What are the advantages and disadvantages of solar roof tiles?

Nov. 11, 2022

With the popularity of solar energy, people continue to express a desire for more choices in solar products. Then solar panels are becoming an increasingly common sight in homes as the technology becomes more affordable and efficient at generating renewable energy. As an alternative to panels, however, a new technology called solar roof tiles is gaining popularity. Here, we will explore the knowledge of solar roof tiles, including how they work and their advantages and disadvantages.

What Are Solar Roof Tiles?

Solar roof tiles, also known as solar shingles or solar slates, are a relatively new green energy technology. The finished look of solar shingles is much less aesthetically disruptive than traditional solar panels because they blend seamlessly into the roof. The remarkable feature of solar roof tiles is how they are adapted to different styles.

How do solar roof tiles work?

Solar tiles work on the same principle as photovoltaic panels, which are widely used in construction. The main difference is the assembly: the photovoltaic panels are fixed to the existing roof; Solar tiles have been part of the roof structure since the beginning of construction, replacing conventional tiles. The tiles are made of photovoltaic cells. The electromagnetic fields they generate after absorbing sunlight provide electricity to the interior of the building. Each tile is connected to the switchboard by a cable.

To ensure the efficiency of the shingle operation, each shingle needs to be installed with a solar inverter that converts the generated energy into electricity, converting it into alternating current (AC) energy that can power your home.

The advantages of solar roof tiles

● Aesthetically Pleasing

Solar roof shingles are aesthetically pleasing compared to older large solar photovoltaic panels. It's still striking but looks more stylish and modern. Another consideration for solar roof tiles may be that there is no gap between the panels and the roof, perfectly integrated into the architectural design.

● Durability

Solar roof tiles have an expected life span of 20-25 years. Solar tiles are also easy to replace if they break or malfunction. There are many claims that solar roof tiles are stronger and more durable than standard tiles.

● Effectiveness

Because solar roof tiles are made of thin photovoltaic panels, they can be used in areas where it is difficult to install photovoltaic panels. However, the efficiency of these tiles still depends on shading, roof orientation, and solar exposure.

● Save Money

Solar roof tiles will reduce your energy bills and save you money. You might even have a chance to make money from the power company because your solar shingles send excess power back to the grid.

● Low Failure Rate

The operation of a photovoltaic power generation system has no mechanical rotating parts, no fuel, and water, and the power generation process is convenient and simple.

● Environmental Protection

Does not emit any substances, including greenhouse gases, does not produce vibration pollution, and does not produce radiation harmful to human health.

● Convenient Installation

Standard solar panels must be mounted on top of the roofing material, which usually means drilling holes into the roof. While solar roof tiles are part of the roof, you don't have to worry about drilling or installing equipment at the top of the roof.

● Easy Maintenance

Another key benefit of solar shingles is that they are light and relatively easy to repair and replace. If one or two are damaged, you can quickly replace new solar shingles or inactive shingles as needed.

The disadvantages of solar roof tiles

◎ High Initial Cost  

You'll save money in the long run, but as a newer technology, initial installation costs are high.

◎ Repair and Maintenance

Solar roof tile technology is still immature and it is still difficult to find qualified installers in most places, especially if you live outside a major city.

With solar shingles, your roof can keep you comfortable and safe and generate electricity. Manufacturers will continue to make more affordable and efficient solar shingles, so the future of solar products is definitely brighter.
