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.

Solar Power or the Use of Generators

Every year, the environmental problems are getting worse. Global warming, pollution, and other concerns are now very evident. Many environmentalists are now taking an active part in the hope of saving the world before it’s too late. One way to effectively address such problems is by using solar power. With many households and establishments using generators to back up their power supply, which do you think is the best choice?

Power failure happens in the most unexpected hours and so having a generator can provide the needed power. The portable generators are widely used and you can even find large generators that provide emergency power. If you want to help in reducing pollution and other environmental problems, why don’t you opt for solar power instead?

The initial cost is a very important consideration but you will also need to look in the benefits that you can gain the future. Installing a viable solar power system can be quite expensive than just purchasing a portable generator. However, once you’ve installed the power system, you can already enjoy free unlimited power supply. Maintenance is minimal and you will not spend huge money on it. You don’t need to buy fuel just to run the system because the energy of the sun fuels the solar power system. In a portable generator, you will need to buy fuel to run it and so you will continue to spend money to enjoy power supply.

Generators can be purchased easily, online or locally, and so it’s quite convenient to obtain them. On the other hand, solar power is not that convenient to install and purchase as well. The market for solar power is rather small but because of the technological advancements, the market will soon grow. Today, the best way to obtain solar power kits is through the internet. Anyone can settle for a little bit of inconvenience especially if huge benefits are involved. Besides, after the installation of the solar power system, you don’t need to monitor it often unlike in generators where you will refill the fuel, change the oil and filter, and two times servicing in a year. The solar power system can last for twenty years even with minimal maintenance.

Both solar power and portable generators are efficient. However, when it comes to cost-efficiency, solar power is ahead. As long as the sun shines, energy can be generated. The system can also store energy so that it can be used at night or during rainy days. In a generator, you will need to re-fuel from time to time. You will need to pay for the fuel every time. Sunlight is free but fuel is not and so the cost efficient option is very obvious.

In terms of dependability, solar power and generators are almost the same. Solar power is best used in places where there is bright sunlight all throughout the year. If the period of bad weather is lengthy, all the stored power can be consumed. Generators can be used whether it’s sunny or rainy but the problem lies with the source of fuel. If you can’t refuel the generator, it will not work.

It’s your choice whether you will use solar power or a portable generator. It all depends on your capacity to pay for the device. You can further evaluate these two by reading this article carefully.
