There is little doubt that more people are getting interested in renewable energy sources to provide the energy needs both in their homes and portably. One such system that fits into this category is solar power. This article will cover the pros and cons of using solar power.

Solar thermal and light energy can be used to provide our homes with power. Solar light energy is used in many portable devices. A major advantage of such systems is that they are clean systems. The energy comes from the sun, so there is no need to excavate and process the raw materials to create a usable energy resource.

Using such systems also cuts down on pollution. It does not contribute to the greenhouse gas emissions. It does not pollute the water supply.

Solar power systems can be expected to last a long time. They are tough-wearing and sturdy. They have to be built to last so that owners can recoup their investments. It turns out that solar power systems last much longer than that.

The costs for maintaining a solar power system are very low. Some components of the system may last decades without any maintenance at all. Solar panels are often warranted to maintain 80% of their efficiency for up to 25 years. Other parts will need to be replaced sooner, but if all goes well there should be no maintenance costs at all for the first five years.

A solar power system is neither too dangerous nor too complicated for most people to run. It requires no supervision from the government or any other agency because it poses no risks. The cost of running the systems is also very low.

There are certainly a few negative aspects of using solar power. Before consumers can have any solar power, they have to make a large investment on the equipment and installation. They will make up this investment over the life of the solar power system but this large up front sum can deter many people. There are more grants and incentives being introduced to minimize this deterrent to getting solar energy.

However the biggest issue with solar power is it’s reliability. Ideally you need a location that gets plenty of sun throughout the year. If you get plenty of cloudy days then your supply may be interrupted or decreased. And it doesn’t work at night. There are ways round this, like storing power in batteries or having a back up system however reliability will always be an issue until solar cells can be made more efficient.

To this extent, many governments are not keen on large scale solar energy plants to power towns and cities and see nuclear power as a better option because it is viewed as more reliable (which many people may dispute).

Given that efficiency of solar cells should increase and the costs will come down, it makes a lot of sense to get a solar panel for your home. There should be a fall back system because of the reliability issue. Most people go for a grid tie system whereby they keep grid power and sell their solar power to the utility company, thus getting a discount or cheaper utility bills. This is a stress free way of using solar power.
