More efficient solar kits is what Go Power keeps striving for. They are increasing their wattage from identical footprint panels almost across the board. For example, over the last few years, they have raised the wattage rating on their Overlander kit from 160 watts to a new panel that has 190 watts of power. More efficient solar kits is good news for the RV market because larger arrays can now sit atop units across the world. This allows for fast charging of battery banks.
This 30-watt increase in power can really make a difference in total watts in a large Go Power solar array. For example in an All-Electric 6 Solar Panel (AE-6) setup, a user gets about an extra 180 watts of solar charging power. That is almost like adding another panel.
There is talk of more efficient Go Power panels on the horizon, who knows where this will lead us when paired with better battery technologies. Maybe one day we can run our RV air conditioning on solar.
