Selecting a good solar panel/cell is a tedious task requiring a lot of considerations. Understanding solar panel and how it works will greatly help in answering the question.
Solar energy begins with the sun. Solar panels, also known as photovoltaics, 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 elecrical loads. Light from the sun is a renewable energy resource which provides clean energy, produced by solar panels.
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 panel systems.
While technologies are constantly evolving toward higher efficiencies, the most effective cells for low cost electrical production are not necessarily those with the highest efficiency, but those with a balance between low-cost production and efficiency high enough to minimize area-related balance of systems cost. Those companies with large scale manufacturing technology for coating inexpensive substrates may, in fact, ultimately be the lowest cost net electricity producers, even with cell efficiencies that are lower than those of single-crystal technologies. Solar cells are manufactured primarily in Japan, Germany, USA, and China, though numerous other nations have or are acquiring significant solar cell production capacity.
