The cheapest-looking quote may not be the cheapest project
Two solar proposals can show a similar system size and still describe very different projects. One may include roof repairs, electrical upgrades and night work; another may leave those items outside the headline price.
That is why a single cost-per-watt number can hide more than it reveals, especially on a working venue. The arena canopy case is a good example of how structure and site work can reshape the budget.
Compare the whole scope
Put the same categories side by side: solar equipment, structure, roof work, civil work, cabling, switchgear, design, permits, access, commissioning and venue-specific logistics. Only then does the comparison become useful.
Give uncertainty its own line
Older roofs, undocumented electrical rooms and tight event calendars create uncertainty. Hiding that uncertainty inside a contingency percentage makes it harder to manage. Naming the unknowns helps the venue decide what to investigate before procurement.
A good budget helps make decisions
The budget should show what changes if the venue chooses roof solar, canopies or a smaller first phase. For the revenue side, pair that work with the tariff-first economics guide rather than a generic payback promise.
Put every bid on the same scope before comparing prices. Anything excluded today can return later as an expensive extra.
