In the last decades, solar energy has grown to become one of the biggest and most effective kinds of renewable energy. Solar panels harvest the natural power of the sun to create electricity.
Solar panels also called PV panels, trap light energy from the sun. This light contains particles of energy called photons. The solar panels are able to convert these photons into electricity that you can use to power electrical loads, giving you a greener alternative to other forms of power.
If you are thinking of installing solar panels in your home or office you have come to the right place.
Stay with me as I take you through the various types of solar panels in the market today. I also show you how to install solar panels step by step to give you an idea of how the installation process looks like.
Types of Solar Panels
Solar panels have come a long way since they were first introduced. They are now much more advanced making them more efficient. They also look prettier on the roof of your house compared to before.
The main types of solar panels available in the market today are:
1. Monocrystalline Solar Panel
This type is the oldest and most developed. They are cut from a single pure crystal of silicon and appear black due to the interaction between sunlight and pure silicon.
2. Polycrystalline Solar Panel
These solar panels are a newer development in the market. Fragments of silicon are melted together in a mold then cut into wafers. Sunlight reflects on its crystals giving it a blue color.
3. Thin-film Solar Panel

Unlike monocrystalline and polycrystalline solar panels, thin-film panels can be made from other materials such as cadmium telluride and copper indium gallium selenide, and are cheaper and more flexible.
How to Install Solar Panels Step by Step
In order for your solar panels to reach their peak efficiency rate, the installation process must be done correctly. Before the installation, an MCS-certified installer has to carry out an assessment of your roof looking at basic safety factors including how strong the roof is, before approving the installation.
Things to Consider before Installing Solar Panels
There are a number of important safety issues that you need to take into consideration before installing solar panels. This is because solar panels involve a conversation of several hundred volts of electricity from the sunlight. It, therefore, goes without saying that the whole process needs to be handled by a certified professional after obtaining all necessary permits and meeting specific electrical standards.
1. Your Power Needs

Your power needs in terms of consumption based on the appliances you have will play a major role in the number and type of solar panels that you will need to install. To establish your power load, you need to study your electricity bills as well as statements for at least a year. This will guide you to determine how much solar energy needs to be produced to meet your power consumption.
To determine your daily average use, sum up your annual usage in terms of kWh and divide by 12. This gives you the average monthly usage. Then divide that by 30 to arrive at your daily average use.
2. Solar Panel Efficiency
Solar panel efficiency refers to the rate at which the panels are able to convert sunlight into electricity. Go for panels that have higher efficiency as it would mean you will require a fewer number of panels. With a more efficient solar panel, you will have a higher output thus able to charge your solar batteries faster. In addition, it will enable you to still get power even when the sunlight is not very bright. Average panel efficiency ranges between 15% to 20%. 20% plus being top of the line.
3. Roof Suitability
When you are considering installing solar panels on your roof, it is vital to take into consideration whether your roof will be strong enough to support the solar panel system that you want. Check to see that the entire solar array can fit in the available space as well. Although solar panels can be placed on all rooftops, the most ideal are flat roofs. Ensure that your roof can allow at least 30 cm of space all around the solar panels.
4. Size of Solar Panels
The bigger the size of the solar panel system the more electricity generated. Once you have calculated your power needs, you will be able to know what size of solar panels will work best for you. Based on the available space on the roof, this also will determine what size of solar panels you can buy. You can use this solar panel sizing calculator to determine how many panels will be needed on your roof.
5. Maintenance
Ensure to go for a solar panel that is easy for you to operate and maintain. Good maintenance helps maximize the lifespan of your solar panel system. Have your panels regularly checked by a certified service provider. Apart from seeking maintenance assistance from the installer, you can as well take part in the process by removing branches and leaves from your solar panels, rinsing them with water using a garden hose pipe but avoid touching the panels.
6. Solar Panel Durability
The average lifespan of a quality solar panel is between 20 to 25 years. A durable panel saves you the hustle of doing replacements all the time. Go for a solar panel that has proven impressive durability against environmental conditions. Going through product reviews from consumers who have used the solar panel type before you, helps to guide you towards the right choice.
7. Location and Direction
Solar panels should be placed on a roof that faces the direction from which the sun rises for maximum exposure. Ensure that the roof does not have any shade from obstacles such as tall buildings and trees. These may interfere with the amount of sunlight that actually reaches your solar panels. For good output, your panels should be able to capture the maximum amount of sunlight. Therefore, expose your solar panels to the sunlight for as long as possible.
8. Warranty
Go for solar panels that come with a longer warranty period. Settle for panels with performance warranties as this is a promise by the manufacturer of above-average performance. With such a warranty, the panel will be deemed defective if it falls below the set level. Most manufacturers in the solar panel industry today put it at least 80% rated efficiency. Solar panels come with 25 to 30 years of performance warranty periods.
Installing Solar Panels in 7 Steps
Solar panels generate electricity for home and commercial use. Either way, these panels are usually installed on the rooftop so as to get the maximum possible sunlight to generate as much electricity from the system as possible.
The following are the 7 steps involved in the installation process:
Step-1: Mount Installation
Begin by fixing the mounts which will support the solar panels, depending on your requirement. There are different types of mounts, including roof-ground and flush mounts. They both work well to provide a base structure that gives good support. When fixing the mounts, consider the direction in which the panels will be installed. Ultimately, the panels should face the direction in which there is maximum sunlight. Slightly tilt the mounting structure at an angle between 18 to 36 degrees.
Step-2: Install the Panels
The next step entails fixing the solar panels with the mounting structure. Fix the panels by tightening the nuts and bolts firmly. Make sure the whole structure is sturdy.
Step-3: Wiring
The next step is to do the electrical wiring. Using junction connectors or a fuse combiner box, wire the solar modules together. Use insulated cables. This helps to avoid leakages that may lead to accidents. Connect the exterior wiring with the interior panels. This connection allows the flow of energy to a charger controller then to a battery bank for storage. This step in the installation process is crucial and thus should be carried out by a qualified professional so as to avert injury or damage to your solar system. During the wiring process, panels can be connected with each other in form of two types of series;
The series connection where the positive wire of one panel is connected to the negative wire of another module. The good thing with this type of wiring is that it increases the voltage match with your battery bank.
Another option of wiring is the parallel connection. Here you connect positive to positive and negative to negative. With it, the wiring voltage of each panel then remains the same.
Here is a detailed guide on how to wire solar panels.
Step-4: Connection of Solar Inverter
Next is for you to connect your system to a solar inverter using the parallel connection series. To produce electricity, connect the solar inverter to the solar battery and grid input.

Step-5: Connecting Solar Inverter and Solar Battery
Connect the positive terminal of the battery to the positive terminal of the inverter and the negative to negative. The battery is used to store electricity in an off-grid system.
Step-6: Connecting the Solar Inverter to the Grid
The next step is to connect the inverter to the grid. Using a normal plug, connect to your main power switch.
Step: 7: Start Solar Inverter
The last step is to carry out a test run to ensure that everything is working correctly. Once you have confirmed all is well, you can start the inverter switch. Put on the inverter switch on the main switch of your home and start reaping the benefits of installing solar panels.
