Rationalize your increasing electrical costs
We have a reason to accept our increasing costs of electricity. The Badger Mountain Winery brought design capacity of 33 kW of solar photo-voltaic energy online in September of 2011 (http://tinyurl.com/73cjtau). To date (6/11) and with our current approaching maximum solar input (June 21), 28.1 MWhr of electricity have been generated for a direct cost avoidance of $1967 at 7 cents per kWh, something south of 200 bottles of wine. At this rate, we only need 79 years to pay down society’s $200,000 investment (USDA grant 25%, 30% tax deduction, one year full depreciation). But with increasing electrical costs, we will benefit a shortened ROI time, maybe even approaching the 25 year life expectancy and 20% capacity loss (http://tinyurl.com/3tmhu3t). Based on solar energy per US Army 30 year data for Yakima (http://tinyurl.com/7rnva84), the average output is about 7% of theoretical. See the performance at http://tinyurl.com/893uu7n.
