years = €6,000,000

- Buyout option: Yes/No @ €_____
Red Flags to Watch:
- Escalator >3%/year (beats utility increases?)
- No buyout option (locked in)
- Non-transferable (problem if you sell home)
- Hidden fees (interconnection, monitoring, etc.)
- Poor reviews (check BBB, Google, Solar Reviews)
Day 18-19: Check References
For your top 2 providers:
- Read reviews: Google, BBB, Solar Reviews website
- Ask provider for customer references (3-5)
- Call references:
- Are you happy with the system?
- Any issues?
- How’s customer service?
- Savings as expected?
- Would you recommend?
Day 20-21: Legal Review
Critical: READ THE CONTRACT CAREFULLY
Key sections:
- Performance guarantee (what if system underproduces?)
- Maintenance (who pays for repairs?)
- Insurance (who’s responsible for damage?)
- Termination (can you cancel? Fees?)
- Transfer (what if you sell home?)
- Buyout (what’s the buyout price formula?)
- Escalator (how much do rates increase?)
Consider: Have lawyer review (cost: €300-500, worth it for 25-year contract)

The Crisis Reality: 70-80% of Population Blocked from Clean Energy
The Accessibility Crisis
Current Solar Adoption:
- US: 4% of homes have solar
- Europe: 5-8% (varies by country)
- Global: <2% residential solar penetration
Why So Low Despite:
- Solar now cheapest electricity in history
- 20-30% savings vs utility rates
- Environmental benefits obvious
- Technology mature and reliable
The Barriers (Why 96% Haven’t Gone Solar):
Barrier 1: Capital Requirements ($15,000-30,000)
Traditional solar costs:
- System: $15,000-25,000
- Installation: $2,000-5,000
- Permits: $500-1,000
- Total: $17,500-31,000
- After 30% tax credit: $12,250-21,700
Reality:
- Median US household savings: $8,000
- 40% of Americans can’t cover $400 emergency
- 70% can’t afford $12,000+ upfront cost
Even with loans:
- Requires good credit (680+)
- Monthly payments $150-250
- Still a financial commitment
- Excludes 30-40% of population
Barrier 2: Homeownership Requirement
Renters excluded:
- US: 36% of households rent
- Urban areas: 50-60% rent
- Young adults: 70%+ rent
- None can install rooftop solar
Even homeowners face issues:
- HOA restrictions (15% of homes)
- Structural concerns (10% need roof repairs first)
- Unsuitable roofs (20% – shading, age, orientation)
Result: 65-70% of population structurally excluded from traditional solar
Barrier 3: Credit Score Requirements
Traditional solar loans:
- Require 680+ credit score (prime)
- Exclude 40% of population with <680 score
- Subprime (580-680): Higher rates or denial
- No credit history: Excluded
Income requirements:
- Many lenders require verification
- Self-employed face additional hurdles
- Gig economy workers often excluded
Barrier 4: Information Asymmetry
Complexity overwhelms consumers:
- Technology: kW vs kWh vs efficiency ratings
- Financing: PPA vs lease vs loan vs cash
- Incentives: Federal, state, local, utility (confusing!)
- Installers: 1,000s of companies, quality varies widely
- Contracts: 25-year agreements, complex terms
Result:
- Decision paralysis
- Fear of making expensive mistake
- Default to status quo (do nothing)
Sales practices:
- Aggressive door-to-door sales
- Pressure tactics
- Bait-and-switch pricing
- Creates distrust
