    Solar energy is all around us. Learn how solar panels harness the power of the sun to produce electricity.

    Solar energy: what you need to know

    Solar power is simply usable energy generated from the sun in the form of either electric or thermal energy. Solar energy is captured in a variety of ways, with the most common being a solar photovoltaic system, or PV system, that converts the sun’s rays into usable electricity. Aside from using photovoltaics to generate electricity, solar thermal energy, or concentrating solar power (CSP), is commonly used to heat indoor spaces or fluids. Residential and commercial property owners can install solar hot water systems and design their buildings with passive solar heating in mind to fully take advantage of the sun’s energy with solar technology.

    Types of solar energy systems

    Interested in benefiting from solar power? Solar panels are installed at three main scales: residential, commercial, and utility. Homeowners can take advantage of residential-scale solar, typically in the form of rooftop solar or in ground-mounted solar installed in open land. Generally, residential solar systems are between 5 and 20 kilowatts (kW), depending on the size of the home.

    Commercial solar energy projects are typically installed at a greater scale than residential solar. While individual installations can vary greatly in size and cost, commercial-scale solar arrays serve a consistent purpose: to provide on-site solar power to businesses and nonprofits. Finally, utility-scale solar projects are typically large-scale solar power plants that are several megawatts (MW) in size — utility-scale solar installations provide solar energy to a large number of utility customers.

    For some solar shoppers who may not be able to install solar on their property due to cost or other factors, community solar is a viable solar option that more directly connects utility-scale solar energy projects to residential consumers. As such, community solar farms are typically built in central locations as opposed to on any single property. Subscribers (homeowners, renters, businesses, or non-profits) can join a community solar project to receive many of the benefits of solar power without installing solar panels on their property.

    How do solar panels work?

    A solar panel (also known as a solar module) consists of a layer of silicon cells, a metal frame, a glass casing unit, and wiring to transfer electric current from the silicon. Silicon (atomic #14 on the periodic table) is a nonmetal with conductive properties that allow it to absorb and convert sunlight into usable electricity. When light hits a silicon cell, the light causes electrons in the silicon to be set in motion, initiating a flow of electric current. This is known as the “photovoltaic effect,” and it describes the general functionality of solar panel technology.

    The science of generating electricity with solar panels boils down to this photovoltaic effect. It was first discovered in 1839 by Edmond Becquerel and can be thought of as a property of specific materials (known as semiconductors) that allows them to create an electric current when they are exposed to sunlight.

    The photovoltaic process works through the following broad steps:

    • The silicon photovoltaic solar cell absorbs solar radiation
    • When the sun’s rays interact with the silicon cell, electrons begin to move, creating a flow of electric current
    • Wires capture and feed this direct current (DC) electricity to a solar inverter to be converted to alternating current (AC) electricity

    A brief history of solar power

    In 1954, Bell Labs developed the first silicon photovoltaic cell. Although solar energy had previously been captured and converted into usable energy through various methods, only after 1954 did solar power begin to become a viable source of electricity to power devices over extended periods of time. The first solar cells converted solar radiation to electricity at an efficiency of 4 percent — for reference, many widely available solar panels today can convert sunlight to solar power at above 20 percent efficiency, a number constantly on the rise. Although solar energy adoption was slow at first, a number of state and federal incentives and policies contributed to driving down the cost of solar far enough to become more widely adopted.

    The cost of solar energy

    Concurrent with an increase in solar efficiency, the cost of solar panels has fallen substantially. In the last decade alone, the cost of a solar panel installation fell over 70 percent, and many industry experts predict that will continue to fall in the years to come.

    Additionally, depending upon where you live, several rebates or incentives for solar power may contribute towards lowering the cost of solar energy even further. Nationwide, the federal Investment Tax Credit (ITC) is one of the primary incentives available to anyone interested in solar energy, as it allows you to deduct 30 percent of the cost of installing a solar array system from your federal taxes. This incentive won’t last forever: in 2033, the federal ITC steps down to 26% and it will go away completely for residential solar installations in 2035. Many states and utilities offer further incentives (such as net metering) in addition to the federal ITC, dropping the cost of solar power even further.

    Solar energy is a renewable power source

    Solar energy is a clean, inexpensive, renewable power source that is harnessable nearly everywhere in the world — any point where sunlight hits the surface of the earth is a potential location to generate solar power. And since solar energy comes from the sun, it represents a limitless source of power. Renewable energy technologies generate electricity from resources that are infinite.

    Compare producing electricity with renewable resources to fossil fuels: it took hundreds of thousands of years for oil, gas and coal to form. So, every time one of those resources is burned to create electricity (and emissions!), that finite resource is moved marginally closer to depletion. Using a renewable resource — such as wind, solar and hydropower — to generate electricity does not deplete that resource. There will always be consistent sunlight shining on Earth’s surface, and after turning sunlight into electricity, there is still an infinite amount of sunlight to turn into electricity in the future. That is what makes solar power, by nature, renewable energy.

    While the current electricity mix in the United States is still made up largely of fossil fuels like oil and gas, renewable energy sources like solar are steadily becoming a larger part of the country’s energy profile as the cost becomes more competitive.

    Should you go solar?

    When it comes to installing solar panels and switching to a more eco-friendly energy source, there’s not a one-size-fits-all approach. There are several questions you should ask to help determine if your home or business is a good candidate for solar:

    • How much electricity do you consume and how much does electricity cost in your area? The more electricity you use, and the more you pay for it, the more you’ll save by going solar.
    • Do you own your home? If you live in a multi-family home or rent the property, it will be much more difficult to install solar than if you own a single-family home.
    • Is your roof good for solar? The ideal roof for solar would be one that’s pretty spacious, is in good condition, isn’t too complex, is southern-facing, and receives plenty of direct sunlight. If not, you should consider if you have land space for a ground-mounted system.
    • Are there local, reputable solar companies in your area that can perform the installation? If you don’t live in an area with multiple installers competing for your business, you may end up paying a premium.
    • What incentives are available where you live? Local and state incentives could end up saving you thousands of dollars on your solar energy system, significantly shortening your payback period.

    If some of these characteristics aren’t aligned with your situation but you’re still interested in going solar, read our article about if solar is right for you for more information on whether you’re a good fit.

    What to know about the solar industry

    According to the Solar Energy Industries Association (SEIA), solar capacity has grown about 33 percent, on average, over the past decade. In fact, the Department of Energy (DOE) reports that the United States has about 97.2 gigawatts (GW) of installed solar power capacity to date — enough to provide clean energy to about 18 million homes.

    As solar capacity continues to grow, so too does the need for new solar jobs. From installing to manufacturing to performing operations and maintenance to educating consumers, there are a number of things you could be doing as a solar industry employee! As of December 2021, the solar industry supported 255,037 jobs based on data from the Interstate Renewable Energy Council (IREC)’s National Solar Jobs Census — a 9.2% increase from 2020.

    The Rapid proliferation of solar power nationwide and globally has also led to parallel growth in several adjacent areas. Notably, solar battery systems, electric vehicles, and heat pumps are all sectors poised to explode alongside the solar industry by augmenting the benefits of solar.

    Want to support the solar industry? Consider switching your electricity generation source to solar power! Whether you install solar panels on your home or business, or subscribe to a community solar farm, you’ll be adding to the total capacity of installed solar energy, while helping grow the clean energy economy.

    In a Flash

    The Sun provides a renewable source of light and heat energy.

    Solar Energy

    Solar energy is energy provided by the Sun in the form of solar radiation. Every day the Sun radiates, or sends out, an enormous amount of energy. This Radiant energy has powered life on earth for millions of years and is one of the most important source of energy for life forms. Solar energy is a renewable resource and it is becoming increasingly common that this energy is converted and used as an alternative to fossil fuels. Many technologies can harvest it directly to produce solar electricity for use in homes and businesses globally.

    What is solar energy?

    Solar energy is radiant light and heat from the Sun, and can be harnessed using a range of technologies such as solar heating, solar photovoltaic and solar thermal electricity. Solar energy is a renewable source of energy that is sustainable and totally inexhaustible, unlike fossil fuels that are finite.

    Solar energy is used for heating water for domestic use, heating space in buildings and generating electrical energy.

    It is considered an environmentally friendly source of energy because it comes directly from the Sun; it does not involve the burning of fossil fuels.

    Solar radiant energy

    Solar Radiant or light energy is produced in the Sun as a result of nuclear fusion reactions and is transmitted to the earth through space by electromagnetic radiation in quanta or packets of energy called photons. This light energy can be utilised by a process called photovoltaic, which produces electricity directly (Photo meaning light and voltaic relating to electricity). This process is being used more and more as the technology is developed and becomes more economic. It is used widely in solar powered calculators and other devices.

    solar, energy, clean, power

    Solar thermal energy

    Solar Thermal or heat energy is used widely in Australia for heating water for our domestic use in Solar Water heaters. This is an excellent and economic energy solution as, by using the Sun’s heat for making our hot water, we cut down on the amount of fossil fuels needed tobe burnt to supply electricity to do the same thing. The technology is now developing which will use solar thermal energy to produce steam at high enough temperatures and pressures to drive steam turbines for electricity generations.

    Harnessing Solar Energy

    The strength of the solar energy available at any point on the earth depends, on the day of the year, the time of day, and the latitude of the collection point. The amount of energy collected can be further changed depending on the orientation and shape of the object doing the collection. Insolation is a measurement of the amount of solar energy that reaches the surface of the Earth.

    The amount of insolation an area receives depends upon the Sun’s angle, the amount of dust and water vapor in the air, and the amount of Cloud cover. Less than half of the radiation energy we receive from the Sun makes it to the ground. The rest is absorbed by the atmosphere or reflected-back out into space.

    solar, energy, clean, power

    The strength of solar radiation at the outer edge of the earth’s atmosphere when the earth is taken to beat its average distance from the Sun is called the solar constant, the mean value of which is 1.37 106 ergs per sec per cm2, or about 2 calories per min per cm2.

    Active Solar Energy

    Active solar technologies use electrical or mechanical devices to actively convert solar energy into another form of energy, most often heat or electricity.

    Active solar heating systems use a collector and a fluid that absorbs solar radiation. Fans or pumps circulate air or heat-absorbing liquids through collectors and then transfer the heated fluid directly to a room or to a heat storage system. Active water heating systems usually have a tank for storing solar heated water.

    Passive Solar Energy

    Passive solar technologies do not use any external devices. Instead, they take advantage of the local climate to heat structures during the winter, and reflect heat during the summer.

    Passive solar space heating happens when the Sun shines through the Windows of a building and warms the interior. Building designs that optimise passive solar heating usually have south-facing Windows that allow the Sun to shine on solar heat-absorbing walls or floors during the winter. The solar energy heats the building by natural radiation and convection. Window overhangs or shades block the Sun from entering the Windows during the summer to keep the building cool.

    The Sun

    The Sun is the star that dominates our solar system. The amount of energy emitted by the Sun as radiation is quite constant. This energy output is generated deep within the Sun. As a star, the Sun is made up of 71% hydrogen, 27% helium, and 2% other elements. At the center of the Sun the density is 150 times that of water and the temperature is almost 16,000,000 Kelvin, which causes the nuclei of individual hydrogen atoms to undergo nuclear fusion (in other words they join-together). The result of this is that two hydrogen nuclei combine to make one helium nucleus, and energy is released in the form of radiation. Vast numbers of fusions occur every second, generating energy beyond our imagination. The energy produced moves out towards the solar surface by radiation and then by convection through the turbulent mixing of gases on the Sun’s surface.

    The Sun has produced energy for many millions of years and will do so for many millions more. It is estimated that there is enough hydrogen still in the Sun’s core to last another 4.5 billion years.

    Solar energy, as we refer to it, is the solar radiation (light and heat) that reaches the earth. Every day the Sun radiates enormous amounts of heat and light energy. The planet and the atmosphere absorb some of this energy with the remainder being reflected-back out into space.

    The heat energy we receive from the Sun through radiation is the energy that gives life to living things. It is also the immense source of energy that generates the planet’s weather, creating wind and the planet’s water cycle.

    Solar energy is radiant light and heat from the Sun.

    Solar Photovoltaic (PV)

    Some materials are sensitive to the Sun’s radiant or light energy and react in such a way that we can harness this reaction to produce electricity.

    The Sun’s light energy can be converted directly into electricity in a single process using Photovoltaic (PV) cells, otherwise known as solar cells. A PV cell is a thin plate of light sensitive material made primarily of silicon, the second most abundant element in the earth ‘s crust, and the same semiconductor material used for computers.

    When the silicon is combined with one or more other materials, it exhibits unique electrical properties in the presence of sunlight. Electrons are agitated by the light and move through the silicon. This is known as the photovoltaic effect and results in direct current (DC) electricity.

    Many PV cells are linked together to create a standard PV module, which in turn are linked together into a PV array. PV modules have no moving parts, are virtually maintenance-free although they should be kept clean and clear of shading, and have a working life of 20-30 years.

    The PV array produces direct current (DC) electricity. An inverter is used to convert the DC to alternating current (AC), so the power is the same as normal grid power and can be used in household appliances. The inverter is a box of electronics, like a computer.

    The Photovoltaic (PV) cell was discovered in the early 1950’s by researchers examining the sensitivity of a silicon wafer to sunlight. By the late 1950s, PV’s were used to power U.S. space satellites and this success generated commercial applications for PV technology. The simplest PV systems power small calculators and wrist watches used every day, while more complicated systems provide electricity to pump water, power communications equipment, and even provide electricity to our homes.

    Large banks of solar cells maximise the amount of solar energy they can generate.

    Solar Electric Power

    In this approach, electricity is converted directly from solar energy through solar cells known as photovoltaic cells – photo for light and voltaic for energy.

    Normally mounted on the roof or in a location with maximum sun exposure, the photovoltaic (PV) array components convert energy from the sun into electric current to power appliances and other household devices.

    A PV system requires little maintenance and can produce power for more than 20 years.

    Solar Thermal Energy

    Heating water using electricity can make up 14-25% of the average home’s utility bill. A residential solar water heating system can be designed to meet between 50 and 80% of a home’s water heating requirements.

    A solar water heating system requires collectors to absorb the sun’s energy and a storage system to hold the energy until it is needed. The systems used to store thermal energy are similar to conventional water heaters. The heated water is circulated through the home or building using pumps.

    Georgia’s Solar Potential

    The potential for solar energy use in Georgia is dependent upon the amount of sun shining on the earth’s surface called solar insolation. Several factors such as weather patterns, humidity and haze can affect local insolation levels.

    As can be seen on this solar map, insolation values in Georgia are significant enough to support solar energy systems in our state, with the southern two-thirds of Georgia having solar insolation values equivalent to most of the state of Florida.
