1. Advantages of solar energy

1.1 Using solar energy can dramatically reduce or even eliminate your electricity bill.

When the user installs solar panels, you can use solar energy into electricity to generate electricity, reducing the number of electricity purchased from the energy company, depending on the weather and climate of the place of residence, the monthly electricity bill can be reduced differently, but can be to a certain extent to reduce your household electricity expenses.

And considering that solar panels typically last between 25 and 35 years, the long-term savings on your home’s electricity costs will be at least a few decades, which in the average home is about $25,000 to $110,000.

1.2 Solar can increase your home’s value

For most homeowners, installing solar panels on their home can be the only way to generate electricity. In fact, installing solar panels on your home can increase the value of your home, statistically increasing the value of your home by about four percent. In the future, if you want to sell your home, you can sell it for a higher price because you have solar panels, or you can choose to recycle your solar panels when you sell your home and even make some money back. Similarly, if you are buying a new home, installing solar panels is one of the favorable investments you can make in your home.

1.3 Using solar energy can reduce your carbon footprint and emissions

First of all, we need to know that solar energy is a true renewable energy source, as opposed to fossil fuels, which take a long time to produce and require expensive labor and machinery, and can be converted directly from natural resources into electricity. Another factor that makes solar energy more attractive as a renewable energy source than other fossil fuels is that it does not produce carbon emissions or any other greenhouse gases, whereas the burning of fossil fuels is one of the biggest contributors to the huge amount of greenhouse gases produced worldwide every year. Furthermore, the use of solar energy avoids the environmental damage caused by the harvesting of fossil fuels and the huge amount of water consumed in the process of generating electricity.

It can be seen that the use of solar energy can contribute to the reduction of carbon footprints, carbon emissions, and environmental protection all over the world, and it also means that it contributes to the protection of wildlife, the preservation of the earth’s ecological diversity, and the preservation of the diversity of the earth’s environment, among other things.

1.4 Users can even make money from solar energy

In some states SRECs, Solar Renewable Energy Credits, are given to users who use a solar power system and produce a certain amount of electricity, which the user can choose to sell on the SREC market for cash. This makes installing solar panels not only a way to reduce your home electricity bill, but can even lead to some profit, and that return is effective in the long run.

1.5 Solar panels require little maintenance

Since solar panels have almost no movable parts, they can work properly as long as the surface is kept clean and in better condition. The most important thing to remember when purchasing solar panels is to choose a quality solar energy company to install your solar panels, which will save you most of the maintenance costs and hassle of damages over the next 25 years of use.

1.6 Solar energy has a wider application

Other clean energy sources such as wind and hydroelectric power require certain environmental factors, such as a large, unobstructed space, sufficient wind power, or a large amount of water. However, solar energy is a clean energy source that can be produced in almost any environment. Although the output efficiency of solar energy is lower on cloudy days or in winter, the scope of solar energy is much wider in comparison.

1.7 Solar technology will continue to be developed in the future

For most people, the deciding factor in whether to install solar panels is the conversion efficiency of solar energy and its current high price.

This year, for solar power technology, the scientific community continues to make new progress, especially in improving the energy conversion efficiency of solar panels and battery storage system efficiency. And the future of the solar industry technology will continue to progress, some high-tech technologies such as quantum physics and nanotechnology will be added to significantly improve the efficiency of solar panels, so that its power output increased one to three times.

1.8 Recycling of solar energy systems is relatively easy

The first thing we need to know about solar panels is that they consist of photovoltaic panels and specialized solar cells. Although most of the batteries used in solar panels are lithium-ion batteries, there are limited ways to properly recycle lithium-ion batteries. However, other raw materials for solar energy systems such as photovoltaic panels, glass, and aluminium metal frames are easier to recycle, which means that recycling solar energy system materials does not have a significant impact on the environment.

2. Disadvantages of solar energy

2.1 Solar panels are not suitable for all houses

First of all, roofs that face south and are tilted between 15 and 40 degrees are ideal for installing solar panels, but some flat roofs that face east or west are less suitable for installing solar panels, so try not to think about installing solar panels if you have a north-facing roof.

Secondly, some older homes have roofing materials such as slate or cedar shingles that can make the installation of solar panels difficult, and some roofs with skylights and other additions can make the installation of solar panels more costly.

2.2 Higher Upfront Costs of Applying Solar Energy

Although the cost of installing a complete solar system including solar panels, inverters, batteries, installation, and other spare parts has come down after decades of industry growth and expansion, everything still requires a significant upfront investment cost. The average cost of installing a solar system is roughly $20,000 per home, if not more. And once a solar system is installed for your home, this means you’ll need to continue living in it for decades before the cost of the system is recouped, so installing a solar system isn’t suitable for the renter crowd.

2.4 Solar panels work depending on the time of day and the season

There is no doubt that solar panels only output power when there is sunlight, and in night-time conditions or rainy weather, the efficiency of solar panels will be greatly reduced, which means that you will still need to buy electricity from the power company to meet your home’s electricity needs.

2.5 Installing solar panels takes up a lot of space

Solar panels generate electricity by relying on the ability of the sunlight to be captured by the panels and converted into electricity. This also means that the more electricity a user uses in their home, the more solar panel space they will need.

First, this will further increase the cost of installing solar panels. Secondly, taking into account factors such as angle, orientation, shading, etc., and subtracting obstacles and windows, the space on the roof suitable for installing solar panels is very limited, and if the user wants to install solar panels to meet the electricity needs of the home, he or she may have to take up some of the ground space in the yard to do so, thus taking up a lot of space.
