Solar technology harnesses the sun''s energy to generate electricity. It''s a form of clean energy that powers your home through solar panels on your roof. But what are solar panels and how do solar panels work? In this article, we''ll explain how solar panels power a home, the different panel types, and the benefits and drawbacks of solar.
Solar power companies can install different system types according to how dependent a homeowner wants to be on a utility company. Homeowners can choose the type of solar power system or solar array they would prefer based on their budget and needs. These systems include:
There are four solar panel types on the market. The type of panel you choose depends on your budget, location, available space, and energy needs. Different solar panels also come in various shapes and sizes. Below is an overview of the options available:
Monocrystalline panels are also called single-crystal panels because they are made from a single, pure silicon crystal that''s split into different wafers. They''re the most popular panels because of their efficiency, longevity, and aesthetic.
Monocrystalline panels have the longest life span of all four panel types, lasting about 25 years, and their efficiency rates are between 15% and 24%. They also offer a sleek design in black. These panels are the most expensive out of all four panel types because they use a lot of silicon, but their electricity output offsets the price tag.
Polycrystalline solar panels are composed of silicon fragments, which makes them easier to build. A manufacturer melts the silicon fragments and pours them into molds, where they solidify. Although they''re less efficient than monocrystalline panels, with an efficiency rate between 13% and 16%, they''re more affordable. You can also install more of them if you have enough space, which makes up for their lower efficiency.
Polycrystalline panels aren’t recommended for homes in hot climates, as both efficiency and panel lifespan decrease in high temperatures. They''re also more noticeable on a rooftop because of their bright blue color.
PERC panels are a newer panel type. They''re similar to monocrystalline and polycrystalline panels, but they have an extra layer underneath the cells. This additional layer is reflective and can send the light that passes through the panel back into the cell, creating more energy. That same reflective surface also prevents longer wavelengths from otherwise damaging the panel''s performance.
Thin-film solar panels are made of thin layers of different semiconductor materials. These panels use fewer materials than traditional silicon panels, but they''re also less efficient. At the same time, they are more affordable than traditional panels because they''re lightweight and flexible.
Conventional methods to generate electricity use fossil fuels to create heat and steam. The steam this creates powers a turbine, which produces electricity. The use of fossil fuels accounts for 75% of greenhouse gas emissions, a leading factor of climate change.
To reduce the dependency on fossil fuels to produce energy, CSP systems use mirrors to reflect sunlight onto a receiver filled with water. The sunlight heats the water, which powers the turbine and generates electricity with solar energy.
CSP systems are different from photovoltaic (PV) panels, which convert thermal energy into electricity. While CSP technology uses the sun''s energy to power a system, PV panels convert sunlight directly to electricity. CSP can power large-scale systems, such as power plants, but you wouldn''t use it to power individual homes like you would with PV panels.
When homeowners invest in solar panels, they reap many benefits, but they also encounter some limitations. In this section, we''ll cover solar panel advantages and downsides, providing you with a comparison to help you decide whether this electrical power system is right for you.
The cost of solar panels depends on your home''s size, panel type, and a few other factors, but on average, homeowners spend $31,460 for a 11-kilowatt (kW) residential solar panel system, or $22,022 after applying the federal solar tax credit. Solar panel installations of this size can cost between $25,960 to $36,960 before applying the federal solar tax credit.
