What does a solar panel do
Our sun is a nuclear reactor in its normal state. It emits tiny packets of energy called photons, which travel 93 million miles in about 8.5 minutes from the sun to the Earth. 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.
How dogenerate electricity for your home?
Solar panel systems provide usable electricity for your home in the following manner:
Photovoltaic cells collect sunlight and convert it to direct current power.
Each’s solar cells are responsible for the majority of the work involved in generating power. Your solar panels generate an electrical current via the photovoltaic effect.
Solar inverters convert DC electricity from your solar modules to AC electricity, which is used by most home appliances
When DC electricity travels through your solar inverter, it is transformed into AC electricity. Additionally, inverters might include transformers that adjust the voltage of DC and AC currents.
Electricity circulates throughout your home, supplying power to various equipment.
Solar inverters distribute the converted alternating current energy to your home’s electrical panel. From there, electricity is distributed throughout your home to all of your outlets, ensuring that when your devices require charging, there is an adequate supply of usable electric current.
Solar panels generate excess electricity that is fed into the grid.
With a grid-connected solar system, electricity may flow both to and from the power grid, and excess energy generated by your panels can actually earn you money. You obtain credits from the power grid when you give electricity back to it under a scheme known as net metering, which reduces your overall cost of electricity even further.
Solar panel advantages
Now that you understand what they are and how they work, we can explain why you should care.
- Solar energy is a renewable energy source that will be available for as long as the sun exists, which experts estimate will be at least five billion years.
- Reduces power bills: Because solar panels will provide a portion of your energy needs, your total electricity bills will decrease. Additionally, you can earn money by selling any excess electricity back to the grid.
- Household energy consumption requirements are often higher in the afternoons and nights when people are at home.
- Solar panels are low maintenance — they just require cleaning a few times a year. Warranties are typically 20-25 years, and the inverter needs replacement after ten years.
The future of solar
To outpace current solar cells, a new design would need to capture more light, transform light energy to electricity more efficiently, and/or be less expensive to build than current designs. Any improvement to current solar cell designs must bring down overall costs to become widely used.
