Top Solar Power Companies…

Want to know what are the top solar power companies in the world, or in the US? For a thorough look at solar power companies leading various solar power markets and holding various solar power records, check out our Solar Energy & Solar Power Facts page. However, for a look simply at the top solar module manufacturers based on annual production, the top solar developers, and the top residential & commercial solar power companies, check out this nearly full repost from Cost of Solar:

Top Solar Module Manufacturers

I’ve already taken a deep dive into solar panel efficiency leaders, so I’ll skip that today. The top solar module producers vary a bit depending on which market research firm you listen to, but here are a few rankings (quite similar) from two top cleantech market research companies, Solarbuzz and IHS:

Top Solar Power Companies

Clearly, as of the end of 2012, Yingli Green Energy (a China-based solar module company) and First Solar (a US-based thin-film solar module company) are leading when it comes to solar module production. Trina or Suntech, both Chinese companies, came in at #3. However, Suntech has gone bankrupt, so it will see a steep fall in the 2013 rankings. Other than First Solar, the only other US company on the two lists is SunPower. SunPower, unlike First Solar and most of the others on the list, produces very high-efficiency solar modules — the most efficient on the market. That makes it a leader for residential solar power systems, where higher efficiency helps to maximize limited rooftop space.

Top Solar Developers

When it comes to developing utility-scale solar projects, First Solar leads the pack (it’s a vertically integrated solar company), followed by US-based Juwi Solar and US-based SunEdison:

Top Residential & Commercial Solar Power Companies

In the US residential solar market, Sunrun, which pioneered solar leasing and PPAs for homeowners, claims the title of “#1 home solar company.” It currently provides such services in Arizona, California, Colorado, Connecticut, Hawaii, Maryland, Massachusetts, New Jersey, New York, Oregon, and Pennsylvania.

Meanwhile, SolarCity, which also provides such solar options for homeowners, claims the title of “#1 full-service solar provider.” It and Sunrun, as well as numerous other companies in this space, compete in the home solar market with very similar offerings. SolarCity also implements a lot of projects in the commercial and government arenas. SolarCity is in business in Arizona, California, Colorado, Connecticut, Delaware, Hawaii, Maryland, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Texas, Washington, and Washington D.C.

While about 75% of homeowners who have the choice between purchasing a system or leasing one decide to go with a solar lease, there are critics of this model who argue that a customer gets more out of buying a system than leasing one. However, it really depends on one’s priorities and preferences. If you get a quote from Cost of Solar, we can also call you and discuss your options so that you can decide which route is best for your situation and you.

There are actually thousands of solar installers across the US. Sometimes local installers can beat the offers provided by Sunrun and SolarCity, while sometimes those larger solar companies offer a better deal. It depends on many factors, such as the state you are in, the size and shape of your roof, the age of your roof , and so on. I think the best thing to do is talk to someone who can help you navigate the options in your area and get you the best deal for your needs.

    Could you send me a summary of the solar power companies leading a different segment of the solar market

    • Zachary Shahan

      Hello, sorry, not sure if i follow — which segment?

  • Stan

    The issues are rather complex. How does one compare with another? I just received a forty page (plus attachmnets) small print leasing contract offer from One Roof Energy Company of San Diego, and have seven days to accept or cancel. Were I to seek a compentitive bid, I don’t know if the time allows for such, wouldn’t know who else to contact for such a bid, and wouldn’t know what the key indicators are to compare, were I to contact another company to invite a competitive offer. Help!.
