Residential solar panels have become an incredibly popular way for many homeowners to reduce their monthly expenses by generating free electricity from simple sunlight. Using the sun to provide the electricity they need for their home each day allows them to lower the amount of energy they need to purchase from their local utility. These residential solar power systems can save the average home a substantial amount of money each year and will help the environment as well. The key to these savings is finding the right residential solar panels for your home and understanding the part they play in the overall system.
All residential solar power systems are basically comprised of three main components that together generate free electricity. These systems typically include a set of solar panels, an inverter and a controller. These individual parts all have different functions and work together to collect, convert and deliver clean consistent power to your home.
At the heart of any solar power system is the residential solar panel itself. They are the physical part of the system starts the process of converting the free sunlight arriving at your home each day into power that you can use to run your appliances and lighting. Because they play such an important role in your system, you need to clearly understand the differences between them when buying solar panels for your home to make sure you get the best value for your money.
There are basically two main types of solar panels in use today that are either based on a monocrystalline and polycrystalline design for the solar cells at their core. Both of these are based on a silicon crystal that has the ability to convert any sunlight that strikes it into a small DC current. The monocrystalline is made from a single large crystal, which is difficult to grow. This unified crystal adds to the cost of this type of solar panel but also allows it to produce more power from a given amount of sunlight than the polycrystalline version because of its higher purity. Most residential solar power systems use solar panels that are based on the monocrystalline solar cell, which has gotten more efficient every year as their formulations improve. The polycrystalline design is similar to the monocrystalline but instead of a single crystal it is made from a collection of smaller crystals that are connected together to work in tandem. This type of solar cell is less expensive to manufacturer but will also deliver less power on your home.
Both types of solar panels have their advantages and deciding between them is normally based on your budget and power needs. If you have a smaller home or tighter budget, the polycrystalline solar panels will work well for you and can allow you to install a residential solar power system on your home that is very reasonably priced. If you have a home with larger energy needs or you are trying to eliminate your power bills completely you might want to consider the more efficient monocrystalline solar panels for your residential solar power system.
