Why Consider Solar Powered Homes?
Water, energy, and food are essential for human survival. In view of this, studies have shown that new energy sources will bring us to a new era that will bring about ecological and environmental protection. We will be free from the harm caused by previous energy sources such as oil and gas, coal, and wood.
One of the energy sources that have become a common part of our lives is solar energy. It has been in use since the 7th century. It was discovered in 1839 by Aleixandre Edmond Becquerel. Since then, other researchers have consistently refined the discovery. You can visit this website to read about the origin of solar panels.
As a result, there are currently solar systems that we can incorporate to power various places such as our homes and even factories. In this article, the major focus will be on the factors to consider when building solar powered homes. But first, let’s look at the advantages of incorporating solar systems into our homes.
Benefits of Solar Systems for Homes
Power generation is the basis of improving the human standard of living. Several methods have been developed for the generation of electricity. However, due to environmental consciousness and the need for sustainable energy, there is a need for an eco-friendly source of power generation.
Solar power generation has proven to be the most promising of all the eco-friendly sources of power generation with high efficiency compared to the others. The benefits of this eco-friendly energy in homes cannot be over-emphasized. They include the following:
Cost
The overall costs of purchase, installation, and maintenance of solar systems for homes when compared to our traditional electric power supply companies are relatively cheap and easier. This makes the systems cost-efficient, saving us from huge electricity bills.
Environmentally Friendly Source of Electric Power
It is eco-friendly because it stems from a natural source which is sunlight. It does not have any byproduct that could be harmful to the environment. Because of the industrial revolution and the use of fossil fuels, the planet is facing environmental problems. But the use of eco-friendly energy as a source of power provides us a way out.
Renewability
The source of energy for solar systems is the sun, which is available to us for a major part of the day. This means that your home will not run out of power if the sun is present. This makes it a more reliable source of electric power compared to other sources.
What Should You Consider When Building a Solar Powered Home?
As discussed earlier, solar systems are evidently a beneficial source of power. But before you install a solar system for home use, there are important factors you should consider.
Maintenance
The installation of the system in your home will most likely be on your rooftop. While maintenance will be required, it will definitely not be a hassle. The panels are completely stationary, so they have no moving parts. There is very little chance of anything going wrong at least mechanically or electrically.
Also, the panel will mostly require cleaning because it is located on the rooftop of your home. There will be bird droppings and dust buildup on its surface. This debris can obstruct sunlight from striking it. Therefore, it is important to maintain your solar panel by keeping it clean.
It might sound like a lot of work, but you can clean it as often as once every week or even once a month. You can do it about one to five times a year.
Location
The location of your home has a very big role to play in the solar system’s efficiency. This is because the amount of electricity that will be generated depends on the sunlight. If your house is situated around tall trees and buildings that cast shadows, it will cause a reduction in the amount of sunlight your panel will get. Therefore, it is necessary to install your solar panel in a position where it can get the most sunlight in order to achieve maximum efficiency.
Coverage Area
This deals mainly with the size of your panel, which is mostly determined by two factors – insolation and the amount of power you need. If you don’t require much electric power, then you need a smaller system. But if your home requires a large amount of electric power to run, then the size of your panel will increase.
Insolation Rate
Insolation is the amount of radiation from the sun that hits the surface of your panel. It indicates the amount of available sunlight that the panel will convert into electricity. Therefore, it is important for you to consider the insolation of your environment.
The greater the insolation, the greater the electricity the panels will generate. You can check out https://energyeducation.ca/encyclopedia/Insolation to read more about insolation.
Cost
In the selection of solar systems, you must consider the initial cost of purchase since various types exist with different efficiencies. You also need to factor in the cost of installation except you want to install it yourself.
Conclusion – Solar Powered Homes
The use of traditional energy sources has over time proved to be detrimental to our environment. And to think that these sources are non-renewable gives us something to ponder about when building solar powered homes.
What if they go into extinction?
Hence, deciding to power our homes with renewable energy is a wise thing to do. We discussed the benefits as well as some factors you should consider before installing a solar system in your home.
