5 Installation Tips to Ensure a Better Solar Panel System

Posted By info@hybridenergyconcepts.com

Finding the right solar panel system for your home depends on many factors. If you plan to invest in one, the last thing you want is to make the wrong choices. It always pays to know the essential things before making decisions, especially for homeowners with little to no technical background. Make sure to arm yourself with the right knowledge so that your purchase would be worthwhile.

If you plan to install solar panels in your residence, here are the things you need to keep in mind: 

When Choosing the Panels

  • On the Panel's Degradation Rate

Panel options vary depending on their degradation rate, and it usually reflects in the cost. The lower the degradation rate, the higher the value. Choosing more expensive ones might not make a difference for people who do not plan to stay long in their residence, especially compared to a conventional panel. 

However, if you plan to stay in your house for a long time—let us say ten years or more—investing in solar panels with a low degradation rate would be the more cost-efficient option. 

The degradation value for a conventional panel and the panels with a low degradation rate is usually the same in the first five to ten years. The difference would only be noticeable after years of its service. For example, on its 25th year of service, the difference in degradation value between the two would reach around $4200. That is how much you would save if you opt for solar panels with low degradation.

Investing in quality panels could also be beneficial in other ways. Companies that provide a low degradation solar panel also ensure that their product has the following advantages: longer product warranty, improved performance in high temperatures and low light, stability, and longevity.

When Preparing Your House - Solar Panel System

On Your Roof Design

There are two things you can do when you plan to set up solar panels in your house. Solar panels can be adjusted based on your house's roof design, or you can modify your roof to meet the most optimal location for your solar panels. 

If you are still in the process of building your house and plan to place solar panels, eventually, you have the advantage. Here are the things you need to remember when designing it:

  • Understand what parts of the roof would experience shading and consider this in your solar panel location design.
  • Aim for a northern orientation for your solar panels.
  • Avoid placing ventilation pipes, skylights, and other accessories in locations you plan to put the panels.
  • Keep the satellite dishes, antennas, and other similar roof features opposite the solar panels' directions. 

On the Type of Power Supply

Houses in Australia can be categorised depending on their power connection. The majority of them have single-phase power, but those with bigger houses usually have three-phase power. Homes belonging to the latter category often have multiple overhead cables on their poles. It means that the electricity in their place is distributed in three phases. 

Houses with single-phase power have a standard voltage power of 230V. Homes with three-phase power enjoy both the 230V and around 400V power supply from the grid. The higher voltage ensures enough energy is delivered to the house. 

Since you plan on setting up solar panels in your home, it would be best if you acquire a three-phase power system, regardless of your home size. Here are some advantages to doing so:

  • The higher your house's voltage power, the more power (kW) your solar panels can export to the grid. 
  • The three-phase power can give your home a more stable voltage. With a stable grid voltage, you can use more appliances efficiently.
  • A stable voltage can also allow your inverter to produce more power. 

When Installing the Panels

On Hiding the Wires

If you are keen about how your solar panels' wirings should look, make sure to give your installer a heads up about it. The wirings of solar panels are not like other electric wirings. 

Solar panel wirings are almost live every time. There are only two scenarios when they are not:

  1. When you turn the switch off
  2. When the sun is down

Their capacity can reach up to 600V DC. Therefore, they cannot be attached to any circuit breaker or safety switch. They require other means of protection to avoid electrical damage. Because of this, you cannot simply request to hide them underneath your panel's internal walls. Installers need to adhere to regulations on how and where they can place the cables. 

Please keep in mind that only experts familiar with protection methods and other requirements should perform any cable-related jobs on solar panels. Otherwise, other electricians (without proper licenses, documentation, or experience) might use the incorrect cables and other installation components. All these are important to ensure that the installation process is compliant with local rules and regulations.

On Solar Inverter Location

Deciding where to put your solar inverter also plays a vital role in ensuring your solar panels' performance. Not every supplier will tell you that keeping your inverter near your switchboard can minimise cost and voltage rise, making it a better overall decision. 

Again, this instruction would affect the electric wiring setup in your house, so make sure you inform your installer about this request during the planning stage. 

In case you do not know, you can also use your inverter to monitor your solar system. You have two options for this:

  1. Monitoring via WiFi
  2. Monitoring via LAN cable connection

The second option is always the most reliable one. If you prefer it, you need to prepare a LAN cable ahead so the installer can connect the system to your home network during the installation process. 

Conclusion

Learning about the dos and don'ts can be your first step towards understanding solar panel technology better. But learning about the essential steps before building your house or arranging the solar panels can help give you a long-lasting and productive system. Installing solar panels the right way can ensure the efficiency of your panels. Keep these points in mind before you book a service or start building.
