As conventional fossil-fuel energy sources such as oil, gas and coal continue to be depleted, it is important for us to find alternative solutions to meet our daily energy demands. As one of the most promising solutions, photovoltaic is becoming an established source of energy. Not only is solar energy clean and renewable, but it is also proven as a viable, reliable and fully commercialized solution. In a long term, photovoltaic would be a cost-effective energy enjoyed by all the human being in the world.

Why solar energy?

There are so many other alternative energies out there, so why
Solar?

Key Advantages over other Alternative Energy Technologies:

∙ Solar products are fully commercialized

∙ Solar is a renewable, clean energy source

∙ Solar is reliable and maintenance cheap or even free

∙ Solar does not require new or complex infrastructure

∙ Solar is a distributed form of energy generation

∙ Solar power generation coincides with peak energy demand

∙ Solar energy is attracting fund investing

∙ Solar manufacturing supply is well defined

∙ Solar shares a process improvement road map with the IC industry



What's the history of solar PV?



The first solar cell was created in 1883, but was only capable of
turning one to two percent of sunlight into electricity. The breakthrough in solar  cell technology came in 1954 when researchers at Bell Laboratories stumbled  across the photovoltaic properties of silicon while experimenting with new  transistor technologies.

Three years later, PV research began to develop anindependent solar  energy source for space technologies. Thanks to continuing research, modern commercial PV cells have improved efficiency to as high as nearly 19 percent. Historically PV cells have been used extensively in areas  that are not served by a power grid.  As PV prices have dropped & grid energy has become more expensive, PV systems are increasingly used in grid-tied applications.

How does solar power work?

A solar cell is a device made of semiconductor materials (such as
silicon) that converts the energy in sunlight into electricity. Solar cells are manufactured with a built-in electric field, so when sunlight strikes the cell, a portion of the light is absorbed by the semiconductor materials.   The solar energy knocks electrons loose from their atoms, allowing electrons to flow freely.

The built-in electric field forces electrons freed by light absorption to flow in a certain direction. This flow of electron generates electricity, which can be drawn off to power various objects. The conversion of sunlight    (photons) to electricity (voltage) is called the photovoltaic effect. In a PV system, these semiconductors are produced in the form of cells, which  are then assembled in a structural panel.

There are many different types of panels available, and each has its particular advantages. Depending on the amount of electricity needed,        these panels can then be connected in an array of any size to provide the electricity needed for a home, office, or larger facility. Solar cells are usually small and only produce a couple of watts of power.

To produce usable energy, many cells are strung together to make a module. Multiple modules are connected into an array,which are connected to a load (like a light bulb).      

Through the wiring the electrons have a chance to flow through the whole loop back to the layer that lost its electrons in the first place. The electric current, as this flow is called, has done its work, making light and heat in the light bulb.

How to design and install a suitable solar power system?



Starting point for the design of a PV system is the provision of the required amount of energy with predetermined reliability. Only in this way PV systems can be sized in the right way. Engineering, assembly and installation practices are performed according our high quality standards in
order to ensure proper operation whilst keeping maintenance to a minimum and reliability to a maximum.

The right match between the system components, including the load, is of paramount importance to compose a system that operates at the lowest possible costs. Maintenance requirements for PV systems are very low. Normally only once or twice a year a visit to the site is required to check all the system functions, to clean the solar modules and to top up the battery. (only in case a vented or open battery is used).

Proper maintenance will benefit the reliability and the life cycle costs of the PV system.

How to install solar modules for my home?



Before you contact MFS Solar, you will want to ask yourself  whether your panels will be lying flat on the roof or angled toward the light for maximum effect.

Other than solar panels, you also need MFS structures whose angle can be set according to your requirements. First off you will want to get the screws and mounts to attach to the roof to make sure it is safe, because safety should always be number one priority.

Once you have your supplies, which can be found online or at any hardware store, find the rafters in your roof using a stud finder and drill holes. You can use a laser or chalk line to make sure they are all in a straight line. Place the mounts over the holes. In here will go the rails the panels sit on. Once the rails are in place it would be smart to hot mop them to make sure they are mounted securely. Steel bolts will secure the rails to the posts you secure.

Now the hard part is done! The panels themselves must be installed flat and in a straight line. Once they are set you can connect them into an array. Finally you must run the conduit so it connects to the inverter on top of the roof. Congratulations, your solar panel energy system is now installed!



How to test my solar modules' power and performance?

MFS Solar offers flash test for all customers if required. We have professional flash test machine that can indicate power and performance of system.



What's the difference between monocrystalline and polycrystalline
silicon solar panels/modules?

Mono-crystalline panels/modules are slightly more efficient so panels constructed of them will collect more watt*hours per sq foot/meter (or panels of the same wattage rating will be slightly smaller when made from mono-crystalline cells). Some people also like the uniform color of mono-crystalline cells (instead of the "blue fractured look" of poly-crystalline panels).
