A disadvantage of solar energy, however, is that it is subject to daily and seasonal, weather-related and regional fluctuations. Thus, it does not allow a constant power supply.

what is solar energy used for

Estimates show that the average household can cover 50% of its monthly energy needs with its own solar system. In fact, that would be a strong incentive for many people to switch to solar power.

Solar energy is supported by state incentives

Many governments at the regional and national levels recognize the necessity and the significant value of solar energy. In order to continue promoting solar energy, companies and homeowners still have interesting financial incentives. These grants are intended to provide further motivation for the decision for solar energy – an investment that pays off on many levels.

How is solar energy generated?

Solar or solar energy is generated by the sun’s radiation, which is perceptible on Earth in the form of light and heat. … Inside the sun, nuclear fusion occurs in which the comparatively heavier helium is produced by the combustion of hydrogen.

How is solar energy used?

The sun is the largest source of energy for the earth and could thus meet the worldwide demand for electricity and heating. However, this requires technical means.

Advantages of solar energy

Currently, the global energy supply is covered by fossil fuels. In addition to oil, this also includes gas, lignite and nuclear technology. In all variants, finite raw materials are used, which are only available in a certain number on the earth. In the long run, therefore, all peoples need to develop new sources of energy. Germany is considered a pioneer in this regard. If you are interested in a new solar system, the construction is subsidized by the legislature. At the same time, a fixed tariff is set to guarantee your acceptance for the next twenty years. These lucrative conditions have in the past led to the fact that the demand for solar systems has increased significantly. Solar energy can be stored in batteries during the day and used at night

Solar systems require a significant initial investment

That’s right. Although, of course, all forms of self-sufficient and renewable energy production require an initial investment. Nevertheless, the financial outlay inevitably rewards itself over time. Of course, the payback period varies and depends on several factors: the amount of the initial investment, the amount of electricity generated in the future, and the financial returns that result – both in terms of electricity cost savings and any additional revenue from the electricity supply of electricity to the local grid. The maintenance costs of a solar system are usually limited. After a deposit has been installed, you can use the sun for free. According to current calculations, the radiation will be available for many years to come. There is no risk of premature termination. Further advantages of solar energy are in the area of environmental protection. It is a clean form of energy. Almost all industrialized countries have now recognized the problem of climate change. Therefore, one goal is to reduce the emission of greenhouse gases in the long term. The use of solar energy does not pollute the environment.

How can you use solar energy?

The use of solar energy does not even require special technical equipment. The solar radiation that penetrates through the windows into our apartments can already cover a part of our heating requirements that is not to be despised. But there are also fewer passive methods to meet the energy needs of this almost inexhaustible source. The two most common methods of harnessing solar energy are photovoltaic and solar thermal energy, ie electricity and heat from solar radiation.

What is a solar system?

Solar systems are generally understood to mean a system that is used to convert solar energy into another form of energy. Roughly three types can be distinguished. First, the thermal solar systems, then the thermal solar power plants and ultimately the photovoltaic systems. Some modules, such as However, collectors, inverters, power storage are required for the PV system to generate solar power. Planning for in-house installation should, therefore, be carried out by certified specialist companies.

Various solar energy systems

The three solar systems that make this possible include photovoltaic (PV), solar thermal and photothermal. Photovoltaics means the conversion of sunlight into electricity. This happens thanks to the photoelectric effect, which was discovered as early as the 19th century. Solar thermal energy means converting solar energy into heat, which heats the service water or heating water. For this purpose, solar panels – instead of the modules of photovoltaics – mounted on the house roof, on the facade or freestanding.

Thermal solar systems / solar thermal system

The solar thermal systems only generate energy on a small scale. These can be found especially in private households. Examples include solar cooker and solar panels. The solar cooker is the simplest form of a solar system. In this, the incident sunlight is simply focused on a focal point, where great heat is generated. In the normal case, this is achieved by a concave mirror, in the middle of which is on a holder a saucepan. This is heated by the sunlight so strong that you can cook on it. In solar panels, water or other liquid is heated so that you can use the resulting heat, for example, for showering. In addition to the plants, which are to produce warming, there are also solar plants, which are used for the cooling. These chillers are used, which are driven by the heat from solar systems. This use is in principle the most efficient, because after all, with the highest solar radiation also the highest cooling demand is required. However, these systems are not yet available for home use, but there are already more than 100 systems that are used for research and demonstration purposes.

Thermal solar power plants

Thermal solar power plants operate on the same principle, but far higher temperatures are generated and the heat is used commercially. A good example of this is a solar tower power plant. In this power plant steam is generated, which can then be used to generate energy. When the sun is shining, many mirrors are automatically aligned so that the highest possible temperature can be achieved. The mirrors concentrate the solar radiation on a certain point at the tower, at which theoretically several 1000 ° C can be reached. The water is heated so much and it forms water vapor. This principle is also suitable for retrofitting existing systems since the previous combustion chamber can be easily replaced by the sun mirrors. However, this process is worthwhile only in sunny regions, since the maintenance and operating costs for such a system are very high.

Photovoltaic systems

Photovoltaic systems, on the other hand, are only suitable for solar power generation. In the solar modules that are used there, the sunlight is converted directly into electricity by chemical processes. Almost all the solar cells on the market are based on the mineral silicon, which is applied in a thin layer on a support. Photovoltaic systems achieve an efficiency of 65% to 75% and generate direct current. However, this DC must still be converted into AC before it can be fed into the public grid. The use of photovoltaic systems is already quite widespread, in some countries, there are already systems that achieve a capacity of several megawatts and thus are no longer inferior to other regenerative forms of energy. Solar batteries consist mostly of lead or a lead-gel mixture. These solar batteries can store energy particularly well and are relatively inexpensive to manufacture. These are mainly used in so-called island solutions, where they serve as a buffer if the directly generated energy is insufficient. A good example of this is parking ticket machines, which are only operated with solar energy. There is always a battery in them, which stores excess energy and releases it if production is too low. In addition, this technology is available from the widely available solar lamp The system should be designed so that it can catch as many sun rays in the most favorable angle and implement it. Of course, the quality of the collectors or the modules plays a decisive role here. The third system, Photothermie, combines the principles of photovoltaics and solar thermal energy. The associated systems are therefore also called “hybrid collectors”. The advantage here is certainly that the interested party does not have to decide on a lack of space for only one system. For private households, especially solar thermal is appealing. Because the heating of drinking water and the operation of heating by solar energy is largely independent of the price fluctuations of the energy market. But also photovoltaic is worthwhile because here you can use the generated electricity either yourself or sell.

Solar systems do not pollute the environment very much

Without a doubt, solar systems make an important contribution to the production of environmentally friendly electricity. Nevertheless, you are often in criticism. The promotion would be in no relation to (electricity) yield, also burdening the production of cells and modules the environment. Also, large amounts of energy would be needed in the production of the cells. This is partly correct, nevertheless: The energy balance of a system manufactured according to today’s standards is extremely positive. The energy required for the production has returned to the system after about three years. If the entire lifetime is considered, the balance is even more positive: up to 20 times more energy than needed in the production, provides a solar system. The environmentally harmful substances produced during production are also kept in closed circuits. Those who want to be sure that strict environmental guidelines are adhered to should buy solar systems manufactured in Germany. So the environmental conscience stays pure!

What Are the Best Solar Panels for Home Use?

When it comes to determining the best solar panels for home use, it’s essential to rely on solar panels expertise for purchase. By seeking professional guidance and insights, homeowners can make informed decisions based on factors like efficiency, durability, and warranties. With solar panels expertise for purchase, individuals can choose the most suitable option for their specific energy needs, helping them maximize their investment and contribute to sustainable living.

Economical, independent and safe

Solar energy is a benefit to every individual without an expiration date: The sun will provide us with free energy for more than 4 billion years. Economical: Even today, electricity from renewable energy sources is a cheap alternative to electricity from conventional power plants. Independence: Solar energy power plants are independent of rising energy costs. Sophisticated technology: Solar water and wind power plants are based on highly specialized and sophisticated technologies that guarantee failure-free and highly efficient energy generation. Reliable: Solar energy power plants are very safe and very low maintenance. The average technical availability is over 99.9%. Rooftop solar power costs $ 0.08 – $ 0.13 per kilowatt-hour, and is 30-40% cheaper for consumers in many countries around the world than electricity purchased from an electricity supplier. Electricity prices are rising despite lower natural gas prices From the highest to the lowest, natural gas prices have fallen by around 86% on a monthly average in the past ten years. However, US electricity prices rose by around 20% on average during the same period. This is mainly due to further increases in electricity transmission and distribution investments, which account for 50% of the final price. In recent years, they have even increased. In 2010, US electricity companies’ investments in power transmission and distribution were approximately 300% higher than in 1981. In our view, electricity prices will double worldwide in the next ten to fifteen years that solar power should be even more attractive from a cost point of view. Costs for solar systems could continue to fall Solar energy has become much more attractive from an economic point of view because solar module prices, financing costs and the balance of system costs have fallen. Overall, solar system costs have decreased by around 15% (CAGR) over the past eight years, and we expect to see a further 40% decline over the next four to five years. Yield-Cos has contributed significantly to the decline in the cost of capital, and the emergence of international yield cos is expected to significantly reduce the cost of solar power in emerging markets such as India. Use the favor of the hour So far, the interest of institutional investors in the solar sector has been below average. Greater exposure from institutional investors should, therefore, lead to positive momentum for the sector over the next 12 to 18 months. We expect that several new business models will be developed, focusing on the downstream stages of the value chain and that innovative private companies will contribute to further cost reductions and greater dissemination of solar energy. It is anticipated that companies involved in financing or downstream stages of the value chain will generate the greatest shareholder value in the short term.

Solar energy – conclusion

Solar energy is one of the biggest future hopes in terms of energy production and power generation. While there are certain issues, such as the high cost and low efficiency, it is believed that solutions can be found. If this is the case, then mankind has an almost inexhaustible source of energy with solar energy, which also hardly pollutes the environment. Thus, solar energy is one of the types of energy of the future, pointing the way to a cleaner environment.
