Feeling the pinch of rising electricity rates? Switching to solar can slash your bill by up to 80 % and lock-in energy costs for 25 years.In this 2025 guide we break down the exact panels, inverters and batteries that work best for Singapore’s hot, humid climate, and show you how Sunollo customers start saving from day 1.
Understanding Solar Power
Before diving into the specifics, it’s essential to understand how solar power works. Solar panels convert sunlight into electricity using photovoltaic (PV) cells. This electricity can then be used to power your home, stored in batteries for later use, or even fed back into the grid. The efficiency and effectiveness of your solar power system depend on the quality of the components and the compatibility of the system with your home’s energy needs.
Key Factors to Consider
1. Type of Solar Panels
There are three main types of solar panels: monocrystalline, polycrystalline, and thin-film.
- Monocrystalline Panels: Known for their high efficiency and sleek appearance, these panels are made from a single crystal structure. They are ideal for homes with limited roof space due to their superior energy output.
- Polycrystalline Panels: Slightly less efficient than monocrystalline, these panels are made from multiple silicon crystals. They offer a cost-effective solution and are suitable for larger roofs where space is not a constraint.
- Thin-Film Panels: These are flexible and lightweight, making them suitable for unique applications like curved surfaces. However, they generally offer lower efficiency compared to the other two types.
2. Efficiency Ratings
Efficiency is a crucial factor as it determines how much sunlight a panel can convert into usable electricity. Higher efficiency panels, though more expensive, will generate more electricity in a given space.
3. Durability and Warranty
Solar panels are a long-term investment. It’s vital to choose products that offer durability and come with extensive warranties. Look for panels that offer at least 30 years of performance warranty and 10-25 years of product warranty.
7. Panel-Level Power Optimizers
Often treated as an optional extra, power optimisers are attached to each panel to mitigate shade and mismatch losses. They can boost overall system yield by 5 – 25 %, provide per-panel monitoring for faster fault-finding, and add rapid-shutdown/arc-fault protection that exceeds basic code requirements. Many installers skip optimisers—arguing they’re “not necessary” to keep upfront costs down—but on roofs with partial shade or multiple orientations, the extra production typically pays back the small premium within just a few years.
4. Inverters
Inverters convert the DC electricity generated by the panels into AC electricity used by home appliances. There are three types of inverters: string inverters, microinverters, and power optimizers.
- String Inverters: Cost-effective and suitable for installations where panels receive uniform sunlight.
- Microinverters: Each panel has its own inverter, allowing for better performance in shaded conditions.
5. Battery Storage
Battery storage systems are crucial for maximizing the benefits of solar energy. They store excess electricity generated during the day for use at night or during power outages. Consider the capacity, lifespan, and compatibility of the battery with your solar system.
6. Installation and Maintenance
Choose a reputable installer with a track record of successful installations. Proper installation is critical for the performance and longevity of your solar power system. Additionally, consider the ease of maintenance and availability of after-sales support.
Choosing the Right Solar Products: A Step-by-Step Guide
Step 1: Assess Your Energy Needs
Start by evaluating your home’s energy consumption. Look at your electricity bills to determine your average monthly usage. This will help you estimate the size of the solar system you need.
Step 2: Evaluate Your Roof
Inspect your roof to ensure it can support solar panels. Consider factors like roof orientation, angle, and shading. South-facing roofs with minimal shading are ideal for solar installations.
Step 3: Research Solar Products
Research different types of solar panels, optimizers, inverters, and batteries. Compare their efficiency ratings, durability, and warranties. Look for products that offer the best balance between cost and performance.
Step 4: Evaluate Financing Options
Consider different financing options, such as purchasing outright, leasing, or power purchase agreements (PPAs). Each option has its pros and cons, so choose the one that best fits your financial situation.
Step 5: Make an Informed Decision
Based on your research and the quotes you receive, make an informed decision. Ensure the chosen solar products and installer meet your energy needs, budget, and long-term sustainability goals.
