Let us design and build your solar net metering project!

What is Solar Net Metering?

Net metering allows an electricity user to install a solar PV facility onsite to generate electricity for internal use, with any excess going to the grid for a credit on future electricity bills. Net metering has been an option in Ontario since 2015 and is governed by Ontario Regulation (O. Reg. 541/05: Net Metering). However, only recently has the price of electricity and the cost of installing a solar PV facility made net metering with solar PV worth considering.

Some key business drivers that the Client should consider when evaluating whether net metering with solar PV makes sense now (2018) are:

  • the risk of electricity price increases;
  • time sensitivity for incentives; cost savings; and
  • the company’s reputation, which will benefit from generating “green” electricity.


Why Solar Net Metering, now?

The Ontario government has mandated that electrical providers, Local Distribution Companies (“LDC”) allow their customers to offset their electricity use by generating renewable energy. This is called Net-Metering. Solar prices have come down and electricity costs have risen. The point where net metering makes sense for your facility may already be here.  Let us tell you if that is the case. Even without a government incentive, there is a business case to be made for Solar Net Metering.  The chart below shows your cost of electricity for the next 30 years. You can determine your own opinion on what the prices of electricity are going to be in the future. The green light below is YOUR Solar system.

Is Net Metering with Solar PV right for your business?  We can tell you!

The Ontario government has mandated that electrical providers, Local Distribution Companies (“LDC”) allow their customers to offset their electricity use by generating renewable energy. This is called Net-Metering.

Solar prices have come down and electricity costs have risen. The point where net metering makes sense for your facility may already be here.  Let us tell you if that is the case.


Net metering (or net energy metering, NEM) allows consumers who generate some or all of their own electricity to use that electricity anytime, instead of when it is generated. This is particularly important with solar which is not dispatchable.   Net Metering is a program for electricity users with electrical generation capabilities to reduce their energy costs by sending surplus electricity back to the grid for credit against their bill. Cost reduction or avoidance is the main purpose of this program.

How does it work?

After you are connected to the grid through the distribution system, your local distribution company (“LDC”) will report what you have generated versus what you have taken from the grid. The result is the Net difference between these two amounts.  You will get a credit if you generate more power than you received from the grid. The credit can be carried forward for up to 12 months.

Eligibility criteria include, but are not limited to:

  • You must generate electricity primarily for your own use;
  • The electricity must be generated solely from a renewable resource (wind, water, solar energy or biomass); and
  • The maximum capacity of the generation facility can’t be more than 500 kilowatts.

To be eligible for Net Metering in Ontario the following conditions must be met:

  • The electricity must be consumed at the user facility;
  • The electricity generated is used at the customer's facility without reliance on any LDCs distribution system;
  • The nameplate capacity of the system cannot exceed 500 kW; and
  • The renewable energy generation system must utilize wind, solar, or bio-mass.

ORTECH offers a multi-tiered approach including:

An Initial Assessment and Feasibility Study will assist you in determining if Net Metering solution using Solar PV will benefit your bottom line.  This approach will simplify and de-mystify these up and coming technologies. ORTECH will break the process down into manageable steps.

Step 1: Initial Assessment: This assessment will determine if either a net metering or an energy storage solution will benefit your company. Net gain equates reducing the cost of energy.

Step 2: Feasibility Study:  This study will identify the high-level solution (type), benefits, costs and process to setup a net metering solution using Solar PV or an energy storage solution.

Step 3: Solution Development:  Identify options for the selected solution and develop an implementation plan for your facility.


There are some very compelling reasons why developers and investors should engage our team for renewable energy projects including working on over 855 solar projects in the last 4 years.  ORTECH's focus on renewable energy translates into superior quality, with industry leading experts who manage projects on time and on budget.

We have a different approach, we strive to help our clients, regardless if it means a project for us. We regularly help developers, equity investors and debt providers connect.  It's one thing most engineering firms do not do. We feel its helps the industry, and we do not charge a fee to make introductions.

ORTECH’s 40 years of experience in atmospheric sciences combined with state-of-the-art modelling and analysis provide dependable results

ORTECH can develop ground up solar resource assessment for input into the financial model. This is completed in conjunction with the project design in order to advise the optimum selection of equipment, fixed or tracking racking systems for example. The resource assessment will use site specific solar resource information triangulated from nearby reference stations.

ORTECH uses industry standard software packages to estimate the solar resource at the Project site, Meteonorm and PVSyst. These tools provide a high quality estimate of the potential output of a solar array. However, ORTECH's experience in the application of these tools including use of site specific weather data and appropriate degradation and loss factors is vital to ensure the software presents an accurate estimate of the potential energy generation from the solar farm.

An ORTECH solar resource assessment report typically includes:

  1. General Project Description;
  2. Predicted Monthly Energy Output,
  3. 30 Year Cumulative Energy Output,
  4. Interpolated Radiation and Temperature Data Set,
  5. Array Geometry,
  6. Inverter Output Distribution,
  7. Module Mismatch Losses,
  8. PVSYST Model Input / Output, and
  9. Results/Conclusions and Uncertainties.


ORTECH has worked extensively on solar farm economics, estimating costs and the performance of operating solar farms.  More importantly, we have experience in working closely with equity sponsors throughout the development process to revisit the financial model and input assumptions at every step of the development process.

The proforma financial models of solar projects are driven by several major factors:

  • Solar Resource and Power Price (i.e. Revenue)
  • Capital Cost and Operating Costs
  • Cost of Senior Debt

To better understand and manage these factors, ORTECH has developed a strong in-house solar resource assessment team that can optimize solar farm layout, explore the suitability of various solar panel models and is fully integrated with the financial modelling process. We also have developed a thorough understanding in estimating capital and operating costs through forecasting and backcasting work on past projects.
