★★★HOW TO BUILD VERY CHEAP SOLAR PANEL FOR HOME★★★
———————————————————————————————————–
It is hard to imagine, but the amount of solar energy falling on the earth’s surface in a week than all the world’s reserves of hydrocarbons and uranium, and yet it is a fact.
All hydroelectric, wind and other renewable sources of free energy in the long run work through solar energy.
It provides water cycle, wind tides, etc.
Unfortunately hydro, micro hydro even bring harm, often unjustified. Require systematic, if not constant maintenance.
However, it is the most stable source of electric current.
Wind farms, especially mini wind turbines do not enjoy constant and depend on the whims of nature. Have a mechanical component and maintenance free.
Solar power, generators, batteries, are directly dependent on the incoming optical radiation. And if you do not make them a roof or canopy, useless in the dark.
The conversion efficiency of solar energy through photovoltaic cells to date is from 7 to 20%, and is expensive.
But there is a certain logic.
Now day electricity is twice as expensive night (you set the two tariff meters?).
It was in the daytime solar panels – a good friend of man.
They can not resort to external sources of electricity, and with the emergence of the legal framework will be able to sell the surplus to the network on daily rates, getting back into the dark of the night tariff.
This also eliminates the need to accumulate power, respectively, excluding the cost of the battery (batteries) and other chores. Although if you use solar panels as a backup power supply, some of the batteries should be retained.
The feasibility of using solar panels in remote places is undeniable.
As a source of direct current solar cells are well established in agriculture, peasant farms, the apiaries, with cattle grazing, field camps, ..
Fuel generator to determine needs in the acquisition, delivery and refueling. Technically complex product and repair.
A significant number of moving parts forced to think about when he loudly say “Everything.”
There are many other costs in the form of noise, exhaust gases, etc. If you see a comparative calculation of energy efficiency or how much the generator is actually no doubt in choosing an independent source of energy.
In the absence of mechanical parts, solar panels require virtually no maintenance.
Solar tracking system, tracker in home solar systems is not justified.
The immediate question of the installation location on the slope of a roof or gable as a solar “nails not pribesh not glued and taped.”
Installed separately on the level of human growth?
Have to take the fork and wait for the night “guests.”
Given the low efficiency of the morning and afternoon sunlight, the efficiency of solar cells with the tracker is increased by 30 – 40%, and the cost increases in two or more times.
It is more logical to buy for that amount additional solar battery + cheap car alarm and get rid of complex electromechanical components.
