The best feature of this system for me personally was having my own control panel where I can monitor all aspects from start up time through shut down / turn off times as well with ease! It has also been very helpful being able update it myself instead going into their office every so often when something needs updating or changing out etc... My only complaint would be if you have more than one person using your solar power plant then there will need another login account setup which makes things difficult at first but once set everything runs smoothly without any problems like other companies do now days.. We are saving money by not paying monthly utilities bills plus we get our electricity back instantly unlike some others who take weeks before they realize how much extra charges were added onto what used too come across!!
