The Incompatability of Solar Systems and the Standard Grid


Many question the ability of renewable energy sources, such as wind- or photovoltaic-systems, to effectively and sufficiently supply households with electricity. In its encounters with international solar markets, Solar Bankers has frequently observed considerable performance-variations in wind- and photovoltaic-technologies. Such variations render current renewable-energy technologies very unreliable and inconsistent supplies of electricity. PV power plants, or similar innovations, are thus incompatible with the standard grid, which constantly demands maximum capacity, and thus may not be directly integrated therewith.

Aerosol coalescence may result in performance-variations of up to 80% in PV-systems. And these variations may emerge – unpredicted – within minutes, or even seconds. This results in a volatility of PV-productivity that endows current solar-technology with its so-often-discussed infamy. When encountering negative performance-variation, for instance, utility companies feed energy (often from non-renewable sources) into the grid, in order to maintain stability of electricity supply. And, naturally, society’s consistent and incessant demand for maximum-capacity electricity supply forces utility companies to implement such measures of stabilizing energy outputs.

Due to the rapid emergence of natural productivity-decreases in solar systems, utility companies keep reserve electricity-generation infrastructures to prepare for quick reaction. These reserve-generators, however, are kept constantly active, mainly for suppliers to cope with unanticipated fluctuations in productivity coinciding with unfluctuating demand for the supply of electricity. This continuous non-dormancy results in superfluous, unproductive energy being consistently expectorated when the outputs of solar installations are stable. In addition to this, one must note, the energy here superfluously produced is most commonly derived from hydrocarbon fuel, or other, non-green resources.

This, however, implies that current integration of vast, public photovoltaic installations with the general grid constitutes, really, an ineffective strategy of saving hydrocarbon-based energy. If utility companies compensate for the volatility of renewable energy sources with the exploitation of hydrocarbon fuels, one might as well remove renewable electricity all together. Consider, the two primary, and obvious, benefits of integrating renewable energy with the standard grid – environmental preservation and the conservation of hydrocarbon resources – are nullified by utility companies’ current schemes. This is because, in the end, the contributions of renewable energy sources to the standard grid’s electricity supply – what essentially enables the benefits of such systems to materialize – are insignificant in comparison to the contributions still derived from non-renewable, hydrocarbon resources.

It appears one must seriously ask oneself: what is the point of utility companies feeding the public grid with renewable energy, if the benefits of green technology are not actually derived therefrom?

One must acknowledge though, that US utility companies are not directly responsible for these inefficiencies. They are definitely not responsible for photovoltaic systems’ unreliable technological nature. One may, however, criticize the inconsistent reasoning of these companies, if they, for whatever reason, choose to acquire and utilize assets whose productivity THEY KNOW to be so volatile.
