Smallcap Stocks on Solar Technologys Cutting Edge
Posted by: James Brumley / Category: InvestmentSolar energy does work, and it can be profitable. Thats no longer in question. The next focal point for the industry is going to be making solar power more cost effective, and/or more efficient. A handful of small, publicly-traded companies are working on technological advancements that will not only bring solar energys cost closer to gas or coal energy prices, but also make it feasible to integrate the technology into our current infrastructure.
Here are some of solar powers most compelling current developments, and a few companies ” some of them smallcaps - that could make their investors glad to be owners.
Taking the Panel Out of Solar Panel
Traditional photovoltaic solar cells are big, fragile, and theyre heavy enough to make them difficult to mount just anywhere. And, they can only be attached or mounted to a large flat surface. That limits their use. To get around this challenge, solar panel paint is being developed. Like any paint, this specialized paint can be installed anywhere, regardless of the underlying shape of the structure being painted.
Though no publicly-traded stock can be purchased as a way of investing in this paint, dont assume thats a permanent problem. When corporations see that the technology is viable, theyll likely adopt and begin marketing it.
Thin Film Solar Cells
Formerly, solar cell panels were heavy and fragile, and therefore difficult to install ” one of their limiting factors. Recent advancements have flattened solar panels to paper-thin widths, without sacrificing efficiency. Best of all, these thin film panels arent rigid like previous ones. That flexibility makes thin-film panels considerably easier to mount without the risk of breaking.
First Solar Inc. (NASDAQ: FSLR) is one of the companies leading the thin-film effort. The companys cadmium telluride panels cost less than $1.00 per watt to make, which is approaching comparability with photovoltaic cells.
Bigger may not necessarily be better though. Smallcap company XsunX, Inc. (OTCBB: XSNX) believes that its ASI-120 (amorphous silicon) solar module can provide an even lower cost per watt while supplying electricity in a wider variety of geographical environments. The companys thin-film modules find a balance between the common silicon wafer modules, which are more costly, and lower rated power thin film modules, which are fairly ineffective.
Another entry into the thin-film arena is Uni-Solar Ovonics triple junction thin film solar cell, which is quickly proving to be very cost effective. The company is wholly-owned by smallcap company Energy Conversion Devices (NASDAQ: ENER), for interested investors.
Making It Is One Thing; Storing It Is Another
As solar energy production has moved past the trial stage and into the application stage, a problem has surfaced ” the sun doesnt shine 24 hours a day. To become fully powered by the sun, the energy collected when the sun is shining needs to be stored for use when the sun isnt shining. This is where batteries come in.
Theres an inherent problem with current battery technology though. Most of the batteries capable of handling that kind of power storage are made of solid components, which decompose to the point of uselessness pretty quickly. That may be a mot problem. However, considering these same batteries are also slow to charge, and have a limited lifespan. The answer to the problem is promising liquid-based batteries.
The problem so far? MIT is developing the liquid battery, which doesnt leave an investor any options to tap into its success. Once proven though, it is expected that smallcap companies will be the first to warm up to the technology.
In the meantime, solid battery-maker Valence Technology Inc. (NASDAQ:VLNC) has a product for every imaginable need automotive, industrial, and yes, even storage solutions for power generated by wind and solar sources. Smallcap stocks like EnerSys (NYSE: ENS) and Advanced Battery Technologies Inc. (NASDAQ: ABAT) may be good bets within the utility battery group as well.
That said, there are at least a couple of dozen battery companies that could actually meet the needs created by the continued growth of solar power. Some are better than others, but thats not a function of size.
Bio-Based Backsheets Cheaper Than Petroleum
Ironically, though solar power was mostly developed to get around the use of petroleum to supply energy, petroleum is actually used as one of the materials in a solar panel. Where? Not the panel itself; those are still made of silicon or similar materials. However, the protective covering for solar panels ” called a backsheet ” uses petroleum in its construction.
The problem? Backsheets are expensive enough as is, but the cost of the back sheet can skyrocket if crude oil prices move upward. The alternative to expensive petroleum-based backsheets is bio-based backsheets. In bio-backsheets, plant materials are used instead of petroleum, which can significantly lower the cost of the entire panel module. Smallcap company BioSolar Inc. (OTCBB: BSRC) is the leader of the bio-backsheet advance.
BioSolar had been primarily focused on backsheet technology for the most common crystalline silicon (C-Si) photovoltaic solar cells the markets biggest seller as of right now. However, copper-indium-gallium-selenide (CIGS) and cadmium telluride (CdTe) thin-film panels are quickly becoming competitors of C-Si panels because of their similarly-low costs and impressive power production. So, BioSolar has recently begun work on bio-backsheets for CIGS and CdTe thin panels as well.
Just a Window? What a Waste.
Many homes as well as most commercial buildings cover a great deal of their surface are for glass. This is partially a matter of convenience and expense, but also serves an aesthetic purpose. More important to the industry though, its a waste of a lot of solar power real estate. What if a window could also serve as a solar panel though, yet still be transparent?
Turning glass into an effective solar panel without sacrificing transparency isnt science fiction for New Energy Technologies, Inc. (OTCBB: NENE). This small company has devised a way to coat windows with silicon nanoparticles that actually convert ultraviolet light into electricity. Needless to say, if an entire building could become a self-contained electricity supply, the implications would be enormous.
Investors, Listen Up
Given the ever-changing nature of solar power technology, it would be wise to stay abreast of the technology trends described above as much as it would be to continually monitor just the companies. Certainly the stocks mentioned here are among the current leaders in their respective categories, but these organizations really are only as good as their technology. And, that only matters if their products are profitable as well as competitive.
We feel smallcap stocks in particular can quickly surface ” often without warning - as worthy investments since their respective companies are nimble. Either way though, the industrys projected growth is undeniable, so one company or another is going to benefit from the dollars being poured into the efforts described above.
