• When exposed to the sun, solar panels capture light particles in order to generate voltage or electricity. They thus offer a cost-effective way for households to supplement their electrical supply and lower their electric bills.
• There is, however, a misconception that solar-powered homes experience electrical supply disruptions at night.
• In Singapore, all houses with solar panels are still connected to the electricity grid. Homeowners can sell excess electricity generated in the day to the grid and will not experience any electrical outages. There is also no need for battery storage to supply electricity at night
• So even on rainy or cloudy days, you’re not at the risk of experiencing electrical outages at home.

The simple answer is perhaps. The long answer is that your residence uses solar-generated electricity, for which you will not be charged any electricity costs. If you still require additional power, the electricity grid will be utilised. You will pay for this electricity to your electrical company.

Solar panel installation costs in Singapore vary from $10,000 to $50,000, with the average landed property owner costing around $20,000 for a ten kWp system, or $2,000/kWp. 

The cost will vary according to the number of solar panels installed, the kind of roof used, its orientation, and the installation technique. Most Singaporean property owners install as many solar panels as possible on their rooftops because larger systems offer lower unit prices.

However, you should consider how much electricity you consume monthly and construct your solar system to fit your demands for daytime electricity.

Although this depends on various factors, including the quantity of the solar panel system and the household’s electricity use habits, the estimated duration necessary to recoup the cost of the solar panels through energy efficiency is roughly seven years. Some residences achieve financial stability in four to five years.

Step 1: Install the mount.

The first phase includes constructing the structure (which may include adding rails or bolts) that will be used to secure the solar panels to your roof.

Step 2: Set up the solar panels.

The panels are hoisted to the roof and firmly fastened to the pre-installed fixtures.

Step 3: Perform electrical wiring

After the solar panels have been installed, the photovoltaic system must be wired in order to connect them.

Step 4: Attach the solar inverter to the system.

The solar inverter converts the direct current generated by the solar panels to alternating current, which is used to power homes. If you want to store energy, an optional battery or storage device is available, but it is pricey (an additional $10,000).

Step 5: Link the solar inverter to the power grid.

The electrical grid that receives the electricity must then be connected to the solar inverter.

Step 6: Begin the solar inverter.

The solar inverter is eventually turned on to power up the solar panel installation. This generally only takes a few minutes.

Pros of installing solar panels

• Eco-friendly and combats climate change by lowering carbon emissions
• Reduced electricity bills
• Long lifespan
• Affordable maintenance costs
• Can make a profit by selling excess electricity
• Can increase home value

Cons of installing solar panels

• High upfront costs of purchasing solar panel system
• Not all roofs are right for solar panel systems
• Can be weather-dependent
• High chance of improper installation

It is feasible to install a solar panel system on a rooftop as long as there is no or slight shadowing.

It is feaDepending on the weather, everyday residential work will take 1 to 2 weeks to finish.

We always use non-penetration installation, where our specialized clamps are fastened to roof-mounted solar mounting systems. The waterproong coating of the roof won’t be damaged.

Solar panels:

• Manufacturer warranty of 25 years (1-1 replacement for any defective panels)
• Performance warranty of 25 years(Guarantee that panel deterioration won’t exceed 0.7 per cent per year)
• Labor warranty of 25 years(For systems under 25 kWp, the costs of uninstalling, reinstalling, labour, and transportation for damaged panels may be claimed.)

Solar Inverter:

• Limited 5-Year Warranty

SS Workmanship:

• Limited 2-Year Warranty

It’s unlikely, although it does happen on occasion. Solar panels are designed to survive adverse weather conditions. Some first-generation solar panels are still operating and generating 75% of their original output after 40 years. Because it is a simple piece of machinery with no moving components, issues are infrequent.

Panels are comprised of stationary machinery and tough tempered glass. As a result, for the 25 to 35 years, it requires little to no maintenance. As maintenance, simple surface cleaning and cable checks should be performed every two to three years. Typically, panels are slanted between 5 and 10 degrees to wash off rainwater and minimise water stagnation.

With fewer grid costs, surplus electricity will be sold back to the grid at the calculated tariff value.

Once installed, your Solar Panels will begin producing power for the property. Based on when you obtain your electricity bills, you may notice lower expenses as early as the first month.

One of the primary reasons is the availability of local customer services; REC has a production operation in Singapore (Tuas) and its headquarters in Norway. Damaged panels can be easily changed. They have the industry’s lowest failure rate of 1 in 10,000. REC is the industry’s only solar company that provides a 25-year product warranty. By far the sole manufacturer giving a labor warranty of 10 to 25 years

Certainly, if you reside on a landed property, but not completely. A licensed electrical worker (LEW) must endorse a system before it can be installed. That is why hiring a professional is strongly advised; you are likely inexperienced with the safety regulations and the construction and electrical laws and guidelines.

Land property owners are not required to apply for building authorisation. Unless you reside in a conservation area, plan to install lifted solar panels one to 1.8 meters over your roof or seek to use the space beneath the solar panels for commercial purposes.

If you reside in a condo penthouse, you can ask your MCST for permission to operate a solar panel installation. You will not, however, be permitted to transfer or sell extra electricity to the grid and may be held accountable for any dangers to the property.
