Choosing the proper solar panels for your home takes a little consideration and understanding the differences will help you decide between the varieties of options available to you. The good news is that no matter what style of solar panel you settle on, you are assured to have one of the most efficient and durable solar power solutions ever produced.
When you start shopping for solar panels, you need to understand that the panels are usually designed to supply a given voltage. The choices for panel voltages used to be limited to a few choices and most systems were either 12V or 24V systems. Because these solar panels have been dramatically improved over the years, modern panels have a wider choice of voltages and you need to be sure you don’t mix different voltages in your system. When selecting a solar panel, always try to buy one with the highest voltage you can afford as there will be less voltage loss and you will be able to convert and use more of the power your solar panels are providing.
You will also need to install an inverter as part of your system and it needs to be matched to the voltage you select for your solar panels. This inverter will be used to convert the DC current generated by the solar panels into AC current that can be used for your home and the inverter will expect a certain voltage to be supplied by your solar panels.
Another consideration when choosing your solar panels is their efficiency. Even though all of the modern solar panels are much more efficient than they were even a few years ago, some of them are better than others in their ability to convert sunlight to power. However, keep in mind that these more efficient models are also likely to be more expensive. If you can afford these more efficient models, they can make sense as you will need less of them to generate the same amount of power, and they can pay you back in free power very quickly to make up for their difference in price.
The final thing you need to consider is the way the solar panels mount to your roof. In older versions of solar panels they would simply attach to your roof with a few simple brackets. Even though this worked well it required you to puncture your roof with a lot of screws that were required for the various mounting brackets. Over time, each of these screws became a possible leak as the panels shifted over the years. Most of the modern systems use a rail assembly that requires fewer mounting points and eliminates a lot of the potential for causing a leak in your roof. These rails also make expanding the system easier in the future by allowing you to expand the rail and simply slide additional panels onto the rail system and secure them. This enables you to increase the power your system generates each year by simply adding more solar panels to your rails and connecting them to the inverter.
