Solar Panel Cleaning Business Bookkeeping: Turning Soiling-Loss Data Into a Recurring-Contract Pricing Model

NREL data puts solar soiling losses at ~5% of output nationally and 25%+ in dusty climates — the basis for pricing 2–4 cleanings a year. How solar panel cleaning operators should book prepaid annual contracts as deferred revenue, track fuel and water per job to capture 15–25% route-density gains, and record DI systems and fall-protection gear as Section 179-eligible assets.

Substack and Newsletter Writer Taxes: Schedule C, the Hobby-Loss Trap, and What You Can Deduct

Paid newsletter revenue on Substack, Ghost, or beehiiv is Schedule C self-employment income — owing 15.3% SE tax, quarterly estimates once you owe over $1,000, and facing a new 90% cap on hobby-expense deductions in 2026. Here's how the 1099-K thresholds, the 13–19% effective platform-fee cost, and the deduction rules actually work for writers.
