By August 13, 2021August 26th, 2021No Comments

The decision to purchase a solar power system quickly turns into an intimidating labyrinth of complex considerations for most home or business owners.

There are a myriad of factors to keep in mind and ignoring any one of them can result in short or long term loss. Often, subtle aspects of my home or neighborhood can end up causing trouble, while in other cases, glaring issues are overlooked or given the workaround which only leads to an unsatisfactory experience.

At bidmysolar™, we can help you navigate through these complexities and get you a quality solar outcome that works for you saving you hours that you will need to spend on research. Get in touch with us today and experience the difference.

However, if you would rather do this research yourself, we’ve put together a checklist with a list of questions to ask yourself, and your chosen solar installer.

Is My House Solar Compatible

  • Can my roof accommodate solar panels?
  • What is my roof’s angle and what direction is it facing? (For more on this, refer to our article on how roof orientation affects solar panels.)
  • Are there trees or buildings around that cast a shadow on my roof?
  • How much sunlight falls on my roof average?
  • Is my area prone to storms/hurricanes/bushfires?
  • Does my house/commercial space have a one, two or three phase electrical system?

Calculating Energy Requirements

  • How many KWh of electricity does my house/commercial space use every day? You can use this calculator to get the figure.
  • What is my average monthly electricity bill?
  • How much does the price of electricity hike year on year where I live?
  • What time of day does my home/commercial space use the most electricity?
  • Is there any wasteful energy usage that I can cut out? If yes, then how much can I save up on bills by optimizing my energy usage?

Selecting a Solar Installer

  • Does the installer have a web presence? Do they have a website, social media presence?
  • Is the installer CEC accredited? Use this page for a list of CEC accredited installers throughout Australia.
  • How many years has the installer been in business?

  • Do they offer details of solar panels, inverters and batteries on their website? Are the products from reputed manufacturers?
