The Early Adopters are a young family with kids both parents are interested in science, technology and conservation. From the beginning they wanted to start off small and expand the system over time. After visiting the site, surveying the house, meeting the Early Adopters and discussing their goals. We proposed a system with Trina Panels and Enphase micro-inverters. Using the Enphase micro-inverters would allow the customer to expand the system overtime in an affordable way. After pricing the system the Early Adopters decided to start with 6 panels and 6 inverters. We then completed the design of the whole system and prepared the permit drawings. In this project it was important to account for system expansion this is why we made sure the appropriate electrical infrastructure was planned and specified in the drawings. After the system design and planning was complete we submitted the specs to Com Ed and the permit drawings to the local village.
The permit was approved a week later and the ComEd approval took 10 days. For this project the customer hired a local electrician ( Paxson Electric ) for all of the electrical work. I coordinated my installation crew with Paxson and the system was installed in 1 day. Since we used the Enphase Inverters the next day the Early Adopters and I were able to monitor the system performance from the internet. So far everything is working great.
Below is a series of installation pics and a pic of the enphase monitoring web page.

We started by laying out the array and installing the roof flashings.

Then the racking was assembled, the microinverters installed and panels laid out.

The wiring was checked and double checked.

The panels mounted on the roof.

There are some very interesting points outlined here, especially some specific ideas that must be put in place for the United States’ production/consumption of energy. With the Obama administration offering 2.3 billion dollars in subsidies, the United States still cannot compete with the rival companies in China. The subsidies in China are plentiful, and they range from free land to large amounts of cash for research and development, even though China’s energy consumption is growing faster than any other country. By far the most impressive fact is that Beijing aims to generate 20,000 megawatts by the year 2020!!
