During the final years, have been growing alternatives of unpolluted and renewable energy sources, the most popular: Solar power and wind energy.

The technology has advanced so much, and in the present day exist in the market many options underneath the scheme of “do it yourself” guides that supply teach you how to build a photo voltaic panel or wind turbine on your home.

TIP: If you are not the sort of person who likes the Do It Yourself” guides, you always can hire some technician guy who will do the “dirty” work for you.

This know-how has been developed by issues that aren’t unknown to anyone: High air pollution of fossil fuels and its consequences: Floods (Mexico, Philippines,USA, etc), drought (For 2017, the UN says, about 70 percent of the worldwide population can have problems to access to contemporary water), climate changes, etc.

Today, is entirely up to us make some about enhance our environment, technology has completed its part

TIP2: Once you’ve got the knowlege, what about to set your individual and worthwhile “evergreen” business by selling solar panels in your city? interesting, don´t you think?

We will review the 4 main parts of a photovoltaic system or photo voltaic panel system:

1.-Solar cells.-

Are a element of the photovoltaic system, are extremely fragile, not electrically isolated and have no mechanical support, so, once made, must be assembled within the proper strategy to form a single construction rigid and hermetic: Photovoltaic panel.

Solar cells are electrically connected to each other in collection and / or parallel, in order that the voltage and current provided by the panel is increased to fit the desired value.

2.-Photovoltaic panel:

Modules or panels are the main elements of any PV System (Photovoltaic system for short) and its operate is to seize the incident solar vitality to generate electricity.

Most of the solar panels are constructed first by associating cells in series to realize the desired voltage level and then combining in parallel a number of associations of cell lines to realize the desired current level.

3.-Batteries:

Batteries or accumulators are used to accumulate the power that the panels generate day by day and for use in time where power consumption is increased than the generated, as at night.

Another necessary function of the batteries is to provide a current larger than the photovoltaic system can deliver for some cases: This is the case of an engine which within the boot time can use a present of 4-6 occasions its rated present for just a few seconds.

Moreover, the battery provides a steady and constant voltage unbiased of the incident mild conditions, which often is the most suitable for the operation of electrical appliances.

4.-Charge controllers:

Bearing in mind that solar vitality is variable and seasonal, this can be very important to have a device to manage the relationship established by battery and the generator system (PV Panel).

Suppose that consumption is similar for all days of the year, to calculate the required number of solar modules that we will need to powered all our appliances, must be based on winter radiation to make sure the correct functioning of the system, because that’s the worst time of solar radiation of the year.

But when summer season arrives, the value of radiation may be duplicated, so that production shall be twice that calculated for the winter, whereas consumption is the same. If we do not need a regulatory system, there can be an excess supply that would have the ability to boil the electrolyte with the consequent loss of water and deterioration of the group accumulator (battery), as a result of the charge isn’t regulated.

Regulator or cost controller is the system that manages the direct consumption of the batteries, and avoids overloads or deep discharge, thus extending its life. It additionally generates alarms based mostly on the state of the charge.

Regulators are put in between the generator and battery system, taking from these final one the energy it needs for its operation.

In my subsequent article, i will talk to you a little bit bit of inverters, one other main component of a PV.

Thank you.
