Path-Q Solar
How many solar installers should I contact before choosing a proposal?
Answer
There is no universal correct number, but obtaining several comparable proposals is usually more informative than relying on one. The useful goal is enough qualified bidders to identify differences in design, scope, price, warranties, and assumptions.
Key points
- Prioritize qualified, appropriately licensed and insured installers over a high volume of unvetted quotes.
- Use the same basic project requirements and request itemized, comparable proposals.
- Compare design quality, production assumptions, contract terms, permitting, interconnection handling, warranties, and references.
- A very low price should be investigated for omitted equipment, labor, permits, or service.
What it depends on
- Project complexity
- Availability of qualified local providers
- Roof or site conditions
- Need for storage, structural work, or service upgrades
- Time available for comparison
Risks and trade-offs
- More proposals improve comparison but can create confusion if assumptions differ.
- A narrow provider pool may be appropriate for unusual or complex projects.
- Choosing solely on price can increase quality, schedule, and warranty risk.
Information you may need
- Comparable system specifications
- Installer qualifications and references
- Itemized prices and exclusions
