Solar leasing promoters have long claimed that electricity costs will keep rising, but we haven’t see this happening – yet. Actually, almost all of the standard generation sources are benefiting from lower costs – natural gas is low, coal is low, and nuclear is… well it’s not dramatically more expensive than it has been. There is no doubt in my mind, however, that prices are going to go up.
Companies using OSIsoft’s PI system gathered this week in London at the OSIsoft EMEA Users Conference to talk about the realities of what Martin Otterson calls the velocity, variety and volume of data in the modern business world.
Solar inverters are becoming more intelligent this year. California’s Rule 21, which is now partially in effect, governs the safety of PV arrays and their interconnection communications with the local investor-owned utility.
The rule has three basic phases, of which the first came into effect Sept. 8 under a draft resolution of the California Public Utilities Commission (CPUC). The effective date for the other two phases has not yet been set, however a CPUC vote on the draft resolution is set for October 12, and a California Smart Inverter Working Group (SWIG) workshop on Phases 2 and 3 is scheduled for Nov. 17.
Environmental Protection Agency Administrator Scott Pruitt On Oct. 8 in Kentucky announced the Trump Administration’s plan to repeal the Clean Power Plan, and stated that the solar, wind and other renewable energy tax credits should be eliminated so the industry can compete on its own against coal and other energy sources.
The Swiss Team took first place in engineering with a perfect score of 100 possible points. For the Engineering Contest, each competing house was evaluated by a group of prominent engineers who determined which house best exemplifies excellence in innovation, system functionality, energy efficiency, system reliability, and documentation through their project manual and construction drawings.
Bob Dixon, presenting the award said, “The jury believes the first-place house in the Engineering Contest offers comprehensive performance modeling that sports clear graphs, detailed explanations and a variety of representations. The quality of the thermal envelope is exceptional and carefully calibrated to the target climate with very good resistance to heat flow, a solid focus on airtightness, and high-quality components such as triple-glazed windows and sliding doors.”
Tesla Inc. has fired an undetermined number of employees following a series of performance evaluations after the company significantly boosted its workforce with the purchase of solar panel maker SolarCity Corp.
The National Renewable Energy Laboratory’s solar cell efficiencies chart depicts confirmed conversion efficiencies for research cells from 1976 to date, for several PV technologies. But as conventional crystalline silicon (c-Si) PV modules approach peak efficiency, with the leap from lab to life—or from demonstration to mass production—occasionally taking over 30 years, the final question is: what is the additional watt class worth?
Power-to-gas (P2G)—the conversion of electrical power into gaseous energy carriers—is a quickly improving and potentially disruptive energy conversion technology.
It is not always good to be first. Last June, San Diego Gas & Electric (SDG&E) was the first utility in California to hit its net-metering cap and move to Net Energy Metering 2.0 (NEM 2.0). Now, SDG&E will again be the first utility to start the shift to time-of-use (TOU) period, effective on Dec. 1, 2017.
As the Atlantic continues to churn out some of the deadliest storms on record, the repercussions continue to rock the South and southeastern U.S. Whether it is the physical impact of the recent storms on solar projects or the economic impact throughout energy markets, how do these events affect the solar industry, and to what extent?
