Solar-powered appliances have risen in popularity, given that they are sustainable and their usage can significantly reduce electricity bills. However, installing solar roofing, such as solar shingles, is a major investment, so homeowners need to understand the associated costs before making the switch. They can make an informed decision and ensure they get the best value for money by researching solar roofing options, including material prices, quality, features, and reputable brands.

Solar roof shingles
Solar shingles, also known as solar roofs, solar tiles, or solar roof tiles, are tile-shaped panels permanently installed on the roof. They are smaller than conventional solar panels but operate in a similar way.

The average size of solar shingles or tiles is about 12 inches wide by 86 inches long. Based on the size, it can take about 350 solar tiles for a standard-size roof, but this is completely dependent on the size recommended by the manufacturer and installation expert.

Average price
The rapidly growing market for solar roof shingles and technological advancements are driving manufacturers to compete to provide the best value to consumers. The typical cost of a solar-enabled roofing system, such as solar shingles, can range from R60,000 to R150,000, depending on the size and features of the system.

Factors influencing price
The rising demand for solar roof shingles can result in price fluctuations. Various external factors, including the changing prices of materials like silicon and copper and shifts in global demand, influence the overall cost of solar roofing. Additionally, peak installation seasons can drive costs even higher. It is important to be aware of other factors as well.

• System size
  The size of the solar system plays a major role in determining cost. A larger system has higher upfront costs because of greater capacity and more components. For example, a 20 kW system costs more than a 13 kW system because it produces more electricity.
• System type
  The type of system also affects the price. For instance, a grid-tied system is more affordable than an off-grid one, as it is linked to the main power supply, offering a backup battery during cloudy days or rain. An off-grid system functions independently and needs more battery storage, which can drive up costs.
• Inverter type
  A solar roof has various components, such as an inverter. An inverter is required to convert the direct current (DC) electricity generated by solar shingles into alternating current (AC) power usable in homes. Investing in high-quality inverters, especially those with features like monitoring capabilities and high-efficiency settings, may incur a higher initial cost; however, it can enhance the overall performance and longevity of the solar system.
  A micro-inverter, for example, can increase efficiency in areas that experience partial shading and provide better monitoring of individual panel performance. So, solar inverters’ prices can vary widely depending on these factors, ranging from R10,000 to R80,000. For example, a Tesla solar roof, which comes with a Powerall battery, averages about R87,490 for a 12-panel solar system.
• Installation complexity
  The technical installation of solar roofing can also hike the project’s cost. Installing solar shingles on a flat roof can cost more for additional mounting structures. Even a roof with tricky designs can influence the cost. If shading is an issue, experts may need to install optimizers, which can result in further costs. Generally, installation charges range from 20% to 30% of the total system price.

Expected ROI
Since the cost of installing solar roofing might be a significant investment for many, a homeowner can eventually expect a return on investment over 5 to 8 years. For instance, a dedicated smart monitoring system can deliver real-time data on energy output and consumption based on energy savings and system performance. The data-driven approach to energy management is essential for optimizing system efficiency and maximizing savings over time.

Incentives and rebates
Homeowners can also look for incentives and tax rebates from the government to save on the overall cost of installing solar roofing. There are even financing options like green loans and flexible payment plans to make the institution more affordable and accessible to a larger audience.

Benefits of solar roof shingles

• Solar shingles seamlessly blend into the roof, making them visually appealing and preserving the home’s overall look.
• They help reduce energy bills and lessen environmental impact.
• Solar shingles are designed to be durable and weather-resistant, which is why manufacturers often provide warranties covering specific wind speeds. This is quite reassuring for homeowners. Some manufacturers even offer warranties that guarantee a certain level of energy output.
• Solar shingles can be installed on most homes. Additionally, solar roofing makes use of diffused and scattered light, allowing it to function effectively even on overcast and rainy days.

Tips for purchasing solar roofing or shingles

• Assess current needs
  Assessing the current electricity consumption is crucial to determine the number of solar panels required and the potential long-term savings from switching.
• Pick relevant solar tile material
  Some solar roof tiles are more efficient and good for smaller roofs, while others are more affordable. Some solar tile manufacturers offer lighter, more flexible options; however, these are less efficient.
• Consult an expert
  Since solar roofing is an extensive project and quite an investment, consulting a professional for a thorough roof inspection and solar assessment is best. The best ways to pick an expert include reading reviews and credentials of different solar companies and collecting more than one quote.
• Obtain required permits
  Every household is bound by rules and regulations set by local governing bodies. It is important to select a solar roofing option that is legal. The homeowner should also get approved for permits before installing the solar tiles.
