How to compare three Pinellas Park solar quotes without getting fooled
Five numbers make any two proposals comparable. Everything else on the page is decoration.
Three proposals, three different formats, three different panel brands. Here's how to flatten them into a real comparison.
1. Modeled first-year production in kWh
Not system size in kW — production. Two 8 kW systems on different planes with different shade produce different energy. If a proposal doesn't state modeled kWh, it isn't a proposal.
2. The degradation assumption
Panels lose a small fraction of output annually. If one bidder models 0.25%/year and another models 0.5%/year, their 25-year savings figures diverge substantially from identical hardware. Compare the assumption, not the conclusion.
3. Exclusions
Read the exclusions section first. The usual suspects in Pinellas Park:
- Electrical panel or service upgrade
- Roof repair or decking replacement discovered at install
- Tree trimming
- Any HOA or architectural review fees
4. All-in installed cost and cost per watt
Total after every fee. Divide by system watts. That's your comparison number across bidders.
5. Financing structure
Cash, lease and prepaid lease produce entirely different cash-flow curves from the same equipment. Compare the structure you'd actually use, against your real Duke bill.
The question that reveals the most
"What's your estimate for my roof's remaining life, and is a re-roof included?" A bidder who hasn't looked closely enough to answer hasn't looked closely enough to quote.
