Can You DIY Solar System Yourself?


According to research, the average cost of going solar for homes (after accounting for the tax credit) is approximately $20,500 in 2023. Design and installation labour costs account for about 10% of the entire bill; this is what a DIY solar system will save you, as you will still have to purchase the equipment and components yourself. Regardless, it's tempting to consider DIY solar system installation to save money and have complete control over your home renewable energy project.


What is a DIY Solar System?


A DIY solar system is one that a homeowner designs, installs, and maintains themselves rather than hiring a professional installer. This do-it-yourself approach to solar energy is popular due to its low cost, customizability, and increased interest in sustainable living. In this guide, we'll look at the components of a DIY solar system, such as panels, batteries, and inverters, and the fundamentals of using solar energy at home.

A DIY solar system is a complete, unified set of components that form a functional solar panel system. While each DIY solar system will be unique, it should include everything you need to gather, store, convert, and transport the sun's energy into useful power for your home or RV. All DIY solar system components may often be purchased separately and combined into a solar panel system. A solar system, on the other hand, is designed with advanced preparation. The user does not need to determine whether the components are compatible; assembly is seamless, and compatibility is ensured.

What Are The Components of A DIY Solar System?


Although some solar kits may have more items than those listed here, any solar kit worth your money will include the following:

what is a solar system

Solar Panels: Solar panels, commonly known as PV panels, are the essential components of a solar system. The photovoltaic effect allows them to turn sunlight into power. Based on efficiency, available space, and affordability, DIY enthusiasts can select from various solar panels, including monocrystalline, polycrystalline, and thin-film panels.

Batteries: Solar batteries store the electricity produced by solar panels for later use, mainly when there is no sunlight. Lead-acid, lithium-ion, and salt-water batteries are some of the most common solar batteries. DIY solar system designers must consider battery storage capacity, voltage, and longevity to meet their energy requirements.

Inverter & Charge Controller: Inverters convert the DC generated by solar panels into AC, which most household appliances use. Several types of inverters include string inverters, microinverters, and power optimisers. DIY solar system enthusiasts should select an inverter that corresponds to the size and layout of their solar panel system. The charge controller keeps the battery from overcharging by controlling the flow of electricity between the solar panels and the battery. The charge controller is an optional component, much like the battery bank.

Cables & Wires: All DIY solar systems contain all the cords required to connect the components. Larger solar panel kits for residences will include gear to put the panels on the roof or the ground.

DIY solar systems allow individuals to control their energy generation, increasing sustainability and lowering reliance on traditional energy sources. Understanding solar system fundamentals and adhering to installation and maintenance best practices are critical to a successful, efficient DIY solar project.


What Are The Pros and Cons of A DIY Solar System?


DIY solar systems can be a good choice for moving off the grid and some small-scale household applications. However, hiring a professional installer to power your complete home may be advisable.

Most home DIY all-in-one solar systems (including solar batteries and inverters) are intended for off-grid use. Thus, you cannot utilise them while remaining connected to your utility. If you're an average homeowner, going off-grid is generally not in your best interests; connection to utility-generated electricity is required if your solar array needs to create more electricity to suit your needs at all times of the day and year.

On the other hand, home solar systems can be an effective alternative if you intend to power only some of your home. RVs, boats, and the increasingly popular tiny houses are all great places to experiment with DIY solar because they are already off-grid and transportable. Storage kits, including battery banks and systems, are also an excellent backup alternative in a power outage.

On a related note, DIY solar projects can be helpful if you have a vast property and want to power a remote place, such as a barn or tool shed, or if you're going to add outdoor lights quickly. In those circumstances, your electricity demands will be low, making purchasing and installing a small home solar kit possible.

Depending on local zoning restrictions, DIY installation may be unlawful where you reside.


How to DIY Solar System?


The popularity of DIY solar panel systems has grown in recent years, particularly in areas with abundant sunshine, such as Australia. Using solar energy at home promotes environmental sustainability and lowers electricity expenses. However, establishing a DIY solar system involves meticulous planning and consideration of numerous elements.  

how to diy solar system

Step 1: Size Your System via Power Consumption


When designing a solar power system, you must first determine the size of the system required. This size is primarily determined by the electricity needed to power all appliances. Conduct a thorough energy audit to assess your energy use to size your system correctly. A straightforward approach is to look at your previous electricity bills and compute your average daily electricity consumption to select the entire number of watts needed for your solar system.

Begin by identifying the equipment you intend to power with your solar generator. Take note of each gadget's wattage, usually indicated on the item or in the instructions. Add these wattages together to calculate the total wattage. Determine how many hours every day each gadget generally operates. To calculate the watt-hours (Wh) required for each gadget, multiply its wattage by the number of hours used. Add the Watt-hours necessary for all devices to calculate overall daily energy consumption.

Step 2: Obtain Necessary Permits in Your Region


You'll need to secure the proper permits, as different regions have different regulations for solar installations, so contact your local building department to learn more about the procedure and submit the required documentation.

Most property owners require many permits to construct and connect their solar panel systems to the grid (including DIY solar projects). Exceptions are rare. One example is an off-grid solar energy installation. However, it is inconclusive; some states and towns may require you to obtain specific licences even if you are going off-grid. Solar permit requirements vary by region, municipal code regulations, and the size/type of your solar installation. The most typically required solar permits are:

  • An electrical permit
  • An interconnection permit to connect to the grid
  • A building permit
  • A solar photovoltaic (PV) permit

Your local building authority and utility company will need information about your system to obtain permits. Your local utility company issues you the connection permit. During the application review process, your solar system's compatibility with the grid is routinely verified, as is the safety and stability of your house's electrical network.

Step 3: Purchase The Installation Tools & Materials


Solar panels, batteries, charge controllers, solar power inverters, and various installation tools are required for any solar system project. You may compare panel, battery, and inverter products based on efficiency, warranty, and other specifications.
