Solar power equipment, including the panels themselves, has become both smaller and more efficient as solar conversion technology has improved. Where once a gigantic solar panel equipment area was required, today's solar energy generation can be accomplished very unobtrusively, usually with a device in your existing electrical closet or attic, or even in your basement. The panels themselves are smaller today, which allows you to harvest more solar energy from the same exposed surface area.

Perhaps the most expensive part of solar power generation, in relation to actual size, is the converter itself. Since a majority of household appliances use alternating current, and electricity is direct in its natural form, not only does the solar energy have to be converted from raw energy into electrical current, but that current will need to be inverted. And while these devices have become noticeably smaller and cheaper, wave inversion is a costly technology. For items that run on natural DC current, the conversion cost is much lower, as there is less solar power equipment involved.

There is more good news for those who want to use solar power equipment, though. Almost everything in your home, even those that plug into your AC outlets, use direct current internally. Even your computer uses DC, as the power supply provides an inversion and feeds low voltage power to the individual components. As solar power installation becomes more popular, you will begin to see devices that can be plugged into your own private DC grid, using solar power equipment. Just using solar power equipment to recharge your cellphone would be a savings of dollars every month, and that is only the tip of the iceberg.

As I advise everyone, start with a small, complete array of solar power equipment. Set it up and find out how easily and cheaply you are able to supply a portion of your own home energy usage first-hand. After that, you will be eager to enlarge the system, and broaden the scope of solar power equipment being used. Most people only think of electricity when they talk about solar power equipment, but it is important to understand that other methods, such as radiant heating, may also be employed, providing solar energy for homes in a ready-to-use form that indirectly reduces energy cost by requiring less energy to be used.
