Commercial Installation

At Maxum Energy, one of our main specializations is commercial, spanning from 20kW to 1,000kW+ in size. As a result, we are well-versed in organizing larger-scale jobs and understand the workload needs on the site.

Combined with premium solar modules and inverters equals a recipe for success with high, long-term energy savings.

Step 1: Site Visit

We perform a virtual or physical site visit to note the locations of the main electric panel, any sub-panels, and the roof space or ground proposed for the system. If battery modules are also being added, we must find a suitable location depending on size and capacity. 

Step 2: Size Finalization

After we have all the necessary information to proceed and you have confirmed the system size, we will prepare a contract for you to review and sign.

Once a contract has been signed and the deposit has been made, we:

•Generate plans

•File the interconnect application with the utility

•Apply for city permits, any rebates, and tax credits.

•Work with any HOAs to receive and file paperwork with city permits (if applicable)


Step 3: Scheduling and Day of Installation

The following will happen after interconnecting applications and city permits have been approved.

•Schedule delivery for modules and batteries (if applicable)

•Schedule installation within a non-conflicting day/time when the power can be turned off for an extended period

•If there is any need to reschedule, please get in touch with us at least 48 hours before installation



•On installation day, we will need a free and clear access point to the roof and any electric panels

•The modules/battery units will arrive on a pallet, so we require a cleared space sectioned off, ideally near a roof access point.

•Our work-site vehicles will need access to unload and load any tools/materials

•Systems 20-80kW typically take 4-10 business days, depending on the complexity

•Larger systems can take up to 10+ business days, depending on specific variables

Step 4: Final Inspection

After a successful installation, we work to schedule a date to inspect the system and receive Permission to Operate (PTO) after approval.

•Once approved, the final payment portion is due

•The 10-year parts and labor warranty for your system and the two-year roof penetration warranty begins

•If you have any questions throughout the process or after installation please get in touch with us
