What is the difference between solar panels and solar tiles

What are Solar panels

Solar panels, also known as photovoltaic (PV) panels, have been a mature technology for many years and are common on south-facing rooftops across the country. However, the new trend of solar shingles (or solar roof shingles) is becoming a viable option for solar consumers. They have only recently been available to the public for home installation. So, if you can choose solar shingles with aesthetics, how do they differ from traditional solar panels? Bonada makes a comparison to help you choose the best solar panels for you.

What are solar shingles

Solar shingles, also known as solar roof shingles or photovoltaic shingles, are small solar panels designed to mimic and play the role of traditional roof shingles. They are a relatively new solar solution and are often considered building-integrated photovoltaics (BIPV). This means that the roof shingles can use the sun's energy to produce energy for your home.

solar panels vs solar shingles

Structural comparison:

The photovoltaic panel is installed on the roof tile. The photovoltaic and roof are two independent parts. The product has a single appearance and low aesthetics. And it will increase the load-bearing capacity of the roof, posing a safety hazard.

Photovoltaic shingles are innovatively designed using crystalline silicon photovoltaic technology and architectural tile structures, integrating photovoltaic and architectural properties. The entire roof is modularly installed, which can replace traditional cement and clay shingles and have the same lifespan as the building.

Comparison of applicable scenarios:

Photovoltaic panels are more suitable for flat roofs that pursue large power generation and have no other requirements for roof appearance, while photovoltaic shingles are more suitable for villa users who have higher requirements for roof waterproofing, integrity and safety.

Comparison of economic effects:

For the same 10kw installation cost, the brand clay tile roof (waterproof + insulation) is 500-700 yuan/square meter, the cost of photovoltaic panels for villas in Beijing and Shanghai is between 6W-6.5W, and the total installation cost is about 250,000 yuan.

The total cost of photovoltaic tile installation is calculated based on a 200-square-meter roof. The photovoltaic part increases the cost by 198-580/square meter, so the roof system + photovoltaic system ≈ 798-1180/square meter. The total installation cost is about 160,000 to 240,000 yuan.

So, if it were you, would you choose to install photovoltaic shingles or photovoltaic panels first? Whether solar shingles are right for you depends on the house situation, goals, and project budget. I believe that as solar roof shingles become more common, the price may drop, thus gaining wider favor.

Frequently Asked Questions about Photovoltaic Modules

Does poor grid power quality affect a photovoltaic power generation system?

A: Grid quality issues such as excessively high grid voltage and abnormal frequency will cause the inverter to shut down. The system will automatically recover after the grid is restored.

What are the environmental requirements for rooftop photovoltaic power generation system installation?

A: Large dust pollution sources, strong winds and sandstorms, and heavy smoke around the photovoltaic power generation system will affect sunlight utilization and result in reduced power generation.

Do fragile components need to be replaced immediately during scorching sun?

A: They cannot be replaced immediately. If replacement is necessary, it is recommended to be done in the morning or late afternoon. Contact the power station operation and maintenance personnel promptly for professional replacement.

Does the photovoltaic power generation system need to be disconnected during thunderstorms?

A: Distributed photovoltaic power generation systems are equipped with lightning protection devices, so disconnection is not necessary.

Will there be a power shortage in cold winter weather?

A: In winter, temperatures are lower and the duration of sunlight is shorter, so power generation is generally lower than in summer. This is normal.

Does damage to the surface of photovoltaic modules affect the modules?

A: Damage to the module surface will cause abnormal power generation and may lead to leakage.

How often do modules typically need to be cleaned? What precautions should be taken during cleaning?

A: Maintain components that require regular inspection according to the product supplier's instruction manual. Manual cleaning is generally not required in areas with heavy rainfall. Cleaning should be done approximately once a month during the non-rainy season.
CAUTION: Do not attempt to clean modules with broken glass or a perforated backsheet, as such modules pose a serious risk of electric shock.

Can I replace a damaged PV system component myself?

A: Replacement should not be done immediately during the scorching sun. If replacement is necessary, it is recommended to be done in the morning or late afternoon. Contact maintenance personnel promptly for professional replacement.

Will shadows from buildings, leaves, or even bird droppings obstructing the photovoltaic modules affect the power generation system?

A: If the modules are obstructed, the system's power generation efficiency will be reduced, and the power generation will be significantly less than that of an unobstructed system.
