Path-Q Solar
Is it worth getting solar quotes if my roof is heavily shaded?
Answer
Yes, if the actual shade impact or alternative locations is uncertain. A qualified assessment can determine whether the roof remains viable, whether another roof or ground location is better, or whether the expected output is too low to justify installation.
Key points
- Shade changes by time of day and season, so visual impressions alone may be insufficient.
- Ask for shade assumptions and expected production by roof section.
- Tree trimming, layout changes, panel-level electronics, or other design choices may help in some cases but do not eliminate lost sunlight.
What it depends on
- Timing and extent of shade
- Alternative installation areas
- Tree management possibilities
- Electricity use and project economics
Risks and trade-offs
- A proposal may use optimistic shade assumptions.
- Tree removal or trimming can involve cost, safety, property, and environmental considerations.
- A technically feasible system may still be economically unattractive if shade losses are high.
Information you may need
- Shade observations throughout the day and year
- Roof and alternative site options
- Production estimate with shade losses
- Tree or obstruction constraints
Your next step
What to do next
Request proposals that document shade analysis, expected losses, alternative layouts, and total costs before deciding whether the site is viable.
