«Our main conclusion is that geophysically - forced variability in wind and solar generation means that the amount of electricity demand satisfied using wind and solar resources is fairly linear up to about 80 % of annually averaged electricity demand, but that beyond this level of penetration the amount of added wind and solar generation capacity or the amount of electricity storage needed would rise sharply.»
For this reason, even if solar generation becomes profitable without subsidies at low levels of penetration, there is a system - dependent threshold of installed PV capacity beyond which adding further solar generators would no longer be profitable.
In a recent study, IER found that at low penetration levels, solar production could reduce stress on the electrical grid.
«A peer - reviewed paper [Krivova et al.] published in the Journal of Geophysical Research finds that reconstructions of total solar irradiance (TSI) show a significant increase since the Maunder minimum in the 1600's during the Little Ice Age and shows further increases over the 19th and 20th centuries... Use of the Stefan - Boltzmann equation indicates that a 1.25 W / m2 increase in solar activity could account for an approximate.44 C global temperature increase... A significant new finding is that portions of the more energetic ultraviolet region of the solar spectrum increased by almost 50 % over the 400 years since the Maunder minimum... This is highly significant because the UV portion of the solar spectrum is the most important for heating of the oceans due to the greatest penetration beyond the surface and highest energy levels.

Lee told Utility Dive the law is needed due to unique pressures on HECO, which faces a 100 % renewable energy mandate to meet by 2045 and the highest level of per - capita rooftop solar penetration of any U.S. state.
The WV reduction at high levels would increase solar near infrared penetration into the mid-lower atmosphere, and the WV increase at lower - mid levels would increase the lower atmospheric greenhouse effect.
«The two degree scenario proposed by the authors would require wind and solar increasing to 9 % of China's total power generation, which is a sizable increase from today's levels, but not out of line with penetration levels that have been achieved in other countries,» she told RTCC.
There may be some level of wind and solar penetration where the cost of integrating them into the grid exceeds the benefit, but we are nowhere close to that level yet.
