SONNETEK CORP.
Solar Panels Design, Manufacturing & OEM
About Us
Sonnetek is a division of MMITEK Group. MMI has been in the business of designing, producing and selling solar panels, computer hardware and electronic products for large corporations since 1978. Our first factory was based in Taoyuan, Taiwan, in a small shop that primarily created tools to be used for stamping sheet metal. In 1981, due to MMI's popularity in the industry, MMI purchased a 288,000ft2 factory nearby to provide room for its growing business. In 1993, MMI's business had yet again outgrown its factory. However, due to increasing costs pressures from the market, MMI decided to open its new factory in ShenZhen, China. To support MMI's factories and to grow its channel market in the United States, MMI opened a warehouse and sales office in City of Industry, CA, in 1990. MMI quickly outgrew its humble beginnings in the United States and expanded into a 70,000ft2 facility in City of Industry. City of Industry is the heart of the computer hardware and electronic product industry in the United States and is convenient to all modes of transportation - ocean, trucking and rail.
Due to Solar panels business has continued to grow ,needed an avenue to support that growth. In addition, Sonnetek needed a means to better reach its customers and provide them with more solutions. Thus, in 2002, MMI opened SONNETEK DIVISION to sustain that growth and fulfill those needs. With regional distribution centers, an advanced e-commerce web site and a diverse line of products.

HOW SOLAR WORKS
Solar cells are made of thin layers of silicon. When sunlight strikes the cells, physical reactions release electrons, generating electric current. Individual cells are grouped together to form solar modules which, when installed on the roof or ground as a component of a complete solar system, generate electricity.
THE COMPONENTS THAT MAKE UP ONE SOLAR POWER SUPPLY SYSTEM
Solar power supply system is made up of solar panels, solar controller, batteries. If the output is AC 220V or 110V, it needs inverter.
THE ACTION OF EACH PART IS
SOLAR PANEL
It is the hard core of solar power supply system. Its action is changing radiating power into electric energy or keeping in battery, or driving loads.
SOLAR CONTROLLER
The action of controller is controlling running order of whole system. It can also avoid battery overcharging or over discharging. In some district, it has the action of temperature correction. Some other additive function such as light control switch、time control switch is selectable .
BATTERY
Commonly we use lead-acid battery. In micro-system we can also use nickel-hydrogen battery、nickel-cadmium battery or lithium battery. Its action is storing electric energy and releasing when need.
INVERTER
The output is 120VDC, 240VDC, 360VDC higher voltage in solar panel power supply.
In order to supply electric energy to electric equipment of 220VAC or other supply standard，it has to change DC current into AC current. So it needs DC-AC inverter.
