Boost the performance of your PV system is crucial. Improved productivity in fact leads to greater production of electricity during the year and therefore the more money you earn the Energy Bill (for those who still benefits from it) or savings in the bill. The action to put in place are few and simple and will illustrate them today in this guide.
How to increase the production of electric energy
First you need to check the insulation of the modules that must always be exposed to sunlight. Usually the plants are installed in the summer or spring, when the star closest to us is up. The technicians have the tools to study the solar movement throughout the year, so they are able to predict any shadows that may arise during the hours of the day, especially in the early morning or late afternoon.
However, this does not always happen. A shadow could not have been predicted. A light pole, a tree, a building. Everything could come between the sun and solar module. A panel in the shade invalidate performance. Not only his, but also of all the modules connected to it in the same string. Where can then remove the obstacle or move the module in the shade.
Secondly, it is always advisable to clean the solar panels, especially after a rain or after days of wind from the south who may have brought sand. There is also the bird droppings, which impairs the efficiency of a module. Just arm yourself with a sponge and water and rinse the glass module. If we can not reach them you have to buy a carton, the same who use the washer at traffic lights. Be careful not to use products abravisi, too aggressive or brushes that could scratch the glass that would jeopardize the operation of the module.
We use solar panels with high efficiency.
At the time of the module, one of the indices that we must take as a reference the efficiency. It is of yield: only a part of the energy coming from the sun is in fact used for the conversion into electricity. We speak of values usually between 13 and 20% for crystalline silicon modules (mono or poly) and of 9-12% for the thin film panels.
On the market there are high performance modules, such as Sunpower and Panasonic. They are unique because they can have efficiencies of 20% against an average of 15%. It means to produce more electricity using the same space occupancy of the module. Obviously we have to take into account higher spending for their purchase.
Solar trackers and log production
An increase in the production of electricity during the year you can have through the use of solar trackers. The modules are mounted on bases with an electric motor that rotates with the movement of the sun. The panels will always be exposed perpendicularly to the sun, so the exposure is high and production increased. A part, however, the electricity produced in the most will be absorbed by the motor itself that needs power for its operation. Higher costs for the purchase of solar trackers.
We always keep a register of production.
We keep a notebook on which we mark the daily performance. Counters is easy to take note of what we have produced during the day. We will then have control of the situation at hand in case of failure or drop in production we will be able to realize immediately that something is wrong and to act now.
It could be a failure of a module, a shadow caused by the sudden fluttering of a sheet that you went to lay on a panel, or even the theft of some form. Let us remember that to prevent theft are on the market excellent specific alarms for solar panels.
