I got a great Enphase installation from Solar-Tec and Ian Christie was just great in sizing properly my system. I purchased my system and nobody else could beat the price. And Ian gave me an additional break when the local municipality was late in approving the project and the State of California credit had moved down one notch. The resulting system is performing at 102% of the maximum calculated by the federal government tools for my area, PVWatts( ), which simply says that the installation is just PERFECT, and maximizes the efficiency. You can see my system here: You should see description, photos, arrays, energy production and much more, including a complete history of energy production from day 1. Click on «System Details» on top left under the system name to see the additional data. I was able to generate a chart from that shows the current consumption vs. production, which at this time of year is between 65% and 85% in Redondo Beach. During summer that number exceeds 100% and I am pushing energy into the grid. I do have a LOT of computer equipment and 5 plasma displays, so my daily consumption has easily exceeded 30kWh per day. Having solar has taken me down from Tier 5 to Tier 1 with Southern California Edison, resulting in huge savings. I just switched from and older Mac Pro server(I have an home office) to the newer Mac Pro, and now I am able to push energy to the grid on a daily basis. As a result I will be able to pay back my solar system in less than 4 years. I did a LOT of research before selecting the best system and best company with Enphase and Solar-Tec.
