Solar power is a pretty useful energy source. This is a fact that had to be driven home to the public for a number of years before people finally got the picture and began investing in solar panels for their homes and business to cut down on expenses.
Even if it did take a while before the solar panel bug kicked it, it did finally become a natural enough presence that manufacturers began catering to home based solar power. When solar power was first introduced, we became aware of some issues surrounding the commercial use of solar panels that couldn't be ignored. The first problem had to do with bulk and the second had to deal with expense.
First off solar panels are often either bulky and huge or numerous. They have to be. A car's length worth of solar panels would only be strong enough to power an electric hair dryer. Which means that there would need to be 10 times as many to power something that we'd probably use for hours (i.e. a computer). We take the use of electricity for granted when it comes to things like that, never considering just how many watts of power we're using to simply turn on something like a microwave or lamp. So to reiterate, the more solar cells you have, the more power you collect. The problem is that we're in the age of portability and no one wants to walk around with that many solar cells plastered everywhere just so that they can listen to their iPod. Accessibility equals desirability and even at home, the easier it is to work with or move something, the happier a consumer will be.
The second issue that arose was the price of a solar panel. A single panel could run someone anywhere from $100 to $200 dollars. Because anyone buying one solar panel will usually end up buying many (refer back to the first problem listed above) a solar panel system that was powerful enough to power an entire household could cost a homeowner thousands of dollars. Not including the price of installation and renovation, and ect.
Solar panel technology has been improving by leaps and bounds however, and though the problems of the past still make themselves known every now and again they no longer apply as widely as they once did. You may be wondering what that means for you, the consumer. Well what that means is that there are currently more solar panels designed specifically for home owners in mind. These panels are a lot cheaper than the solar panels of old and even better they are lightweight because they're slimmer. This has a lot to do with improved battery sources as well as improved methods of recharging the solar cells.
Whether you decide to have solar panels installed on your home to help reduce your electricity bill or if you have them put in just to feel like you're doing something in an effort to save the world, solar energy is and has always been a pretty useful energy source. And now that it's also becoming more practical and affordable, everyone can admit to it and make changes accordingly.
