What is a Smartflower?

A Smartflower is a self-contained solar panel system designed in Austria that opens and follows the sun like a sunflower to maximize solar energy production throughout the day. The unique design was first developed around 2008 by an Austrian startup company called Smartflower Energy Technology GmbH (Smartflower).

The Smartflower consists of 12 unfolding solar panels in a biomimetic “petal” design that sits atop a centralized pole. The solar panels are attached to metal arms that extend out from the pole. In the morning, motors and gears slowly rotate the panels to an east-facing direction to soak up the morning light. As the sun moves across the sky during the day, sensors and a tracking algorithm automatically adjust the angle of the panels so they are always directly facing the sun. At night, the panels fold up into a compact bud shape for protection. This sun-tracking system allows the Smartflower to generate up to 40% more power than fixed rooftop solar panels over the course of a year.

The entire structure is self-contained and pre-assembled. It can be installed in just a few hours by anchoring the pole in the ground at a site. The Smartflower connects to the utility grid or a battery system to deliver renewable solar energy. It is designed to withstand wind speeds up to 130 mph when fully folded up.

How a Smartflower Creates Electricity

A Smartflower uses photovoltaic solar panels to convert sunlight into electricity. The process works like this:

Sunlight hits the solar cells made of semiconducting materials like silicon.
Photons from the sunlight knock electrons loose in the solar cells.
The flow of these electrons generates an electric current.

Inverters convert the DC output into usable AC electricity.

The key parts of a Smartflower that generate electricity are:

Solar panels – 12 petal-shaped panels made of monocrystalline silicon solar cells.

Inverters – located in the center column to convert DC to AC current.
Batteries – Lithium-ion batteries to store excess electricity.

As the Smartflower tracks the sun, the solar panels maintain the optimal angle to maximize electricity generation from sun exposure. This solar photovoltaic process converts clean, renewable solar energy into usable electricity for homes and businesses.

Power Output of a Single Smartflower

The peak power output of a single Smartflower solar panel system is 2.5 kilowatts (kW). This refers to the maximum amount of electricity that can be generated in ideal sunny conditions when the panels are pointed directly at the sun.

According to Solar.com, the average annual energy output of a Smartflower ranges from 3,800-6,200 kilowatt-hours (kWh). This factors in reduced sunlight on cloudier days as well as the movement of the sun throughout the year. On average, a single Smartflower can generate enough electricity to power a typical home. However, actual output depends on location, sun exposure, and local weather patterns.

Factors That Affect Power Generation

There are several key factors that impact the amount of power a Smartflower solar system can generate:

Sunlight Intensity

The intensity of sunlight directly affects solar power output. Areas that receive more direct sunlight per day and have fewer cloudy days will generate more power from the Smartflower. According to the manufacturer, the ideal solar irradiation level for maximum output is 1,700 kWh/m2 per year ^[1].

Temperature

Ambient temperature also plays a role. Solar panels become less efficient as temperatures rise. Cooler environments allow solar panels to operate at higher efficiencies. The Smartflower is engineered to withstand temperatures from -22°F to 122°F (-30°C to 50°C) ^[1].

Geographic Location

Location impacts sunlight intensity and temperature. According to Smartflower, the system generates the most energy in the American southwest where sunlight levels are highest. Output is lower in northern latitudes. Ideal locations have limited storms, cloud cover, and air pollution ^[2].

Applications and Use Cases

The Smartflower has several main applications and use cases that make it an attractive solar option for homeowners, businesses, and remote locations:

Off-Grid Residential

The Smartflower is a great option for off-grid homes looking to go solar. According to https://smartflower.com/commercial/, the Smartflower can provide 100% of the electricity needs for an energy efficient off-grid home. With battery storage, the system can provide continuous power day and night. The Smartflower’s all-in-one integrated design makes it ideal for isolated residential settings.

Grid-Tied Residential

For homes connected to the electric grid, the Smartflower offers a turnkey solar system to reduce electricity bills. As a grid-tied system, excess electricity produced during the day feeds back into the grid, spinning the home’s electricity meter backwards. According to https://www.cnet.com/home/energy-and-utilities/smartflower-solar-review-beautiful-solar-sculpture/, the Smartflower can produce enough solar energy to zero out monthly electricity bills.

Commercial Installations

The Smartflower is also used to power businesses and provide solar energy to commercial sites. The modular, scalable design allows multiple Smartflowers to be installed together on commercial properties. According to https://smartflower.com/products/, the eye-catching solar flowers can attract customers and showcase a business’s sustainability practices. Ideal commercial uses include office buildings, retail stores, schools, hotels and more.

Costs and Financials

The upfront cost of a Smartflower system is substantial compared to traditional solar panels. According to Solar.com, the average price ranges from $25,000 to $30,000 before incentives and tax credits. CNET reports the basic 2.5 kW Smartflower system costs $39,950 plus shipping and installation, coming out to around $10 per watt.

Operating costs are low since there are no moving parts and minimal maintenance required. The panels and equipment come with 10-25 year warranties as well. Electricity costs from a Smartflower work out to $0.10-0.15 per kWh according to SolarReviews, which is less than the average utility rate of $0.14 per kWh.

While Smartflower has a higher upfront investment than fixed tilt solar panels, its increased efficiency and energy production provide quicker payback and lower lifetime costs per kWh generated.

Comparisons to Traditional Solar Panels

The Smartflower has some notable advantages compared to traditional solar panels:

It’s an all-in-one system that’s easy to install. Traditional solar panels require separate inverters, wiring, and racking.
The Smartflower tracker follows the sun for optimal solar production. Fixed rooftop panels produce less energy overall. (1)
With its integrated design, the Smartflower takes up less space than a comparably sized rooftop array.

The unique, high-tech appearance makes a visual statement. Traditional panels tend to look utilitarian.

However, the Smartflower also has some limitations versus rooftop solar:

It produces less total power for the price. A similarly priced rooftop system would generate more electricity. (2)

As a ground mount, it may not be allowed in some neighborhoods or require permits. Rooftop panels generally don’t have restrictions.
It requires an open, sunny location with no obstructions. Rooftop systems can work on any sunny roof.
It’s still a new product with limited long-term reliability data compared to traditional panels.

Overall, the Smartflower offers unique advantages but higher costs per watt. It’s best for homeowners who want a stylish, automated system and have the right site conditions.

Environmental Benefits

The Smartflower provides significant environmental benefits by generating clean, renewable solar energy instead of relying on fossil fuels like coal and natural gas.
