Why you should consider solar energy?
Despite the recent publication on the technology of solar energy in the United States in recent years this technology has existed for many years. Its applications in the aerospace and military sciences have to be very viable and useful. In addition, the high cost of energy in Japan and some European countries, the technology of solar energy in commercial and residential buildings has been used for over a decade. In fact, governments have to subsidize long-term commitment to technology, solar / wind and appropriate incentives to justify their costs.
There are several advantages in the short term and long term from the installation of solar panels for homes and businesses. Solar energy is a great way to get the power of Mother Nature offers free use and there are positive results from the use of solar energy, there are many, both for his personal benefit and for the benefit of mankind. Solar energy will also contribute to the consumption of traditional fossil fuels and have a positive effect on the environment.
Many benefits are accompanied by a shift to solar energy. First, annoyed to pay given the current prices for fossil fuels in order to save the monthly energy costs is a direct benefit. On average the cost of public services in the past 30 years have increased by almost 7% and an expected increase of 10% per year for the next few years do not be too far. By installing solar panels for homes and businesses, reduce their consumer benefit rate be reduced drastically and also an increase in utility prices, that is, the more money you can save. Because solar panels require very long-lived products, the minimum maintenance and are backed by manufacturer’s warranty of 25 years, long-term tax benefits are also impressive.
The technology is mature enough?
For those who have no doubts about the maturity of this technology, it should be noted that the technology of solar energy has many advances in technology and can be found in the average age for residential and commercial applications. Of course, like any other technology that will surely make further progress in the future. However, the price for the latest technology is also very likely that progress accordingly. The final product remains the same old power can be produced more efficiently.
The efficiency of solar cells in the majority of issues that the area available for installation is limited. If you have enough space to install a solar system in the correct size, then the efficiency is unnecessary, because what counts is the output of the system. Therefore, improving the efficiency of future panels not so important for those who have enough to accommodate today’s technology. The decision to produce solar energy with current technology, to wait in comparison, more efficient panels in the future could certainly justify a better return on investment in the long run.
The durability of the plates are being honored today, most manufacturers guarantee their panels for 25 years! How many high-tech products on a long warranty period? However, a comparison of the energy industry and consumers of high technology on the economy of scale does not compare to a good apple to apple. In the energy sector due to the constant demand inevitably increases the cost and energy increases, the relationship between work / watt also linked to the rise or at least remain constant over a short period. By late afternoon, the output of a solar system nearly constant for a particular investment over a longer period (eg 30 years), during the lifetime of most high-tech products is less than 4 years.
A better comparison would buy a car. In recent years, an average new car costs about $ 30-40K. After 10 years, the car can be almost worthless. On the other hand, an investment of $ 40K in a solar energy system and income from day 25 or 30 years to produce.
Does it make sense financially?
To understand and be able to analyze the financial viability of investment in solar energy, we must understand the fundamentals and their respective areas, and projections. We could start with the cost of energy in the last 30 years, on average, the cost of utilities grew at a rate of 6.7%, and the projection for the next 20 to 30 years 10% or more can not be far.
The second variable is the price per watt of energy from renewable solar energy in particular. In a typical system, the price of solar modules, inverters, and the cost of installation as a whole is relatively constant at a rate of about $ 8.50/watt-DC. (About $ 0.50 additional cost per watt AC costs)
The third variable is hours and electric utility costs. The Civil Service complicated schedules created to preserve the profitability upright. As mentioned above, these prices will inevitably continue to grow in the future. However, the crucial point to note is that if you can in a solar system that have become essentially an electric utility, and therefore investing, they also benefit from the increase imposed by the utility companies. In other words, if the consumer is sold at a price higher than the rate to float and sell energy at a rate higher than the benefits.
Given these variables are electricity tariffs and schedules for various residential, commercial or agriculture. In terms of speed / time there is a threshold of money if a solar system makes sense or not. If you pay more than this threshold, then it makes sense to invest in solar energy. This threshold may be determined by calculating the return on investments available. (See next page)
In thinking about the number of years the return on investment can not be a good way to see a system of solar energy. The reason is that if one considers, for example, to pay for six years, say $ 30000000000 in solar, then should not we ignore the remaining 20 or more years of continued strong results from this placement. This amount will most certainly help a lot of income with low maintenance costs.
Another point is the recognition for the installation of a solar system on a property. The solar system is installed, you certainly increase the value of your property, provided that the initial cost of the system, if not more.
Is this a good time to install the solar system?
The simple answer is that now might be a good time as any to be. The proof of this assertion lies in the fact that once they have invested, and a solar system which are virtually a utility installed. This current is a rate that produce the system with a conservative projected increase of 10% or more per year designed! And this system requires minimal maintenance for the next 25 years! Is not that sound like a better investment than other systems we know today?
Of course, depending on their energy consumption and usage of time / may or may not be a good candidate for an investment in the solar system. There are some software tools available that help to analyze whether it can be a good candidate and help make an informed decision.
