Another major complicating factor to the solar electric industry is that capital market(s) are always in search of financial bubbles to exploit; where the goal of investment is to privatize the profits and social the costs. Throwing large amounts of investment money at this “new technology” has led to the commoditization of solar technology, this has produced many systems installed by larger, “big box store type” national solar franchises whose business model of providing solar equipment “leases” has been questioned by many, as they typically are more expensive than a system purchased outright. These leases almost make the re-selling of a home with a solar lease very difficult.
Almost without exception, all the market forces are moving in the direction of product innovation and using less raw materials – and lower costs. This process continues at an un-abated pace, as this is a new developing industry that is certainly not mature. Unlike developed industries, the photovoltaic industry has virtually no entrenched powerful controlling interests – to retard the rate of change or control its direction or rate of adoption. Utilities are under the direction of public regulation authorities and because of laws like PURPA, Utilities cannot stop widespread PV adoption – now that these systems are widely affordable and 43 states have adopted net metering, though Hawaii has reached a limit previously set.
Today, the most rapidly growing segment of this photovoltaic electricity production is the utility mega-watt scale solar farms, using N-S horizontal trackers and large fixed angle ground mounts – (this utility market has recently seen the most growth in sheer numbers of PV watts installed).
What will this industry look like 3 or 5 years from now?
Coupling these systems with reserve batteries banks on the large or residential level has offered promises of future advancements, but currently the battery bank option is not providing economic quantifiable advantages. Many years may pass before the price of battery banks drop far enough, to be more than an expensive added feature and provide a real economic advantage to and end user.
