What are the Pros and Cons of DIY Solar?

Learning how to install solar panels requires extensive research and plenty of hard work. We know it’s not for everyone, so we want to highlight the pros and cons of the DIY Solar approach and decide for yourself.

Some DIY solar panels pros and cons to consider:


  • Save on most labor costs (which can account for over 50% of a traditional solar panel installation cost). For an average-sized system, you could pocket more than $12,000 by installing it yourself
  • Design your solar electric system from scratch to suit your specific needs. Choose from a more extensive selection of brands and only buy as much as you need (no “one-size-fits-all” packages).
  • Fewer unexpected costs and surprises along the way. You’re in control of everything.


  • It’s hard work. You have to put in a lot of sweat equity to make your DIY solar dreams a reality. Finishing your build is immensely rewarding, but some homeowners may not have the time to commit to a project like this.
  • Some local building departments may not allow DIY solar projects. Especially for off-grid systems, certain jurisdictions require solar systems to be built by a certified professional.
  • Professionals typically offer a 5-10 year labor warranty when they install a system. If you go DIY, you’re solely accountable for the quality of your work.
  • Unless your a licensed installer you could be breaking the law

Assuming you haven’t done the ‘Illegal’ solar panel install yet…

If you’re installing solar panels for the first time and want advice, ask your local electrician, and they’ll point you in the right direction.

However, if you are not comfortable with them, you can go to a lawyer specialising in solar panel installations.

If you are not comfortable with them either, you can go to a company that will act as your proxy when dealing with legal advice and fines.

However, this can become expensive, and it’s not always easy to find a proxy. Make sure that you find out the laws about installing solar panels in Australia. It could be illegal, and ignorance is the only defence that works every time.

Ok, so are planning on installing a solar panel system DIY anyway?

If you are planning to install a solar panel system on your home, make a cost comparison to make sure you are getting the best deal. If you can get more solar panels for your money, then you will end up saving a lot of money over time.

1. Solar panel system design and size

The right solar panel system choice is a crucial one for your home, and you will be glad that you have researched it. Many people do not have a clue what to look out for when they are buying one, which is a big mistake. It doesn’t matter if you buy one from a retail store or a company online.

There are several different things that you need to consider when choosing the right solar panel system choice.

Solar panel kits

Solar panel kits are made up of a wide variety of components that are all used to make up the solar panels. When purchasing these solar panel kits online, you will find that these kits are made up of a wide variety of components, and some kits may even be constructed from many different components.

With the help of the internet and a useful guide on DIY solar panel kits, even beginners can do this. The guides available online can give an excellent explanation to people, explaining the technicalities of the DIY solar panel. The guides are well written, detailed, and easy to understand.

If you want to assemble your solar panel system, there are several ways that you can go about it. One of the best ways is to buy from China. However, you will want to be careful because it is a very competitive market, and there are some horrible people out there that will take advantage of your ignorance and start ripping you off. It is best to do your research and find out what you are getting yourself into before you do any of this.

The best place to purchase solar panels, solar mounts, and DIY solar panel kits online is online, as many different companies can provide you with all the information you need.

The other way is to go to the government-owned outlet in China and buy directly from them. It might save you a lot of money in the end.


2. Purchase solar equipment

The first thing you must-do if you are planning to purchase solar equipment is to have it checked by a professional before you spend your money on it. You must get your system checked by someone who has a good understanding of solar cells and how they function, so you know you are doing your part in saving the environment.

If you don’t have someone to check it, you might make some costly mistakes that could even get you in serious trouble with the authorities.

If you haven’t already done so, you should also get an inverter, a rack, and an inverter tower. All three are extremely important, and all three are very important to the functioning of your solar system. The racking is used to put all the solar cells on top of one another, and the inverters are used to regulate the electricity. Having all of these things checked is the best way to ensure your solar equipment is doing its job right. If it is not performing the way it should be, you should have all three checked and replaced before you go out and purchase more solar panels.

3. Solar Racking System

If you decide to install the racking on your own, you will need to determine if you are using a prefabricated system or a ready to assemble a racking system. The ready to assemble system is more comfortable to install; all you will need to do is the drilling and routing the cables for the solar power system.


4. Solar Mount System

Roof-mounted systems are a great choice – there is a wide range of components and systems out there to custom-fit almost any module configuration to almost any roof – flat or pitched, building heights of up to 200m.

The best way to connect the solar panels to your racking can be used to mount the solar panels to be positioned in the most convenient location for you to begin with.

Ideally, a fixed, roof-mounted solar energy system should be at an angle equal to the latitude of the location where it is installed. However, pitch angles between 30 and 45 degrees will work well in most situations.

5. Install a solar inverter

Once the solar panels are securely mounted, it’s time to connect it to your electrical supply.

Installing solar inverters is something many folks are hesitant to do, especially if you don’t have a lot of electrical experience. If you have a sound understanding of electrical wiring, you should be able to wire a solar inverter correctly. A permit may be needed.

You can install a solar inverter yourself and save quite a bit of money. I will give you a couple of tips and tricks to help you along your way.

The first thing you should do before installing a solar inverter on your own is to find a quality manual that explains the process in layman’s terms. The manual should be easy to understand and easy to follow. There are several great manuals available online.

Once you find the manual, the next step is to find a qualified electrician with the qualifications you need to install a solar system for your home or business. Once you have your electrician, you will need to schedule an appointment to help you install the solar inverter, and you will want to bring along the correct tools that you will need.

DIY Solar Panels Installation FAQ’s

Is it cheaper to build or buy solar panels?

The question is often asked as to whether it is cheaper to build or buy solar panels. The short answer to that question is that it depends. If you are building your solar panels, you will save more money, but they will also be much more challenging to build than a kit.

The cost to purchase a solar panel kit online in 2020 is approximately $2.80 per watt. This figure is based on average kit prices. Be warned though some of the kits use very low-quality components.


How do you ground a solar panel?

If you’re looking for ways to build your solar power system, one of the most important questions you have to ask yourself is, how do you ground a solar panel? You don’t want to have a bad experience when you’re trying to wire up the solar panel.

All exposed metal parts (e.g., racking, conduit, enclosures) of PV systems (regardless of voltage) must also be grounded (690.43). This equipment ground is accomplished through the electrical interconnection (or bonding) of all those metal parts with the earth.

When installing a solar photovoltaic system (PV), all the equipment must be grounded correctly. Failure to ground the entire system to include all the individual pieces can be devastating, especially in an area that experiences lightning regularly.



Key takeaways concerning ‘Do it Yourself’ solar panel installations.

  • Installing a DIY or solar panel kit system is technically possible and maybe cheaper than using an accredited solar installer.
  • Going with a DIY setup requires much more work on the homeowner’s end.
  • It’s probably illegal in most parts of Australia.
