A high-performing home system is built from several core products: solar panels, inverters, optional batteries, and smart monitoring, selected and sized to your needs. This guide breaks down the best solar products for homes in Singapore and how to choose what fits your landed property or rooftop best.

📌 TL;DR - key takeaways on choosing the right solar products for your home

• The most important solar components for homes are: panels, inverters, mounting system, and monitoring software.
• Choose Tier-1 solar panels with strong warranties (25–30 years) and proven performance in hot climates.
• Hybrid inverters are ideal for future battery upgrades; microinverters are best for shaded roofs.
• Singapore homeowners should prioritize heat tolerance, roof compatibility, and local after-sales support.
• Ask for a full system warranty and ensure your installer is EMA-licensed and experienced.

Recommended solar panels

In Singapore, where space is a constraint, efficiency is the single most important factor when choosing a solar panel. You need a panel that converts the most sunlight into electricity per square metre.

Monocrystalline panels offer the highest conversion efficiency, typically reaching 20% to 22% or higher. While they have a higher initial cost than less efficient Polycrystalline panels, their superior performance in limited space translates directly into a faster return on investment (ROI) and a higher total energy yield over the system's lifetime. They also feature a uniform black colour, offering a sleek, premium aesthetic favored by many homeowners.

When selecting a brand, focus on Tier 1 manufacturers. This classification is used to identify financially stable companies with proven bankability, ensuring that the 25-year performance warranty provided on the panels will be honoured decades down the line. Trusted Tier 1 brands to consider include REC and Trina Solar.

Recommended solar inverters

The inverter is responsible for converting the raw DC electricity from the panels into usable AC electricity for your home. Since partial shading from nearby trees, vents, or adjacent buildings is a common issue on Singaporean roofs, the choice of inverter technology is paramount for efficiency.

There are three main inverter options available to homeowners: string inverters, microinverters, and hybrid inverters. Most landed homes with simple roof layouts and minimal shading do extremely well with string inverters. They’re cost-efficient, durable, and easy to maintain. However, roofs with many angles, chimneys, or partial shading benefit from microinverters, which work independently for each panel and prevent shaded sections from dragging down the entire system.

Hybrid inverters are becoming popular because they are designed to accommodate a home battery in the future. Even if you don’t plan to install a battery today, choosing a hybrid inverter allows flexibility later as energy prices, regulations, or lifestyle needs evolve.

Regardless of inverter type, homeowners should prioritise high efficiency (generally above 97%), strong warranty coverage, good heat management, and local technical support. The inverter is typically the component most likely to need servicing within the system’s lifetime, so choosing a reputable brand with reliable after-sales service is crucial.

Roof compatibility and mounting systems

A solar system is only as strong as the structure holding it. Mounting systems differ depending on roof type. Metal roofs typically use clamping systems that minimise penetration, while clay tile roofs require specially designed hooks that prevent tile cracking. Flat roofs use ballasted systems that rely on weight instead of drilling.

Homeowners should ensure their installer conducts a proper structural assessment and takes steps to preserve waterproofing. Because Singapore experiences heavy rainfall and strong winds, mounting hardware must be corrosion-resistant, durable, and installed with careful attention to safety standards.

Monitoring and smart energy management

Today’s solar systems are incomplete without a good monitoring platform. These apps give homeowners real-time visibility into how much energy the system is generating, how much they are saving, and whether any component requires attention. Monitoring ensures transparency to easily verify that your system is performing as promised.

More advanced platforms provide detailed insights into long-term performance trends, energy consumption patterns, and early warnings if output drops unexpectedly. These analytics tools help homeowners maximise savings and maintain peace of mind throughout the system’s lifespan.

🔎 FAQ

1. What is the most important component in a home solar system?
Both panels and inverters are critical, but installation quality and long-term support matter just as much.

2. Can all homes in Singapore install solar panels?
Most landed homes can, though roofs with heavy shading or structural limitations may need alternative layouts. A site assessment is essential.

3. How long does a solar system last?
Typically 25 years or more, provided you choose good components and reputable installers.

4. Do I need a battery?
Not necessarily. It enhances energy independence but is optional. A hybrid inverter allows easy upgrading in the future.

5. What warranties should I expect?
At least 12–25 years for panels, 5–10 years for inverters, and a clear workmanship warranty from the installer.
