Sorry Elon Musk, The Best Solar Power To Buy Doesn't Go On Your Roof
"For the last ten years, more and more people have been buying solar panels and installing them on their roofs. Companies like
Elon Musk’s SolarCity have flooded the market with cheap home solar deals, relying heavily on federal and state subsidies and creative loan agreements to keep prices low. In fact, just last week Mr. Musk revealed home solar panels that look like designer Italian shingles.
Over the years, these rooftop solar systems have been great buys, at least from an economic standpoint, for a lot of homeowners. But what many of these solar customers don’t realize is this: their rooftop solar purchases have likely been slowing, not increasing, the overall rate of solar penetration in this country, while also causing numerous cross-subsidies and distortions in power markets.
Fortunately, there is a new, more efficient (and more equitable) form of residential solar power hitting the market in many cities across the country. And it doesn’t require you to install solar panels on your roof.
It’s called shared (or community) solar. And in the right form, it’s likely to spread like wildfire. In fact, just last month, I signed my home up for my local utility’s shared solar program.
Here’s how it works. Instead of installing a small solar system on your roof, you sign a contract to pay for a portion of a large, utility-scale solar installation that the utility builds and operates for you somewhere else (in my case, on top of a big commercial building just outside of my hometown of Madison, Wisconsin). The utility still gets to earn a rate of return on the solar plant (as it would with any plant it owns and operates). So the utility is happy. I get greener, more efficient utility-scale solar power without having to put anything on my roof. "
