Renovate Now, Save Later: The Ultimate Guide to Solar Installation During Home Renovations

As more Malaysian homeowners look for ways to save on rising electricity bills and make eco-friendly home improvements, integrating solar power during renovations has become a smart choice.

The convenience of planning a solar installation while upgrading your home not only saves time but also offers long-term financial benefits. One company leading the charge in this space is Brilliant Solar, a trusted provider with more than 16 years of experience and a track record of over 2,000 successful projects across Malaysia.

Beyond convenience, the financial benefits are significant. Solar panels immediately reduce electricity bills and can increase property value. This particularly appeals to buyers and renters keen on energy-efficient homes. For homeowners with higher energy demands, such as larger properties, upgrading to a three-phase power supply during the renovation can maximize solar efficiency and savings.

Key Roofing Factors for Maximising Solar Efficiency

An efficiently designed solar power system like Brilliant Solar’s should generate at least 3.3 peak sun hours of energy on average throughout the year. Peak sun hours refer to the period when sunlight is at its strongest, allowing for optimal energy production per square meter. 

Thanks to Malaysia’s tropical climate, we’re able to receive an average of 4.0 to 5.0 peak sun hours per day, depending on the location. To further optimize performance, factors such as roof pitch and shading play an important role in ensuring maximum energy output: 

• Roof angle: It’s important to consider the angle or pitch of your roof. A slope of about 5° is perfect for energy yield. Slopes that are too steep may reduce the efficiency of your solar panels.
• The ideal condition: A South-facing metal deck roof (clip-lock style) with a 4-5° slope and free from shadows or shading proves to be the ideal condition for maximum solar performance.

The Ideal Time to Install Solar During Renovations

Home renovations offer the perfect opportunity to incorporate solar power. It’s a one-time chance to lay the groundwork for a future-proof home without the hassle of post-renovation installations. The best time to install a Brilliant Solar system is before adding the plaster ceiling. This is so that the wiring for the solar system can be implemented together with the general wire to save the homeowner’s time and budget. By planning ahead, homeowners can avoid the mess of drilling and reworking ceilings later on.

Tailored Solar Solutions for Every Roof Type

Brilliant Solar’s personalized approach ensures that every installation is optimized for efficiency and durability. Here’s how they tailor their installations based on your roof type:

• Metal deck roofs: Installed using a clip-lock system that requires no drilling, avoiding the risk of leaks.
• Concrete roofs: Fitted with adjustable racks that ensure the panels are properly angled for maximum sunlight exposure.
• Tile roofs: Equipped with specialized brackets that lift the panels above the roof, promoting airflow and preventing overheating. Before installation, it’s essential to ensure the tiles are in good condition (not broken) and that there are no existing leaks. If possible, consider replacing the roof during renovation, as installing solar panels is a long-term investment. Installers will open roof tiles one by one and secure the solar system by screwing it to the roof truss for added stability.

Understanding the Solar Panel Wiring Process

The wiring process in solar installations is designed to ensure both functionality and safety. Solar panels produce direct current (DC) power, which is sent to an inverter for conversion to alternating current (AC), making it suitable for household use. The wiring from the panels to the

inverter, and then to the Solar DB and the house’s main distribution box, can be hidden within walls or secured in a protective casing, based on the homeowner’s choice. Allowing enough space around the inverter is important to maintain airflow and prevent overheating, ensuring longevity and performance. Homeowners are also encouraged to dedicate a specific outdoor spot for both the inverter and Solar DB for easy access and maintenance.

Choosing the Suitable Inverter for Your Solar System 

Homeowners can choose between two types of solar inverters:

• Microinverter systems: Perfect for setups where each panel needs to operate independently, such as car porches or shaded areas. Microinverters provide better performance in low-light conditions but may require more maintenance over time.
• String inverter systems: These are more cost-effective for homes with good airflow and plenty of sunlight. They are typically installed in areas protected from rain and direct sunlight, which helps extend the system’s lifespan.

Brilliant Solar helps homeowners decide on the best option based on their property layout and energy needs. This ensures that the system is tailored to provide maximum efficiency and savings, while also accommodating the homeowner’s specific needs. With the team’s expert guidance, homeowners can confidently choose an inverter system that complements their unique installation, ensuring long-term performance and reliability.

For Malaysian homeowners, installing solar during a renovation is a strategic move that offers both immediate and long-term benefits. Whether it’s reducing electricity bills enhancing property value, or contributing to a greener planet, solar energy is an investment that pays off. With Brilliant Solar’s expertise, coordinating solar installation during the renovation process is seamless and mess-free.

Government Incentives for Solar Adoption

Malaysia is committed to expanding the use of renewable energy, and the government offers various incentives to encourage homeowners to adopt solar power. One key initiative is the Net Energy Metering (NEM) program, which helps homeowners lower their electricity bills by generating solar energy. Any extra energy produced can be sent back to the grid, earning credits and further reducing future costs. These efforts make solar power more affordable and support Malaysia’s goal of cutting carbon emissions and reaching net zero by 2050.
