How To Choose a Solar Panel - Buying Guide

When choosing a solar panel, it is important that you consider things such as cell type, dimension of the product, and the maximum power so that you can find one that meets your needs. 

Choose a Solar Panel Based on the Cell Type

Currently on the market, there are multiple cell types such as monocrystalline, polycrystalline, or amorphous. Each type has its own pros and cons that you should know in order to make the right decision. 

Monocrystalline: Highly Waterproof and Good Conversion Efficiency Level

Monocrystalline: Highly Waterproof and Good Conversion Efficiency Level
Monocrystalline panels have a high level of silicon purity, which means that a solar panel made from this material can convert energy more efficiently than other types. However, when taking into consideration the price factor, a monocrystalline solar panel tends to be the most expensive one.


A monocrystalline solar panel can work well in different environments. It's often waterproof and weather-resistant as well. If you live in an area with a varied climate, or if your energy demand is high, then choosing a solar panel made from monocrystalline may be a great choice

Polycrystalline: Affordable with Decent Energy Conversion Efficiency

Polycrystalline: Affordable with Decent Energy Conversion Efficiency
Polycrystalline is a common material for solar panels due to its affordable pricing and environmental-friendliness. Its energy conversion efficiency is also pretty decent.

However, in comparison to monocrystalline, polycrystalline does not work as well in hot, humid weather conditions. If you live in an area with an average temperature of over 80 degrees Fahrenheit, you should opt for other options. 

Amorphous: Small Size and Suitable for Small Households

Amorphous: Small Size and Suitable for Small Households

Amorphous cells--also called thin-film cells--are small and compact, thus suitable for small households. Its price is also affordable, around the same as that of polycrystalline type. 


To achieve high energy conversion efficiency, they're "stacked" with multiple layers of amorphous cells on top of each other. This makes them more energy-efficient. If you want to concentrate or customize your solar power into one space, then this may be a good choice for you.

Flexible Panel: Versatile and Lightweight

Flexible Panel: Versatile and Lightweight

Flexible panels consist of silicon cells that are ultra-thin and tiny. Monocrystalline and polycrystalline can be used to make flexible panels as well, but since they are made from silicon wafers that are a bit thicker than human hair, they need to be cut down in size in order to become thinner. 


The advantage of flexible cells is their versatility. If your roof is not strong enough to handle tons of solar panels or is rather curvy, then flexible panels--which are lightweight and can be used on various surfaces--can come to the rescue.


However, the conversion efficiency rate of flexible solar cells is around 16 to 20%, so they are not as efficient as traditional ones. Therefore, flexible cells should be used for small projects that don't require a lot of energy. 

Pick a Good Frame and Glass Quality

Pick a Good Frame and Glass Quality
When choosing a solar panel, you should consider the quality of frame and glass as well, since they play an important role in protecting the solar cells. You should choose solar panels that are protected by aluminum frames. They are firm and can withstand a lot of pressure. On top of that, they are thick, rust-resistant, and durable.

Aside from the frames, the glass layer is also important. It helps prevent environmental pollutants and pressure from damaging the cells as well. You should choose a thick glass layer that is relatively strong and not easily broken or cracked

Choose a Solar Panel Based on the Size

Choose a Solar Panel Based on the Size
Since it is important to ensure that the system can power all your appliances, you should look into the solar panel's maximum power and voltage. If you just want to charge a cell phone, you don't need to spend money on something meant to power an RV.

However, even though the maximum capacity may be 100 watts, there's no guarantee that you'll actually get 100 watts in an hour. The generated power depends a lot on environmental conditions (shady or bright) and direction of the panels, so typically the generated power will be less than the indicated maximum power.


Size is also another factor to consider, as you need to have enough space to install the panels. Typically, the dimension of the panel corresponds with its power capacity. Panels that can generate more power tend to be larger than those with less capacity.

Find a Solar Panel That Matches Your Purposes

Find a Solar Panel That Matches Your Purposes
Nowadays, solar panels are created in many forms, either compact or rigid, to serve multiple purposes. If you want to bring solar panels camping or or on some faraway trips, you should choose foldable solar panels, as they are lightweight and can be folded into a much smaller size suitable for traveling.

However, if you just want to use solar panels at home and do not need to bring them anywhere else, you can buy the traditional type that is more rigid but offers more security. But nowadays, even some rigid and traditional solar panels are designed in a way that can be used for your RV, yacht, or campsite.

How to Determine the Amount of Solar Panels You Need

To determine how many solar panels would be sufficient to power your house's appliances, you should consider how much energy your household utilizes, where you would put the panels (roof, lawn for example), and how much usable surface area is available. 

Calculuate Your Current Electricity Output

Calculuate Your Current Electricity Output
To figure the required electricity output, you should look at the section indicating your average usage (kilowatt hours used or kWh) in your past utility bills. If you want to power your household with 100% solar power, then you need to purchase solar panels that can generate more than your average daily usage.

To find out how many solar panels you probably need, you can multiply your required hourly energy by the peak sunlight hours in your region and divide that by a panel's wattage. There are also some online websites that help you calculate how many solar panels you need, including Gogreensolar or Wholesalelsolar

Decide Where You're Going to Put the Panels

Decide Where You're Going to Put the Panels

To get the most solar power possible, you should place the panels where they can get the most sunlight. Typically, rooftops and lawns are the ideal places. You should also calculate the usable spaces as well. 


If you need to install a lot of solar panels but your rooftop cannot really accommodate all of them, then you probably need to figure out another placement such as on the lawn.

Reduce Your Carbon Footprint Even More with These Products!

Here are some more products that can help you live comfortably while protecting the environment, too.

Summary

Since solar power systems are becoming more and more common, many solar panel products are being created to suit different needs and purposes. 


For those who are not really familiar with solar panels, you may feel lost with all of the available options on the market. Hopefully, with our buying guide and list of the top 10 best solar panels, you can find a good product for yourself!
