We're probably all aware that using solar energy will help combat global warming, despite the fact that we don't really know how. Still, it's not merely sunshine and roses; before you invest, you have to realize that there a couple of downsides too.
The longer term savings promises are probably the greatest attraction for folks setting up solar panels. Drawing your energy needs from a solar installation at once begins to save you money through not having to pay for electrical energy. There is a catch, however; setting up solar panels is not cheap. Initially, you're going to have to fork over a big sum of money for the panels and installation, however in the long run you're going to save money and you've essentially got a free power source once you've recuperated your investment. Your monthly savings is apparently important to how long before you really enjoy free power; so if your monthly bill is big, it will take less time than if you have a modest electricity bill. Some governments provide motivators for making the switch to solar energy, which might help towards the cost of installing solar panels.
The next most essential thing going for solar energy is the fact that does not harm the environment. Solar energy generation does not involve any combustion or emissions, unlike conventional fuel sources, which is the reason it's called "clean" - the direct advantage being that it is not harmful to the environment and our health. Essentially, solar energy does not contribute to the issue of global warming and it doesn't contribute towards acid rain either. The energy buzz-words, renewable and sustainable, are pertinent to solar energy because it will be available to us as long as the sun continues to shine.
Solar panels, which are the "engines" of solar energy, are basically flat and if set on rooftops are not obvious - if you set them on the ground, though, they can be as hard on the eye as wind turbines, something to be considered when determining on their location. Naturally, if direct sunshine is unablle to reach the panels, they would be useless, so they need to be situated accordingly. Likewise, solar panels are noiseless and odorless, so draw no attention in this manner.
Solar energy systems don't need upkeep, other than initial installation and they will last for years, meaning you can set them up and leave them there for many, many years. However, one worry is that nighttime equals "lights out" for solar energy. No sunshine doesn't mean no energy though, because a back-up system such as a battery could be put in place. The only cost here is for putting them in place, because they are going to be recharged free of charge with solar energy.
In general solar energy is surely worth looking into. It will cost you a bit to to have it set up, afterwards it is going to save you money over time, added to which there is no damaging effect on the environment. If you're aiming to lower your energy bills and care about the environment, then solar energy seems to be the the way to go.
