A Guide to Solar Energy System

Are you ready to discover a secret that could drastically reduce your electricity bills by up to 75% or more? Switching to a solar energy system can drastically reduce your electricity bills and potentially free you from rising electricity bills.

Not only this, you can even sell electricity to the national grid and earn some extra income. Just imagine instead of paying your bills, you are earning from selling electricity. It’s not a dream; it’s the power of solar energy.

This article unveils the key to your energy independence – a comprehensive guide to solar energy systems.

Let’s dive into it.

What is solar energy systems?

Solar energy systems is a technology that converts solar energy into electrical energy that you can use to light up your house and businesses. It is a renewable source of energy, which means that it is abundantly available in the world and is environmentally friendly. Solar panels or photovoltaic cells are used to harness solar energy. You can get these panels from any solar energy system supplier in the market.

How do solar panels work?

Solar panels are the powerhouse of solar energy systems. It is the heart of the whole solar energy system. It converts the solar energy into electrical energy through a principle called photovoltaic effect. 

Solar panels are made of photovoltaic cells, which are grouped into modules or arrays. These cells are made of special materials called semiconductors, mostly silicon. When the sun’s rays strike on these panels, they excite the electrons in the outermost shell of the silicon semiconductor, and this freed electron produces an electric current. You have electricity.

The electricity produced by these panels is direct current (D.C.), and you need to convert it into alternating current (A.C.) through an inverter to power up your house or business. Almost every solar energy system supplier has all these equipment.

Types of solar panels

Solar panels is a relatively new technology and is still evolving. The typical types of solar panels supplied by solar energy system providers can be classified into three primary categories—monocrystalline, polycrystalline, and thin-film solar panels. Each of them has their pros and cons.

Monocrystalline: These panels are made up of a single silicon structure and a sleek black appearance. Usually, solar energy systems suppliers recommend this technology as they are efficient and durable. Its efficiency is around 25%. It means that it converts the 25% of sun energy that strikes its surface into electrical energy.

Polycrystalline: These solar panels are made up of multiple silicon crystal structures. They are bluish in color and have more and have a more distinct, textured look. These are less efficient and less expensive than monocrystalline. Its efficiency is around 17%. If you are tight on budget, then ask your solar energy system supplier for polycrystalline panels.

Thin-Film: They are made by applying thin layers of semiconductors on a substrate such as glass, plastic, or metal sheets. The commonly used thin-film materials are amorphous silicon (a-Si), copper indium gallium selenide (CIGS), or cadmium telluride (CdTe). They are more flexible and have versatile applications. Its efficiency is around 10%.

AllTop Group is a reliable solar energy system supplier, and you can rely on them for all your solar energy system needs.  


Benefits of solar energy systems

Now that you know the technology, let’s discuss why you should go solar.

Economic benefits: By installing solar panels, you can drastically reduce your electricity bills. In some cases, you can sell extra energy back to the grid and earn some extra income. Government incentives and tax credits also provide financial incentives for solar adoption.

Environmentally friendly: Solar energy is a sustainable and renewable source of energy. Traditional energy is produced by burning fossil fuels, which produces carbon dioxide that causes global warming. Hence, shifting to solar energy can reduce global warming.

Energy independence: It gives you energy independence. You don’t rely on grid electricity to light up your house or business. You become indifferent to power outages and price fluctuations.

How many solar panels are required to meet your needs?

That depends on your energy needs. You can simply calculate your total energy need and install a solar energy system that has 30% more energy production capacity than you need. Solar panels are rated in watts. So, if you need 4KW of energy, then you need to install 20 solar panels of 200W each.

You can calculate your total energy demand by simply adding the watt power of all the appliances in your house or you can request your solar energy system supplier to do that for you. On average, it takes about 1.214 KW to power a home in the U.S.

How much does it cost to install solar panels?

Solar energy system costs vary depending on the type of solar panels, design, energy requirements, climate, quality of equipment, location, the size of the system, and government incentives. On average, a solar system can cost between USD 2-3 per watt. This means a 1.2 KW system will cost you USD 2,500-3000. You can even discuss it with your solar energy system supplier. But remember, this is a one-time investment. This will provide you free electricity for the next twenty years.

How to install solar panels?

The installation of solar panels requires great knowledge, skills, and experience. So, you can hire a solar system installation company to install solar panels for you.


In conclusion, shifting toward solar energy systems is a reliable way to get energy independence and reduce carbon emissions. It is a clean, reliable, and cost-effective way to power our homes and businesses while reducing our environmental impact. So, let’s go solar and save the planet Earth.
