Pecan Street insights on panel orientation

DECA has long advocated policy makers consider changing their incentive programs to reflect the value of west, rather than south facing solar panels.  It’s good to see the folks at Pecan Street have quantified this intuitive  assessment. While the article at Greentech Media (http://www.greentechmedia.com/articles/read/are-solar-panels-facing-the-wrong-direction) seem to have done it somewhat wrong, the fact is “There’s no […]

The benefits of funding residential solar

While there are undoubtedly a great many benefits to installing solar on your own home, it’s becoming more and more apparent that there are real benefits to helping others do the same.

If you happen to live in California you should be taking note of the great incentives for heating water with sunlight instead of gas or electricity. These incentives aren’t small either: $2,175 is the “initial incentive level” if you are offsetting natural gas as a heating source. That’s a pretty great incentive for a system […]

As reported by New Zealand 3 News they are flipping the switches on their inverters right about now and giving up on their $1,000,000/year diesel habit that had been keeping […]

Heat Exchangers and Investments for Saving Energy

Perhaps one of the most under-appreciated sources for saving on one’s energy bill is a heat exchanger.   The basic idea of a heat exchanger is to take an existing source of heat (from air or water), concentrate it, and pass air over it to provide heat for a home.  Conveniently, they can work in […]

Contrary to popular belief it’s not always foggy in San Francisco and even with the fog residential and small commercial electricity producers can make quite a few Watts. […]
