Big changes are pushing solar into the mainstream. Elon Musk's SolarCity gave the industry a huge boost when it issued $54 million in bonds backed by income from installed distributed solar systems. This financing deal is critical because it means that the industry will have access to the $1.2 trillion U.S. asset backed bond market. With the potential amount of U.S. commercial and residential solar at real grid parity expected to grow by 22.6 gigawatts (GW) in 2014, solar is in for another big growth year.

Growth, growth and more growth
SolarCity installs solar panels on the roofs of commercial and residential customers. In states like California where electricity is expensive and there is lots of sunshine it has not been hard to find new customers. The company expects to install 278 megawatts (MW) in 2013, 121 MW more than it installed in 2012. This growth directory is expected to continue on through 2014.

Elon's baby is also getting into the energy storage business. To decrease demand charges consumers can purchase the new SolarCity DemandLogic system. The device stores energy and releases it during times of peak demand, allowing a business to save money and put less stress on the grid.

Don't expect SolarCity to make money anytime soon, but it is on a strong growth path. As traditional electricity prices continue to rise solar energy becomes more attractive. With better access to the capital markets SolarCity will be able to supercharge its growth before U.S. federal tax credits fall in 2016. On a price to sales basis the company is expensive with a ratio around 32, but it is still a small growth company.

SunPower is a big manufacturer, and it will be a major beneficiary of securitized bonds for distributed solar generation. It manufacturers high efficiency panels for space-constrained distributed systems, and these new finance techniques will provide a big boost. It already has experience with bond-backed solar developments, but traditionally these have only worked for utility plants like the €195 million it issued for an Italian solar farm.

Even though its revenue is not skyrocketing, SunPower is ready to grow with the distributed generation market. The company already has a big share of the U.S. distributed market with an estimated 22% of the residential market and 11% of the commercial market in Q1 2013. For value investors SunPower is a good stock to follow. Thanks to strong product offerings it is expected to post earnings per share (EPS) of $1.18 in 2014, and it trades at a more reasonable price to earnings ratio around 1.5. 

Be careful of investing in everything
Utility projects have been First Solar's specialty, and it has already seen bonds issued for its solar farms without government guarantees. Solar farms can be financed through the utilities with strong power purchase agreements, making their bonds more trustworthy in the eyes of investors. Back in 2012 MidAmerica successfully issued $850 million in bonds for First Solar's Topaz Solar Farm. 

First Solar's presence in the distributed generation market will be boosted once its panels are more efficient, but it will probably be late 2015 before its panels reach 16% efficiency. First Solar boasts a healthy profit margin of 12.2%, but technological limitations hurt its ability to take advantage of new financing techniques in the non-utility market.

Simply buying a broad-based solar fund is dangerous. To benefit from new asset-backed bonds a company's sales should be growing, not shrinking. The Chinese manufacturer LDK Solar has seen its revenue fall from $2.509 billion in 2010 to $0.863 billion in 2012. It is just steps away from bankruptcy with equity of $-0.896 billion in the most recent quarter.

Final thoughts
Bonds backed by payments from rooftop solar systems will be a huge boom for SunPower and SolarCity, allowing them to access a whole new market of investors. SolarCity is still a very speculative company with no profits in the immediate future, making SunPower a better option for risk-averse investors. First Solar is profitable, but it will be a while before it can boost its panel efficiencies enough to really take advantage of the distributed generation market. LDK Solar is so close to bankruptcy that it is best to ignore it.

Many new $0 down financing options are available that are being coupled with much lower priced, high performance systems, than those offered by SolarCity and Sunpower. Financing options such as all of the new PACE financing (HERO Program) that allows you to repay your financing through your property tax payments with the added benefit of tax deductible interest, FHAs $0 down solar financing, also with tax deductible interest and LightStream's new $0 down, non-collateralized solar financing, all of which allows you to keep the 30% federal tax credit and applicable cash rebates.

All of these financing options are available for Solar Home's new Hyper X solar modules that offer a higher PTC to STC ratio than over 100 of SunPower's solar module models and a better temperature coefficient for better performance in warm climates at nearly half the cost of SunPower's systems.

At less than $2.90 per watt, installed before incentives for standard performance systems and less than $3.40 per watt, installed, before incentives for ultra high performance, Hyper X solar systems, both SolarCity and Sunpower will have some stiff competition on their hands.

Solar City and Sun Power are doing some great things, and you're right that a boom is coming. But another business model to consider is the platform of solar comparison-shopping. The EnergySage marketplace allows consumers to solicit quotes from pre-screened installers and cross compare panels and financing options. This model lowers soft costs, saving the consumer time and money. Learn more -
