Key Components of a Solar System
Before we get to the solar panel installation process, let’s go over the key components of a solar system:
- Solar panels: These are the main components of the system—they capture sunlight and convert it into electricity. Therefore, for the system to be as efficient as possible, the panels need to be angled correctly.
- Inverter: This part changes the direct current power from the panels into alternating current power used by most home appliances. The inverter should either be near the panels or in a cool and dry space for optimal performance.
- Solar battery: A battery stores extra solar power and saves it for nighttime use or cloudy days. Its proper installation prevents damage from overheating or overcharging.
- Charge controller: This element regulates the power going to and from the battery, thus preventing overcharging. It needs to be correctly installed to help protect the battery and prolong its lifespan.
- Mounting system: This structure holds the solar panels in place on your roof. It must be securely installed to withstand different weather conditions and prevent panel movement.
- Wiring and electrical components: These connect all components into a solar system. They have to be the right type and size and installed properly to avoid electrical hazards.
Preparation Before Installing Solar Panels: 3 Key Steps
Preparation before installing solar panels involves assessing your needs, evaluating the location, and collecting the necessary permits and paperwork.
Let’s explore these stages in more detail:
#1. Assess Your Needs
If you’ve decided to switch to solar power, first, you need to figure out how much energy your home uses. You can do this by checking your electricity bills to see your average monthly consumption in kilowatt-hours (kWh).
Additionally, you should decide whether you want to power your entire home with solar or just use it to cover some of your electricity needs.
That said, you ought to look beyond your current needs—do you plan on buying more appliances or an electric car? If so, your energy demand will grow.
#2. Evaluate the Location
Choosing the place for your solar panels is critical for their efficiency. For example, roof-mounted solar panels are generally a good choice for homes facing south (in the Northern Hemisphere). Still, if your roof has shade from trees, chimneys, or buildings, you might want to opt for a ground-mounted solar system instead.
If you decide to install solar panels on the roof, you need to check if it’s strong enough to handle the system. If not, you should think about reinforcing your roof.
#3. Permits and Paperwork
Going solar usually requires permits and approvals to comply with local laws. With this in mind, you need to look into the rules of connecting to the grid in your area and check building codes beforehand.
This is especially important if you plan to install solar panels yourself. On the other hand, if you go with a professional installer, they’ll likely handle the paperwork for you. Either way, having the correct permits ensures your system is safe and in accordance with legal standards. On top of that, it protects you from any penalties or fines down the line.
How to Install Solar Panels: Step-by-Step Process
Now that we’ve covered the preparation stage, let’s see how to install solar panels from start to finish.
In general, there are nine solar panel installation steps, beginning with installation site inspection and ending with monitoring and maintaining the system.
Let’s explore them more closely:
#1. Installation Site Inspection
As previously mentioned, you need to choose an adequate location for your solar panels based on sun exposure. However, that’s not the only requirement—the strength of the foundation plays an important role as well.
Namely, you must check whether the roof or ground can support the weight of solar panels and mounting equipment. Look for structural damage, signs of wear and tear, and any weak spots that may need repairs. In addition, you need to have your electrical system inspected to confirm it can handle the solar setup.
#2. Set Up the Scaffolding
If you decide to place your solar panels on the roof, you need to set up the scaffolding to have a safe platform for working up there. This structure allows installers to move securely and access tools and equipment at height without risking falls.
By extension, scaffolding also protects the roof—with it, workers don’t have to step directly on fragile areas, which prevents unnecessary strain on the roof.
#3. Set Up the Mounting System
After setting up the scaffolding comes the installation of the first component of the solar system—the mounting equipment. Its purpose is to position the panels in a way that maximizes their exposure to direct sunlight.
This step also involves weatherproofing the system to protect it from leaks and damage. All in all, mounting your solar panels increases their efficiency and durability, ensuring you get your money’s worth in the long run.
#4. Position the Panels
When the mounting system is set up, panels are placed on it at just the right angle to soak up as much sunlight as possible throughout the day. Installers do this by tweaking the tilt and spacing to avoid any shading from nearby trees or buildings.
Once the panels are perfectly aligned, they’re securely fastened to the mounting system so that they stay in place no matter the weather conditions.
#5. Install the Solar Inverter
The correct solar inverter setup is key to proper operation—not getting this part right can cause issues for your entire system. The inverter is usually placed close to the panels or in a shaded spot to keep it from overheating and wired up to handle the flow of electricity.
During this stage, you need to make sure all connections are tight and safe. This is because loose or incorrect wiring can lead to power loss, damage to this and other components, and even fire hazards.
#6. Wire the Solar Panels
Once both the panels and the inverter are in place, it’s time to connect them to each other with electrical wiring to create a complete circuit. You should make sure to use high-quality wires so that the electricity flows safely and efficiently. This will cut down on power loss and, by extension, energy costs, which is the whole point of going solar.
#7. Connect the Solar Inverter to the Grid
Now that the inverter is in place and connected to the panels, you need to link it to your home’s electrical system and, if applicable, to the power grid. This way, you’ll be able to use the solar power directly and send any extra electricity back to the grid.
If you’re using an off-grid solar system, the inverter connects to the battery instead. In this case, you may consider getting a solar generator as a backup power source to store energy for later use.
#8. Test the Solar Power System
Once all components are installed, it’s time to test the system. In this phase, the installer checks if the panels are generating power properly, the inverter is working well, and everything is securely connected.
This step is essential for spotting any issues before they become major problems.
How Long Does It Take to Install Solar Panels, and Should You Do It Yourself?
Depending on the size of the system and the complexity of the setup, it can take about one to three days to install solar panels. For a typical home system, the installation is usually done in a day. However, you should factor in the preparation stage—this can last longer due to permits and inspections.
That said, you shouldn’t install solar panels yourself, as simple as the process may seem. The reason is that setting up this system calls for electrical knowledge, proper wiring, and safety measures that can be tricky if you’re inexperienced.
This is why you should leave it to professionals, such as Portable Sun, as we’ll ensure everything is done correctly, safely, and up to code. Plus, we can help with any paperwork or permits you may need.
