Cadmium Telluride Solar Cell
The cadmium telluride solar cell is another interesting piece of solar technology that you will want to be aware of. This is something that is already being used in certain places, but it has not yet become widespread. There are several good things about this solar cell and also some negative things. The most important positive aspect of this solar cell is that it is very inexpensive to produce.
Making this solar cell is pretty easy overall. It uses cadmium telluride to create a solar cell that is very efficient overall. You donât even have to use very much water in order to make this type of solar cell, which is quite convenient. There is a low energy cost to make these solar cells and the production time is very reasonable too. This makes it a desirable option for those who wish to save money while cutting back on their use of traditional fuel sources.
This is a technology that could potentially help to lower the carbon footprint of citizens and even large businesses. You might be wondering why it isnât in regular use currently due to all of the positive qualities that it has. Simply put, cadmium telluride is toxic when it is breathed in and when it is ingested. This makes it somewhat dangerous to make use of these solar cells and it has put people off from fully committing to the technology.
How Much Solar Power Do You Need
The amount of solar power needed for your home depends on your average electricity consumption measured in kWh . For the average-sized home, this usually comes out to about 900 kWh a month.
Obviously, this number can go up or down depending on a number of factors, but this amount of energy usage translates to about 28-34 solar panels. Geographic location, access to sunlight, home size, panel efficiency, and wattage output will all play a part in the final outcome.
The Best Solar Panels For Home Use

Assess Your Options For Using Solar
Purchasing and installing a system that you fully own and maintain is no longer the only option if you want to go solar. Even if you rent your home or don’t want to purchase a rooftop system, there are many programs will enable you to still benefit from solar electricity.
Below are some of the options available for using solar energy at home check with local installers and your utility for programs available in your area.
Purchasing a Solar Energy System
Purchasing a solar energy system with cash or a loan is the best option when you want to maximize the financial benefits of installing solar panels, take advantage of tax credits, and increase the market value of your home, and a solarize program is unavailable or impractical.
The solar installer will connect the system to the grid, and receive an interconnection permit from the utility. When the PV system generates more power than the homeowner requires, the customer is often able to sell excess electricity to the grid, and when the homeowners electricity needs exceeds the capacity of the system, the home draws energy from the grid as usual.

What Are The Different Types Of Solar Panels
When shopping for residential solar panels, it’s also helpful to know the basic types that are available. The three basic categories are monocrystalline, polycrystalline and thin-film. Each type of solar panel comes with its own list of pros and cons.
Monocrystalline: Monocrystalline panels are made from a single, pure crystal of silicon. This allows them to have higher efficiency levels, but they also tend to be more expensive due to a more costly manufacturing process. Note: If you have less space on your roof and can only fit a small number of panels, monocrystalline solar panels may be the only viable option.
Polycrystalline: Polycrystalline solar panels are also made of silicon, but in this case, they are assembled from smaller fragments. This means they are often a little less efficient than monocrystalline panels, but they are also a more affordable option.
Thin-Film: Finally, thin-film solar panels can be made from a variety of ultra-thin materials. Thin-film panels are recommended when you need something that’s lightweight, flexible and portable they may work better for RVs and campsites than for homes. Thin-film panels can be relatively low in efficiency when compared to the other two options.
Listen To Your Installer
Youre probably tired of hearing this, but if you truly want to get the most out of your panels you should listen to your installer. You may think you have the perfect spot for your solar system, but there are a lot of details you may not have considered. The best way to place and angle your panels will differ depending on where you live. The pros will know just how to place the panels to ensure that they function at peak efficiency.

Is It Worth Buying Cheap Solar Panels
Solar panels can indeed be expensive, and some will want to find the cheapest solution. Cheap solar panels can make the setup costs more affordable, but they may not be worth it in the long run. After all, investing in solar energy is a decision with long-term implications. Cheap solar panels are likely to have a shorter lifespan and lower efficiency, and for that reason, your savings might be less significant.
When considering installing solar panels in your home, solar panel prices should not be the only factor. It will pay off, in the long run, to invest in high-quality panels and especially in a premium inverter from an MCS-certified installer that has a good reputation in your area.
Assess Your Solar Potential
Before deciding on the best way to use solar electricity at home, assess the potential solar energy that can be produced at your address. Because PV technologies use both direct and scattered sunlight to create electricity, the solar resource across the United States is ample for home solar electric systems.
However, the amount of power generated by a solar energy system at a particular site depends on how much of the sun’s energy reaches it, and the size of the system itself.
Several mapping services and tools are available to help you determine your homes solar energy potential. Some of the services also offer information on the estimated system size, potential costs and savings, and local contractors.
These tools are an excellent starting point and can help you determine whether your home is suitable for solar, and if not, the best path forward for still benefiting from solar. While these tools are helpful, they don’t account for all of the variables that need to be considered for your particular system. For that, you will need to work directly with a solar installer who can provide an accurate assessment of your solar potential as well as detailed recommendations, estimates, and equipment expertise.

Do Solar Panels Increase The Value Of Your Home
Solar panels can increase the value of your home as they make your house more energy-efficient. This is one of the home improvements that make your home more attractive to potential buyers, as the new owners can enjoy the same benefits of reduced electricity bills.
Naturally, the size of the solar panel system will affect just how much the value will increase, and bear in mind that different families will have different energy expenditure habits. That means that one system may be adequate for some families and inadequate for others.
For some buyers, solar panels are not a valuable addition to a home, so it does depend on personal preference.
What Solar Panel Cell Technology Is Best
In 2021, monocrystalline solar panels are best for home solar systems.
There are actually three types of technology utilized in the solar panels available on the market today. They are monocrystalline, polycrystalline, and thin film amorphous solar cells.
Monocrystalline solar panels are touted for their uniform, sleek look, whereas polycrystalline panels have a fragmented appearance and a blue hue. Thin film is the least efficient, but the least expensive.
Historically, the vast majority of solar panels on the market were either monocrystalline or polycrystalline, or ‘mono’ and ‘poly’ for short. Monocrystalline solar panels have always been preferred for their better performance and aesthetics, while polycrystalline solar panels attracted budget-conscious consumers due to their lower cost.
That has now changed. With recent improvements in technology, the price difference between them is now as little as $0.10 per watt, or less. As such, there is no longer a significant cost incentive to opt for poly panels. For that reason – barring the odd exception – the best solar panels currently on the market are all monocrystalline panels.
Without getting into too much detail, here’s what you need to know about these two types of solar panels:
