Switching To Solar Power, One Year Later
ThinSkin writes "Slashdot readers may recall Loyd Case's series of articles illustrating his experiences after switching to solar power for his family home. Loyd shared his one month update, a six month update, and now finally concludes his series after one year of solar power. Despite the $38,000 initial cost for the setup, Loyd is very optimistic after a $3,000 savings in one year, meaning that in about 12 years he will break even — though he suspects ten years is a better estimate considering other factors. Other reasons such as feeling 'green,' increasing the property value of his house, and the 'spousal acceptance factor' all support Loyd's decision on why he'd do it all over again if he had to." The article is spread annoyingly over multiple pages, like everything at the site, and the print version omits the graphs.
ROE is a much better way of calculating economics than "payback time," by the way

To all the people mocking his investment, your missing one thing. You do not know what the price of energy is going to do in the next few years. The guy in the article however is guaranteed a minimum amount of power each year from his solar panels at a rate he knows. (His initial investment / Life time of the panels). If the companies decide to hike the prices in two years time due a deterioration in Gulf politics for example, he is sheltered from its effects and lets be honest it's very unlikely the price is going to go down per kwh. He is also sheltered to a certain extent from the failure of the power network so if a situation does arise where there are rolling blackouts again, he knows he will a least have some electricity each day. One of the things that people constantly underestimate the price of is certainty.
And what long term investment would that be that reliably makes 5%? If he had invested that $38k in just about any stock or mutual fund in the past year, he'd have lost at least 30% of its value.
