In recent years we have seen the emergence of lithium batteries applied to solar energy, especially from the advertising campaign undertaken by Tesla with its famous Powerwall battery. However, the Tesla Powerwall is not the only battery system on the market or the best, in fact we can only recognize Tesla for having promoted, through its campaign, both solar energy for self-consumption and the lithium battery applied to the home. As for the reference brands currently used are BYD , LG Chem Resu and Axitec Axiestorage . 

However, despite the many advantages that the lithium battery has over the traditional lead acid battery system, few users are currently deciding on lithium technology. From Cambio Energ├ętico we are betting on the introduction of this technology and for this this post. Let us begin

If we compare the prices of a lithium battery and a lead-acid battery, obviously the lithium battery is much more expensive. However, if we compare the price at the end of the useful life of each battery, we will see that lithium is cheaper.

Logically, not all lithium and lead acid batteries have the same characteristics, therefore we are going to analyze the BYD battery and a generic type of OPZS lead acid batteries , which are the most versatile and durable type of lead batteries. Therefore, at the end of the battery system life, the lithium battery is much cheaper than the classic lead acid battery .

To this we must add that the charging of the lithium battery is much faster and therefore with the same amount of solar panels we can enjoy much more energy. As we can see, lithium is a much more efficient technology than the usual lead-acid batteries (GEL, VRLA, OPZS, OPZV, open, monoblock).

Regarding the negative aspects, it should be noted that lithium is a mineral whose distribution, in contrast to lead, is concentrated in a few countries in the world, so it can create an energy dependence on these, such as the one we have now with oil . Its price, like oil, could be affected in the future by possible instabilities in these countries. 

We are in renewable energies to bet on energy change, as our name indicates, and this change must be ecological. It is in this aspect where the lithium battery system fails from our point of view, especially due to the type of mining necessary for the extraction of lithium, which is carried out in the open pit and in many cases in countries with few environmental protection measures. environment and people. This is undoubtedly a pending issue.  

Unfortunately, we start from the premise that none of today's battery system are completely environmentally friendly - lead heavy metal technology is not either. Therefore, a call should be made for the reasonable use of batteries and energy, even if it comes from renewable sources. However, lithium has a great advantage in terms of energy consumption and therefore in terms of the carbon footprint. Let's compare a BYD Lithium battery with a generic OPZS battery.

We're back to close the chapter on the wine labels with this latest article on the subject. In our last post, we discussed the different printing processes and embossing techniques available to you in order to structure your small paper surface so that it best reflects the uniqueness of your wine. Today, we are going to take a look at the gilding which has the power to give a luxurious aspect to your product and which allows to restore down to the smallest detail. The choice of paper is also important, in front of a large panel you will have to know what you want to transcribe on your  wine labels , a modern or more traditional effect. THE INCARNATE CLASS Hot stamping allows a wide variety of colors. There are many brilliant, satin or matt colors that can be tinted, gold, silver, red, green, blue, pearl or even white gilding… The choice is considerable.This technique allows a raised or flat impression  wine labels   and embellishes your dressing by giving it a shiny and luxurious


The new house is the dream of many people. Several realize the dream, but face an exhaustive stage: change. It's time to box things up, but where do you start? Do not worry.

Transport The first step is to choose a good transport, furniture movers   because it will be this step that will decide in what state your things will arrive in your new home. The points that need to be considered are: Costs - Do not close with the first company you contacted. Research, quote the values ​​of competitors to find a service similar in quality and at the lowest price. Insurance - See if the carrier has insurance, so you don't have to be apprehensive (a) at the time of the move. Packaging - Look for carriers to pack your things, as this saves you from the heavier services. Delivery procedures - See how the procedure proposed by the companies will be, choose the one that suits you best. Complaints - Nowadays, with the inter


Surfing the internet, we have seen opinions of several people who have had their automatic garage door installed or simply an automation and have had various problems with the installation company. This happens when someone only puts the price as a condition for choosing their installation company. This has its logic, but today we all want to sell, but it should not be at any price.We are going to give you five essential conditions so that you can choose with a minimum guarantee the company that suits you best to install your door. You must opt ​​for a company that is already consolidated in the market. This is because the large brands of  doors and automation only grant exclusivity of their best products to companies that defend their image and have the necessary resources to be able to serve the end customer, since after all, their greatest publicity is that the  garage door  that they already have working in the street are installed by professionals and have a perfect operation for
