And then came the 21st century! Each day opening with a new creation, something more advanced, something better than its predecessor. And every day, in 21st century, the successor becomes the predecessor. There is competition for almost everything, be it a pair of shoes or cars. And solar panels are also the participants of this race.

Solar panels are composed of photovoltaic cells which, using sunlight, generate electricity in an environmentally friendly way. Photovoltaic (PV) cells are made of semiconductors such as lead or silicon. There is no such claims that “This is the best solar panel” since the ones that are available are similar, but we can differentiate between them using a few key factors. Before reviewing the solar panels individually, let us discuss the key factors. The crucial and deciding factor for a solar panel is its efficiency. And as we live in a world of competition, there is something better and new in the market every day, and the main focus of the manufactures is to increase the efficiency. Many of the panels are rigid yet delicate. They can easily be broken down by a flying bird, and once this happens, the entire system might as well be considered futile. Hence, flexibility is second to efficiency on the list. This is because a panel that is not stiff will not be ruptured, and hence the flow of the charge inside the panel will not be disrupted. Third on the list is something we all dread: cost. If the panel is extremely pricey then it would only be seen in an extremely small number of houses of people who are extremely rich.

Sanyo solar panels

Price: $1195

These are one of the most efficient solar panels with the efficiency of 17.4 percent and 190 watt photovoltaic modules. This efficiency might sound less but as far as the others go, they have an average of 10 percent. The secret of its excellent efficiency is HIT technology. As a result, the solar cells can absorb the maximum of sunlight within their allotted space, and the de-rating is quite less in terms of temperature. What this means is temperature is directly proportional to the amount of electricity generated — the higher the temperature, the more electricity. The delicate silicon layer prevents the loss of electrons. Since these panels are efficient, the work can be done by a small number of panels, hence you save money, and there is no additional trouble of planting a bundle.

Kyocera

Price: $1085

Kyocera panels are durable, require almost no maintenance and have an efficiency of 15 percent. They are optimum to charge batteries which can then be used for cars, homes and various other commercial and consumer applications. They come with warranty of 20 years, and a power output warranty of 25 years, and is also somewhat cheaper than its rival models. The photovoltaic cells on this panel have been surrounded by extremely tough glass and a PVF back sheet which is attached to an EVA pottant. To make the installation easier, and the panel more durable, the entire sheet is established on a charged aluminum structure. The new “d.Blue” model uses an entirely new technology to make the absorbent layer of solar panel. To prevent reflection and maximize efficiency, the crystalline appearing silicon cells have been used. It is also classic to be installed on any kind of building, whether its is a small sector of a community or for urban style planning. Moreover, the unique color of this solar panel is camouflaged when installed in a building. These models are available in various power outputs.

Evergreen solar panels

Price: $1079

These exceptional solar panels have a 5 watt power resilience. They have a condensed glass which minimizes the reflection, and compared to other solar panels, this one gives the temperature ratings over 90 percent. Not only does it come with a power warranty of 25 years, it has a 1 year energy payback too. The solar cells have no traces of lead on them, which makes it environmentally friendly and its packaging could be used again and again. It has longer cables, with no traces of noble gases, to connect to panels over a long distance, and is resistant to strong winds. Also, there are various outlets of Evergreen that keep a check on the power output and the electricity that is generated, to ensure maximum customer satisfaction. Evergreen solar panels are created in way to be reliable, and they can be regarded as the most ‘green’ of all solar panels. The maximum power out of these panels is 180 watts and they can weigh as less as forty pounds.

Everstep

This is a 18 Watt portable folding solar panel. One of the foremost qualities of this solar panel is its folding ability and its weight, 2 kg, which makes it easy to carry around. All the attached parts of this panel are removable, hence can be fixed by the owner. This panel comes with cables so not only can you charge batteries you can also attach to it other electronic devices. Its ability to trap energy allows it to be used even when the sun is not present. Not only is it durable but is composed of solar cells that are most efficient. In addition, it is weather proof and a special device has been attached to it that prevents electricity in flowing backwards.
