If you just started to build your solar power kit, it would be best to start with a 100W panel as it gives enough power to light some CFLs and also can power up a fan. It can be used to charge 12V batteries using a solar charge controller. Below are the top 3 100W panels available from different providers on Amazon. I will also list the reviews from the real buyers, so you can easily arrive at a conclusion to whether or not to purchase them.

Product Description
Ramsond solar panels use the most premium components and raw material. Ramsond solar panels use only ‘Grade A’ quality, high purity silicone cells. Ramsond does not incorporate used, rejected, refused or second-hand cells into its solar panels. Furthermore, Ramsond utilizes the most advanced technologies in the production of its panels, such as a fully automated, microprocessor guided, precision, robotic arms guided soldering process of the solar cells. The solar cells are coated with a blue nitride anti-reflection coating. This special coating process provides a uniform blue hue color and increases light absorption in all weather conditions. The encapsulation and lamination process used with Ramsond solar cells consists of a process that ensures true atmospheric vacuum and encapsulation of cells within lamination layers of High Ethylene Vinyl Acetate (High-EVA) and DuPontTM Tedlar®. Each panel is equipped with low-iron, patterned, tempered glass. The glass has been manufactured, again, through a proprietary process, providing up to 60% more strength, as compared to conventional photovoltaic (PV) glass. As a result, Ramsond panels are among the world’s strongest, with hail impact survival index rating of 25mm@80 km/h. This means the specialized PV glass of Ramsond panels can withstand hail size of 1+ inch, traveling at speeds of approximately 50 miles per hour. Ramsond solar panels are framed in heavy duty anodized extruded aluminum with drainage/mounting holes. The aluminum frame is specially produced for Ramsond solar panels and is designed to provide a perfect balance of technology, style and function. The combination of the advanced components and production techniques, along with Ramsond’s industry leading 25 Year Limited Power Warranty, make the Ramsond series of solar panels, among the most advanced and sought after PV modules in the world.

Product Description
Tired of all the noise and smell from your diesel generator? The Instapark SP-100W solar panel offers you a quiet, clean while carbon-free alternative. Capable of converting virtually unlimited solar energy into clean, green, most importantly, free electricity, this solar panel is made of high efficiency mono-crystalline solar cells embedded in transparent vinyl acetate behind tempered glass with heavy back sheet ensuring maintenance free performance. Unlike amorphous solar panels, which only last about 5-7 years of continuous use, mono-crystalline solar panels can still retain over 80% of efficiency even after 25 years of continuous use. Also, the mono-crystalline panels are much more efficient and thus smaller in size while producing higher wattage.
