Many people have already realized the benefits of solar energy and solar systems. Solar systems have a positive impact on the preservation of the environment and significantly reduce electricity costs. Here’s a list of all the financial and environmental benefits of solar home systems for domestic use.
The financial benefits of solar systems
The amount of energy savings by using a solar system depends on: place of residence, house size, number of sunny days during the year, type of system, type of system, and so on. Installation and maintenance of these systems require an average of 10,000 to 20,000 dollars for household needs. For those who can’t afford this amount of money, there are solar systems that can be obtained through leasing. Leasing a solar home system allows homeowners to install all the necessary equipment for solar heating with only a small amount of money.
According to a study in the United States (from 2011), an average twenty-year savings by using solar systems can be over 25 000 dollars. The studies were conducted in the following countries: California – $34.260, New York – $31,166, Florida – $33,284, Texas – $20,960, Hawaii – $64,769. Also noteworthy is the fact that the average American household uses about 900 kWh per month. Of course, for other continents apply different data about these savings.
According to the experiences of some countries in Southeast Europe, the data are a bit different. The average electricity consumption of a four-member household is about 450kW/ h per month. Well placed solar panels (with total panel surface about 130 square meters) can save up to half of the annual costs for the electricity bill.
Since 2000, the annual energy costs in the United States have risen an average of 3.75%. One typical American family spends about 150 dollars each month for electricity. It is approximately two thousand dollars per year. The price of electricity is constantly growing, and household needs for this energy are higher than in previous years.
Here is another one interesting study about solar home savings, by the Lawrence Berkley National Laboratory.
- Adding a solar home system increases a household’s resale value about $ 50 per watt
- A 3.1kW system can add 17,000 dollars to your home’s value
- Houses with solar system sell faster (about 15 %) than homes without them
Environmental benefits of solar home systems
From the standpoint of energy, solar energy is a huge energy source that can meet human needs for a very long time. The solar energy that reaches the Earth’s surface during only 6 hours is enough to satisfy the annual world energy needs. Recommended reading: Frequently Asked Questions About Solar Homes.
Ecologically speaking, it is pure energy whose energy technologies do not pollute the environment. Solar energy is transformed directly into thermal or electrical energy, enabling fast implementation in all energy processes.
Modern solar systems enable the utilization of solar energy throughout the year. They do not emit carbon dioxide (and other harmful gases) and don’t pollute our environment. In contrast, fossil fuels are becoming more expensive, and their reserves decreased. So it’s not surprising that more and more people are opting for solar home systems.
