Residential Solar Panels

Residential Solar Panels: Solar panels - Power the Future
Solar panel - is characterized as a source of electric current through the photovoltaic cells. The advantage of solar panels due to the lack of moving parts, their high reliability and stability.
On the market solar cells can be divided into several classes:
- Low-power solar panels used to charge cell phones, PDA and other similar electronics. They are characterized by small area of the photographic plates and the relatively high cost.

- Universal solar panels made to supply a wide range of consumers in the field. Price and quality can vary within very wide limits. Therefore, when buying a need to consider each option separately.

- Panels of solar cells. Typically, a set of photographic plates, fixed to the substrate.

Exploitation of solar panels
Using solar panels should seek to ensure that they were placed on maximum illumination spot and covered the same way. Necessary to take measures to avoid mechanical damage batteries, and also a direct impact on them of moisture and dust. If transportation is necessary to avoid shaking the solar panels.

Observe the temperature regime of solar cells, which is listed in their passport. This is usually -40 ° +50 ° C. In summer, in hot weather is necessary to have solar panels on the surface exposed to low heat, for example, cutting the white matter, or shiny aluminum foil. In this case, they are poorly heated and provide a satisfactory job is located on top of their solar cell.

It should be noted that nickel-cadmium batteries also perform poorly at high and low temperatures. Lowering the temperature of the battery is below 0 ° C leads to a significant reduction in their power.

How much you can save by using solar heating system?
The intensity of sunlight, for example, summer and winter is different. We can judge the efficiency of solar systems, by calculating how much solar heating system provides the necessary volume of domestic hot water. On average, for a house or apartment, the ratio is 60-70% depending on the region. From May to October, solar energy will almost completely cover all domestic needs in hot water. In the transitional months, solar heating can be advantageous to maintain the heating system, greatly reducing the consumption of gas.
