This article is about generation of electricity using solar energy. For other uses of solar energy, see Solar energy. Average insolation. Note that this is for a horizontal surface, whereas solar panels are normally propped up at an angle and receive more energy per unit area, especially at high latitudes. Potential of solar energy. ![]() The small black dots show land area required to replace the world primary energy supply with solar power. Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power. Concentrated solar power systems (Unified Solar) use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam.

This short eBook tries to answer the most common questions I was asked during my years as a renewable energy engineer. When I first started installing solar power systems I. ![]() Photovoltaics convert light into an electric current using the photovoltaic effect. Most solar installations would be in China and India. As the cost of solar electricity has fallen, the number of grid- connected solar PV systems has grown into the millions and utility- scale solar power stations with hundreds of megawatts are being built. Solar PV is rapidly becoming an inexpensive, low- carbon technology to harness renewable energy from the Sun. Commercial concentrated solar power plants were first developed in the 1. The 3. 92 MW Ivanpah installation is the largest concentrating solar power plant in the world, located in the Mojave Desert of California. Mainstream technologies. Long distance transmission allows remote renewable energy resources to displace fossil fuel consumption. Solar power plants use one of two technologies: Photovoltaics. The first solar cell was constructed by Charles Fritts in the 1. Following the work of Russell Ohl in the 1. Gerald Pearson, Calvin Fuller and Daryl Chapin created the silicon solar cell in 1. For practical use this usually requires conversion to certain desired voltages or alternating current (AC), through the use of inverters. Modules are wired together to form arrays, then tied to an inverter, which produces power at the desired voltage, and for AC, the desired frequency/phase. In certain applications such as satellites, lighthouses, or in developing countries, batteries or additional power generators are often added as back- ups. Such stand- alone power systems permit operations at night and at other times of limited sunlight. Concentrated solar power. Contrary to photovoltaics . Various techniques are used to track the sun and focus light. In all of these systems a working fluid is heated by the concentrated sunlight, and is then used for power generation or energy storage. The receiver is a tube positioned right above the middle of the parabolic mirror and is filled with a working fluid. The reflector is made to follow the sun during daylight hours by tracking along a single axis. Parabolic trough systems provide the best land- use factor of any solar technology. This has the advantage that flat mirrors can be used which are much cheaper than parabolic mirrors, and that more reflectors can be placed in the same amount of space, allowing more of the available sunlight to be used. Concentrating linear fresnel reflectors can be used in either large or more compact plants. The advantages of Stirling solar over photovoltaic cells are higher efficiency of converting sunlight into electricity and longer lifetime. Parabolic dish systems give the highest efficiency among CSP technologies. Power towers are more cost effective, offer higher efficiency and better energy storage capability among CSP technologies. The combined form of generation may enable the system to modulate power output as a function of demand or at least reduce the fluctuating nature of solar power and the consumption of non renewable fuel. Hybrid systems are most often found on islands. CPV/CSP system. A novel solar CPV/CSP hybrid system has been proposed, combining concentrator photovoltaics with the non- PV technology of concentrated solar power, or also known as concentrated solar thermal. Another example is the Yazd power station in Iran. PVT system. Hybrid PV/T), also known as photovoltaic thermal hybrid solar collectors convert solar radiation into thermal and electrical energy. Such a system combines a solar (PV) module with a solar thermal collector in an complementary way. CPVT system. A concentrated photovoltaic thermal hybrid (CPVT) system is similar to a PVT system. It uses concentrated photovoltaics (CPV) instead of conventional PV technology, and combines it with a solar thermal collector. PV diesel system. It combines a photovoltaic system with a diesel generator. Solar cells use only the high frequency part of the radiation, while the low frequency heat energy is wasted. Several patents about the use of thermoelectric devices in tandem with solar cells have been filed. However, development of solar technologies stagnated in the early 2. Other efforts included the formation of research facilities in the United States (SERI, now NREL), Japan (NEDO), and Germany (Fraunhofer. This was surpassed by the 5. MW Solar Star complex. The current largest photovoltaic power station in the world is Longyangxia Dam Solar Park, in Gonghe County, Qinghai, China. World's largest photovoltaic power stations as of 2. Name.

The 3. 77 MW Ivanpah Solar Power Facility, located in California's Mojave Desert, is the world. Other large CSP plants include the Solnova Solar Power Station (1. MW), the Andasol solar power station (1. MW), and Extresol Solar Power Station (1. MW), all in Spain. The principal advantage of CSP is the ability to efficiently add thermal storage, allowing the dispatching of electricity over up to a 2. Since peak electricity demand typically occurs at about 5 pm, many CSP power plants use 3 to 5 hours of thermal storage. Located southwest of Las Vegas. Solar Energy Generating Systems.

Process improvements and a very large boost in production have brought that figure down to 6. February 2. 01. 6, according to data from Bloomberg New Energy Finance. And in sunny Dubai large- scale solar generated electricity sold in 2. Thus, capital costs make up most of the cost of solar power. Operations and maintenance costs for new utility- scale solar plants in the US are estimated to be 9 percent of the cost of photovoltaic electricity, and 1. Also, Renewable portfolio standards impose a government mandate that utilities generate or acquire a certain percentage of renewable power regardless of increased energy procurement costs. In most states, RPS goals can be achieved by any combination of solar, wind, biomass, landfill gas, ocean, geothermal, municipal solid waste, hydroelectric, hydrogen, or fuel cell technologies. The electrical energy generated is sold in units of kilowatt- hours (k. Wh). As a rule of thumb, and depending on the local insolation, 1 watt- peak of installed solar PV capacity generates about 1 to 2 k. Wh of electricity per year. This corresponds to a capacity factor of around 1. The product of the local cost of electricity and the insolation determines the break even point for solar power. The International Conference on Solar Photovoltaic Investments, organized by EPIA, has estimated that PV systems will pay back their investors in 8 to 1. Fifty percent of commercial systems in the United States were installed in this manner in 2. No longer are renewable power sources like solar and wind a luxury of the rich. They are now starting to compete in the real world without subsidies. In 2. 01. 4, prices continued to decline. The Sun. Shot Initiative modeled U. S. Costs for utility- scale systems in China and India were estimated as low as $1. By late 2. 01. 1, the fully loaded cost was predicted to fall below $0. Wh for most of the OECD and to reach $0. Wh in sunnier regions. These cost levels are driving three emerging trends: vertical integration of the supply chain, origination of power purchase agreements (PPAs) by solar power companies, and unexpected risk for traditional power generation companies, grid operators and wind turbine manufacturers. For example, in Germany, with electricity prices of 0. Euro/KWh and insolation of 9. KWh/KW, one KWp will save 2. Euro per year, and with an installation cost of 1. Euro/KWp the system cost will be returned in less than 7 years. The electricity is sold, and at other times when energy is taken from the grid, electricity is bought. The relative costs and prices obtained affect the economics. Energy pricing and incentives. The policies are implemented to promote national energy independence, high tech job creation and reduction of CO2 emissions. Three incentive mechanisms are often used in combination as investment subsidies: the authorities refund part of the cost of installation of the system, the electricity utility buys PV electricity from the producer under a multiyear contract at a guaranteed rate (), and Solar Renewable Energy Certificates (SRECs)Rebates. While the investment subsidy may be simpler to administer, the main argument in favour of feed- in tariffs is the encouragement of quality.
