Solar Atta Chakki
A solar atta chakki is a flour mill powered entirely by electricity harnessed from sunlight. The main components that make a solar-powered flour mill work efficiently include:
Flour Mill – The grinding unit that processes grains into flour.
Motor – Drives the mill for smooth and consistent operation.
Solar Panels – Capture sunlight and convert it into electricity.
Solar Drive / VFD Drive – Controls motor speed and ensures energy-efficient performance.
Solar Panel Stand – Provides stable support and optimal positioning for maximum sunlight exposure.
Wiring – Connects all components to deliver power safely and efficiently.
The Flour Mill
The flour mill serves as the core component of the plant. It is recommended to install a mill with a minimum diameter of 20 inches, enabling a daily production of 10–15 quintals of flour. This setup can generate a daily profit ranging from ₹2,000 to ₹2,500.
The Motor
The motor is the second key component of a solar-powered flour mill. A 10-horsepower motor is ideal for operating a 20- to 24-inch flour mill efficiently. It is important to choose a high-quality, reliable motor—like the ones we provide—for optimal performance. When paired with solar panels, a motor designed for minimal jerk load delivers smooth and consistent operation.
The Solar Drive or VFD Drive
The fourth component is the solar VFD drive, also called the solar drive. Its main purpose is to convert the DC electricity generated by your solar panels into AC power that can run your motor. When selecting a solar drive, it’s important to choose a high-quality unit—like the ones we offer—and ensure that its capacity exceeds the horsepower of your existing motor. For example, if your mill’s motor is rated at 10 horsepower, you should use a 15-horsepower solar drive. Using a drive that is too small can cause excessive turbulence, preventing the motor from shutting off properly.
Solar Atta Chakki Panel
The solar panel for a solar atta chakki is the most significant investment in a solar flour mill. It generates the electricity required to power your grain mill efficiently. Solar panels are available in various types, including polycrystalline, monocrystalline, mono-PERC, and bifacial. When selecting a solar panel, it’s important to choose a technology that delivers maximum power output throughout the year.
For most users, a mono-PERC solar panel is the ideal choice. It is cost-effective, low-maintenance, and provides consistent electricity generation. While bifacial solar panels—which produce power from both sides—are an option, mono-PERC panels are generally preferred because they are easier to install and do not significantly increase costs. Although bifacial panels offer long-term benefits, their higher upfront cost makes them less attractive for most customers.
When sizing your solar system, ensure your panels match the motor’s horsepower. For example:
Use 10 kW panels with a 7.5 HP motor , Use 12 kW panels with a 10 HP motor
This ensures that your grain mill operates efficiently, delivering consistent flour output regardless of sunlight availability.
Solar Panel Stand
The solar panel mounting framework, also known as the solar panel stand, holds the fifth position in importance. This component plays a vital role in the efficiency and output of your solar power plant. Improper installation—either in orientation or tilt—can prevent your system from reaching its full potential, resulting in unnecessary energy loss and reduced returns. To maximize power generation, solar panels should always face south and be installed at the correct angle, enabling your plant to produce more energy using fewer panels.
