It has been a little over two years since California Solar installed the 27.54 kW system on my commercial building in Carlsbad, California. I’m only sorry I did not install this system sooner. To date we have offset more than $20,000 in energy costs. In connection with some other efficiencies I have added, we are virtually at “net zero” for my office. I wanted to thank you for demonstrating professionalism throughout the process. You identified durable and reliable equipment, assisted me in obtaining federal credits and have checked in to make sure the system continues to operate with maximum efficiency. I strongly believe that every commercial building should utilize its unused rooftop space to install solar. From a business perspective, I am converting unused space into a long-term revenue source that will yield me more than $3 for every dollar I spend over the next 20 years. From an environmental perspective, I have saved well over 47 tons of CO2 and planted the equivalent of 164 trees. At this rate, I will have effectively planted a small forest over the lifetime of this project.
Thank you again for overseeing this project. I strongly recommend California Solar to any prospective client.
