Many of us have heard a lot about solar panels and how they use and promote clean energy. But how true is this, and do we have all the facts about solar power?
Relying on fossil fuels isn’t always possible, of course, but the alternatives being touted today may not be the best for you. Let’s see if solar energy is really the right choice for you.
A. How much do you pay for electricity now?
If you are one of those residents who simply pay their bills, you know how utility costs rise and fall each season. Green energy is gaining popularity every day, but does that mean it’s time to take action?
The first thing to consider is where you live and how the weather will affect the solar panels you need. Since you already know how these panels work, is there a lot of constant sunlight in your state?
The biggest problem with solar power is the amount of exposure it gets per day. This is ideal if you live in a drier desert climate. Cloudy or unpredictable weather will immediately reduce solar collection by half or more.
It’s also not so good if your roof is completely covered with panels. And when fall and winter come, how much sun is there? Is it worth the daily commitment to you and your family?
B. How much does it cost to install a typical panel system?
This is a question that many people have trouble understanding about solar panel systems. Not all solar panels are the same, and many give different percentages of solar panel efficiency. In general, solar panels at best achieve 22% efficiency when capturing sunlight.
The best of these can achieve returns of 26.7%, but these panel systems are quite expensive. If you decide to use solar energy, you should look for a specialized company.
You can expect to save money by hiring your own installer instead of using a company that sells panel systems.
C. Not all panels are the same.
The reason lies in the types of solar panels available in the market. Here’s why:
1. Mono-SL photovoltaic cells
This is the best panel you can get, with up to 22% growth, but up to 26.7% depending on the manufacturer. They are often smaller than the others, which makes it easier to cover the roof.
These panels are very effective where there is a lot of sunlight. The downside is that they don’t work at all when covered in snow or dust. They have to be cleaned again and again.
2. Polycrystalline solar module (mc-SI)
This is the next level of reduction, which can achieve an efficiency of 13-16%, and is therefore cheaper. This type of panel is best suited for areas that are not deserted and not hot, because the sun will burn the material over time.
To achieve the same performance as the mono-SL, twice as many modules are needed to recover the same amount of power.
3. Amorphous thin plates (a-SI)
This panel is the worst for energy harvesting and only offers a 6-8% return. These panels are more expensive because thin amorphous sheets are inserted into the panels.
The lifespan is less and the warranty is not as good, making these panels the worst choice you can make.
D. Are they worth it?
A good reason why it’s worth buying solar panels that your state already offers. This is the so-called solar energy tax credit, which is still being proposed in a bill that was saved by President Trump.
Through 2022, this tax credit is currently 26% for solar installations in the United States. Previously, in early 2021, it was 30%. This is still a significant savings, as you get back 26% of your initial cost.
As long as you choose a plan that gives you a 15 to 20 year warranty on your solar panels. This way you can be sure to save money on your electricity consumption for at least two decades.
The installation costs depend on the type of solar panels you invest in. Therefore, always choose based on the climate and weather conditions. As solar technology advances, efficiency is likely to increase.
frequently asked questions
Do you really save money with solar panels?
On average, installing a solar system costs about $13,142. … In addition to the federal tax credit, solar panels increase property values and reduce electricity bills. Compared to heating with gas or electricity, solar collectors save much more in the long run. Your solar panel system can pay for itself in three years!
Should I install solar panels?
So yes, solar power is worth it! Solar energy is directed to the house as it is produced. So when you use solar energy, you are not buying electricity from the grid. … With the solar panels now available, you can reduce your energy bills even further and power your home almost entirely with solar energy.
What are the 2 biggest disadvantages of solar energy?
