Solar Panel

What Is A Solar Panel ?

Solar energy begins with the sun. Solar panels (also known as "PV panels") are used to convert light from the sun, which is composed of particles of energy called "photons", into electricity that can be used to power electrical loads. Solar panels can be used for a wide variety of applications including remote power systems for cabins, telecommunications equipment, remote sensing, and of course for the production of electricity by residential and commercial solar electric systems.

How Do Solar Panels Work ?

Solar panels collect clean renewable energy in the form of sunlight and convert that light into electricity which can then be used to provide power for electrical loads. Solar panels are comprised of several individual solar cells which are themselves composed of layers of silicon, phosphorous (which provides the negative charge), and boron (which provides the positive charge). Solar panels absorb the photons and in doing so initiate an electric current. The resulting energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into the electric field generated by the solar cells which then pull these free electrons into a directional current. This entire process is known as the Photovoltaic Effect. An average home has more than enough roof area for the necessary number of solar panels to produce enough solar electricrity to supply all of its power needs excess electricity generated goes onto the main power grid, paying off in electricity use at night.

In a well-balanced grid-connected configuration, a solar array generates power during the day that is then used in the home at night. Net metering programs allow solar generator owners to get paid if their system produces more power than what is needed in the home. In off-grid solar applications, a battery bank, charge controller, and in most cases, an inverter are necessary components. The solar array sends Direct Current (DC) electricity through the charge controller to the battery bank. The power is then drawn from the battery bank to the inverter, which converts the DC current into Alternating Current (AC) that can be used for non-DC appliances. Assisted by an inverter, solar panel arrays can be sized to meet the most demanding electrical load requirements. The AC current can be used to power loads in homes or commercial buildings, recreational vehicles and boats, remote cabins, cottages, or homes, remote traffic controls, telecommunications equipment, oil and gas flow monitoring, RTU, SCADA, and much more.

The Benefits of Solar Panels

Using solar panels is a very practical way to produce electricity for many applications. The obvious would have to be off-grid living. Living off-grid means living in a location that is not serviced by the main electric utility grid. Remote homes and cabins benefit nicely from solar power systems. No longer is it necessary to pay huge fees for the installation of electric utility poles and cabling from the nearest main grid access point. A solar electric system is potentially less expensive and can provide power for upwards of three decades if properly maintained.

Besides the fact that solar panels make it possible to live off-grid, perhaps the greatest benefit that you would enjoy from the use of solar power is that it is both a clean and a renewable source of energy. With the advent of global climate change, it has become more important that we do whatever we can to reduce the pressure on our atmosphere from the emission of greenhouse gases. Solar panels have no moving parts and require little maintenance. They are ruggedly built and last for decades when porperly maintained.

Last, but not least, of the benefits of solar panels and solar power is that, once a system has paid for its initial installation costs, the electricity it produces for the remainder of the system's lifespan, which could be as much as 15-20 years depending on the quality of the system, is absolutely free! For grid-tie solar power system owners, the benefits begin from the moment the system comes online, potentially eliminating monthy electric bills or, and this is the best part, actually earning the system's owner additional income from the electric company. How? If you use less power than your solar electric system produces, that excess power can be sold, sometimes at a premium, to your electric utility company!

There are many other applications and benefits of using solar panels to generate your electricity needs - too many to list here. But as you browse our website, you'll gain a good general knowledge of just how versatile and convenient solar power can be.

KSUNsolar Flexible Solar Panel

There different features of flexible solar panel, which makes it a great advantage over conventional solar panels.


KSUNsolar semi-flexible solar panel, or flexible solar panel are mostly made by ETFE surface, the raw material is from Japan. Solar cell is either from SunPower Maxeon cells or conventional monocrystalline solar cells, all with cell efficiency high from 20.40% to 23.70%.

KSUN S-series flexible is more resilient and thinner as the cell is from SunPower and backsheet is TPT, it leads the highest efficiency range of solar panels.Now power ranges from 7W-150W.

KSUN P-series use PCB backsheet, it can customize a lot of panels, like small ones 5W-150W, the conventional cells can cut into any possible small size, like bike-sharing small panels 5W. KSUNsolar gains a lot of experience producing KSUN P-series for last years, as we produces a lot of bike-sharing for leading brand in China, like Mobike, OFO etc.

For both ranges, we share similar producing lines, using laser cutting to make colourful design, shape, size, power, voltage. small KSUN S-series or P-series panels for backpack, mailing box, RV rooftop, marine, camping, outdoor, motohomes etc. All outdoor solar use or mobile solar use.

Portable Solar Panel & Foldable Solar Panel kits & systems

Portable foldable solar charging systems are available from 40w up to 200w. These portable foldable panels are a great way to maximise storage capacity of your RV or garage. They can be stored for extended periods of time and are easily deployed when the extra power is required for vacations or emergency backup power.

Complete and ready to use!

When you arrive at your destination, the set up process takes less than 5 minutes. Unpack the bag/case, unfold the panels, adjust the tilt legs, set on the ground in a sunny location pointing south, and finally connect the wires to your battery.

KSUNsolar is a professional manufacturer that has a great portable foldable solar panel products and we have summarized the main features to help our customers choose the best model for their portable solar panel needs. 

KSUNsolar folding kits feature monocrystalline / polycrystalline solar panel technology, are ground mounted, have adjustable tilt legs for optimum tilt angle, have a built in charge controller (without it for optional), 16t.lead wire with battery clips for easy hook up, and can be folded up and stored safely in a padded carrying bag. Warranty is 1 year on workmanship and 20 years on power output. ( solar cells from Germany)

Portable solar panels are a convenient source of power when outdoors

To use the portable solar panels just place them in the sun and connect the cable from the regulator to a 12 volt battery. The solar regulator will ensure the battery is not overcharged all you need is the sun to produce clean and free solar energy.
Portable solar panels from 40 watts up to 200 watts

There are many sizes to choose from, you can enjoy the convenience of solar power when travelling and camping, so instead of attaching a solar panel to roof of your boat or RV where it is vulnerable to damage and theft, choose from our range of portable folding solar panels.

They all use good quality solar modules and have an attached solar regulator including cables and battery clamps.
Whether you need a powerful 200W portable solar panel for the RV/ emergency back up or a compact 40W solar kit complete with carry bag and regulator you will find the size to meet your needs.

Tips for choosing a portable foldable solar panel kit

Portable foldable solar panel kits provide 12 volt power for charging 12 volt batteries. They are made up of two 12V solar panels that are hinged together so they can be folded together when not in use. They have hinged legs attached to the back of the solar panels as well as a small solar regulator with connected power cables and battery clamps. the complete portable solar panel kit is held in a carry bag or case.
