Energy demands in a commercial or a residential setting are increasing daily. Therefore, people have turned attention to a renewable and free source of electricity, the sun.
Solar energy is the electricity obtained from sunlight with the help of photovoltaic systems. The generated power can therefore be used to power businesses, homes, or cars.
The world is slowly turning to green energy, and the solar option has dominated the market because it is friendly to the ecosystem. Solar energy offers mutual benefits to both the consumers and the environment.
Exploiting the sunlight renewably does not harm the environment, and it is the cheapest way of harnessing power.
Solar Power Generation Concept
The idea of exploiting the sun to generate solar energy has been there for years, with the first voltaic cell being designed in the 19th century, whose efficiency was just 1%.
The early harnessing attempts were fueled by the cheapness in the form of energy because it is easily renewable without incurring any extra cost. The moment you purchase the solar panels, successive power production will be free.
Since the voltaic cells do not emit carbon into the air, the environment is free of contamination, and so no renewable measures should be instituted. Therefore, solar power generation has been there, and it is bound to dominate the power industry for years.
It takes a short while to harness energy from the sun and cannot be compared to the annual barrels of oil that could be consumed plus the tons of carbon that could be emitted annually.
Solar panels have solar cells comprised of semiconductors and also called photovoltaic cells. The cells transform sunlight into electrical power. Sunlight strikes the cells, and electrons dissociate from atoms and freely move through the cell, thereby producing electricity.
Domestic solar cells are efficient because they can convert approximately 20% of the light that hits them into electricity. The commercial panels are more efficient because their conversion can exceed 40%.
Technology is under rapid advancement in solar energy harnessing because better systems are expected to enter the market, and the prices will drop.
The installation charges of a solar system should not be overrated because the repayment period is short as a lot is saved on electricity bills as well as other government aids.
Solar systems improve the home value, and potential buyers come more often trying to trigger a deal as compared to the ones without. Growth in technology and increased installations will drastically lower the prices because the materials’ value will have lowered as well as the economies of scale.
Since the solar panels came to the market, the prices have been decreasing, and more is expected going forward. This will encourage more clients to turn to solar energy until everyone shifts completely.
A short while after installation, maintenance might not be needed, maybe checking frequently to ensure the panels are clean and are facing direct sunlight. The photovoltaic cells can last for almost 30 years or even more before requiring maintenance, maybe some repair out of physical damage.
Exposure to Sunlight
Solar cells do not necessarily need direct exposure to sunlight to produce power. However, they are at maximum efficiency if the sun rays are shining brightly. Even during the winter or cloudy days, electricity is produced, and so you can rely on solar energy.
However, the solar cells cannot produce power at night, but the day’s generation is usually sufficient. In case the panels produce extra energy, you can sell it to the national grid to make up for the cost of the battery storage system.
Solar power should be more valuable because production happens only during the day.
