How to avoid dodgy solar installers

Fast read

When considering solar energy options, it is important to ask the installer a variety of questions to ensure you are getting a high-quality and reliable system.

Some key questions to ask include: how long the company has been in the solar industry, what accreditations they have, whether it will assist in the system's connection to the grid, what after-sales service they offer, what finance options are available, whether the recommended products are in line with CEC standards, what the available feed-in tariff is in your area, what documentation will be provided after installation, where the company is located, and whether they have a good reputation.

Asking these questions can help you make an informed decision and ensure that you get the best solar system for your needs.

Questions to ask the installer to avoid dodgy solar installers

1. How long have you been in the solar industry?

This will allow you to get an understanding of their experience. A true industry veteran has survived the ups and downs and is likelier to stick around. Dodgy solar installers who have recently appeared in the solar industry or have only been active for a year or two should raise suspicions about its long-term commitment.

2. What accreditations do you have, and will you install the system?

Make sure that the installer that will be working on your system is CEC accredited. This is because, otherwise, one would claim the rebate fraudulently. The rebate is only supposed to be paid to installations by CEC-accredited installers.

3. Will they be able to assist in your system’s connection to the grid?

Most solar installers should provide this if the installer refuses to answer or says no. This should be seen as a red flag. You want the install company to manage the grid connection part. This will allow you to avoid spending time on the phone and dealing with third parties.

4. What after-sales service do they offer?

This is one of the most critical components of an installation that is often overlooked. As solar and batteries are long-term investments, having a company that can help maintain the system on short notice for many years is crucial.

5. What finance options do they offer?

This will allow you to get an insight into whether or not you will have to pay for the whole system upfront. For example, a finance option might allow you to pay for part of the system and finance the second part—that way, you can choose the higher-quality option.

6. Are all their recommended products in line with CEC standards?

Some dodgy solar quotes give you good gear but have a clause in the contract that they can substitute the system components for “equal quality” ones.

7. What is the available feed-in tariff in this area?

You might need to consider changing energy retailers if your current provider does not offer the most competitive rates. Your installer, which deals with this issue daily, should be able to recommend the best electricity plans in your area.

8. What documentation will be received after the installation?

Usually, companies will supply a handover kit as part of the handover. This is also crucial as it will determine how well-educated you are and how much understanding you will be given about your system, which is particularly important when there’s a problem.

9. Where are they located?

This links to the availability of after-sales service. If they are local, they will be much more likely to come and inspect your property pre and post-installation of solar panels. If their head office is hundreds of km away, they must engage a sub-contractor, which will always take some time.

10. Do they have any case studies or past customers?

This is to see how they have worked in the past so that you get an idea of the installation quality and customer service they provide.

Questions to ask yourself

11. How much electricity do we use?

This will allow you to do some prior research via past energy bills and understand the home solar system size you will be working with. Then, of course, there are other variables to consider. However, this is the first basic required knowledge.

12. What is our budget?

This is an important question as solar and battery systems can come in various price points. However, we recommend never going with extremely cheap solar, as it always will disappoint after a relatively short time.

13. What is the expected time frame for significant returns?

As this is a long-term investment, understanding when you should expect to make returns beyond the purchase price, e.g. after five years, is essential. However, you won’t need to be stressed when you don’t see immediate positive returns and will have some realistic expectations.

14. Will the company quoting my solar system do the installation?

This is important as many dodgy solar panel installers use third parties to install their work and then want to see these third parties be responsible if there is an issue. You want the company you paid to be responsible for the ongoing support. So even if they sub-contract part of the work, they are still your party to make after-sales inquiries.

15. Do I know how the warranty claims are handled?

Warranty claims can consume a lot of time, so ensure you grasp the basic procedures. This preparation ensures that if the day comes when you need to make a claim, you won’t feel stressed.

Questions specific to the solar system to avoid dodgy solar installers

16. What system size do they recommend?

This will allow you to explore how much you should expect to pay and how much roof space you should expect to be occupied. You can also try our solar output calculator to see how much electricity you can expect to generate year-round.

17. What is the expected lifespan of the proposed solar & battery system?

Asking this question is crucial to grasp when substantial gains will occur and their duration.

18. Will shading be an issue for my solar system?

This will determine what angle your system faces, what products will be used, and how energy efficient the panels will be. Also, this will mean you will not receive maximum solar power output for some of the year.

19. What direction will the panels face, and will this affect their production?

It can also impact your system’s ROI because panel direction should align with your consumption pattern. For instance, heavy afternoon air conditioning use benefits from solar panels facing North-West or West.

20. What product models and brands will be used for the system?

Researching the products recommended allows you to assess their quality and determine if they are dodgy solar installers based on their suggestions.

21. Under what specific conditions will the warranty be voided?

This is important as it will ensure you don’t do something such as move the panels yourself. This will void your warranty, meaning your products are on their own.

22. Will you be able to add extra additional panels or solar battery storage in the future?

As solar becomes increasingly popular and cheaper, you may want to add extra panels in the future or store your excess energy instead of sending it to the grid. So ask this question to know if it is possible with your soon-to-be-installed solar solution.

23. How do we monitor the system’s performance?

Most new inverters do have this monitor technology. However, ensure you know if what you are installing does, as it helps understand your solar returns.

Affordable third-party monitor solutions such as Solar Analytics Integrated + are also available. They offer a wide range of benefits for al ow annual subscription rate.

25. Where do we install the inverter and battery?

Ensure you have the appropriate location for these system components and that they visually blend into your home. They are also better installed away from heat and direct sunshine exposure.

Suppose you are at the stage where you are contacting installers. Include these questions in your conversations, as the answers will help you determine a solid supplier.
