The cost of fossil fuel and other traditional energy that we are using is going up day by day. More over these ways are contributing in global worming. Therefore, the idea of using alternative energy is spreading worldwide. A number of companies are offering different types of products based on alternative energy. Among them products based on solar power are at the top of peopleís choice. Solar energy is the best among all types of alternative energy as it is found in abundance, never causes any harmful effects on environment and very flexible to use. These devices don't produce harmful gases and last longer than any other energy based device.
The most popular solar energy based product is solar powered battery charger. Some of them are used to charge MP4 players, mp3 player, mobile phone, PDA, PSP, any gaming devices and I Pod and such small electronic gadgets. Some chargers can even charge car battery. These products offer a wide range of advantages.
However, itís better to check whether these products are really working or, not. Most of the small chargers need to charge under the open sun and donít perform well if it is placed behind a windowsill. Another type of solar charger helps to charge battery of cars and other machines. These are proven as a great back up energy.
While buying any of these chargers a buyer should focus on the following things:
- Backup time
- Installation service
- Power storing capacity
- Charger controller (for car battery)
Like any source of energy, solar energy also has some disadvantages. A very small battery charger cost a lot and other kind of chargersí purchase and installation cost is really very high. However, this is one time cost. Sometimes clouds, limited sunshine, mist, water vapor, pollution are the reasons of the incompetence of these devices. Moreover, at night solar panel and chargers literary become ineffective. Therefore, the power storing capacity is a very important option while buying solar chargers.
More research is needed to improve solar energy based devices. This energy source has a great possibility to flourish as an industry.
