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.

Pros

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.

Cons

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 for Homes – Not Just For Rich People

Solar power is free. Well, that is, once you’ve finished installing the solar power system. Today, the homes that use solar power are limited and most of them come from the rich sectors of the society. The cost of installing solar power systems can range from $35,000 – $250,000. However, there are cost effective systems but you need to build them on your own. These DIY solar power kits can be obtained from $200 to $350.

Because of the technological advancements, a lot of homeowners are now able to use solar power at a very affordable cost. In some places, the government monitors the solar power consumption of some homes. Programs were also launched to encourage other homeowners to opt for solar power. For example, when the solar power consumption has reached a certain point, rebates will be given.

The expensive solar power systems can store the energy of the sun effectively in the batteries but the less costly versions are not that efficient. Still, if you try to scour the net, you can find homes that are successfully using DIY solar power systems. In Los Angeles California, a lot of homes now enjoy solar power to the fullest. It is always sunny in this area and it rarely rains. Before, solar panels were really ugly but because of today’s modern technology, the panels are more stylish and can blend well with the existing design of the house. Many homes in California now opt for solar power because of the constant blackouts. According to some experts, California is hoping to achieve a 10% overall consumption of solar power in the area by 2020.

Some celebrities also have solar powered homes in LA like Edward Norton, Julia Roberts, Larry Hagman, and Jackson Browne. Well, these celebrities can definitely afford to pay for the expensive installation of solar power systems. For starters, why don’t you try to install DIY kits? These are more affordable and if you like to do things on your own, this is an excellent project. However, when it comes to electrical matters, you will still need the services of an experienced electrician. The solar power will be connected to your existing electrical supply and so you might get electrocuted if you don’t have enough knowledge about it.

Going green these days is vital to save the environment. Global warming has taken its toll and people from all over the world can now feel the consequences. Using solar power is a very effective way to help save the environment so that you can no longer depend entirely on conventional electricity. Perhaps you’re already aware that electricity is generated by burning fossil fuels. The emissions from the burning of the fuels contribute to global warming. When you use solar power, you can decrease electrical consumption and in turn you can save a lot of money. Say goodbye to expensive electricity bills and save money.

Solar power for homes is for everyone and not just for the rich and famous. If you can’t afford the ready-made varieties, you can create your own by simply following a guided instruction provided by a reputable and established manufacturer of solar power systems. Choose the appropriate system. The size of the system should also be considered so that your electrical needs can be met. Install a solar power system in your home and witness its benefits.
