Commercial & Industrial Solar
Your Load Profile Decides the Project.
01The Commercial Case
Start With the Bill, Not the Roof.
A commercial solar proposal that begins with available roof area has started in the wrong place. What determines the value of a system is what it displaces: units you would otherwise buy, at the tariff you actually pay, at the times you actually use them.
That means twelve months of bills, your tariff category, demand charges and a realistic picture of your load through the working day. Only then does roof area become the constraint it is often presented as.
We would rather tell a business that its load pattern does not suit a large array than sell it one that underperforms against the numbers it was shown.
02What Drives It
Five Things That Change the Answer.
- Load profile, not just total units
- When you draw power matters as much as how much. A daytime-weighted load suits solar directly; a night-shift operation does not, without a different approach.
- Tariff category and slab
- Commercial and industrial tariffs, demand charges and time-of-day structures all change what a unit of self-generated power is actually worth to you.
- Sanctioned load and connection
- The rules governing commercial connections and the permitted capacity relative to sanctioned load are set by your distribution company.
- Available structure
- Roof type, span, age and load capacity, or ground area if a roof cannot carry the system. Sheet roofs and RCC slabs need different mounting approaches.
- Operational constraints
- Shutdown windows, working at height over live operations, crane access and the plant's own maintenance calendar.
03Configuration
Three Practical Routes.
- Rooftop, self-consumption
- The common starting point: an array on your own roof, sized against daytime load. Lowest disruption and the most direct relationship between generation and bill.
- Ground-mounted on site
- Where roof area or structure limits capacity, and spare land is available within the premises.
- Phased installation
- Building capacity in stages as load grows or budget allows, with the first phase laid out so the second does not require rework.
04Process
How a Commercial Project Runs.
01
Consumption analysis
Twelve months of bills, load pattern, tariff category and demand charges.
02
Structural and site survey
Roof type, span, condition and load capacity, or available ground area.
03
Capacity and layout
What the structure and connection permit, and how it would be laid out.
04
Commercial case
What the system offsets against your actual tariff, with the assumptions stated openly.
05
Approvals and agreements
Distribution company approvals and the applicable connection arrangement.
06
Installation and commissioning
Phased around your operations, with metering and inspection as required.
05Questions
What Businesses Ask.
What payback period should we expect?
We do not quote a payback figure before analysing your bills. Payback depends on your tariff category and slab, demand charges, how much generation you consume on site versus export, the export arrangement available to you, system cost, and your operating pattern. Two businesses on the same street with the same roof area can see materially different outcomes.
Does commercial solar get a government subsidy?
PM-Surya Ghar: Muft Bijli Yojana is a residential rooftop scheme and does not extend to commercial or industrial installations. Other incentives, accelerated depreciation treatment or state-level provisions may be relevant to your business — those are questions for your accountant and the applicable state policy, and we would not represent them as assured.
Will installation interrupt our operations?
Rooftop work is usually planned around operations rather than stopping them, but some activities — crane lifts, electrical tie-in, commissioning — need defined windows. We would rather agree those honestly at the planning stage than discover them during installation.
Our roof is old. Is that a problem?
It can be. The array and its mounting will be on that roof for a long time, so it makes little sense to install over a roof that needs replacing within a few years. A structural assessment comes before any capacity discussion, and sometimes the honest recommendation is to address the roof first.
Can we start small and expand later?
Often yes, and it is frequently sensible. The important thing is that the first phase is laid out, and the electrical infrastructure sized, with the later phase in mind — otherwise expansion means reworking what is already installed.
