Different Types of SolarEnergy Systems plus WindEnergy Systems

Many power plants today use fossil fuels as a heat source to boil water. The steam from the boiling water spins a large turbine, which drives a generator to produce electricity. However, a new generation of power plants with concentrating solar power systems uses the sun as a heat source. The three main types of concentrating solar power systems are: linear concentrator, dish/engine, and power tower systems.

Linear concentrator systems collect the sun's energy using long rectangular, curved (U-shaped) mirrors. The mirrors are tilted toward the sun, focusing sunlight on tubes (or receivers) that run the length of the mirrors. The reflected sunlight heats a fluid flowing through the tubes. The hot fluid then is used to boil water in a conventional steam-turbine generator to produce electricity. There are two major types of linear concentrator systems: parabolic trough systems, where receiver tubes are positioned along the focal line of each parabolic mirror; and linear Fresnel reflector systems, where one receiver tube is positioned above several mirrors to allow the mirrors greater mobility in tracking the sun.

A dish/engine system uses a mirrored dish similar to a very large satellite dish. The dish-shaped surface directs and concentrates sunlight onto a thermal receiver, which absorbs and collects the heat and transfers it to the engine generator. The most common type of heat engine used today in dish/engine systems is the Stirling engine. This system uses the fluid heated by the receiver to move pistons and create mechanical power. The mechanical power is then used to run a generator or alternator to produce electricity.

A power tower system uses a large field of flat, sun-tracking mirrors known as heliostats to focus and concentrate sunlight onto a receiver on the top of a tower. A heat-transfer fluid heated in the receiver is used to generate steam, which, in turn, is used in a conventional turbine generator to produce electricity. Some power towers use water/steam as the heat-transfer fluid. Other advanced designs are experimenting with molten nitrate salt because of its superior heat-transfer and energy-storage capabilities. The energy-storage capability, or thermal storage, allows the system to continue to dispatch electricity during cloudy weather or at night.

We have been harnessing the windenergy for hundreds of years. From old Holland to farms in the United States, windmills have been used for pumping water or grinding grain. Today, the windmill's modern equivalent—a "wind turbine design" - can use the windenergy to generate electricity.

How It Works

Windpower turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the windenergy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is actually much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller, and the turning shaft spins a generator to make electricity.

Applications

These wind turbines near Lamar, Colorado, are part of the 162-MW Colorado Green Wind Farm. Each turbine produces 1.5 megawatts of electricity.

A Windpower turbine can be used as stand-alone applications, or they can be connected to a utility power grid or even combined with a photovoltaic (solar cell) system. For utility-scale (megawatt-sized) sources of wind energy, a large number of wind turbines are usually built close together to form a wind plant. Several electricity providers today use wind plants to supply power to their customers.

Stand-alone windpower turbines are typically used for water pumping or communications. However, homeowners, farmers, and ranchers in windy areas can also use wind turbines as a way to cut their energy billing.

Small windpower systems also have potential as distributed energy resources. Distributed energy resources refer to a variety of small, modular power-generating technologies that can be combined to improve the operation of the electricity delivery system.

Evaluating Your Site's Solar Resource for Solarpower Electricity

The solar resource across the U.S. is ample for solar electric systems—also known as "photovoltaic cell" (PV) systems—because they can use both direct and scattered sunlight. However, the amount of solarpower electricity generated at a particular site depends on how much of the sun's energy reaches it. Thus, PV "photovoltaic cell" systems function most efficiently in the southwestern United States, which receives the greatest amount of solarenergy.

Before you buy a PV "photovoltaic cell" system, you'll want to be sure your site has enough solarenergy to meet your electricity needs efficiently and economically. 

When evaluating your site, you'll also need to consider both the geographic orientation and the tilt of your solar panels—PV "photovoltaic cell" modules—as both can affect your system's performance.


Once you've started confirmed that your location is a workable site for a solarpower system, it's time to locate the knowledge on how to build the system. WindEnergy SolarEnergy provides you with two links below which can help you gain the information you need to build your own "home solar energy" system. Take a few minutes to review the sites and decide which is right for you.

SolarEnergy Basics

Solar panels installed on a home in Colorado.

Solar is the Latin word for sun—a powerful source of energy that can be used to heat, cool, and light our homes and businesses. That's because more energy from the sun falls on the earth in one hour than is used by everyone in the world in one year. A variety of technologies convert sunlight to usable energy for buildings. The most commonly used solarenergy technologies for homes and businesses are solar water heating, passive solar design for space heating and cooling, and solar "Photovoltaic Cell" for electricity.

Businesses and industry also use these technologies to diversify their energy sources, improve efficiency, and save money. SolarEnergy "photovoltaic cell" and concentrating solarpower technologies are also being used by developers and utilities to produce electricity on a massive scale to power cities and small towns.

Concentrating Solar Energy Power 

These technologies harness heat from the sun to provide electricity for large power stations.

Passive SolarEnergy Technology 

These technologies harness heat from the sun to warm our homes and businesses in winter.

Global Green - WindEnergy - SolarEnergy - Location

Picking the Best Location for a Wind Turbine

Where you choose to build your wind turbine is important. Remember that if nearby houses, tree lines and silos obstruct the full force of the wind from your wind turbine, you will not be able to generate as much power.

Also keep the following in mind:

• Wind speeds are always higher at the top of a hill, on a shoreline, and in places clear of trees and other structures.
• Remember that trees grow over the years; wind turbine towers do not.
• Inform neighbours of your plans to avoid conflict later on.
• Be courteous. Keep the turbine as far away from neighbours as possible. 250-300 m away is typical.
• Check with the local government for any other bylaws and regulations about zoning.

Wind speeds tend to be higher on the top of a ridge or hill, and for that reason it is a good idea to locate wind turbines at hilly locations. Just remember to keep your turbine away from high turbulence. Neighbours must also be taken into consideration when picking a spot to build your turbine. The farther your wind turbine site is from neighbouring houses, the better.

Do not expect your wind turbine to generate the same amount of power all the time. The wind speed at a single location may vary considerably, and this can have a significant impact on the power production from a wind turbine (Figure 3). Even if the wind speed varies by only 10%, the power production from a wind turbine can vary by up to 25%!

SolarEnergy - "Photovoltaic Cell" System

Many PV "Photovoltaic cell"s, connected in series, form a PV module; several modules attached to a frame form a solarenergy electric panel. A panel can power a stand-alone system, simply and cost-effectively generating electricity away from the power lines, or it can be connected to the power grid, allowing the owner to sell the electricity generated.

Components of Solarenergy Electricity Generation

The basic components of a PV "Photovoltaic cell" system (Figure 7) include:

• PV modules which are a group of cells that generate an electric field by absorbing sunlight, resulting in direct current (DC) electricity.
• An inverter which converts the DC electricity from the PV modules into the alternating current (AC) electricity is used in the power grid and is required by most electrical appliances.

Most PV "Photovoltaic Cell" systems in operation use one centralized inverter to convert electricity from multiple panels. These large inverters involve power loss and can be noisy.

Microinverters, a new technology, attach directly to each solar module in the power system.
