More Solar Panels

In January of 2009 we had 16 Solar Panels installed by Solar Works on the roof of our house. It cost about $25,000, and the only reason we were able to afford the panels was because of tax credits: 30% Federal and 50% Louisiana State (the highest in the country I believe). Here is a picture from Google Maps showing the panels:

We were very pleased with their production, so in April of this year we added 18 more panels, maxing out our roof.
Here are the 20 panels on the NW side:

Here are the 14 panels on the SE side:

Using the Enlighten system from Enphase Energy, we can monitor the production of the entire system and any one panel. Here is what is taking place right now as I type this:

Right now they are producing 5.12 kWh. Each panel is producing somewhere between 142 to 159 watts. We have a reversible meter from Entergy so right now we are selling electricity to the company, and later, when it's dark, we'll be buying watts back.

The 18 newest panels cost just under $30,000, so the entire system of 34 panels cost $55,000. However, after the 2011 tax credits, we'll have invested just 20% of that, or $11,000. With the energy savings, the system, we hope, will pay for itself in five to ten years.
