The Renogy Solar Company and Renogy panels have a relatively short history. They have made a positive impact in the renewables industry during the time since they were introduced.

Undergraduate students in Louisiana started Renogy out of a University project. Then Louisiana's Business and Technology Center got behind them. Initially in 2014 Renogy sold solar products online through Amazon and eBay. Over the years since then, Renogy has developed this product into a steady local business. They are recognized in their home town for growing a local business.

Buying and installing 300W Renogy Solar 24 Volt Monocrystallne Panels is a leap towards having a solar home. It is an upgraded panel replacing the previous 280W model. These Renogy 300W solar panels move your home from an energy dependant house towards an energy production home. The Renogy 300W Panel was initially made for residential use. Most are used for grid-tied applications that require a multi-panel solar array. They are also suitable for small projects like cabins and sheds. As well, these panels now get sold for large commercial building installations.

This review notes that 300W Renogy Solar 24 Volt Monocrystalline Panels sell through Amazon as a 4 panels solar kit. This kit outputs 1200W of 24Volt power. You might see there are 300W Renogy RV Solar kits that are sold for mobile homes. If you want to see those 3 x 100W kits for RVs, click here.
