We Have “Value for Solar,” but Should We Use It?

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/value-of-solar-use-it/

Earlier this year, Minnesota became the first state to formalize dozens of studies by adopting a “value of solar” formula that would fundamentally change the relationship between solar energy producers and their utility. It’s designed to have the utility accurately compensate solar energy producers for the value of solar electricity to the utility, its customers,… Continue reading

The Solar Opportunity

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/solar-opportunity/

The coming of solar grid parity offers an opportunity for millions of Americans to go solar affordably. But it also means a potential transformation, a democratization of an electricity system long dominated by centrally-controlled utilities and centralized ownership and production of electricity. When solar can undercut grid electricity prices, it may also undercut this 20th… Continue reading

Solar Costs and Grid Prices On a Collision Course

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/solar-costs-grid-prices-collision/

With the cost of solar continuing to fall rapidly (50% in the past five years) and electricity prices rising steadily, if slowly, the approach of solar grid parity is near. The following chart illustrates the trajectory of solar cost and electricity price, hinting at the coming intersection. 1 The chart compares the cost of a… Continue reading

Is Your Utility Ready? New Report Says Local Solar Could Power 10% of Country in 10 Years

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/utility-ready-report-local-solar-power-10-country-10-years/

Minneapolis, MN —Within a decade, more than 35 million buildings may be generating their own solar electricity (without subsidies) at prices lower than their utility offers, sufficient to power almost 10% of the country.

That’s the powerful headline from the Institute for Local Self-Reliance’s latest report, Commercial Rooftop Revolution. Despite the opportunity, utilities, regulators, and policy markers are largely unprepared for the surge of local solar power.

Commercial Rooftop Revolution

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/commercial-roofop-revolution/

Although only 0.1% of electricity is generated by solar power in 2012; within a decade, 300,000 MW of unsubsidized solar power will be at parity with retail electricity prices in most of the United States and more than 35 million buildings may be generating their own solar electricity sufficient to power almost 10% of the country.

Treasury Dept. Fingers Solarcity in Exploration of the Dark Underbelly of Solar Leasing

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/treasury-dept-fingers-solarcity-leasing/

A new government investigation of Solarcity on the eve of its initial public offering (IPO) may explain how solar leasing is fleecing federal taxpayers and making U.S. residential solar more expensive than in other countries. The Treasury Department inspector general is probing solar leasing company SolarCity (and others) for its use of “fair market value”… Continue reading

Why Are Residential PV Prices in Germany So Much Lower Than in the United States?

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/residential-pv-prices-germany-united-states/

Earlier this week, Lawrence Berkeley Labs released a marvelous comparison of residential PV costs in Germany and the United States, finally putting some detail to an enormous gulf in costs (nearly $3.00 per Watt).  The following chart (from page 35 of the presentation) shows the cost difference broken down into 9 categories, with ILSR’s addition… Continue reading

Why We Pay Double for Solar in America (But Won’t Forever)

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/why-pay-double-solar-america/

Update 12/21/12: Corrected chart.  Overhead and Sales Tax had been switched in the German data column. I often get flak when I publish research on the cost trajectory for solar (e.g. my Rooftop Revolution report estimates 100 million Americans reaching grid parity by 2021).  About half think I’m too conservative, and half think I’m too… Continue reading
