Advantages and Disadvantages of Solar Panels at Home as A Power Source

The sun is a powerful source of energy, harness this power by installing solar panels to make a significant difference. Solar energy is now proving to be very beneficial, not only for the environment but also for the economy. Although widely criticized for being expensive or inefficient, solar energy has become a major source of energy for more families due to the availability of solar panel grants, as well as increasingly competitive prices in the market. Here are some advantages and disadvantages of solar panels for your home we compiled.

Advantages of Solar Panels

Renewable Energy Sources

Among all the benefits of solar panels, the most important is that solar energy is a truly renewable energy source. It can be utilized in all regions of the world and is available every day.

We cannot run out of solar energy, unlike some other sources of energy. Solar energy will be accessible as long as we have the sun, therefore sunlight will be available to us for at least 5 billion years when scientists think the sun will die.

Reducing Electricity

Bills Your electricity bill will go down. How much you save on the bill will depend on the size of the solar panel and electricity or heat usage.

In addition, you will not only save on electricity bills, but also the possibility of receiving payments for the excess energy that you channel back into the grid if connected within a region. 

Wide Range of Applications

Solar energy can be used for a variety of purposes. You can generate electricity (photovoltaic) or heat (solar heat). Solar energy used to generate electricity in areas without access to the energy grid, to purify water in areas with limited clean water supplies and to power satellites in space.

Low Maintenance Costs

Solar energy systems generally do not require much maintenance. You just need to keep it clean, so cleaning it a few times a year is sufficient. When in doubt, you can always contact a specialized cleaning company, which offers this service.

Some of the most solar panel manufacturers offer a 20-25 year warranty. Also, since there are no moving parts, there is no wear and tear. The inverter is usually the only part that needs to be replaced after 5-10 years as it continues to work converting solar energy into electricity and heat.

Apart from inverters, cables also need maintenance to ensure the solar power system works at maximum efficiency. So, after covering the initial costs of the solar system, you can expect very little spending on maintenance and repairs.

Technological Development

in the solar power industry is constantly evolving and will increase in the future. Innovations in quantum physics and nanotechnology can potentially increase the effectiveness of solar panels and double, or even triple, the electrical input of solar power systems.

Disadvantages of Solar Panels


The initial cost of buying a solar system is quite high. This includes payment for solar panels, inverters, batteries, cables and for installation. However, solar technology is constantly evolving, so we can assume that prices will fall in the future.

Depending on the Weather

Although solar energy can still collected during cloudy and rainy days, the efficiency of the solar system decreases. Solar panels rely on sunlight to effectively collect solar energy. Therefore, a few cloudy rainy days can have a noticeable effect on the energy system. You should also take into account that solar energy cannot be collected at night.

On the other hand, if you also need a water heating solution to work at night or during winter, thermodynamic panels are an alternative to consider.

Expensive Solar Energy Storage

The energy must be used immediately, or it can be stored in large batteries. These batteries, which used in off-the-grid solar systems, can charged during the day so that their energy used at night.

This is a great solution for using solar energy throughout the day, but it is also quite expensive. In most cases, smarter to only use solar energy during the day and draw energy from the grid at night (you can only do this if your system networked).

Uses More Space

The more electricity you want to generate, the more solar panels you will need, because you want to collect as much sunlight as possible.

PV solar panels take up a lot of space and some roofs are not big enough to fit the number of solar panels you want. An alternative is to install some panels in your yard but they must have access to sunlight.

Associated with Pollution

Although the pollution associated with solar energy systems is much less than with other energy sources, solar energy can associated with pollution.

Transportation and installation of solar systems have linked to greenhouse gas emissions. There are also some toxic materials and hazardous products used during the manufacturing process of solar photovoltaic systems, which can indirectly affect the environment.

However, solar energy pollution is much less compared to other alternative energy sources. More than that, solar panels , for example, just need to be wiped.
