Financing

Residential Options

• Cash purchase: highest ROI, 6-10 year payback
• Solar loan: $0 down, 12-25 year terms, 4-9% APR (GoodLeap, Mosaic, Sunlight Financial)
• Lease: customer pays fixed monthly, no ownership
• PPA: pay per kWh generated, no upfront cost
• Dealer fees: 15-30% of project cost (baked into loan rate)

Commercial Options

• PPA: most common, off-balance-sheet
• Capital lease: ownership at end of term
• PACE (Property Assessed Clean Energy): repaid through property tax
• MACRS depreciation: 5-year accelerated + bonus depreciation

Growth Playbook

Phase 1: Foundation (0-50 installs/year)

• Focus on residential in 1-2 markets
• Build referral network: roofers, electricians, realtors
• Nail the install process before scaling
• Get NABCEP certified

Phase 2: Scale (50-200 installs/year)

• Add dedicated sales team
• Digital marketing: Google Ads, solar review sites
• Subcontractor network for overflow
• Add battery storage as standard offering

Phase 3: Expansion (200-500 installs/year)

• Enter commercial market
• Multiple crews running simultaneously
• In-house design and engineering team
• Regional expansion or franchise model

Phase 4: Market Leader (500+ installs/year)

• EPC for commercial/utility scale
• O&M (Operations & Maintenance) recurring revenue
• White-label installer for national brands
• Energy storage and EV charging integration

Common Pitfalls

• Underestimating permitting timelines (varies wildly by AHJ)
• Over-reliance on dealer fee financing (margin erosion)
• Not tracking cost-per-watt by project (can't optimize what you don't measure)
• Ignoring roof condition (warranty liability if roof fails)
• Poor change order management (scope creep kills margins)
• Not building recurring revenue (O&M, monitoring, battery upgrades)
