What research says

The 190 Watt photovoltaic module from Evergreen is from their Spruce series and is made for grid-tie systems. The reason this system gets Editor's Pick is because of the care taken by Evergreen during the manufacturing process to ensure a low environmental impact. The only gripe we have about it is the relatively short warranty. Online consumer comments tell us the Evergreen modules are tough and last a long time, so we wonder why the company doesn't provide a little more assurance in their warranty-length.

The Sharp PV module is the only one under 190 watts (it is 180-W) but it makes up for it with some great features, such as a 25-year warranty, and built-in bypass diodes. Sharp has a strong name in the industry but for the price we would go with a higher-output solar panel.

At 17.4 percent efficiency, the Sanyo is the most efficient photovoltaic module out of the the ones we reviewed. This is because of Sanyo's HIT (heterojunction with intrinsic thin layer) technology, which allows the module to obtain maximum power within a fixed space and a lower temperature de-rating. As the days get hotter, the Sanyo HIT technolgy allows these photovoltaics to produce more electricity than conventional crystalline silicon solar panels at the same temperature.

The Kyocera KC190GT is a very good solar panel for the price and works well in everything from small-scale residential solar power systems to mid-scale commercial projects. Kyocera uses newly developed treatment method processes multi-crystalline silicon cells in order to produce a surface texture that minimizes surface reflectance and maximizes output.

In Summary these are all great PV modules to own and would work very well with any grid-tie system. If you have an off-grid system, the Sharp might be your best bet. If you are tied to the grid, we suggest either the Evergreen or the Sanyo 190-Watt solar power PV modules. We chose the Evergreen because it was about $200 less than the Sanyo. However, the Sanyo might end up being less expensive in the long run. Remember - The more efficient your solar power system is, the faster it will pay for itself.

BP Solar seems to be making a big push in the market; do you know how its panels compare in solar cell efficiency?

jc said:

i'm not well-versed with the solar panel jargon. does this review apply to both commercial and residential solar panels? what about sunpower? i've been surfing the net and i've come across the brand several times.

Have Yingli polycrystalline modules been reviewed

Michael B said:

You say some are better for grid tie and others are better for off grid systems. What makes one better or worse?

anand said:

prices of the modules are about 5$ per watt,which is well above 1 - 1.2$ per watt of first solar

When did you write these reviews? In a fast-changing field, we need to know.

Dave, good point. This review is several years old now (circa 2008) so it would be a good time to do another comparison of 190-watt solar panels. I would gladly pay an expert writer to do this new review.

Rosie said:

Are these PV panels reviewed for the USA? I live in the UK and have heard that Mono-Crystalline panels are more suitable for the UK than Poly-Crystalline. Also does anyone know about the Caymax 195W paels. They are made in China, I believe.

Q6LMXP3 from Q-cells has an efficiency of 17.0 - 18.8%. The current reviews on this site are outdated.
