What is a Solar Panel
Today, we live in the era when solar power is becoming a widespread energy source. First of all, the cost of solar panels has considerably decreased lately. Almost everyone now has the opportunity to buy them for home use as well as for trips, picnics, and traveling. Secondly, solar power is one of the cleanest and most reliable forms of renewable energy available today.
A solar panel is a set of cells joined together and enclosed in a frame. A solar cell, in turn, is a semiconductor device used to convert light energy into electrical power. In most cases, solar panels (or solar modules) serve as an additional source of power. In some applications, however, they can completely replace the main power supply. An important advantage of solar energy is that the amount of sunlight is highly predictable within a year. In spring and summer, for example, a solar panel receives more solar power than in autumn and winter. So, you can assess the amount of renewable energy produced by solar modules in advance. A pleasant addition is that unlike other alternative energy systems, installation of sun power solar panels is a piece of cake!

What Features to Compare
The first thing we'd like to draw your attention to when choosing the right solar panel is its type. Based on materials they are made of, solar panels are typically classified into monocrystalline, polycrystalline, and thin-film panels. If you're going to install solar modules in some limited space, you should choose a monocrystalline panel. Panels of this type are the most efficient and give more power from a certain roof area. Alternatively, if there is no limit on the working space and you can install more solar panels, it's reasonable to look at polycrystalline modules. These panels boast a good quality and excellent value for the money they cost. As for thin-film panels, they don't have a rigid frame and perfectly fit for installation on uneven surfaces. Thanks to their portability, they're a splendid choice for vacation, travel or fishing.
Having decided on the type of a solar panel, pay your attention to its performance. The most important issue is the solar conversion efficiency. Basically, the higher the efficiency, the more energy you get from your module. The second crucial indicator of performance is the power output. So, you should determine in advance what wattage you wish to get from your solar power system. The most popular solar panels provide on average from 100 to 200W, however, don't forget about tolerance which shows how this index varies. A temperature coefficient also affects the efficiency of a solar panel - it shows how it works with a temperature change and to what extent its power falls. Another important criterion to consider is its operation temperature range as this issue usually varies from region to region. It's worth mentioning that a lof of modern solar panels can work at a temperature from -40 to +90 °C. It allows using these panels in different geographic areas.
Don't forget to check the convenience of solar modules. Of course, size and weight are vital for a convenient installation. Since solar panels can be mounted not only on a house roof but on boats and trailers as well, you need to know the optimal dimensions of the panel. We'd also like to recommend users to select the maximally protected models covered with a thin layer of tempered glass. The advantage is that such panels are capable of withstanding severe weather conditions. Solar panels are usually produced in a corrosion-resistant frame made of aluminum. This reduces the weight of the structure and assures a long lifespan. However, if you plan to use solar panels while traveling, pay attention to the modules with a handle for comfortable carrying and folding legs for an easy installation.
KINGSOLAR Semi Flexible
Flexible Energy Source
Since most solar panels typically have a frame, they aren't easy to install on uneven surfaces. Thus, such modules should be placed at a certain angle which might negatively impact their effectiveness. However, there is an excellent solution to this issue. KINGSOLAR Semi Flexible Solar Panel is made of thin-film and durable material that makes it bendable (up to 30 degrees), therefore, it is easy to install the panel on an uneven roof of your truck, boat, or tent. Moreover, this solar panel doesn't need a special mount since it can be attached by adhesive tape, grommets, or Velcro. It allows you to use the module even for a short time and then easily remove it. Thanks to the semi-flexible design, a transportation and storage of the panel don't require significant efforts. And despite such capabilities, the efficiency of KINGSOLAR solar panel is up to 23.5%. Great!
Which Panels are Better?
The first major question which arises when choosing the right solar panel is which type of panel to select, monocrystalline or polycrystalline one. The main difference between them lies in the manufacturing process and materials they are made of. Monocrystalline solar panels have the highest efficiency rates of up to 22%. In comparison, the efficiency of polycrystalline panels is typically around 18%. The point is that monocrystalline panels are made out of the highest-grade silicone with a purification degree of up to 99,999%. The cost of producing panels of this type, however, is significantly higher than of the polycrystalline ones. Therefore, before making a purchase, decide whether the best performance or low cost of equipment is a top priority for you.

To get the most out of your solar panels, they must be directed precisely at the sun. In the northern hemisphere, for example, solar modules always should face true south. Many specialists also suggest that the panel is fixed or has a tilt that can be adjusted seasonally. It's necessary to add that some panels have active trackers that allow for automatic angle adjustment by tracking the movement of the sun throughout the day. However, such systems are known to be quite expensive.
Finally, if you're going to install a module on an even surface, you should leave enough space between the roof and the panel to ensure proper air circulation. It will prevent overheating and ensure more efficient work of the panel.

Since solar power highly depends on seasonal weather changes, it's reasonable to consider acquiring a wind generator. Basically, a wind turbine generator is an appliance that converts wind energy into electricity. When the turbine blades capture the wind and start moving, they spin a shaft that connects a rotor to a generator. More advanced models are equipped with sensors that measure the force and direction of the wind and turn a windmill in the right direction to get more energy. However, you should know that such systems aren't effective in the regions where windy weather is rare.
