Understanding the Cost of Solar Panel Installation
The cost of solar panel installation can vary significantly depending on the system size, type, and quality.

However, the cost of solar panels in Singapore can be different, and we'll explore the specific factors affecting the cost in this article.

Factors Influencing the Cost of Solar Panel Installation
- System Size:** The cost of solar panels increases with the size of the system. Larger systems require more panels, which can lead to higher costs. In Singapore, a 10 kWp solar system can cost between SGD 15,000 and SGD 20,000, or around SGD 300-400 per m² based on 50 m² roof space.
- Type of Panels:** Monocrystalline solar panels are generally more expensive than polycrystalline panels. However, they offer higher efficiency and longer lifespan.
- Installer Reputation and Experience:** Hiring an experienced and reputable solar panel installer can increase the cost. However, it's essential to ensure that the installer is qualified and provides quality workmanship.
- Permitting and Inspection Costs:** Soft costs, such as permitting and inspection fees, can add to the overall cost of the installation.
- Location and Taxes:** The cost of solar panels can vary depending on the location and local taxes. In Singapore, for example, the cost of solar panels includes 7% GST (Goods and Services Tax).
