Top Unexpected Factors to Consider Before Installing Solar Panels

Written by Posted On Friday, 29 November 2019 01:09

Installing Solar Panels

Solar panels are becoming increasingly popular with homeowners mainly due to rising electricity costs, but also as a more environmentally friendly form of electricity. A good solar panel installation in Perth helps to reduce power bills and produce a greener form of energy. A solar panel system may save up to 50% on energy costs while providing a sustainable system for generating power. However, there are many factors to take into consideration when considering solar panel installation in Perth.

How Do Solar Panels Work?

Solar panels are made up of small units called photovoltaic cells, which basically means converting sunlight into electricity. Many of these photovoltaic cells linked together make up a solar panel. Solar panels work by absorbing sunlight using the photovoltaic cells, which generates DC (direct current) electricity. The DC electricity is then converted into AC (alternating current) electricity using inverter technology. AC electricity is transferred to the electrical panel for use in the home.

Before going ahead with solar panels consider the following:

  • Your current electricity use
  • Choosing the right sized solar system for your needs
  • Check that the new solar systems meet Australian standards
  • Check the warranty
  • Understand all of the costs

Maintenance for a Solar Panel System

Regular maintenance is important for solar panel systems. This ensures that it continues to operate safely and efficiently. Over time dirt and dust can build up on solar panels, this compromises its performance and lowers its efficiency. As well as this, weather elements can also cause damage and deterioration to solar systems over time. Regular maintenance will ensure that the solar panel system continues to work at its peak while maximising savings on power bills.

Solar panel system maintenance should always be carried out by an accredited solar panel system installer, or licensed electrician. Regular maintenance can help to:

  • Keep panels clean and free from debris
  • Make sure solar panels are in good condition and secure
  • Keep vents clean and clear
  • Maintain parts
  • Check to wire
  • Conduct electrical checks
  • Check isolator switches

The Building’s Surroundings

It’s important to consider the surroundings of the building before installing solar panels. Particularly anything that blocks sunlight getting to the roof. If the roof is covered by shade for the majority of the day, throughout the year, this might not justify the costs of installing solar panels. Also, if there are a lot of large trees surrounding the home causing the roof to be in shade for the majority of the day, solar panels may not work as well as they could. It may help to prune trees and plan any future tree planting with the solar panels in mind.

The roof also needs to be in good shape structurally. It is easier to ensure the roof is in good condition before installing a solar panel system to avoid the cost of disconnecting and reinstalling the panels for roof renovations down the track.

Safety and Solar Panel Insolation Systems

Solar panel isolation systems add an extra level of protection by allowing the entire system to be shut off from a centralised location. Solar panels produce DC (direct current) electricity which is then converted into AC (alternating current) electricity to be used by appliances. In the majority of solar panel systems, DC electricity is converted into AC electricity through a centralised inverter which is located away from the actual panels. Cabling carries the DC electricity between the panels and the inverter.

DC electricity is significantly more dangerous than AC due to the high voltage and the fact that it is more prone to “arching”. In the event of a fire, emergency crews will immediately shut down the power from the grid to prevent the risk of electrocution, however a solar system will continue to produce power as long as it’s receiving sunlight. A solar panel isolation system allows the system to be shut off completely, stopping electricity from running through the system when needed.

The Cost of Solar Panels

The cost of installing a solar panel system will vary depending on the size of the system that is chosen. Prices of a solar system can vary $3,000 to $8,000 for a good quality 3kW system. The size of the solar system needed will depend on how much electricity is normally used and when it is used, roof space and budget.

How Many Solar Panels

The number of panels will depend on the system installed. However, the power output of the whole solar system is more important than the size and number of panels. The higher each panel’s nominal power rating is, the fewer panels will be needed, i.e. more power will be generated.

Solar Panel Efficiency

The efficiency of solar panels refers to the ratio between the amount of energy hitting the panels, to the amount of electricity generated by the system. The more efficient the solar panels, the more watts of electricity produced per square metre of the panel. So, it may be worth considering the smaller panels that have higher efficiency and take up less roof space, vs the cheaper, larger and less efficient panels.

Choosing between the smaller high-efficiency panels and the large less efficient panels may come down to budget and roof space. If roof space is limited, the smaller and more efficient panels may be a better option, however, they do tend to cost more.

There are many factors to consider when purchasing and installing a solar panel system. Some of the key points to remember when considering solar panel installation Perth include:

  • Maintaining the system
  • The surroundings, such as trees and other factors affecting sunlight
  • Installing a solar panel isolation system for safety
  • The costs
  • How much electricity is used/needed
  • How many solar panels are needed
  • The efficiency of the panels
  • Roof space
  • Warranty

Solar panels are a popular way for many Australians to save money on energy costs as well as take an eco-friendly approach to energy generation. Installation, maintenance, panel size and positioning are all important factors to consider when looking at solar panel installation Perth. However, installing a solar panel system may be well worth the cost in the long run when the electricity savings come in. Visit Mouritz for more information about solar panel installation Perth.
