The most commonly used solar technologies for homes and businesses are solar photovoltaic energy for electricity, passive solar design for space heating and cooling, and solar water heating. Companies and industry use solar technologies to diversify their energy sources, improve efficiency and save money. Solar radiation produced by solar energy is abundant all over the world, but some places are more suitable for photovoltaic solar panels than others. For example, it makes more sense to use the energy of the sun in places where the sun shines all year round, such as in deserts.
Where there is more sun, there are more possibilities to add solar technologies to the utility energy mix. Some of the countries with the most sunlight make the list of top 10 solar capacities, such as Australia and India, but there is certainly untapped potential in Africa and South America. Many of the countries in the world that have the most installed solar energy per capita do not necessarily have high levels of solar insolation. Government and state incentives play an important role in making solar energy affordable.
For solar energy to succeed, governments must support the shift from the energy industry to renewable energy. A good example of this is the state of New Jersey. In recent years, China's solar panel capacity has increased exponentially. It has grown to become the largest solar market in the world and it is estimated that by 2024, China will have 370GW of solar energy installed, twice what the U.
S. UU. While this growth is impressive and admirable, China will have to continue to ease its dependence on coal power generation to be seen as a true leader in renewable energy. Europe has been encouraging the growth of renewable energy for years and plans to boost renewables to improve its post-COVID-19 economic recovery. In addition, Germany, Italy, the United Kingdom and France currently occupy the top positions in terms of capacity of solar parks or agrovoltaic systems.
To reduce CO2 emissions, European Union countries plan to extract most of their electricity from renewable sources by 2050, with solar energy as the main source of energy. In addition to the federal solar tax credit, individual states offer local incentives to install residential solar systems. They are also beginning to adopt solar energy for their low-cost energy production and job creation, and are beginning to incorporate solar power plants into their energy mix. California remains at the forefront of growth of solar photovoltaic systems in the U. And it is one of the best states to install solar energy.
But now, other states are catching up, including Texas, Utah, Florida, New York, Massachusetts and Rhode Island. It is projected that by 2024, there will be an average of 1 solar installation per minute in the US. China is easily the world's largest market for solar energy, and as the country develops plans to neutralize its carbon emissions by 2060, activity is likely to accelerate further in the coming decades. In the same year, solar power generation totaled 223.8 terawatt hours (TWh) in the country. China's largest single solar project is the Hainan Hydropower Huanghe Solar Park (2.2 GW) in Qinghai Province. However, installed solar capacity in Japan could approach 100 GW by 2025, depending on government policies and lower costs.
Competitive auctions have boosted the industry in recent years, and the German government recently proposed to increase its solar installation target by 2030 to 100 GW, as it targets a 65% share of renewables in its energy mix by the end of the decade. The country's largest solar project to date is the 187 megawatt (MW) Weesow-Willmersdorf facility northeast of Berlin, which has been developed by German company EnBW. Government targets include 450 GW of renewable energy capacity by 2030, and solar energy is expected to be central to this ambition. By 2040, the IEA expects solar energy to maintain a share of approximately 31% of India's energy mix under current policy ambitions, compared to less than 4% today. The agency cites the “extraordinary cost competitiveness of solar energy in India as a driving force for this change” which surpasses existing coal-fired energy by 2030 even when combined with battery storage. Entergy Mississippi will soon start operations on its 100MW Sunflower Solar Station.
The amount of sunlight that reaches Earth's surface in an hour and a half is enough to manage all global energy consumption for an entire year. Solar technologies convert sunlight into electrical energy using photovoltaic (PV) panels or mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage. Obviously there can be a substantial investment in installing a solar water heater but doing some math can show that it can be a cost-effective idea when calculating how much it would cost over 20 years or more. On a much larger scale a large bank of solar panels can charge an entire bank of storage batteries that can power almost any 120-volt AC device until it serves an entire house. Solar cookers also allow villagers to devote themselves to education business health or family during time that was previously used collecting firewood. The availability and intensity of solar radiation on Earth's surface varies depending on time of day and location.
This Solar Power Generation System (SEGS) generates more than 650 gigawatt-hours (GWh) of electricity each year. The total amount of solar energy incident on Earth far exceeds current and anticipated global energy needs.
