The Benefits of Solar Power
Concentrating solar-thermal power (CSP)
Solar Power; Concentrating solar-thermal power (CSP) is a type of renewable energy technology that converts heat from sunlight into electricity. It can be used in many applications. These include chemical processing, mineral processing, water desalination, and enhanced oil recovery. In addition, CSP can also be combined with energy storage technologies.
Concentrating solar-thermal power is an important technology that has proven itself to be reliable and efficient. However, cost increases have impeded its deployment. As a result, the technology needs to be further developed.
The US Department of Energy has awarded $24 million to 10 research teams. The goal of these groups is to develop commercially viable technologies. They are focused on increasing the efficiency and reliability of CSP plants.
Several new technologies are in development. These include thermal energy storage tanks, concentrating photovoltaic panels, and molten salt storage systems. Although they are not yet deployed at large scale, each of these technologies has a strong potential for widespread use.
Solar thermal power plants operate at high temperatures. This is due to the fact that they concentrate the direct beam of sunlight and capture the heat. The thermal energy from the sun is then stored and then spun into a turbine to generate electricity. A similar process is used with wind turbines.
There are several factors that determine the overall efficiency of a CSP plant. For example, the amount of land it will need and its location. In addition, there are certain criteria that must be met to qualify for installation. Some of these include permanent water, slope greater than two percent, and security margins of up to 10 kilometers.
Costs of concentrating solar-thermal power are higher than those of onshore wind power. However, the LCOE, or life cycle cost of electricity, from these technologies has declined over the last few years.
The LCOE of a new CSP plant will fall by 20% for every doubling of installed power. Once the total installed capacity reaches 10 GW worldwide, the LCOE will drop to half. If a LCOE of 10 cents per kilowatt-hour is reached, it would be comparable to the cost of fossil fuels.
Photovoltaic (PV) panels
Photovoltaic (PV) panels are a clean, green source of power. They are used for a variety of purposes, from powering homes to large commercial businesses. Their benefits include low maintenance costs, long service life, and low noise output.
PV cells are semiconductor materials that capture sunlight and convert it into electricity. Several technologies are available, including silicon, polycrystalline, and thin film. Currently, monocrystalline silicon is the most advanced. However, it is more expensive to produce. The cost of solar photovoltaics has come down as the industry has scaled up manufacturing.
A single cell produces about one watt of power. Multiple cells are connected in series to generate a higher voltage. Individual PV cells are often thinner than four human hairs.
Each cell is sandwiched between protective materials to prevent damage. These materials may include glass, plastic, or even a combination of both.
Solar photovoltaic cells are used to produce power for residential applications, such as powering wristwatches and calculators. Larger photovoltaic systems are also used to power electrical grids.
Photovoltaic systems have been around for more than a century. In fact, the first PV device was manufactured by Bell Labs in 1958. Today, more than 100 countries are using this technology to generate power.
A PV panel can be ground-mounted or placed on a rooftop. Depending on the application, the module’s location impacts its performance. For example, the panel will generate more energy when the sun is high in the sky, but less when it is low.
A good photovoltaic panel can last for more than a hundred years. This makes it a very economical and environmentally friendly choice for residential use. It is especially beneficial in suburban neighborhoods.
PV installations are inexpensive to install and operate. Installations require minimal maintenance after the initial set-up. Fortunately, prices are expected to continue to decline over the next few years. Moreover, solar power is now a viable alternative for many consumers.
There are also numerous benefits to adopting renewable sources of energy. Besides, it helps make our nation’s electricity system more resilient.
