When grid-tied solar panels make more energy than a customer needs, the excess is sent back to the electric grid along the same wires that carry power to the home when the sun is down.. Net metering is the utility billing practice of recording the excess energy generated by a solar installation and applying it to the customer''s bill as credit toward energy drawn from the grid.

Solar panels are devices that convert sunlight into electricity using photovoltaic cells. Learn about the components, types, and benefits of solar panels, and how they function in a solar power system.
Solar ovens work by capturing the sun''s energy and cooking foods without electricity or gas, and are popular with off-gridders and low-carbon seekers.
Climate change is a long-term change in the average weather patterns that have come to define Earth''s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term. Changes observed in Earth''s climate since the mid-20th century are driven by human activities, particularly fossil fuel burning, […]
Solar wind is composed of charged particles and the sun''s magnetic field and is continually released from our star. Explore the phenomenon in more detail here.
Solar Prominence: A prominence is a snakelike structure made of cooler, denser solar material that is suspended above the Sun''s surface by a strong local magnetic field. (When they are viewed against the solar disk, head-on rather than off the visible edge, they are called filaments.) Prominences can erupt when the magnetic structure becomes ...
Chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis. Chloroplasts are a type of plastid that are distinguished by their green color, the result of specialized chlorophyll pigments. In plants, chloroplasts occur in all green tissues.
Learn how solar panels convert sunlight into electricity using the photovoltaic effect and how they power your home. Find out the types, efficiency, and applications of solar panels and how to choose the best ones for your home.
How solar-thermal power can work at community scale. Here Comes the Sun Shower by Larry Hunter. The New York Times. February 9, 2009. Why the US government should be encouraging greater uptake of solar hot water systems. Estimating the Cost and Energy Efficiency of a Solar Water Heater: Energy.Gov Energy Saver. Do the sums add up for solar …
The solar wind is a flow of particles that comes off the sun at about one million miles per hour and travels throughout the entire solar system. First proposed in the 1950s by University of Chicago physicist Eugene Parker, the solar wind is visible in the halo around the sun during an eclipse and sometimes when the particles hit the Earth''s ...
The typical depth of mixed layers in the global deep ocean is <15 cm, which is mainly driven by natural biological and/or physical forces. By mapping sediment excess 210 Pb profiles throughout the ocean, we found the …
Solar energy is radiation from the Sun that can produce heat, cause chemical reactions, or generate electricity. Learn about the importance, potential, and applications of solar energy as a renewable and nonpolluting …
Solar Energy Definition . Our sun is a star made mostly of hydrogen and helium produces energy inside its core through a process called nuclear fusion, where hydrogen fuses together to make a ...
Solar energy is the most abundant energy resource on Earth. Each day, it''s harvested as electricity or heat, fueling homes, businesses, and utilities with clean, emission-free power. As the world pivots towards …
20 · This is, again, mainly driven by China, where renewables alone have not been able to satisfy the breakneck growth in electricity demand. After Asia, Europe is the second most …
3. What size solar inverters do I need for my system? The size of your solar inverter depends on your total power needs and solar array capacity. Generally, your inverter should be rated at 1.1 to 1.3 times your solar panel array''s wattage. For example, a 5kW solar panel system would typically require a 6kW inverter.
Solar is one of the fastest-growing energy sources in the world. The rapid development of solar power nationwide and globally has also led to parallel growth in several adjacent areas. Solar battery systems, electric vehicles, and heat pumps are all sectors likely to explode, amplifying the benefits of solar. Here are some quick facts about the ...
Solar panels cost between $8,500 and $30,500 or about $12,700 on average. The price you''ll pay depends on the number of solar panels and your location.
Dredging ensures cargo vessels of all sizes can dock and do not run aground. Increasing waterway depth: As sediment builds up on the bottom of the waterway, it reduces the depth of the water. Dredging strips away the accumulated debris, which can restore the water body to its original depth and reduce the risk of flooding.
The Earth''s ozone layer ozone layerThe region of the stratosphere containing the bulk of atmospheric ozone. The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth''s surface, in the stratosphere. Depletion of this layer by ozone depleting substances (ODS) will lead to higher UVB levels, which in turn will cause increased skin …
This article mainly explains the solar pump working, types, and applications. What is Solar Pump? A solar water pump is a type of pump that is driven by the electricity produced from solar panels. Solar pumps are manufactured to supply an eco-friendly and less expensive solution to pumping water in areas where there is no access to the power grid.
The Sun''s activity and brightness vary over time, but have little effect on Earth''s climate compared to human-caused greenhouse gases. Learn how solar cycles, grand minimums and global warming are related and what NASA is studying.
Solar collectors without concentration: they do not exceed ca. 80 °C, so they are used in the applications of low temperature thermal solar energy. They are characterized by not having concentration systems. Concentration solar collectors: they use concentration methods with optical elements (e.g. lenses or mirrors). These devices of more ...
