In our world today we have many problems, such as an ever growing problem that we face, which is the use of electricity, in that matter we face many problems locally and globally. If electricity was not used locally sparingly/wisely, the bill price would be very high and families would have to use their hard-earned money to pay the bills of high electricity consumption. And so families would have to spend a lot of money every year just to pay the bills. The problem that people face globally is that as more money is spent and with the problem of inflation, bill prices will only increase and therefore become more expensive. Solar power is energy efficient, which means that solar power can never run out as long as it is installed properly. Solar power cells are a source of electrical energy that converts a powerful energy source such as the sun into electricity, using its energy to create electrical currents within the solar panel. Solar panels produce electricity using technology called “Solar Photovoltaics (PV)”. Diagram of how solar panels generally work in a home.

Solar panels transfer energy through an inverter, to the electrical panel and then back to the electricity grid. Without the inverter all this would not be possible as the energy collected by the panels is direct current and therefore cannot be used. Inverters convert DC electricity into AC electricity so they can actually be usable. Not only do they… half the paper… and system you need. And with these options there are choices to make, whether or not a person prefers quality but at a price or, at best, cheap and decent. Although installing solar panels can be expensive (around $3000 depending on the company), the long-term savings a person can save outweigh the thought of paying quite a bit of money to have solar panels installed. Solar panels are environmentally friendly. They are the very essence of the definition "eco-friendly". Typical electricity uses fossil fuels, which are NOT renewable, which also means that the earth's resources are diminishing/depleted, normally using fossil fuels would require burning and therefore releasing harmful emissions into the environment. Solar panels use the sun's energy, which is a very reliable, renewable and therefore environmentally friendly source.
