Pros and Cons of Residential Solar Energy System

Harnessing the power of the sun’s ray to create energy to power our house is very appealing. But the question is, “Is everything about solar energy good?”

Looking at the current price of fossil fuel-based electricity, it is quite impractical to convert into solar energy system. However, with the growing concern on the state of the earth, there is really a need to find other means of energy aside from what power plants are using right now. Where do you place yourself?

Whether you are an advocate of clean energy or simply care about where your finances go, looking at the pros and cons of residential solar energy system will help you decide on whether to convert or not.


Solar energy is free. Did you know that the earth absorbs 174 pettawatts of solar radiation? This means that we have more than enough source of free energy to power every house in the world. Unfortunately, most of our energy is still drawn from oil, gas and coal. But in recent years, there is a steady increase of demand for alternative and renewable energy like solar power. It is estimated that the demand for alternative sources of energy will increase by 53% between 1999 and 2020.

Solar energy is clean, renewable and sustainable. Because the energy created from the sun’s rays does not produce byproducts like those from fossil fuel power plants (sulfur dioxide, nitrogen oxide, mercury or carbon dioxide), it does not contribute to pollution. Accordingly, the increase in the use of solar energy and other alternative forms of energy will decrease the demand for greenhouse gases-producing power plants.

The price of photovoltaic cells is steadily decreasing. The demand for solar panels has risen by 57% in the United States in 2007 and is steadily increasing on a monthly basis. The increase in demand results to the improvement of solar technology as a whole. The prices of photovoltaic cells have declined on the average of 4% every year over the past 15 years.

Solar panels can be installed on most rooftops, eliminating the problem of finding a suitable place for installation. Solar panels require little or no maintenance. The original photovoltaic cells technology is used for most satellites orbiting our earth today which are not maintained at all. Many solar panel manufacturers give 25 to 40 years warranty on their products.

Because most areas of the country receive a substantial amount of sunlight throughout the year, solar panels can be installed anywhere.

Many states in the country give tax credits and rebates to households who want to install solar energy system. Check with your state government the cost of these incentives.


While the prices of PV cells are in constant decline, the cost of installation is substantially high compared to the current electric cost. But the good thing is, after your initial cash out, you don’t have to pay every month on electric bills for the rest of your life.

On areas cities and areas with heavy pollution problem, solar energy may not work as fine. Weather can also affect the efficiency of solar energy. If it is raining, overcast weather or if there is a hurricane, the solar panels’ efficiency is decreased.

You are only producing energy during day time.

These are general pros and cons you might encounter when considering the conversion to solar energy system. It would be best if your decision is based on location, cost, budget, rebates, tax credits and practicality.

Many More Jobs Solar Power Creates Than Coal

This Simple Graphic Shows How Many More Jobs Solar Power Creates Than Coal

In recent weeks, Donald Trump has spoken on several occasions about his desire to revive the coal industry for the sake of preserving and creating jobs. But 2016 data shows shifting focus away from sustainable energy sources back to fossil fuels may preserve the jobs of those in the coal industry, the net effect will ultimately cost America hundreds of thousands of new jobs per year.

Solar Roof Energy Panels

Writing this article for you was a pleasure, I hope it be likewise for your to read it.

The process of installation of solar roof panels normally relies on the use of some form of mounting systems that keeps the photo-voltaic devices in its place. A solar roof technology that delivers us with alternative energy made from an ordinary number of solar roof panels is the right alternate when it comes to economising money and producing heat and electrical energy in a very clean and environment-friendly way. Solar roof panels can also be added to the house construction after the building of the house, yet, the present-day inclination is to integrate the system in the roof during the very construction process so to ascertain a longer lasting structure of the solar panel.

The positioning angle of the solar roof panels is ordinarily a standard one, but the main subject here is the way to make the panels stay open to the sun for a longer period of time. Most experts in the field claim that the south orientated solar roof panels acquire more sun exposure, and if you purchase some west or east orientated ones, in this case a higher number of panels will be needed. Nevertheless, not all roofs allow south orientation, and the architecture of the house as such does have a good word to say in the matter.

Usually most solar roof panels will be positioned at a distance of three or four inches from the roof, they are lightweight so that you should not concern about the pressure level they will add to the house structure. They attachment is safe and durable, and the matching with the house architecture and design is out of the question. Once the building and installation of the solar roof panels is complete, you can savor in the comfortableness of your home without any upkeep costs whatsoever. Most homeowners from around the world favor such products due to their wide lastingness and high economy potential.

Before we engage in decision on what type of solar roof panels to install, it is advisable to make a simple inquiry to learn what options you truly have. You do not have to buy the most expensive solar system, but an intermediate one should be enough for any regular household. When it comes to the governmental policy particular to your country it could also work for your advantage in terms of tax returns, but the best way to make a determination is to get all the information you can. All in all, solar roof panels should be paid from the heat and energy savings over a period of three to five years, and then you can think that all your home utilities function for free which is a great feeling to know.

How Solar Power Generation Can Work for You

Solar power is quickly becoming a popular option. You might be surprised to learn how it and solar power generation actually work. Because a lot of people do not understand the ins and outs of solar energy, they may think they could not benefit from it. Truthfully, not only can we benefit from solar power, but so does the environment.

In order to understand how advantageous solar power is, you first have to know how it works, at least to a basic degree. It uses some method, some technology, some technique, to capture and store sunlight – which contains solar radiation. It then converts the powerful energy into solar power.

Naturally, the sun is a vital part of solar energy. Its basic nature is the reason harnessing solar power can be so beneficial. After all, it is a renewable resource. We will never run out of it. The sun is eternal, at least as it pertains to those of us here right now, and many generations after us. It is without limit. We can never possibly use all of the sun’s energy. Even after being used for thousands of years, it is still going strong. It releases enough radiation in a few seconds to power the entire world.Many solar power advantages also apply to the environment, the ecosystem, the ozone layer – you name it. It does not create pollution. It is a completely clean alternative source of energy. It does not produce emissions either, and it releases absolutely no contaminants into the air.

Nowadays, solar panels, a form of solar technology, are the most common methods of solar power generation. Panels have been used since the beginning of the nineteen seventies. Back then, it started with people placing solar collectors – they collected and stored heat, converting it to energy and power – on op of their roofs. The power which was collected was able to power up their appliances.The new evolution of these collectors are solar panels. They can be installed directly inside the home, and still effectively work to capture solar energy. Several people are able to use the sun’s energy during the day, while running power through the energy stored in the panels’ batteries at night.

There are also many ways in which solar power can be used. You can already power your home with it. Scientists are now working on solar powered cars as well. New solar technologies are emerging every day, so it is impossible to tell what the sun might be used to power next. It is safe to say that there is no end to the possibilities.That is another advantage of solar power – because the technology is advancing consistently, and quite quickly, the current methods of generating solar power are going to get simpler, more practical, and more accessible to everyone in the world.

Solar cells are another way of generating solar power. The energy they generate is used to char up and power up such items as laptops, wireless devices, and cell phones. The solar cells allow solar powered to be stored in those items’ batteries. An inverter allows it to be converted into AC power.

Lastly, you will not be changing a lot of light bulbs, buying a bunch of new batteries, or endlessly replacing cords. In that way, it is also money saving. It is also time saving and much more efficient. In addition to producing your own power, for instance, solar energy can become a new light source.
