At the heart of any modern residential solar power system are the PV solar panels. These solar panels are the critical component in the system that does the actual conversion of sunlight to electricity. They do this by means of the use of solar cells that are designed to take advantage of the photovoltaic (PV) effect. The PV effect occurs in certain supplies, that when exposed to direct sunlight will generate a small DC current. In the case of modern solar panels for homes, these solar cells are made from a silicon-based compound that has improved dramatically over the years in efficiency. These modern solar cells are able to offer far far more power than older versions and are a lot more durable as well. In some cases these new solar panels for homes can deliver over twice as a lot power from the exact same quantity of sunlight as older panels because of these improved solar cells.
The fact that these new solar panels for homes are much more efficient than older versions is crucial for most homeowners for numerous reasons. It means that most home solar power systems will want less of these newer, high efficiency solar panels to generate the same amount of power as an older and bigger system required in the past. This can save you both roof space and the expense of all the extra panels you would have needed for an older system. It can also support lower the installation cost and complexity since there are much less solar panels to mount and wire into the system. All of this helps to make these modern solar panels for homes a a lot greater value for customers.
In addition to higher solar panel efficiency, there have also been improvements and innovations to the inverters that take the DC output from these solar panels and convert it into AC power that can be employed by the house. Modern versions of these inverters are much far more efficient and are able to convert a bigger portion of the power they receive from the solar panels into useful solar power for homes. Because you are wasting less of this solar power to the conversion method with these new inverters, you require even fewer panels than older systems required.
An additional emerging trend among some solar panel vendors is to truly contain a mico-inverter built into the solar panel itself, and do the conversion of power at the panel. This helps to enhance solar panel efficiency even further by eliminating the power loss associated with long cable runs between the solar panels and a standard inverter that is typically located near the power panel of the home. This power loss could account for as a lot as 15% or more of the total system power in older systems and was an high-priced dilemma for several homeowners that can be eliminated with these newer solar panels for homes.
Another benefit that these newer solar panels provide is their durability. Older panels could normally last 10 years or much more on a property but would commence to generate less power each year as their solar cells decayed. This meant that even though these older panels had been still generating power, they would degrade to the point that they necessary to be replaced far sooner than expected. Most newer panels can not only last longer than older panels, they are also able to generate their peak output for most of their lives and not suffer from the slow degradation like older panels. In truth many of the manufacturers will now warranty their panels for both guarantees against failure in general and guarantees against a degrading power output. This indicates you can have a panel replaced under warranty if it fails outright, or if it starts to generate considerably much less power over time. This gives you peace of mind that your investment will offer the power you need for decades to come.
