The late Howard Zinn's book, "A People's History of the United States", will help you understand US history. It also helps place current political and social threads into the context of history. Highly recommended.

David A's Solar Power

Since electic rates continue to rise and recent years have seen brownouts, many Californians have installed some solar panels to reduce our costs and to aid everyone by providing extra power when it's most needed: during hot sunny days.

Over 230,000 homes in California have solar panels generating electricity.

According to a February 2015 Washington Post, investment by individuals and companies in US Solar/Wind energy production was 389 billion dollars over the years 2007-2014.

SunRun installed our solar plant. Sunrun seemed a little...disorganized during 2015. We don't expect to need any service for 10-13 years, so lets hope they fix their internal issues.

We have twenty eight panels installed. Eighteen facing slightly south of directly west, Ten facing slightly east of directly south.

We watch our power use and generation using The Energy Detective TED 5000 inductive couplers and the associated wall-wart computer which provides a web server on our home network with all the power data. It can produce nice reports with just your browser on your home network, but I added my own software to make my own reports and to ensure the data is all captured on my systems (not relying on the wall-wart from TED to keep the historic data safe).

From examination of SunRun's historical data we were generating a maximum of about 20KwH per day in the summer of 2014 with the 18 panels installed then.

On a sunny day we generally generate 37 KwH. Here are some of the 5 highest recorded Kwh generation days so far. Five pine trees died in 2016 and one eucalyptus was dangerously large. Getting rid of those trees has lead to the first instance of generating over 40KwH in one day and by July 20, 2016...more!

269 Kwh: Lowest monthly generation. December 2014.

1076 Kwh: Highest monthly generation. August 2015.

Most of the 2014-2015 winter was just above 500Kwh per month.
