There is no solar energy at night, so a large battery bank is needed.
Solar energywill be accessible as long as we have the sun, so sunlight will be available to us for at least 5 billion years, when, according to scientists, the sun will die. The most reliable solar panel manufacturers offer a warranty of 20 to 25 years. In addition, since there are no moving parts, there is no wear and tear.
The inverter is usually the only part that needs to be changed after 5 to 10 years, since it works continuously to convert solar energy into electricity and heat (photovoltaic solar energy). In addition to the inverter, the cables also need maintenance to ensure that the solar energy system operates at maximum efficiency. So, after covering the initial cost of the solar system, you can expect to spend very little on maintenance and repair work.

This includes paying for the solar panels, the inverter, batteries, wiring and installation. However, solar technologies are constantly developing, so it's safe to assume that prices will fall in the future. While pollution related to solar energy systems is much lower compared to other energy sources, solar energy may be associated with pollution. The transportation and installation of solar systems have been associated with the emission of greenhouse gases.
The energy produced by solar panels is clean, renewable and has zero emissions. Solar energy does not contribute to greenhouse gases or fossil fuels, unlike other oils and carbons. The other side is that, while a solar panel system may not be financially cost-effective, it does reduce the burden on the local electricity grid. According to Northwestern University's Qualitative Reasoning Group, most solar panels in people's homes convert only 14% of available energy into energy.
Being able to sell their energy to the government for cash entices homeowners to switch to solar energy. Because the price of solar panels is becoming more affordable, there may come a time in the future when the government reduces the rebates and incentives they offer. Although solar panels are responsible for greenhouse gas emissions, they have nowhere near the impact on the atmosphere of burning fossil fuels. There is a race to make solar panels affordable while maintaining the quality of solar panels.
However, there are several major disadvantages that have historically prevented solar energy from becoming a major energy provider. Technology in the solar energy industry is constantly advancing, and improvements will intensify in the future. Installing solar panels in your home could allow you to be completely energy independent. Solar power plants produce no air, water or noise pollution and do not emit greenhouse gases (large scale power plants can disrupt local plants and wildlife because of their size, but compared to fossil fuels, they still have a smaller environmental footprint).
In most cases, it's smarter to use solar energy during the day and take energy from the grid at night (you can only do this if your system is connected to the grid). The other method, which is actually very ingenious, uses solar energy produced to create methanol from carbon dioxide instead of electricity. Solar energy can be used to produce electricity in areas without access to the energy grid, to distill water in regions with limited supplies of clean water, and to power satellites in space. Unless you want to pay more to have your system dismantled, unwired and transported elsewhere, solar panels get stuck in one position.
Land use by solar fields can be massive and, unlike wind energy, sharing land for agricultural use is not an option. .
