Alternative power sources are of interestman for a long time. Of particular interest in the past two centuries is the energy of the Sun. As the scientists have calculated, it takes three days for the Sun to produce the amount of energy consumed by the entire planet during the year. Most importantly, you do not need to pay anyone for this energy.
Installed on the roof of the building or on one of its walls , you can not worry about the quality of energy, and the integrity of the family budget.
Advantages of alternative energy
1. Free electricity (you only need to invest in the purchase of equipment).
2. Long service life (more than 2 decades).
3. Lack of regular maintenance (only in winter time, solar panels need to be cleaned of snow).
4. Uninterrupted power supply.
5. Ecological cleanliness of a source of alternative energy.
To be honest with readers, let's saya few words about the shortcomings. This is a long payback period (on average about 2 years), dependence on the weather and the inability to provide energy to those appliances whose power is high. As for the long payback period, it is more than offset by long-term operation. Protect from the vagaries of nature will allow special batteries that can accumulate the energy that the solar panels produced for the house, and which was not spent during the day. On days when there is no sun in the sky, and also at night, the power supply can be realized at the expense of the energy accumulated in the batteries.
In what cases is it necessary to resort to alternative energy
- if the central power supply system is not connected to the building;
- if the power supply is strictly limited;
- if the cost of supplied electricity is unreasonably high;
- if there is a need for uninterrupted power supply.
Yes, solar panels can not be called a budgetacquisition. Their cost is quite high, but the benefits are impressive. While the neighbors will lament over the electrical equipment that went out of the storm, nothing like this will happen in your home. Natural cataclysms, a human factor, or total disconnection of electric energy are not terrible for a solar power station. As long as there is sun - there will be energy, and, therefore, light and comfortable in your home!
