Pricing for solar panels is quite complex.  The price will mostly involve:<p>- The state of the roof (does it need reinforcing? will the installers need scaffolding?)
- The complexity of the installation (lots of little roof sections with earth tiles and 2 or 3 transformers? Or a plain and simple one-transformer south facing asphalt roof?)
- Does the crew need to drive 5h from headquarters? Or just 1h?
- A 3kW installation may be worthwhile in some locations but not in others.<p>And finally since solar city depends on the performance of the panels (which they sell as debt), they must ensure that your house will be a good candidate.  If it&#x27;s not, they don&#x27;t want you as a customer.
