The cost of solar panels is less than ever before and they also represent a better value for homeowners. They can typically produce far more power than older panels and will last years longer on a typical home as well. Choosing the right solar panel for your home can save you money and will help produce the power you need.
The most important/expensive part of most modern home solar power systems is the solar panel itself; thus the solar panels price drives the cost of the system. This single component handles the conversion of sunlight to power and choosing the right model for your home can have a huge impact on your systems efficiency. These panels have become less expensive and more efficient in recent years and offer a much better value over the long term than ever before.
Understanding the differences between panels can help you also understand the reason for a particular solar panels price. Even though most models of panels for homes are less expensive than ever before since majority are China solar panels, trying to balance the cost of solar panels with their efficiency will help you make the right decision.
Standard Sizes, Varying Output Voltages
Modern panels are available in a standard physical size and are typically offered at several different output voltages. Normally the higher voltage panels allow you to harvest more of the power they produce because they suffer less losses in the conversion process. This is a good thing to keep in mind when shopping for a home solar power system since it can allow you to generate more power for your home from a given panel.
Output Power’s Importance
The other factor you need to consider is the output power a given panel can produce. Because these modern solar panels are much more efficient in their conversion of sunlight to power, they can typically produce far more power than older models from a given amount of sunlight. In some cases this can be several times more power than panels sold even a few years ago were able to provide. This is important because even though the cost of solar panels that are more efficient may be higher, you will need less of them to produce the power your home requires and the overall system price will be less as a result.
The smaller the number of panels means less roof space is required for mounting as well as a simpler installation overall. All of this leads to reductions in cost for your home solar power system. Bear in mind that when comparing the various choices for solar panels for your home since your first thought might be to choose the least expensive panel available; in the long run choosing a more efficient solar panel would be a better decision, even if it costs a little more initially.
Check the Warranty
Another consideration that affects the cost of solar panels is their warranty. Most modern solar modules are guaranteed for 10 years or more against defects and failure. Even though this may seem like a good warranty, most panels don’t fail completely. Failure in a solar panel typically happens gradually over time and will slowly lower the output power that the panels produce for the home. This slow decay in their output power means that they haven’t actually failed, they’re just producing less power.
Some of the newer solar panels for homes provide a basic warranty that covers any failures to the panel itself as well as an additional warranty to ensure it continues to produce a given amount of power over its useful life. This type of double warranty is important since it will typically ensure the replacement of a panel that falls below a certain percentage of output power over time. Even though solar panels that offer this type of warranty may be more expensive than others without the warranty, this peace of mind can easily justify the solar panels price.
