Solar garden lightsOne of the problems that occurs with those who want to purchase solar garden lights or any other kind of solar energy system is that they are afraid that solar power is still something of a gimmick and unreliable.

But, those who own solar garden lights for the most part tend to be satisfied with the product they have received. There are several reasons why these lights can be more useful to people than typical lights.

• These lights work thanks to a PV (photovoltaic) cell. Without this cell, there would be no solar energy. Also, the amount of power generated for the solar garden lights can be greatly altered if things like plants, trees or shade from the home partially or completely cover the PV cell.

• These lights are able to run for several hours at a time without worry of changing batteries or running up an electricity bill. Typically, the solar lights will be able to draw from the PV cell in order to work at night for a period of about 8-10 hours.

The same does not hold true, however, at all times in the year. Because the PV cell is not able to capture and generate as much DC current during the day in the winter months, this directly correlates to the amount of energy provided.

• LED (light-emitting diode) lights are for the most part the bulb of choice for solar garden lights thanks to the nickel-cadmium or nickel-metal-hydride batteries that are used along with them. Although these are fairly new for users of solar energy, recent research has found they are much more efficient than previous versions of batteries.

While these advantages are useful, these lights are not without fault. Perhaps the biggest disadvantage to owning these lights is that they do not shine as brilliant as traditional low-voltage AC lighting does. Depending on how much light is needed, this could be either a large or a small problem.

Solar garden lights are also not useful in places like Alaska or Canada where the winters are long and the days are short.
