Commercial Solar Power for Profit


Commercial solar power makes real economic sense for many businesses, as most power is used during the day. In most cases, solar can increase profitability for your business through savings on power bills.

Smaller businesses often use lighting, heating, air conditioning and computers as a consistent base load. Larger companies may have plant and equipment such as cooking, refrigeration or manufacturing machinery. This is the ideal scenario for solar because you get rid of those daytime high energy use costs.


Return On Investment*

+ 5 Year Payback*

*Sunergy Solar commercial installations often generate a return of around 20% PA, which allows them to effectively pay for themselves within as little as 5 years.  After that you have…

Does your business have a moderate to heavy daytime power consumption? If so, that’s the key to a profitable solar array—because you’ll be saving most of your daytime power bill. Our commercial solar installations are saving enough on power bills to effectively pay for themselves within as little as 5 years.


The sooner you invest in solar energy, the sooner the returns and the greater the savings. Once those savings have paid off the capital cost of the system, from then on you have FREE power!

How will it work for your business?

Following a free site visit assessment, we give you an expected ROI by analysing your site, using NIWA’s historical sunshine data, and current energy prices.

These graphs show an expected return and payback projection based on a 4.16kW system, saving $0.30c per kWh of grid supply.

The sooner you go solar, the greater the return ~ so why hold off on a good investment?

With the solar technology available today, it has become economically viable—and even profitable—to install solar power for many businesses, farms, schools and homes.

Solar Photo Voltaic (PV) systems are cost effective, easy to install and do not require resource or building consent, making them the clear contender for domestic and commercial auxiliary energy production both now and in the future.

Accurate, Customised Data Prediction

In order to design the optimal solar energy system we analyse your site, your power usage and even the way your business operates. We collect real-time, local data on sunshine hours, angles and more to best specify and position the system and array.  Our experience and the data technology we use enable us to give an accurate projection on performance metrics—so you can make an informed decision.

Actual Data Example

This graph shows actual results on a dairy farm we installed in Canterbury.

Light orange (left) was our prediction,

Dark orange & lined (right) was actual production—averaging just above predicted.

Dark orange (right lower) was actual consumption—lower than production.

In this case, solar production was greater each month than power consumed, resulting in maximum energy bill savings, plus a supplementary income from power exported to the grid.


How Solar works for Business

Stay Connected to the Grid

Commercial solar systems are connected to the grid (grid-tied), like residential systems, but are larger, normally from around 10kW, up to hundreds of kW’s. 

Custom Designed

Each Sunergy Solar system is designed specifically for your site based on load data which we log at your premises. We then design match the system size to the power you use as best as possible. 


We then provide ongoing monitoring of your power use and the PV panel production to further analyse and see if there are ways to shift load to make the most of the production curve of the solar system.

Flexible Finance

Own it—with or without finance, lease it, or just purchase the power on a supply plan. Whichever way you go, you’ll be saving a lot on power bills—making business more profitable!


How Commercial Solar is Financed





The choice is yours

Choose no upfront cost, or invest in maximised savings


Are you concerned that the capital invested on a solar installation would provide better returns if it was invested directly into your business? We can power your business with no upfront cost to you, or help you make the most of longer term savings. 

Three supply options for better capital investment


We offer three supply options to offset any burden of capital investment in different commercial situations. 

You can choose to finance your solar power system by: Purchase Outright, Lease, or PPA (Power Purchase Agreement). Pros and cons for each are below. And talk to us—we’ll work with you to establish which is going to be the best option for your business. 


Purchasing the system outright is the most straightforward option and yields the greatest potential gains. You pay upfront for the entire solar PV system. You arrange any finance, or Sunergy can provide finance.



  • Effectively have a free electricity supply once the system is paid off
  • Maximise return if not utilising a “middle man” financier
    Obtain the best pricing by paying upfront
  • The system is depreciable at circa 17% P.A. providing a good tax credit
  • Retain control of your system as the energy market, power prices and technology changes


  • Upfront capital expense
  • Finance costs if borrowing is required
  • Any opportunity cost of what else might be achieved if the capital was invested elsewhere


The Commercial Solar PV system is funded via our Lease Company and a contract is entered into in the same way you would lease a vehicle.

The term and monthly payments are negotiable as is the option to lease to buy, however, typically we work on a 10-year term with a further 1 x 10 year right of renewal, based on the system having an expected life expectancy exceeding 40 years. The customer pays for insurance and maintenance.



  • No upfront capital cost
  • The lease is a fixed cost every month, not affected by power production or usage
  • Lease payments are a deductible expense just like your monthly power bill
  • You effectively lock in or hedge the cost of a portion of your power for the term of the lease


  • You do not retain ownership of the asset
  • Overall savings will never equal that of an outright purchase
  • You are committed to the installed technology for the term of the lease

Power Purchase Agreement

A Power Purchase Agreement is where the commercial solar PV system is installed on a property or building but does not belong to the occupier/property owner, nor does the occupier/property owner have any control over it.

The power produced by the commercial solar system is sold to the occupier of the property, usually at a reduced rate compared to what their existing retailer is charging. There are several ways of invoicing each month, which are negotiable to suit, but essentially a PPA is a contract to purchase power from one supplier at an agreed rate, usually with price increases built in, for a long term.



  • No upfront capital cost
  • PPA power bill is a deductible expense just like your monthly power bill
  • You effectively lock in or hedge the cost of a portion of your power
  • The supplier bears maintenance and insurance costs


  • You are paying a premium to cover the cost of administering the PPA
  • Depending on the contract entered into, the price of power produced may go up
  • You are locked in regardless of what happens to the energy industry
  • You have no control over the asset
  • Regardless of what energy saving measures you initiate, you still pay per kWh of power produced/used so you will likely not maximise savings or self-generated consumption
  • What happens in the event the supplier closes down or liquidates?
