What are solar panels made of, and how do they work?
Primarily, solar cells are made from silicon, which is a chemical element that has conductive tendencies. When silicon is exposed to light, its electrical characteristics changes, and this leads to the generation of an electric current.
What are the parts of a solar energy system?
Apart from the panels, you need an inverter to convert the energy into a format that can adequately power your appliances. Also, you need batteries to store the energy generated, and you can’t do without a charge controller, which controls the charging rate of the batteries.
● Solar panels
● Charge controller
What are the pros and cons of solar power?
Here are some of the pros of the solar power system:
● Renewable: Sunlight is an inexhaustible resource, meaning that you can use it over and over again. It is not like oil that can deplete with time.
● Lower Electric Bills: With an ideal solar power system in your home, your electricity bill will reduce every month. It can be a good source of replacement for properties tied to the grid.
● Remote power: If you live in a remote area with no access to the power grid, a solar system can help you out. Your property will be powered, and you won’t need to pay monthly bills.
● Improve Property Value: A home with a solar system will have more value than one without it. If your property is located in a rural area, you can boost its value by making it solar-compliant.
On the other hand, there are cons associated with the use of solar:
● High up-front cost: You should be prepared to spend much on an ideal system that will power your entire house. The up-front cost can be high, but you will offset in the long run.
● Weather Dependent: If your panels don’t get enough sun, they will not generate enough electricity. Snow, shade, and other obstacles can affect their optimum performance. However, there is the equipment that can prevent this, but you will need to pay extra to get it.
● Takes up space: Depending on the configuration of your system, solar panels can take up a lot of space on your property. The majority of them are over 3 feet in width and more than 7 feet in length.
Tips for choosing the right solar panel size:
You need to put your focus on the vital aspect of the deal instead of advertising because you will be spending a lot of money in the process. Recommendations from friends is not a bad idea, especially from those who have installed the system in their homes. They will be in the best position to inform you about what they have experienced with the system. If there are problems you need to avoid, they will be in the best place to tell you.
Besides, you should determine the type of panel you want to use. The two major solar panels types are monocrystalline and polycrystalline.
Monocrystalline panels are more expensive, but they are more efficient. If you don’t have enough space to accommodate so many panels, you should go for this type.
On the other, polycrystalline panels are cheaper but not as effective as monocrystalline panels. You can consider this type if you have enough space for many panels. Also, you should consider adding more panels in the near future during your planning process.
Also, you should stay away from salespeople that want to put pressure on you. You need to avoid making abrupt decisions so that you won’t end up making the wrong choice. You should take your time without being rushed into making a decision. Remember that you are making a decision that will impact your life for a long time. Hence, you should not rush into making decisions.
How long do solar panels last?
Most panels will last for more than 25 years, with the least efficiency level standing at 80%. They don’t break down even when the manufacturer’s warranty expires. However, other components of the system, like batteries and inverters, have a shorter lifetime. Expectedly, you may need to replace them at least once in the lifetime of your system.
A lead-acid battery has a lifespan of between three and seven years, and this is dependent on how well you maintain it. Lithium batteries can last for between ten and fifteen years. For inverters, their lifespan can be between ten and twenty years, and your maintenance culture will determine how far they can go.
Multiple things to consider before selecting the right solar panel size
Solar panel dimensions vary, but before you can decide on this vital issue, you need to put so many things into consideration. Some of them are discussed below.
● Your budget: The first thing to consider is your budget. You need to be clear on the amount you want to spend on the project. Also, you can find various financing options so that setting up your system will be a piece of cake. Check with your local tax authority if you are eligible for a tax credit. Also, you can go for a lease agreement, which will undoubtedly reduce the upfront cost of obtaining the system.
● Available roof space: The size of your roof space will determine the solar panel size you will go for. You should make sure that you get the exact measurement of your roof, and you should use this measurement to choose the perfect panel size for your home. Also, you should place the panel in such a way that it will get direct rays from the sun. Ideally, the panels should be placed 90° to the sun.
● Electricity use or need: You need to investigate your energy use. You should know your total electricity usage, and you may need to work on reducing your electricity use. If you are connected to the grid, you can use your electricity bill to measure your usage. It will be shown in kilowatt-hours (kWh), and you can review it on a monthly basis.
● Future energy plans: Your future energy plans will also determine the panel size to go for. If you are planning to get more electric gadgets in the future, you need to put this into your plan before making a purchase.

Solar System Size: How to Calculate Yours?
To get the actual number of solar panels that will power your house, the first thing you need to do is calculate the hourly energy requirement of your home. Then, multiply the hourly energy requirement with the number of hours you have peak sunlight in your area. Then, divide the result by the wattage of the panel. You can use a low-wattage (150W) and high-wattage (300W) values to get a range of estimated outputs.
If the measurement of an average solar panel stands at 65 inches by 39 inches, how can this translate to a full-sized rooftop solar panel system?
Since the average system in the United States is 6 kilowatts (kW), and you install a 6kW solar system making use of about 20 average-sized panels. You will probably get a system that measures approximately 27 feet by 13 feet. This will give you an area of 352 square feet, provided that the panels are placed close together with no obstacle on your roof.
How much do solar panels weigh?
You need to know the weight of solar panels when planning a solar system. Understanding the importance will help you to be sure that your roof can support a full installation. The majority of solar panels, especially 60-cell residential panels, weigh about 40 pounds, but there are variations from one brand to another. Some brands can be as light as 33 pounds, and some brands can weigh as much as 50 pounds.
Solar panel weight by the manufacturer (60-cell Residential Panels)
|SolarWorld||40 – 47 lbs|
|Canadian Solar||40 – 51 lbs|
|Hyundai||38 – 41 lbs|
|Hanwha SolarOne||40 – 42 lbs|
|Hanwha Q CELLS||41 lbs|
|Trina 41 – 50 lbs||Trina 41 – 50 lbs|
|SunPower||33 – 41 lbs|
|Axitec||39 – 41 lbs|
|Kyocera||42 – 44 lbs|
Is it possible for your roof support to support a solar panel system?
If you know the size and weight of solar panels, it will be easier for you to calculate the capacity of your roof to support a solar panel system. For an installation targeting 6-kilowatt output, you will use about 20 solar panels. Ideally, each panel will weigh about 40 pounds, meaning that the total weight will be about 800 pounds.
Also, this system will measure 352 square feet, and this means that the weight per square foot is 2.3 pounds (800 pounds ÷ 352 sq ft). When you consider other installation materials, like mounting hardware, you will get a total weight of around 4 pounds per square foot.
Roofs on the majority of newer homes have the capacity of withstanding the weight of more than 3 pounds per square foot. If your home is of the old type, or you are not sure that it can support the weight of solar panels, you can have a chat with your roofing company. A simple roof inspection is all you need so that you can be sure that putting the burden of solar panels on your roof will not be disastrous.
