Project inputs, not magic numbers
Prepare a solar-lighting brief that can be engineered.
A product label cannot describe your sky, geometry, night schedule or maintenance context. This worksheet helps capture the variables a supplier should ask about.
System map
Follow the energy from site to night.
Each decision affects the next: daylight collection, conversion, storage, control, optical delivery and maintenance.
1. Collect
Project location, seasonal sun, shade, panel orientation and available surface.
2. Store & control
Night schedule, control profile, critical periods and autonomy expectation.
3. Deliver light
Task, geometry, mounting, distribution, glare context and surrounding surfaces.
4. Maintain
Access, replaceable parts, cleaning, inspection and service responsibility.
Interactive worksheet
Build the first-message checklist.
Select the inputs you can provide now, copy the list, and attach drawings or photos separately.
Avoid false precision
Ask for the assumptions behind the answer.
- Which exact model and variant?Keep the identity consistent across quote, sample, specification and documents.
- Which site inputs were used?A design response should refer back to the location, geometry and operating profile.
- What is verified on the sample?Agree the acceptance checks and evidence before scaled production.
- What remains project-dependent?Record exclusions and open questions instead of filling them with assumptions.
