Solar power for home use has become more popular in recent years due to increased affordability. Growing environmental consciousness is also playing a role in driving up the sales and popularity of home solar systems.
You may have heard about the advantages of using solar power that promises significant savings on electricity bills. Why is it then that we are not seeing large quantities of home owners rushing to utilize this wonderful technology in their homes?
We will thus discuss some aspects of using solar power within a home environment and explore its pros and cons. This article is just a general introduction to solar power and does not include specific details about using solar power in a particular country.
Nonetheless, I still hope it will help you gain more knowledge about solar power, one of the more popular forms of renewable energy that has been gaining traction in recent years.
How Solar Power Works
Using solar power primarily involves the installation of photovoltaic (PV) panels on rooftops of houses. The PV panels generate electricity, which can then be used to power home appliances and other electrical devices.
Solar panels are composed of many solar cells made from semiconductor materials, typically silicon. An electric current is created when sunlight hits these cells, which excites the electrons. This direct current (DC) is then converted into alternating current (AC) with an inverter, making it suitable for household use.
In recent years, solar technology has improved in efficiency. It can be generalized that modern solar panels are now about 60 percent cheaper and 40 percent more efficient than the panels produced in 2010.
Before we proceed further, I’d recommend to watch this educational video by TED-Ed. After watching the video till the end, you will understand why solar energy is not used widespread around the world even though Earth gets abundant sunlight,
Types of Solar Systems
You should know that there are broadly three main types of solar systems:
- On-Grid Systems: Connected to the utility grid, these systems can sell excess power back to the grid. You may receive credits or compensation from your electric utility provider as your excess electricity flows back into the utility grid.
- Off-Grid Systems: Operate independently of the grid and require battery storage to provide power during non-sunny periods. You would find this type of system very useful if your property is located in a remote area where electricity supply is not available or less reliable.
- Hybrid Systems: These systems enjoy the features of a combination of on-grid and off-grid systems. They utilize batteries for storage while also being connected to the grid. With this type of system, you can use solar power during the day and switch to grid power when solar energy is insufficient. During periods of blackout, you can also rely on hybrid systems to provide electricity in your house via the batteries.
Advantages of Solar Power
Solar Power Environmental Impact
Solar power is a clean, renewable energy source that significantly reduces carbon footprints. Its power is abundant and sustainable as long as the sun shines.
Reduced Energy Bills With Solar Power
You can significantly reduce your monthly electricity bills by generating your own electricity. A solar power system is especially effective in areas with abundant sunlight and where electricity bills are high.
Energy Independence With Solar Power
Solar power would make your life easier if your housing area is prone to electricity failures. Paired with battery storage, it is possible for a home to still function as normal in the event of a typical power disruption. Solar power is also particularly useful if you have a smart security system that you need to keep running 24/7.
Long Term Investment in Solar Power
While the upfront installation cost can be high, solar systems can give you a good return on investment over a lifespan of 10 to 20 years. Good quality solar panels also generally require little maintenance except for periodic cleaning and inspection.
Government Solar Power Incentives
City councils in progressive countries may offer financial incentives such as tax credits, rebates, and grants to offset installation costs. These incentives help make solar systems more affordable to home owners.
Better Home Value with Solar Power
Homes with solar power installations can attract higher resale values. Modern smart homes equipped with sustainable modern technology will appeal to buyers and tenants who are conscious about high electricity bills and environmental issues.
Tech Tip: Protect your online privacy.
Online data privacy is such a hot tech topic these days. Start protecting your online privacy by using a reliable virtual private network (VPN) service.
