<div id="signature">10+ years ago I thought that Sunpower Solar wrote the best info. Their module technology was superior and the classic 327 module output was amazing in high temperature and also in cloudy skies. They were the first to have really good warranty for both workmanship and output over time.</div>

<div>I have little to say about the current crop of modules.<br />
