Solar for Commercial and Industrial Applications

For commercial and industrial applications, we will look at the technical and economical benefit of installing solar. We will analyze the economic benefits of your solar installation from an investment point of view considering such as its return on investment.

Current trends shows that solar investment yield favorable return on investment due to decreasing prices of solar panels and inverters in the world market.

In addition, investing in solar shows you’re committed to helping the environment, a marketable addition to the business which will attract customers who like doing business with companies who are focused on sustainability and the environment.

Make the switch to solar!

With rising electricity prices and declining solar technology costs, business owners are finding it increasingly difficult to ignore the economic benefits of commercial solar power. Transitioning to solar can save money on energy today and hedge against rising utility rates tomorrow. However, before moving forward with solar, it is important to determine the total energy production and cost savings over the lifetime of your solar installation.

To have commercial solar power, the business owner must connect to the utility’s grid. Local electricity companies normally provide procedure in the interconnection process. If however you do not want to be involve in the process, we can assist you with this. This contract you sign should cover both technical and contractual issues with the interconnection. This safeguards both the person providing the commercial solar power and the utility company.

Grid Connection Studies for utility-scale solar farms

The five biggest challenges that utility-scale solar pose to the grid

1) Variability:Power plants that run on fuel (along with some hydro and geothermal plants) can be ramped up and down on command. But solar plants produce power only when the sun is there is sunshine. Grid operators do not control solar plants, they accommodate it, which requires some flexibility of the network.

2) Uncertainty: The output of solar plants cannot be predicted accurately in day-ahead and day-of forecasts, so grid operators have to keep excess reserve running just in case.

3) Location-specificity: Sun are stronger (and thus more economical) in some places than in others — and not always in places that have the necessary transmission infrastructure to get the power to where it’s needed.

4) Nonsynchronous generation: Conventional generators provide voltage support and frequency control to the grid. Solar generators can too, potentially, but it’s an additional capital investment.

5) Low capacity factor: Solar plants only run when sun cooperates. The average capacity factor — production relative to potential — for utility-scale solar PV was around 28 percent. The average capacity factor of nuclear power was 92 percent; those plants are almost always producing power. Because of the low capacity factor of solar, conventional plants are needed to take up the slack, but because of the high output of solar in peak hours, conventional plants sometimes don’t get to run as often as needed to recover costs.

There are solutions for integrating solar into the grid, they may include the following:

• Improved planning and coordination
• Flexible rules and markets
• Flexible demand and storage
• Flexible conventional generation
• Interconnected transmission networks

The need for grid connection study

High penetration of intermittent resources (greater than 20% of generation meeting load) affects the network in the following ways:

  • Thermal and contingency analysis
  • Short circuit
  • Transient and voltage stability
  • Electromagnetic transients
  • Protection
  • Power leveling and energy balancing
  • Power Quality


Typical Grid Connection or System Impact Study may contain:

  • Reactive Capability
  • Frequency Disturbance
  • Voltage Disturbance
  • Capacitive Reactive Current
  • Contingency Response
  • Frequency Control
  • Impact on Network
  • Steady State Studies
  • Voltage and Reactive Power Control
  • Active Power Control
  • Fault Current
