Why 40% of Solar Installations Fail (And How to Check Your Roof First)

40% of solar installs underperform due to seasonal shade. SolrScan's $19 satellite report reveals your roof's true solar potential before you commit.

The Shade Trap

Your roof looks perfect for solar. Big, open, facing south. The installer agrees. They sign the contract. Panels go up.

Then the bill comes.

It is not what you expected.

The problem is seasonal shade. Trees that look short in June cast long shadows in December. A neighbor's house that seemed fine from the street blocks your west-facing panels at 3 PM in winter.

You do not need an installer's opinion. You need satellite data that simulates shade across all four seasons.

How SolrScan Works

SolrScan uses satellite imagery to model your roof's sun exposure month by month. You get a report that shows:

  • Shade analysis for every season
  • Estimated annual production based on your roof's actual orientation and tilt
  • Panel count and sizing recommendations
  • Roof age assessment from satellite imagery

The report costs $19. It is delivered instantly. No sales call. No pressure. Just data.

Why This Matters

Before you talk to an installer, you need to know if your roof is actually viable. A $19 report saves you from a $25,000 mistake.
