*UPDATE - Check out SRoeCo’s sortable, searchable Solar Panel Comparison Table.

This is a chart of the “Top 40 Most Efficient Solar Panels” available on the market today (11/01/09). All 40 most-efficient solar panels are from 2 companies: SunPower and Sanyo Electric. If you have limited space on your roof and budget is not a concern - these are the best solar panels on the market giving you the highest efficiency (greatest output) per area.

All of these solar modules are Monocrystalline clearly proving that this type of solar panel is the most efficient - more efficient than Polycrystalline and Thin Film. The panels listed at 290 kW and above all take up more than 17.5 square feet per panel. The solar panels rated at 230 kW and below take up less than 13.5 square feet. Read the rest of this entry »

Two great questions many people ask about solar panels are: “Which panels have the highest efficiency?” and, “Which solar PV panels are the best?”

This solar power panel comparison chart (from SRoeCo’s sortable, searchable Solar Panel Comparison Table) compares the output per square foot surface area of most 200 W model solar panels.  All of the modules on this chart are label rated at 200 Watts, which means in strict laboratory conditions, they produce the same output.  However, I have compared them based on their PTC ratings which is the rating given under realistic test conditions.  Sanyo, SunPower, Schuco, Kyocera, Suntech, GE, Evergreen, Canadian Solar, and Sharp are common solar panel manufacturers used by installers in the US.
