Solar Energy - Just "Hot Air," Or A Good Investment?http://energis.com.au/grid-solar-power-system/
Most of us have heard about solar energy and realize it's great for the environment, but many don't know exactly why. Still, it's not just sunshine and roses; before you invest, you need to be aware that there a few downsides as well.
The longer term savings possibilities are perhaps the biggest attraction for those installing solar panels. By setting up solar panels, you won't have to pay monthly bills for electricity which is going to save you money. However, switching to solar is not a cheap exercise. Initially, you're going to have to fork over a big sum of money for the panels and installation, but in the long run you stand to save money and you've basically got a no cost source of energy once you've recovered your initial outlay. Your payback period will evidently be longer if you are a light user of electrical energy, compared with somebody who is a heavy user. You could be fortunate and get assistance with the initial cost from an unexpected source, since your government could extend an inducement for you to install solar panels.
The next most essential thing going for solar energy is that it's environmentally friendly. It's unpolluted as there are no emissions or burning the least bit, unlike conventional fuels that pollute the air with a multitude of gases that are both damaging to the environment and to our health. Basically, solar energy does not lend 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.
Likewise, solar energy is quite discreet as it can be put on the top of buildings, meaning it's not an eyesore unlike wind turbines; but, if you have solar panels on the ground, they can affect the landscape just like wind turbines, so it's important to think of their location and placement. You have to likewise make certain they're installed in a spot that receives a lot of sun, or else they're pretty pointless. They're also discreet in terms of noise and smell, as they make no noise and no bad smells.
Solar energy systems don't require maintenance, except for initial installation and they will last for years, meaning you can set them up and leave them there for many, many years. Of course, one issue is that nighttime spells "lights out" for solar energy. You can set up a battery or some form of backup system to provide energy when there's no sunlight. This calls for extra money, but the solar energy can charge the batteries so you won't need to spend money recharging them.
In general solar energy is certainly worth looking into. Besides the upfront costs, it costs you nothing, and it's beneficial to the environment. If you're wanting to lower your energy expenses and care about the environment, then solar energy seems to be the the way to go.
