Solar PV Install

Solar PV Install

Northstar provides the design of a system to suit the family needs, whether this is a PV system alone or with additional storage to make the most of the energy our star delivers every day. Northstar also provides EV charging stations so the family can run their electric car by using the everyday power from our Sun.

You can cut your greenhouse gas emissions and energy bills for your home or business by using a free and renewable energy source, solar energy. How solar PV cells work – Photovoltaic (PV) cells convert sunlight into electricity. The amount of power a solar PV system generates depends on the intensity of the sunlight. It still produces electricity even on cloudy days.

 

PV systems include:

  • PV panels, cables, and mounting or fixing hardware
  • an inverter and controller
  • batteries, back-up generators, and other components for off-grid situations
  • special electricity meters (for grid-connected systems)
 

Here are a few key points to consider:

1. Your location and sunshine hours can determine how much electricity you generate:

  • This solar generation is defined in kilowatt-hours (kWh). Every kWh you generate and use is one less you have to buy from the grid
  • The price paid for electricity from the grid varies from region to region. The more you spend (c/kWh or c/unit), the more you will save per kWh you produce from solar

2. The electricity produced by solar can be used in any of the following three ways:

  • Used by household appliances and heating water – this is called self-consumption. The more solar electricity you consume, the better you return
  • Sent to a battery bank or used to charge an Electric Vehicle (EV)
  • Sent or exported to the grid, where the solar electricity is purchased for a low price by some retailers. Exporting electricity should be kept to a minimum for the best financial outcome
  • And or all of these can be applied depending on your needs

3. The size of the solar system (measured in kWh) you install should be determined by two factors:

  • Size of your household/premises
  • Percentage of electricity generated that you can consume 

4. Whether you are home or not, there are many ways you can maximise self-consumption of electricity you generate during the day:

  • Change the time when you use power-hungry appliances 
  • Use simple timers placed on appliances set to operate during the day when solar is generating
  • Use automated internet-enabled in-home technologies with smartphone app access
  • Consider a Home Energy Management System (HEMS) that allows automatic operation of specific appliances, can divert solar electricity to heat your water into your home batteries or an electric vehicle and minimise the electricity you export to the grid
