Secrets of Big Solar VS Small; Viability Comparison Between Large and Small Solar Panels

When solar panels first became available to the mass market their wattage rating was fairly small. Around 2009 a large panel was 185 watts but as time went by, the size of the panels steadily increased.

Within the commercial solar renewable energy sphere panels of around 450 watts seem to be the most popular but currently, there is a shortage due to high demand and other factors.

This presentation will look at the viability of using a lower wattage panel, say 370 - 380 on the assumption that the $cost/watt is lower than the larger panels.

Enjoy!

If there are 2 companies and both are giving me a 10kw system. One uses smaller panels but more in number and the other is using bigger panels (producing more watts) and obviously less panels, does it matter which is better? Ty
