Commercial Solar & Battery Storage: From Planning to Completion

Keep this article handy
In this article

For many Canadian businesses, electricity is a major operating expense.

As energy demands increase and businesses look for ways to manage long-term costs, commercial solar and battery energy storage are becoming important options for property owners, manufacturers, retailers and industrial facilities.

At Stellr Solar, we design energy systems around each customer's property, electrical requirements and financial objectives.

Whether you're considering a commercial rooftop solar installation, a larger industrial project or an integrated solar and battery system, our team can help evaluate the opportunity.

Commercial Solar & BESS

Why Are Businesses Investing in Solar?

Commercial solar can provide several potential advantages.

Lower Electricity Expenses

Solar generation can reduce the electricity a business needs to purchase from the utility.

The value of the electricity produced depends on the customer's tariff, consumption patterns and permitted export arrangements.

Greater Long-Term Cost Predictability

Generating a portion of your electricity on-site can reduce exposure to changes in the price of purchased electricity.

While future utility rates cannot be predicted with certainty, solar can provide a source of electricity with relatively predictable long-term operating characteristics.

Environmental & Sustainability Benefits

Solar generation can reduce reliance on grid electricity and support a business's sustainability goals.

The environmental benefits depend on the local electricity system and how the project's energy and environmental attributes are accounted for.

Long-Term Infrastructure Investment

A professionally designed solar installation is a long-term energy asset.

Many modern solar panels carry manufacturer performance warranties extending over several decades, subject to the specific equipment selected.

Step 1: Understanding Your Business's Electricity Consumption

Before designing a commercial solar system, we review how your business uses electricity.

We may request:

  • Twelve months or more of electricity bills.
  • Energy consumption in kWh.
  • Maximum monthly electricity demand.
  • Interval meter data, where available.
  • Existing electrical service information.
  • Operating schedules.
  • Roof or site drawings.
  • Planned business or facility expansion.
  • Backup power requirements.
This allows us to evaluate the solar opportunity using the property's actual operating conditions.

Understanding Energy Charges vs. Demand Charges

Many commercial electricity tariffs contain two different types of variable charges.

Charge

How it works

Energy charge

Based on electricity consumed, measured in kWh

Demand charge

Based on the highest qualifying electrical demand, measured in kW or kVA

For example, a business may have moderate total electricity consumption but experience a short period of very high demand when several pieces of equipment operate simultaneously.

Depending on the utility tariff, that peak can contribute substantially to the monthly bill.

Solar generally reduces purchased energy. Demand-charge savings require reducing the actual billed peak.

This distinction is important when calculating commercial solar savings.

Step 2: Commercial Solar System Design

Our team evaluates the property's available solar installation areas.

Potential options include:

  • Commercial rooftop solar.
  • Ground-mounted solar.
  • Solar carports.
  • Solar combined with batteries.
  • Hybrid systems incorporating suitable generators and energy controls.

We consider available space, shading, structural conditions, utility requirements and expected electricity production.

The objective is to develop an appropriately sized system aligned with the customer's energy needs.

Step 3: Evaluating Battery Energy Storage

Battery Energy Storage Systems (BESS) can provide additional capabilities beyond solar generation.

Peak Demand Management

A battery may discharge electricity during periods of high demand, reducing the peak recorded by the utility.

The actual financial benefit depends on the demand tariff, battery capacity, power output, load profile and control strategy.

Peak Shaving

Backup Power

Battery systems with compatible backup equipment can provide electricity to selected equipment or supported facility loads during outages.

Backup duration depends on the battery system and the electricity required by the business.

Energy Management

Batteries may be programmed to charge and discharge according to approved operating strategies.

Possible objectives include improving on-site solar consumption, managing time-of-use costs and supporting selected operational requirements.

Battery Capacity vs. Power Output

Two measurements are especially important:

Measurement

What it tells you

kW

How much power a battery can supply at a given moment

kWh

How much energy the battery can store

A battery with substantial energy capacity may still have limits on the amount of power it can deliver at once.

Both values must be considered when designing peak-shaving and backup systems.

Step 4: Commercial Financial Analysis

Every project should be evaluated using its own financial assumptions.

A commercial solar assessment may include:

  • Installed project cost.
  • Estimated annual electricity generation.
  • Expected reduction in grid electricity purchases.
  • Electricity rate assumptions.
  • Demand charge considerations.
  • Maintenance and operating costs.
  • Financing assumptions.
  • Available tax incentives.
  • Expected long-term cash flow.
  • Estimated return on investment and payback.

For battery projects, additional analysis may include hourly or shorter-interval electricity demand data, battery performance assumptions and dispatch modeling.

Financial results are estimates based on the information available at the time of analysis.

BESS Benefits

Step 5: Financing & Tax Incentives

Depending on the project and customer, there may be opportunities to use financing or tax incentives to improve project economics.

Potential structures include:

  • Direct business ownership.
  • Commercial equipment financing.
  • Business loans or lines of credit.
  • Third-party ownership arrangements.
  • Power purchase agreements, where suitable.
  • Other project-specific financing structures.

Federal Clean Technology Investment Tax Credit

Qualifying clean technology investments may be eligible for a refundable federal investment tax credit.

For eligible projects in 2026, the available credit can be up to 30% of qualifying capital costs, provided the applicable eligibility and labour requirements are satisfied.

The credit is not available automatically to every customer or project.

Capital Cost Allowance

Certain eligible clean energy equipment may also qualify for capital cost allowance treatment under Canadian tax rules.

The amount and timing of tax deductions depend on the applicable legislation and the taxpayer's circumstances.

Customers should consult their tax advisors to confirm eligibility and understand the interaction between deductions, credits and other incentives.

Step 6: Engineering & Feasibility Review

Once the project advances beyond the initial assessment, additional engineering may be necessary.

This can include:

  • Structural engineering.
  • Electrical design.
  • Load calculations.
  • Equipment specifications.
  • Ground-mount or rooftop mounting design.
  • Interconnection protection requirements.
  • Battery system engineering.
  • Fire and electrical safety considerations.

Some projects may also require additional municipal, environmental or site-specific approvals.

Step 7: Utility Interconnection & Permitting

Commercial solar must comply with applicable utility connection and electrical safety requirements.

In Nova Scotia, qualifying commercial net-metering projects above the smaller self-generation threshold may require a formal utility interconnection application.

Larger projects may also require utility studies and additional agreements.

The time needed for approval depends on project size, utility requirements and local grid conditions.

Our team coordinates the applicable technical documentation and approval stages.

Step 8: Procurement & Installation

Once the project is appropriately approved and ready for construction, equipment procurement and installation scheduling can proceed.

A commercial installation may involve:

  • Roof or ground-mount preparation.
  • Solar mounting structures.
  • Solar panels.
  • Inverters.
  • Electrical distribution equipment.
  • Cable routing and trenching.
  • Battery systems.
  • Energy management controls.
  • Utility interconnection equipment.

For operating businesses, installation schedules should consider access, site safety, production activities and planned electrical interruptions.

We work with the customer to develop an installation plan suited to the property and operating environment.

Step 9: Inspection, Commissioning & Activation

After construction, the system must complete applicable testing, inspections and utility acceptance requirements.

Commissioning activities may include:

  • Checking system operating parameters.
  • Verifying equipment communication.
  • Confirming monitoring functionality.
  • Reviewing electrical protection and controls.
  • Testing supported battery operating modes.
  • Completing required utility acceptance procedures.

The system enters normal operation once the necessary conditions have been satisfied.

Step 10: Monitoring & Long-Term Performance

After activation, monitoring can provide useful information about the system's performance.

Depending on installed equipment, customers may be able to review:

  • Electricity generated by solar.
  • Inverter performance.
  • Battery operation.
  • Energy consumption.
  • Grid imports and exports.
  • System alerts and operating status.

Commercial customers may also benefit from reviewing utility demand charges and energy costs alongside production data.

For larger systems, a structured inspection and maintenance plan may be appropriate.

How Long Does a Commercial Solar Project Take?

Stellr Solar generally plans for approximately 4–8 months for typical commercial projects.

More complex installations may take longer because of engineering, permitting, utility studies, equipment lead times or construction conditions.

We'll develop a more specific project schedule once the scope and requirements are established.

Does Every Business Have the Same Solar Opportunity?

No.

The economics of commercial solar vary significantly between businesses.

An office building, restaurant, warehouse, manufacturer and industrial processing plant may have very different energy consumption patterns.

Important considerations include:

  • Electricity tariff classification.
  • Annual consumption.
  • Peak electrical demand.
  • Operating hours.
  • Solar installation space.
  • Export and net-metering eligibility.
  • Financing and tax circumstances.

We believe every project should be evaluated based on its own operating conditions rather than relying on generic savings assumptions.
