Solar Rooftop Guide
Five Pillars

Almost every question about commercial solar rooftop falls into one of five groups — is it worth it, how permitting works, what the system needs after it goes live, what the capital budget looks like, and how much surplus power can be sold back. This page splits the guide along those five lines so you can start from the pillar that matches your question instead of reading the whole library.

Pillar 1 · Is it worth it

What actually decides whether a given roof pays back — the share of power used during daylight hours, a system size matched to the real load, and the site conditions that change the answer.

Pillar 2 · Permitting

Which authorities you file with, the documents that most often stall an application, and the order of the steps from filing to grid connection approval.

Pillar 3 · After installation

What the system needs once it is running — panel cleaning, reading the monitoring data, the signals that something is wrong, and the work that runs on a schedule.

Pillar 4 · Capital budget

What the upfront figure is made of, what makes two quotations differ, and the line items that hurt later if they are cut.

Pillar 5 · Net billing

Where the power you do not use goes, the conditions of the buy-back scheme, and what has to be in place before surplus can be sold back.
