Some photovoltaic (PV) inverter manufacturers have designed and built transformer-less inverters to add to their existing line of transformer-type inverters for installation in the United States. Transformer-less inverters have been popular in Europe for quite some time.
Renewable power is all about innovation. One new breakthrough begets another, and the cycle persists as we continue to do more with less.
The growth of solar power is no exception, as the technology of photovoltaics (PV) benefits from innovations in cell materials and other component parts.
Solar-power researchers are always trying to squeeze more power out of their devices. After all, more power from solar cells effectively lowers the overall cost, and a more cost-effective cell will make solar photovoltaics more competitive with other forms of electrical generation.
As with many long-term investments, the upfront cost of implementation is one of solar power’s biggest challenges. Many companies offer assistance to energy consumers, but the latest is a joint effort to get photovoltaics (PVs) on homes.
Rooftop photovoltaic (PV) panels might not yet be a standard home appliance, but they could be on their way if current growth rates keep up. Even after several record years, installation figures continue to climb.
Broadway Electrical Co. Inc. recently completed the engineering, procurement and construction of the largest rooftop solar array in Boston. The project is located in the Boston/Dedham Commerce Park. Broadway Electrical will also provide the operations and maintenance for the installation.
Perhaps nothing showcases technology’s ability to innovate and change lives better than the science behind renewable power. Solar power’s high cost is well-established, but scientists at CalTech are developing cells with such hyper– efficiency they could potentially eclipse the question of price.
