All-in-one
Complete Kits
Panels, inverter, racking and wiring pre-matched in one package. You give up some flexibility and usually pay slightly more per watt, in exchange for removing every compatibility question.
What to compare
- Whether a permit-ready plan set is included — worth real money
- Whether the inverter is on your utility's approved equipment list
- What is genuinely in the box versus sold separately
- Whether it meets rapid-shutdown requirements for a roof array
How to size it
A kit is sized the way any system is: annual consumption divided by peak sun hours, plus a margin for losses. The difference is that the compatibility work has been done for you — panel voltage matched to the controller window, inverter matched to the bank, racking matched to the module frame. That is worth real money in avoided mistakes, particularly on a first build. What you give up is the freedom to substitute a component, and you usually pay slightly more per watt.
Mistakes that cost money
- Assuming everything is in the box
- Kits routinely exclude wiring, conduit, disconnects, fuses, grounding hardware and mounting for your specific roof. Read the parts list line by line and price the gaps before comparing kits on headline cost.
- Overlooking the permit plan set
- Some kits include a stamped, permit-ready plan set and some do not. Having one drawn up separately costs real money and weeks of calendar time, so a kit that includes it may be cheaper than a nominally cheaper one that does not.
- Not checking the utility's equipment list
- For a grid-tied kit, the inverter has to be on your utility's approved list. A kit that is perfect on paper is useless if the interconnection application is refused.
- Buying a kit for a roof that was never surveyed
- Kits are sized for an idealised roof. Shading, orientation, available area and structural capacity are specific to your building, and none of them are in the box.
