The rise in CO2 levels and global warming has raised the alarm in the need to look for alternative energy sources that don’t leave an environment impact. Even if government policies don’t support moving the country into a more environmentally friendly policies, we can take action on our own and do what we can to reduce our own environmental impact and reduce our dependence on fossil fuels. Solar Panels, cheap alternative way to produce electricity for the home, is one-step in the right direction for reducing our dependence on foreign fuels, which individuals can take on their own. Solar panels are typically used to produce electricity and are also called photovoltaic cells. A photovoltaic panel is an assembly of interconnected photovoltaic cells or solar cells. Solar providers near me crystalline cells are a crystalline-based structure that is able to take sunlight and convert it into electricity. The more photovoltaic cells that are on a panel, the more electrical current can be produced. In order for the solar panels to be useful in practical applications of an alternative electrical source, they must be constructed in a certain way. The solar cells must be:
- Electrically connected to each other as well as the rest of the system.
- Protected from physical damage from situations such as hail, wind and snow, because some types of solar cells are brittle.
- Protected from moisture such as rain and humidity so the metal contacts don’t get corroded, or the cells don’t form an oxide layer, which will decrease performance.
- Insulated electrically to protect against rainy conditions.
- Sturdily mounted.
Since sunlight is really made from a huge range of electromagnetic frequencies, solar cells only are able to convert a small percentage of sunlight into useable electricity. Solar cells can now be created to maximize their efficiency by using the different frequency ranges of sunlight, yet that would require an additional device to separate the different frequencies and shine them on the appropriate group of solar cells that are designed to specifically convert that frequency of sunlight. It is estimated that this technique would increase the efficiency of solar cells by 50%. Currently without this method, solar cell efficiencies are in the range of 5 to 19%, which is actually a higher efficiency than solar panels produced in earlier years. There are new processes being researched, which will concentrate the solar light to the photovoltaic modules and can raise the efficiency up to 30%. With today’s technology, the average solar panel can produce about 140 watts of electricity. Solar panels create electricity from an unlimited source, the Sun, which is a major benefit for using them. When the Sun stops shining, not having electricity will be the least of your concerns.
