Know the Company that made the panel. – While some companies are dedicated to research to produce better solar panels , others simply dedicate themselves to assembling the photovoltaic modules, before making the purchase, the ideal is to know the company that He made the panel.
What materials were used.– There are 3 types of solar cells . The Monocrystalline is the most efficient and is produced in small cells, so monocrystalline solar panels are smaller and in turn are the most expensive. Polycrystalline, is the second most efficient and is also the most common in the market, since it represents a good balance between the price and efficiency of the panel. Finally the Amorpho which is a thin film of silicon and are the least efficient.

Solar energy saves you money.- The cost of solar panels and other components of a solar system such as inverters and batteries has dropped considerably and it is estimated that it will decrease even more in the future. Even so, it may seem that the cost of installing a system is high. But once installed, you will begin to see important savings in your electricity bill. Depending on the type of installation and your energy consumption, you may end up paying a negligible amount for your monthly energy consumption. This is undoubtedly the most powerful reason why more and more people are switching to solar energy for their homes.Polycrystalline Module Battery Charger Flashlight Reviews
Considerations prior to the installation of solar panels.
To take advantage of the advantages of placing solar panels at home, it is convenient to have some considerations about their installation.
It is important to know the performance we can obtain according to our location, there is a map in which the climatic zones are classified according to the solar radiation or the annual sunshine hours. To capture the maximum solar radiation, we must orient the panels to the south.
It is also necessary to take into account the inclination of the panel that will depend on variables such as use or geographical latitude and a fixed value (18º), which must be added to it, in order to obtain optimum performance.
The color of a solar panel is 100% personal preference. The monocrystalline cells are dark gray-bluish or sometimes almost black; the polycrystalline cells lean towards the blue color, with multiple crystals that reflect different shades of blue. The color of the cell can be selected or changed. However, you can select the colors of the aluminum frame and the back sheet.
One point that is worth mentioning is that the panels with black background work at a higher temperature, therefore lose efficiency. The loss is not significant but the operating temperature of the array will increase, especially in hot climates. If efficiency is your ultimate goal, it is recommended to use panels with a white background; however, an all-black panel is not bad when appearance matters.
