Solar Loans - what is the tipping point?

There is a lot of news flow on investor interest on raising funds for solar loans, but not much attention has been paid to - what constitutes an ‘attractive interest rate’ to make homeowners ‘jump’ to make that solar investment.

Supply Side First

Lets focus on the resource side; the benchmark for raising ‘low cost’ institutional funds lies will be SolarCity’s…

The Next Generation of Solar Panels? V3 Solar’s Spin Cells

Solar panels have become more familiar to us in recent years. At one time you would have been hard pushed to find a set of solar panels on a roof near you. Now it is exceedingly common to find these panels adorning roofs all over your local area, even if you don’t yet have them.

Of course as with any other type of technology,…

What is and how we can use solar energy?

 Most of us know already that the price tag of electrical energy, fuel, natural gas, wood together with other energetics are continually increasing. For that base we must always ask ourselves can our house budget stand with so many expenses. Each single investment involves some amount of cash, however this isn't the end and besides investing every single single day by day or every year by year we pay for electrical bill, natural gas, wood, etc. Keep in mind that even with solar energy…

President Obama calls for a strategy "that relies less on foreign oil and more on American-made energy"

A strong commitment to the development of alternative energy has been made by President Barack Obama. In a recent radio address, the President called for a strategy "that relies less on foreign oil and more on American-made energy". These renewable energy sources, which include solar and wind power, will not only help wean the U.S. from fossil fuels, but create thousands of new American jobs. Solar training of these workers will be an important part in expanding alternative energy…

The five disadvantages of solar power

It's intermittent. Solar energy is only available when the sun is shining.

It's low efficiency. It requires large areas of land.

It's not completely free of environmental impact. Ultrapure polysilicon is now scarce.

It's high cost.

You must climb your roof to wash it off. Just ask Ed Begley, Jr.!

What leading edge developments should I be focusing on?

You woke up this morning full of vim and vigor, ready to tackle the world of home energy efficiency. Of course, your first dreamy thoughts were: is this major solar flare going to knockout electricity in the midwest power grid, and then, if Fermilab has found proof of the Higgs Boson, will I be able to fully explain the phenomena of convection and chimney effect to people? After your morning coffee, the reality check sets…

Solar Power Panel and the Pergola

Getting the Most out of Your Pergola, Think Solar Power Panel

by Don Ames,

Sitting in a meeting the other day, I was listening to a discussion on where to put half-a-million dollars worth of solar power panels. The discussion considered placing panels on roofs, on picnic shelters, and carports - it's not easy trying to find a place for a bunch of solar panels. After all, there are things to keep…

Willowside Rd., Day 2

I caught up with John Doe while he was on the way to work this morning, apologized for not getting back to him last night, and checked in about Tuesday of next week, April 12th, for his test-in Audit.  The weather forecast is for a perfect day: cool and clear, which should allow distinctive IR photos of air infiltration pathways during the blower door test.

I stopped in at Harmony Farms, my favorite farm & garden store, on Hwy 116 this afternoon to talk to Ali Ghorbani, who is… Continue

Solar Power Plants an Alternative to Nuclear Power Plants

Upon the earthquake and tsunami disaster in Japan on Thursday, March 14, 2011, nuclear power plants have shown to not have the capacity to withstand extremely powerful natural disasters. The earthquake and tsunami led to problems at three of the country's nuclear power plants, one of which remained a serious concern Monday as crews continued a seesaw battle to control a damaged nuclear reactor complex.

In Fukushima Prefecture, an explosion in a building housing the No. 3 reactor at the… Continue
