Understanding the Soil Resistivity Test: Ensuring Safety from the Ground Up

When planning or optimising an earthing system for a project, one crucial step is conducting a soil resistivity test. This test measures how well the soil can conduct electricity, which helps determine if it’s suitable for the earthing system. Additionally, it also helps optimise the design of existing earthing systems to meet the specific needs of a project. Let’s explore the significance of conducting a soil resistivity test:

Preventing Electrical Hazards

The test helps identify and mitigate potential electrical hazards, such as electric shocks and fires. By understanding the soil’s resistivity, we can then design an earthing system that effectively dissipates fault currents, preventing dangerous voltage buildup.

 

Improving Safety

A well-designed earthing system protects both people and equipment. By ensuring that the earthing system works efficiently, we can safeguard individuals working on-site and the electrical equipment they use.

 

Planning and Design

Once we have acquired the soil resistivity value, we can better plan the earthing system. This includes selecting the right materials and configurations to ensure the system can handle electrical faults safely and effectively.

 

Comprehensive Safety

This test is crucial not only during the development stage but also as the project transitions to the move-in stage. Ensuring safety from the ground up means that everyone on-site is protected from electrical hazards throughout the project’s lifecycle.

By conducting soil resistivity test, we ensure that the soil is suitable for the earthing system and that the system is designed to provide maximum protection. This practical approach is essential for maintaining a safe and reliable environment for both people and equipment. Find out more of our Earthing & lightning protection solutions here.

Microinverters or String Inverters?

Our residential solar PV system provider, Solaroo offers an innovative PV system equipped with micro-inverters which provides 10-30% more energy harvest with unparallel safety compared to a regular string inverter system.

The inverter of your solar PV system is a key component to ensure you system is running well.  An inverter’s primary purpose is to convert the electricity produced by solar panels from direct current (“DC) to alternating current (“AC”) so that it can be utilized for powering your home.

In general, there are two main types of inverters, Microinverters and String inverters.

 

Microinverter vs String Inverter: What’s the difference?

Microinverters and string inverters differ primarily in their location and timing of converting DC energy to AC energy.

 

1. Safety

A string inverter is mounted usually on the ground floor and converts the electrical currents from all solar panels at a central location.  Microinverters are smaller and mounted on the back of the solar panels where they convert the direct current (DC) to alternating current (AC) at the source, making microinverters a much safer option.

With microinverters, there is no build-up of DC voltage as the conversion from DC to AC occurs at the source.  Instead of converting DC to AC at one single source (string inverter), it is well spread out between the numerous micro inverters, operating at a lower voltage compared to string inverters.

 

2. Greater performance

As each panel is connected in parallel to a microinverter, the performance of each panel is independent, providing better performance in situations where some panels might be partially shaded or experience varying conditions.

Referring to the house above, with panels facing every angle, there will be instances where the sun is shinning on certain panels whereas some others may not receive the same sunlight.  With microinverters, as each panel is independent, the generation will be optimized.

This independence in performance is a key advantage of microinverters, offering more flexibility and efficiency in real-world scenarios compared to traditional string inverters.

Pictured above, with a microinverter setup, only the affected solar panel’s output is affected when there is shading as compared to the string inverter, the production of the entire PV system is determined by the performance of the panel with the lowest output

Pictured above, with a microinverter setup, only the affected solar panel’s output is affected when there is shading as compared to the string inverter, the production of the entire PV system is determined by the performance of the panel with the lowest output.

 

3. Better performance monitoring and troubleshooting

Our experienced maintenance team can monitor and identify any fault using the individual panel-level monitoring.  This speeds up troubleshooting instead of having to check every panel to identify the fault.

This further allows us to have panel-level shutdown capabilities when needed, allowing us to isolate and shut down the output of a specific solar panel if needed.  Further enhancing safety in case of a malfunction or maintenance requirement

 

4. Modular design

Microinverters make it easier to scale and expand solar power systems.  Additional panels with microinverters can be seamlessly integrated into an existing system without the need for major redesign or modification.  Most of the time, there will be no change to the internal existing cabling works.

This is a great advantage for our customers whose electricity usage pattern may change overtime with the addition of an EV cars, removal of electricity subsidy, renovation etc.  Having the flexibility to add more panels in the future will help to hedge against the ever-increasing cost of electricity.

Electrifying Safety: Understanding the Essentials of Earthing and Lightning Protection

In an era where electrical systems are an integral part of our daily lives, ensuring their safety and reliability is paramount. One of the often-overlooked aspects of electrical safety is Earthing and Lightning Protection (ELP). Did you know that in Malaysia, lightning strikes are a frequent event owing to its tropical climate and geographical location. The thunderstorms in Malaysia are not only spectacular but also intense and occur frequently. For instance, the Klang Valley experiences an average of 240 thunderstorm days per year.

 

The Shocking Reality: Lightning’s Dangers

Lightning is a powerful natural phenomenon caused by the buildup of electrical charges within clouds. When these charges become imbalanced, they seek to equalize, resulting in a lightning strike. This discharge can carry millions of volts of electricity and reach temperatures hotter than the surface of the sun. The sheer energy released during a lightning strike can wreak havoc on anything it encounters.

Lightning poses a myriad of dangers, from the immediate threat of electrocution to the indirect risks associated with power surges and fires. A direct lightning strike to a structure can cause fires, structural damage, and even fatalities. Indirect effects include electrical surges that can damage sensitive electronic equipment, disrupt power supply, and lead to data loss.

To minimise the damage caused by lightning strikes and power surges, proactive measures are essential. This is where Earthing and Lightning Protection (ELP) comes into play.

 

The Role of Earthing in Electrical Safety

Earthing, also known as grounding, is a fundamental component of electrical safety. It provides a pathway for excess electrical energy, such as from a lightning strike or power surge, to safely dissipate into the ground. Without proper earthing, this energy can follow unintended paths, leading to catastrophic consequences.

 

Surge Protective Devices (SPDs)

Surge Protective Devices (SPDs) are the unsung heroes of ELP. These devices are designed to detect voltage spikes and divert excess voltage safely to the ground. By doing so, SPDs protect sensitive electrical equipment and systems from damage during power surges. They act as a first line of defence against the destructive power of lightning.

 

Best Practices for Implementing ELP

Implementing an effective ELP system involves a combination of strategies and technologies:

  1. Risk Assessment: Begin by assessing the risk of lightning strikes and power surges in your area. Factors like geographical location and the nature of your electrical systems play a role in determining the level of protection required.
  2. Surge Protection: Install Surge Protective Devices (SPDs) at key points in your electrical system, such as main distribution panels and sensitive equipment. Ensure these devices are properly rated and regularly inspected.
  3. Earthing Systems: Establish a robust earthing system that complies with industry standards. This includes grounding conductors and earth rods designed to safely dissipate electrical energy into the ground.
  4. Maintenance: Yearly inspection of your ELP system. Connections should be in a good-shape, and SPDs should be replaced if they have absorbed a significant surge.
  5. Education: Train personnel and occupants on lightning safety procedures. This includes knowing what to do during a lightning storm, such as staying indoors and avoiding contact with conductive materials.
  6. Compliance: Ensure your ELP system complies with relevant industry standards and local regulations. Non-compliance can compromise safety.
  7. Continuous Monitoring: Consider implementing an ELP monitoring system that can detect electrical anomalies and trigger protective measures automatically.

About NEM 3.0

The Government has introduced the Net Energy Metering Scheme in November 2016 with quota allocation of 500 MW up to year 2020 to encourage Malaysia’s Renewable Energy (RE) uptake. The concept of NEM is that the energy produced from the solar PV installation will be consumed first, and any excess will be exported to TNB at prevailing displaced cost.

As an effort to encourage the NEM uptake, the NEM 2.0 was introduced on 1st January 2019, and the true net energy metering concept was adopted, where it allows excess solar PV generated energy to be exported back to the grid on a “one-on-one” offset basis. The NEM scheme were executed by the Ministry of Energy and Natural Resources (KeTSA), regulated by the Energy Commission (EC), with Sustainable Energy Development Authority (SEDA) Malaysia as the Implementing Agency (IA). The 500MW quota under the NEM 2.0 has been fully subscribed by 31st December 2020.

Due to overwhelming response from the PV industry and in an effort to boost the usage of Solar energy, the Energy and Natural Resources Minister via a press statement by KeTSA on 29th December 2020 has introduced the new Net Energy Metering 3.0 programme (NEM 3.0) to provide more opportunities to electricity consumers to install solar PV systems on the roofs of their premises to save on their electricity bill. The NEM 3.0 will be in effect from 2021 to 2023 and the total quota allocation is up to 800 MW. The NEM 3.0 will be divided into the following three (3) new initiatives/categories :-
