Suntech 250w – Suntech cells continue to outperform and are exceeding the industries expectations. 270w and 330w are now the common size replacing the 200w to 250w range. Same reliable manufacturer with 25 year warranty.  Remember that the 250w – 290w range are almost always 60 cell modules, which are not suitable for battery charging except with a MPPT controller.  In battery language, they are nominal 18v modules.  If you use a PWM charge controller with these modules,  you will harvest approximately half of the rated power.
