What makes a solar panel work
Our sun is a nuclear reactor in its normal state. It emits energy in the form of tiny packets called photons, which travel 93 million miles from the sun to Earth in about 8.5 minutes. Each hour, sufficient photons strike our globe to generate enough solar energy to theoretically meet the world’s energy requirements for a whole year.
At the moment, solar energy accounts for less than 5% of the energy utilized in the United States. However, as solar technology advances and the cost of going solar continues to fall, our ability to harness the sun’s abundant energy is increasing.
In 2017, the International Energy Agency reported that solar energy had surpassed all other forms of energy to become the world’s fastest-growing source of energy – the first time solar energy’s growth had surpassed that of all other forms of energy. Since then, solar has continued to expand and set new milestones on a global scale.
How do photovoltaicwork?
Solar panels generate electricity by absorbing sunlight via photovoltaic (PV) cells, which are often installed on the roof of a house. The panels convert the sunlight to direct current (DC) energy, which is then sent inside the house to an inverter, which transforms it to alternating current (AC) energy, which then runs through the home’s electrical panel, supplying electricity to any equipment. Any extra electricity generated will be routed to the grid, which will give you the electricity you require if you consume more than the panels generate.
That is a great deal to take in at once, so here is your four-step overview:
- Solar panels absorb solar energy and convert it to direct current power.
- Inverter technology converts the direct current electricity generated by your s to alternating current electricity (AC electricity is used by most home appliances).
- Your home is wired for electricity, which powers electronic equipment and devices.
- Any excess energy generated by the solar panels is fed back into the grid.
Solar panel advantages
Now that you understand what they are and how they work, we can explain why you should care.
Source of renewable energy: Solar energy will be available as long as the sun exists, which experts estimate to be at least five billion years. It is genuinely a renewable energy source that produces no greenhouse emissions, pollutes the environment, or generates noise.
Electricity bills are reduced: Because solar panels will provide a portion of your energy needs, your total electricity expenses will decrease. Additionally, you can earn money by selling any excess electricity back to the grid. Additionally, when solar panels are installed, you can still change your gas and electricity suppliers.
Timing: In the afternoons and evenings, when people are at home, household energy consumption requirements are often higher. This is ideal because solar energy is at its peak production at those periods. Nota bene: solar panels do not function at night.
Low upkeep: Solar panels require little maintenance – only a few times a year cleaning. Warranties are typically 20-25 years, and the inverter needs replacement after ten years.
