System Design

Understanding the value of a solar system means understanding the value of energy.

  • A solar system is a long term investment because it will generate a great deal of energy over a long period of time.
  • The amount of energy generated won't always stay the same and it is unlikely that the value of that energy will stay the same either.
  • As the years roll on your solar system's total production potential will degrade little by little but the value of that energy is more than likely to continue to increase.

Consumption Offset


Monthly Production and Consumption

Solar systems in Nova Scotia produce much more energy in the summer than they do in the winter.

  1. Β If you generate more electricity than you can use in a billing period, surplus kilowatt-hours (kWh) will be β€œbanked” and applied to your next bill to offset any electricity drawn from the grid until the end of the year.Β 
  2. If you end the year with excess generation remaining, NS Power would apply this to any billed consumption within the same calendar year up to a maximum of your total billed energy.Β 

This means you can achieve a "Net-Zero" home in Nova Scotia by generating as much energy as you use in a calendar year, regardless of when it is generated or when it is used.
Consumption Offset:
Year Month Total Production Total Purchase End kWh Credit End kWh Credit Value

Value over Time: $122,639.34 in 30 years

Two things happen when energy rates increase for homeowners with a PV system:

  • Payback period shortens,
  • Return on investment increases,

Residential energy rates have increased in Nova Scotia by an average of 3.3% for the last 10 years and Nova Scotia Power will certainly continue this trend.

Solar panels may be the stars of the show, but these 35 inverters are the real brains behind the operation πŸ§ πŸ”Œ

Microinverters handle tasks like:

  • monitoring,Β 
  • performance verification,
  • system maintenance and ensuring the longevity of your solar system.Β 

So, while your panels are soaking up the rays, your microinverters are working hard to keep your solar system at peak performance.

At The Sun Box we choose enphase because they are without a doubt the more innovative of all the inverter technologies.

  • Class II double-insulated enclosure
  • More than one million cumulative hours of testing
  • Optimized for the latest high-powered PV modules
  • Remote automatic updates for the latest grid requirements

35 inverters gives you a total of 10.5 kW AC

Will a grid-tied solar system power my home during a power outage?

Tom Rendle

Posted about 2 months ago

1 minute read

A Solar PV system is capable of producing more power than your property uses in a day, this excess goes back to the grid. During a power outage you cannot export power to the grid as it could injure line-workers so all grid-tied Solar PV systems are designed and required to shut down automatically as soon as they stop detecting the grid. This is called "anti-islanding". Additional components can be installed that allow a part or all of a grid-tied solar PV system to operate during an outage but this typically requires a significant investment and is not trivial.

*All calculations are an average based on the power your panels are expected to generate, and your usage average last year, not the exact new bill. Your new bill will still depend on how much energy you use in the future. Incentives are subject to change. The actual amount can be higher or lower than what is quoted, and may not stay at a fixed rate over time.
