Solara Ultra Aluminum-Framed Glass Panels with genuine high-grade SunPower Cells

Solara "Ultra" Panels, with SunPower® 22.5% Efficient Back-Contact Cells
These panels have the highest grade SunPower® back-contact cells, and are available in guaranteed minimum 120 watt and 150 watt sizes. The electrical connections are made on the underside of the monocrystalline silicon cells, leaving the upper surfaces completely free of the metallic "collectors" seen on other panels. This results in the entire upper cell surface being free for solar collection, and an industry-best cell efficiency of over 22% where typical regular cell efficiencies are 17%-18%. Consequently, the Solara Ultra Back-Contact panels give more power from a smaller panel size. Multiple-panel installations in particular benefit from a greatly increased power output compared to that produced by a comparable number of similar sized regular panels. The high cell counts ensure that an adequate charging voltage is always available, even in extreme elevated temperatures. Current models have an all-black appearance, with a rugged black anodized aluminum frame that is designed and constructed with high torsional resistance and to stand up to extremes of temperatures and the harsh marine environment. Matching black ABS Mounts are available. Warranty is 5 years on construction and 26 years on output when used in a marine installation.
Solara Ultra panels contain only genuine high-grade SunPower® cells. SunPower® back-contact solar cells are currently the highest efficiency cells available for use in everyday applications at 22%+ efficiency, but are expensive and difficult to purchase. Genuine high-grade SunPower® cells are only sold to known purchasers in a few select markets, and significant quantities must be purchased to ensure a workable price. It has recently come to light that some back-contact cells, originally made by SunPower® but rejected due to poor quality, have found their way on to secondary markets and into panels originating primarily from China. These reject cells cannot carry the SunPower® name due to the poor quality, although some promotional material we’ve seen brazenly disregards this fact. Be wary of any solar panel with back-contact cells that does not explicitly make reference to the cells as being genuine high-grade SunPower® cells.
