Only about1.8% of the energyused in the U.S. comes from solar panels. Despite that, there are2 million solar installationsacross the U.S.
What’s happening is even though we’re continuing to add solar panels to the grid, we’re also, as a nation, upping our energy consumption.
So even though only a small percent of our energy comes from solar, it’s still a popular option. But is it viable? How efficient is solar energy?
Let’s explore that.
太阳能电池板的工作怎么样?
Solar panels consist of many smaller cells called photovoltaic cells. When sunlight hits these cells, it breaks electrons off atoms, which creates energy.
So the effectiveness of your solar panels comes down to how well the electrons are broken away from the atoms.
通常，大多数太阳能电池板在此过程中的效率约为15％至20％。然而，已经发明了一些太阳能电池板是23％的效率。
Even still, these are market outliers, and you’re more likely to get something closer to the 15% to 20% range.
什么影响了面板效率？
There are a lot of factors that go into how efficient your solar panels are. The initial quality matters of course, but even after that, there are several things you can do to keep your solar panels at peak efficiency.
How Much Sun Is Available
If you live in a sunny area, solar panels are a great idea! But if your forecast involves more cloudy days than sun coverage, you need to do some more research.
But don’t give up hope! There are a lot of factors that go into an effective solar panel, and just so long as you can see it, that means it’s getting light, and it can make energy.
Temperature – but Not Like You’d Expect
If you live in a cold, sunny area, you’re in luck! This is the perfect environment to get the most out of your solar panels. Solar panels are more efficient in colder climates than they are in warmer ones.
On top of that, snow acts as a mirror, and it can reflect sunlight off the ground back onto your solar panels, so they get more sunlight than they do without snow.
位置到太阳
为了充分利用太阳能电池板，您需要确保它们正确定位。许多太阳能电池板都配有系统，这些系统将在整天内向最佳角度定位。

Will Weather Break Them Down?
Fortunately, no! Thanks to laws like the Consumer Protection Act, solar panel companies have to provide solar panels that do what they promise.
在各种情况下广泛测试太阳能电池板。这是为了确保共同的天气情况不会破坏它们。
These include things like snow, ice, wind, hail, UV radiation, heat cycling, humidity, and even chemical exposure. Your solar panels need to be able to withstand these elements before they can hit the market.
As a result, most solar panels come with pretty impressive warranties, because companies know they can last. Most solar panels come with two warranties, one for the equipment itself, and one to guarantee performance.
The performance warranty ensures your solar panels will still be 90% as productive in 10 years, and 80% as productive in 25 years. The equipment warranty guarantees the equipment is good for 10 to 12 years.
Is That Enough to Power My House?
It is 100% possible to power an entire house, even if your solar panels only convert 15% to 20% of all the sunlight that hits them into energy.
But there are some things you should consider. When you decide to invest in solar panels, you need to know your exact goals. Are you looking to just subsidize your current energy usage, or do you want to be 100% solar powered?
You’ll need to know how much energy you already use. You can usually find this number as a whole on your energy bill from your power company. That’ll give you a good idea of where to start.
But many people decide that if they want to be completely solar-powered they should cut down on their energy usage in the first place, and that’s a good idea.
To Get the Most, Go With the Pros
It is possible to do a DIY solar power installation. But it’s smarter to go with the pros. Their experience and professional advice will keep you safe. You’ll be able to get the best deals and the most application out of your new solar power system.
Solar panels today are cheaper and more efficient than ever before. On top of that, solar tax credits have recently been extended. You can get atax credit worth 26%如果您在2020年安装它，则为您的系统。但在2021年下降到仅22％，除非大会决定续订账单，否则否则不存在。
So if you’re looking to get solar, there is no better time than today.
How Efficient Is Solar Energy? Now You Know
So how efficient is solar energy? Only about 15% to 20%. But that’s enough to dramatically lower your energy bills – or help you become entirely self-sufficient.
On top of that, recent extensions to solar tax credits make today the optimal time to invest in solar energy.
另外，您知道，环境崩溃，因此您可能应该确保您的能量需求被覆盖。
