The Time to Go Solar is Now

The high temperatures in the Inland Empire make it an ideal place to go solar. Thanks to the high temperatures and sunny days, solar panels are being installed in residential and business areas at a staggering rate. In fact, Inland Empire solar power installations are leading California in growth, increasing solar power production over 600% in the last few years. Semper Solaris is ready to help you join your neighbors in capitalizing on the hours of sun you receive daily. Instead of sending your money to the utility company every month you can instead control your own energy production by installing solar panels on your home. Right now, your utilities agency is saving thousands of dollars a year by selling you solar energy. Semper Solaris will help pass these savings on to you, giving you the path to financial freedom for years to come.
