What is the upfront cost of a solar installation?

The cost of installing solar panels on a building in Singapore can vary depending on several factors, such as the size of the system, the type of panels used, and the complexity of the installation. As of 2024, the typical cost for a solar power system in Singapore ranges from  S$1 to S$2 per watt-peak (Wp) installed.

With Sunollo's no-worries solar plan, the upfront cost of a solar installation is as low as S$0, and you are able to start saving from the first month onwards.

How does net metering work?

Under the net metering scheme, any excess electricity that your solar system generates and exports to the grid is credited back to the consumer at the prevailing wholesale electricity prices. These credits can then be used to offset your future electricity bills.

The amount of money you can earn from the net metering scheme in Singapore will depend on several factors, including the size of your solar system, your electricity consumption, and the prevailing wholesale electricity prices. Solar panels can help you generate more electricity, thus increasing your potential earnings from your solar energy exports to the grid.

How long do solar panels last?

Most solar panels come with warranties ranging from 20 to 25 years, but they can last much longer with proper maintenance. The degradation rate of solar panels is typically around 0.5% to 1% per year, meaning they can still operate at a high efficiency for decades.

Is my roof suitable for solar panels?

Most roofs are suitable for solar panel installation, as long as they have unobstructed access to sunlight for a significant portion of the day. Factors such as roof orientation, shading, and available space will influence the efficiency of solar panel installation.

Do solar panels require maintenance?

Solar panels are relatively low-maintenance, requiring occasional cleaning to remove dust and debris that may accumulate on the surface. Additionally, it's recommended to have a professional inspection every few years to ensure optimal performance.

Can solar panels work during cloudy or rainy days?

While solar panels generate the most electricity on sunny days, they can still produce power during cloudy weather due to diffuse sunlight. However, they do not generate electricity at night unless paired with energy storage solutions like batteries.
