Why Install Solar Panels?

Solar panels are not merely a trend; they are a long-term investment in a sustainable future. Here’s why you should consider installing solar panels:

Electricity Cost Savings


Solar panels are a financially prudent choice. According to industry experts, solar panels can last for at least 25 years and are able to pay for themselves within 6 to 8 years, offering a high return on investment (ROI). This is a significant advantage over traditional energy sources, which often involve ongoing costs and lower ROI. With the Russia-Ukraine war, increased demand for electricity and a shortage of electrical alternatives, home electricity rates will only rise.

As of January 2023 from SP Group, Singapore has experienced a significant increase in electricity prices due to global economic conditions. Solar panels offer a sustainable and cost-effective solution to this issue, providing another compelling reason to make the switch.

Low MaintenanceWith minimal upkeep, the running costs are significantly low.
Energy SavingsReduce your electricity bills by up to 20%.

On the other side, solar electricity is getting cheaper and cheaper. Did you know that the cost of solar internationally has decreased by 89% in the previous 10 years? People frequently think solar is pricey yet it is actually the cheapest method of electricity generating presently. This is in great part owing to more efficient technology and reduced costs as solar becomes more mainstream.

Low Maintenance Costs

Another financial benefit of solar panels is their low maintenance requirements. Once installed, solar panels require minimal upkeep, which means the running costs are significantly low. This is in stark contrast to other forms of energy production that require regular maintenance and additional expenses.

Environmental Benefits

Solar panels significantly reduce the carbon footprint by emitting zero greenhouse gases, presenting an environmentally friendly energy solution. They harness solar energy, which is both renewable and abundant, ensuring a sustainable source of power. Moreover, the use of solar panels involves a low environmental impact, as they operate without the need for harmful extractions or emissions, making them a cleaner and greener choice for energy consumption.

Operate A Home Purely On Solar Energy

The size of your solar system and how much power you utilize at home will decide this. After converting to solar, some homes could truly pay $0 a month on power. In fact, on a bright day, you may even create more electricity than your home uses and earn by selling the surplus to the grid!

In reality, we have a number of testimonies that attest to the practicality of powering your home completely with solar panels.

Batteries To Power My Solar Energy System

Most of the time, no. Since surplus solar energy may be sold back into the grid, grid-tied solar panel systems in Singapore are widely utilized and do not need batteries.

When it is bright outside, your house will first utilize the solar energy generated by your system to make power. If you consume more energy than is generated, the device will automatically take electricity from the grid. Your house will continue to collect electricity from the grid as normal at night when your system is not generating energy, so there won’t be any power outages. The end outcome? You save money on electricity as you utilize the grid substantially less.

Installing batteries is normally not suggested owing to their high cost (they might raise the cost of your system by $10–20,000 at this time). However, installing battery-ready inverters will make it easy for you to add batteries later on when costs decrease.

Install Solar Panels In A HDB Flat

Almost 80% of Singaporeans live in a HDB apartment. Unfortunately, this majority doesn’t have the opportunity to make adjustments such as placing solar panels on their HDB roof. Thankfully, HDB’s Green Towns Programme proposes to deploy 540 MWp of solar panels on Singapore HDB estates by 2030.

Install Solar Panels If I Live In A Condominium Or MCST

Condominium complexes are communal living areas and may have limitations stopping you from installing solar panels. However, if you’re the owner of a penthouse or MCST landed property and would want to acquire a solar panel installation, here are some key suggestions to consider:

  • You will need to first receive consent from your condominium Management Corporation Strata Title (MCST)
  • You will not be able to export or sell any extra power to the grid
  • The solar system installed will be deemed a “hobby” installation and you may have to be accountable for any dangers to the condominium
    Refer to this article on installing solar panels for condominium or strata landed properties for everything to consider.

Solar Panel Cost in Singapore

The cost of installation will vary dependent on numerous variables, including the amount of solar panels installed. The cost of a solar panel installation in Singapore varies from S$15,000 to S$38,000 or more. That stated, a fair estimate would be S$20,000 since most home solar panel systems are roughly 10 kWp (S$2,000/kWp).

While a 1,000 kWp industrial rooftop PV system might cost roughly S$940/kWp. Besides the quantity of solar panels placed, the operation and maintenance expenses vary from 1 to 1.45% of upfront expenditures (1% for big rooftop systems compared to 1.45% for smaller systems). For further pricing information you may refer to the 2020 “Update to the Solar PV Roadmap for Singapore ” paper, the National Solar Repository website or you can just contact out to us.

Warranty and maintenance for solar panels in Singapore

Most solar panels carry a 25-year power output guarantee in addition to a 12-year product warranty. Solar inverters, however, frequently come with a 5-year manufacturer’s warranty. These warranties frequently involve replacements of any physically faulty equipment on a one-for-one basis.

This suggests that even when new solar panels will be delivered at no cost to you if you need them within the warranty period, you might still be liable for paying your installer’s labor costs for the repair process. Solar panel installation providers often charge maintenance and cleaning charges in Singapore, which may range from $300 to $500 for every visit.

    Frequently Asked Questions

    Not only does it help to save electricity bills, solar panel installations can also raise the value of your property. According to surveys, homes with solar panel systems sell 20% faster and for 17% more money. While these percentages may vary in the Singaporean context, the trend is clear: solar energy is an enticing factor for homebuyers.

    The three important criteria that decide whether your roof is ideal for solar panels are as follows: Size, Shade Amount, Angle & Direction, and Size.

    Solar panels may be put on most roofs. Solar panel installations would not be the greatest solution for roofs that are exceedingly intricate or shaded. A smaller system may fit on a smaller roof, which frequently gives a worse rate of return on investment.

    In terms of financial incentives, Singapore offers several schemes:

    1. Net Metering Schemes: These are quite beneficial if you’re planning to install solar panels.
      • Simplified Credit Treatment (SCT) Scheme: Mainly for residential installations. If you’re buying your electricity from SP Services and your system is under 1 MWac, you can benefit from this. It allows you to sell any excess solar energy back to the grid at about 75-80% of the SP Group’s electricity tariff rate. For example, as of Q3 2022, the rate was around $0.2423 per kWh​​.
      • Enhanced Central Intermediary Scheme (ECIS): This is for both residential and commercial installations, especially if you’re a contestable consumer (choosing your electricity provider). The scheme compensates you based on the half-hourly wholesale energy prices, which vary but are generally lower than SP Group’s rates in the long term​​.
      • Market Participant (MP): This is tailored more for commercial setups with installations over 10 MWac. Here, you directly engage with the Energy Market Company (EMC) and get compensated based on nodal energy prices, determined by the market demand and supply​​.
    2. Renewable Energy Certificates (RECs): These are quite interesting and can be a game changer. Essentially, they are tradable certificates that represent the green electricity your solar panels generate. Each REC equals 1MWh of electricity. You can sell these to companies looking to offset their carbon emissions, adding an extra layer of financial benefit to your solar installation​​.
    3. Energy Efficiency Incentives: Particularly notable is the Green Mark Incentive Scheme for Existing Buildings (GMIS-EB 2.0). This scheme supports energy-efficient retrofits in buildings, with incentives up to $1.2 million or 50% of qualifying costs. It’s part of Singapore’s broader strategy to turn most buildings green and energy-efficient by 2030​​.

    Evaluating Your Roof in Singapore

    When considering solar panels for your home in Singapore, here are the key factors to assess:

    1. Orientation and Inclination: Given Singapore’s geographical location, just about 1 degree north of the Equator, the orientation of solar panels is less critical compared to regions further from the equator. In Singapore, solar panels can be installed flat and horizontal, maximizing the exposure to the sun’s path. However, it’s beneficial to tilt them slightly at an angle of about 5 to 10 degrees. This slight inclination helps with self-cleaning as it allows rain to wash away any accumulated dust or debris, maintaining the efficiency of the panels.
    2. Roof Size and Condition: Ensure your roof has sufficient space for solar panel installation. On average, a typical panel is about 1.5 to 2 square metres. For a small home system, you’ll need a clear roof area of around 15 to 30 square metres. Additionally, the roof should be in good condition to bear the weight of the panels.
    3. Shading: Buildings or trees that cast a shadow over your roof can significantly diminish the efficiency of solar panels. In the high-density urban environment of Singapore, this is an important consideration.
    4. Building Regulations and Permissions: It’s essential to check with your building management or the relevant authorities in Singapore regarding any regulations or permissions needed for solar panel installation.

    You may, particularly if you live in landed property – you wouldn’t need to apply for planning permission unless you’re

    1. Utilizing the space beneath your solar panels commercially
    2. Reside in a conservation area, or
    3. Want to put raised solar panels (one meter or more over your roof

    You will, however, require a professional electrical worker’s endorsement of the system you put up. So unless you have the know-how, you’d probably be better off contacting us who is knowledgeable with safety requirements and construction and electrical restrictions.
