Solar power generation in the dog days
The "Dog Days" of summer, from late July to late August, are traditionally linked with heat and heavy air. While the term describes sultry weather, power grids also face their own Dog Days. They were historically the period following the heliacal rising of the star system Sirius (known colloquially as the "Dog Star"), which Hellenistic astrology connected with heat, drought, sudden thunderstorms, lethargy, fever. . Dog Days, the phrase invokes the hottest, most stifling days of summer. Once blamed for stirring fever and unrest, this seasonal. . The solar industry has done a spectacular job lowering costs in the past three years, slashing per-watt costs in half. But that price freefall, driven by the massive scale-up of Chinese manufacturers, has put dozens, if not hundreds, of solar companies on the endangered list. Of the many recent solar startups, the MIT spin-off has been notable for playing its cards right. [PDF Version]FAQs about Solar power generation in the dog days
What are Dog Days astrology?
The dog days or dog days of summer are the hot, sultry days of summer. They were historically the period following the heliacal rising of the star system Sirius (known colloquially as the "Dog Star"), which Hellenistic astrology connected with heat, drought, sudden thunderstorms, lethargy, fever, mad dogs, and bad luck.
Why does the Dog Star Rise before the Sun?
Around late July, the Dog Star rises in the eastern sky just before the sun. Ancient observers believed this alignment with the sun contributed to the extreme summer heat, thinking it intensified the season's already sweltering conditions.
When did the Dog Days start?
In antiquity, the dog days were usually reckoned from the appearance of Sirius around 19 July (Julian) to relieving rains and cool winds, although Hesiod seems to have counted the worst of summer as the days leading up to Sirius's reappearance.
Are the Dog Days still a thing?
The concept behind the dog days hasn't disappeared. While most of us aren't tracking Sirius at dawn, the phrase still captures the unmistakable feeling of late summer, when the air is heavy, energy dips and people instinctively seek out shade or air conditioning.
New thermochemical energy storage system in the United States

Price of a 20-foot collapsible shipping container in the United States
As of July 2025, the 20 ft shipping container price to buy ranges from about $2,100 for a used container to $3,700+ for a new (one-trip) container. Both sizes are large enough to hold a substantial amount of freight and fit into loading slots on container ships. Generally, used 20′ containers start around $1,500, with newer “one-trip” models ranging from $2,500 to. . The 20 ft shipping container is a good choice for smaller space requirements. These can be delivered with smaller rollback tow trucks so they can fit in spaces where larger containers may not work. [PDF Version]

Microgrid Hierarchical Modeling
This paper gives an outline of a microgrid, its general architecture and also gives an overview of the three-level hierarchical control system of a microgrid. In the event of disturbances, the microgrid disconnects from the. . High penetration of Renewable Energy Resources (RESs) introduces numerous challenges into the Microgrids (MG), such as supply–demand imbalance, non-linear loads, voltage instability, etc. 15 minutes, with the goal of minimizing microgrid's operating costs. The second level takes part in frequency control. . The Microgrid (MG) concept is an integral part of the DG system and has been proven to possess the promising potential of providing clean, reliable and efficient power by effectively integrating renewable energy sources as well as other distributed energy sources. However, challenges, such as computational intensity, the need for stability analysis, and experimental validation, remain to be addressed. [PDF Version]
Solar energy does not generate electricity on rainy days
Because solar panels rely on light, not heat, they can still generate power on cloudy or rainy days at a reduced capacity. On average, they produce 10% to 25% of their normal energy output under overcast conditions. It's important to note, however, that in areas with. . Solar panels continue to generate electricity even when the sky is overcast and rain is falling, though performance is noticeably diminished compared to a bright, sunny day. [PDF Version]

Days of green wind power generation
Energy output is a function of power (installed capacity) multiplied by the time of generation. This interactive chart shows installed wind capacity – including both onshore and offshore – across. . In this interactive chart, we see the share of primary energy consumption that came from renewable technologies – the combination of hydropower, solar, wind, geothermal, wave, tidal, and modern biofuels. It involves using wind turbines to convert the turning motion of blades, pushed by moving air (kinetic energy) into electrical energy (electricity). Once built, these turbines create no climate-warming greenhouse gas emissions, making this a “carbon-free” energy source that can provide electricity. . Generation capacity has grown rapidly in recent years, driven by policy support and sharp cost reductions for solar photovoltaics and wind power in particular. [PDF Version]
The United States does not need photovoltaic panels
In reality, the US needs solar panels on about 700,000 acres of land in order to meet the administration's goal of transitioning the nation to 100% renewable energy by 2035.
