Why Go Solar in Singapore and Why 1Solar Makes the Difference The shift to solar energy isn’t just a trend—it’s a smart move. For homeowners in Singapore looking to slash electricity costs, reduce grid reliance and support sustainability goals, solar installations deliver real benefits. But not all solar providers are equal. Here’s what sets 1Solar apart and why investing in solar with us is one of the smartest decisions you can make for your landed home. 1. Reduce Dependence on the Grid Relying entirely on the national electricity grid means you’re exposed to rising tariffs, supply-chain-driven shocks and external risks. Solar power changes that by giving you: Energy independence: With a rooftop PV system, you generate your own power right on your home. Cost-savings: Your monthly electricity bills drop significantly—and if your system produces excess energy, you may earn credits or export back to the grid. Environmental benefit: Solar is zero-emission in generation and helps curb your household’s carbon footprint. In the Singapore context, solar also helps align your property with the nation’s broader Green Plan and energy-resilience goals. 2. Shield Yourself from Rising Energy Prices Electricity tariffs in Singapore have trended upward and will likely continue doing so. A solar system locks in your generation cost now—so you won’t be as vulnerable to future hikes. The independent Energy Market Authority (EMA) notes that solar systems help consumers stabilise their long-term energy costs. Moreover, solar output in Singapore tends to coincide with peak demand periods (often afternoon/evening), which means you’re offsetting high-tariff usage. For landed homes with significant daytime and evening use, this formula can deliver rapid payback and sustained savings. 3. Why 1Solar is the Smart Choice We know that many solar offers claim “no upfront cost” or “free installation”—but those often come with hidden caveats. At 1Solar, we emphasise transparency, engineering excellence and long-term performance: Tailored design for landed homes: Every roof is different—our engineers survey your roof geometry, shading, orientation and usage profile before recommending a system. Clear projections & real payback: We provide realistic ROI timelines and savings estimates—not inflated promises. Quality installation & post-care: From high-grade modules and inverters to monitoring systems and ongoing support, your system is built to perform. Local expertise for Singapore’s climate: Singapore’s tropical weather (storms, humidity, monsoons) demands more than just “generic” solar panels. We design for resilience. 4. Key Considerations Before You Commit While solar has major upside, it’s still important to ensure a good fit. EMA outlines a few key factors: Roof suitability: Unshaded roof space, good tilt/orientation, and structural condition matter. Consumption profile: Higher daytime usage accelerates payback. Low usage may stretch ROI. Long-term ownership: Solar is a long-term investment (20-25 years). If you plan to move soon, factor in how the system carries over. System costs & real savings: Ensure you understand full cost, maintenance, inverter replacements, and expected output. 5. Start Your Solar Journey with Confidence In Singapore, where land is limited and renewable options are constrained, solar remains the most viable choice for homeowners seeking energy independence. At 1Solar, we’re committed to making your rooftop a long-term asset—not just a panel installation. If you’re ready to explore how much your home could save and how fast you can reach break-even, we’re here to help. Contact Us Ready to unlock your roof’s potential?

What to Look for When Choosing a Solar Provider in Singapore — The 5-Point Homeowner Audit Investing in solar energy is one of the smartest moves a Singapore homeowner can make — it reduces long-term electricity bills, boosts property value, and helps contribute to the nation’s Green Plan 2030. But as solar becomes more mainstream, not all installers deliver the same quality, performance, or transparency. Choosing the wrong provider can lead to hidden costs, under-performing systems, or even roof damage. Here’s a 5-point checklist every landed-home owner in Singapore should use before signing any solar contract. 1. Engineering Before Marketing A trustworthy solar provider starts with engineering, not sales talk. Look for companies that: Conduct an on-site roof inspection before giving you a quote. Evaluate tilt, shading, and structure integrity – not just your electricity bill. Offer customised layouts optimised for your specific home, not copy-paste proposals. At 1Solar, every project is engineered by certified specialists who design for Singapore’s tropical heat, rainfall, and humidity — ensuring both safety and maximum energy capture. Tip: Be cautious of providers who sell purely on “zero upfront cost” or “free solar.” These often involve lease or rent-to-own schemes that cost more long-term. 2. Transparent ROI and Cost Breakdown Solar is a long-term investment — and your provider should help you understand the numbers clearly. Ask to see: Your estimated annual savings and breakeven period (usually 3–5 years). The assumptions behind those figures — sunlight data, tariff rates, maintenance. A comparison between ownership vs rental models, so you know which is truly better. 1Solar clients receive full financial breakdowns with realistic ROI projections — no exaggerated claims or fine print. Pro tip: In Singapore, landed homeowners can typically offset up to 70% of their monthly bill with a well-designed system. 3. Quality Components and Workmanship Your solar system’s lifespan depends on the equipment quality and installation skill. Ensure your provider uses: Tier-1 solar panels and reputable inverter brands. Waterproof mounting systems compatible with your roof type. Qualified electricians and certified installers. 1Solar partners only with trusted manufacturers and certified teams, backed by warranty and post-installation performance monitoring. 4. Track Record and After-Sales Support Many companies appear overnight when solar demand spikes — then disappear when issues arise. Before choosing, ask: How long has the company operated in Singapore? Can they show completed local projects similar to yours? Do they provide remote monitoring and maintenance support? 1Solar’s clients consistently highlight our after-sales responsiveness — our engineers have even gone on-site after hours to troubleshoot unrelated electrical issues. Reliability matters more than flashy discounts. See 1Solar's Track Records 5. Local Compliance and Safety Assurance Solar work involves structural and electrical integration — not just panel placement. Choose a provider that: Complies with Building and Construction Authority (BCA) and Energy Market Authority (EMA) standards. Submits necessary applications and handles SP PowerNet coordination. Conducts safety checks before, during, and after commissioning. 1Solar manages every technical and regulatory step to ensure your system is safe, compliant, and seamlessly integrated into the grid. The Bottom Line: Choose Expertise, Not Hype Solar is a decades-long investment. The difference between a good and a great provider is in their engineering accuracy, integrity, and long-term support. At 1Solar, we don’t oversell — we educate, design, and deliver systems that perform exactly as promised.

How to Calculate Your Solar Payback Period — A Guide for Singapore Landed Homeowners Installing solar panels isn’t just about going green — it’s a smart financial decision.In Singapore, where electricity tariffs have been rising steadily, a properly designed solar system can recover its cost within just a few years, then generate pure savings for the next two decades. If you’re exploring solar for your home, here’s how to estimate your payback period accurately — and avoid common calculation mistakes that many homeowners make. 1. What Is Solar Payback Period? Your payback period is the time it takes for your total electricity savings to equal the amount you spent on installing your solar system. In short: Payback Period = System Cost ÷ Annual Savings Once you pass that point, your solar panels are essentially generating free electricity — and everything after is profit. 2. Average Payback for Landed Homes in Singapore For most Singapore landed properties, payback typically ranges between 3 to 5 years, depending on: Roof size & sunlight exposure (more panels = higher output) Electricity consumption (homes with higher usage save faster) System cost (varies with equipment quality & inverter capacity) Electricity tariff rates (which have been trending upward yearly) At 1Solar, we’ve seen clients achieve break-even in as little as 3.2 years, with annual savings of up to $15,000 depending on their roof and usage. 3. Step-by-Step: How to Estimate Your Solar Payback Let’s break it down in a simple 3-step approach. Step 1: Find Your Annual Energy Consumption Look at your SP Group bill — note your monthly kWh usage and multiply by 12.For example: 2,000 kWh/month × 12 = 24,000 kWh/year Step 2: Estimate Your Solar System Output A well-designed system in Singapore generates about 1,200–1,400 kWh per kWp annually.If you install a 10 kWp system, you can expect roughly: 10 × 1,300 = 13,000 kWh/year That’s about 54% of your home’s energy use offset directly by solar. Step 3: Calculate the Payback If your 10 kWp system costs $18,000, and your yearly savings are around $4,500, your payback period will be: $18,000 ÷ $4,500 = 4 years After year 4, your home enjoys over a decade of near-zero power bills. 4. Factors That Influence Payback Your results depend heavily on these 4 variables: System Quality: Cheaper panels may degrade faster and underperform in Singapore’s heat. Roof Orientation: South-facing roofs get the best sun exposure here. Electricity Prices: The higher the tariff, the faster your payback. Usage Timing: Homes that consume more power during the day benefit most. At 1Solar, we perform detailed on-site simulations to ensure every system achieves optimal ROI based on your real roof geometry and lifestyle. 5. Beyond Payback — The True Value of Solar Once your system has paid for itself, your roof essentially becomes a profit-generating asset: 20+ years of free electricity Reduced carbon footprint (~3–5 tonnes CO₂ saved yearly) Increased property value (solar-equipped homes often sell faster and higher) Energy independence — less reliance on grid fluctuations And with SP Group’s grid export scheme, any excess energy can earn you credits, improving your overall returns even further. 6.
