How to choose the best solar panel for your house?
they also incorporate materials and sustainable operations to have a more eco-friendly home. Photovoltaic systems or solar panels are very important because they can generate energy through an organic and natural process, so it is almost imperative to start incorporating them into our house. So, take note, we will share the advantages of having this system in your home.

Find out how much you usually spend in kw/h per day:
You can check your electricity bill, or consult the electric company. This will help you make your choice by calculating your consumption.
Where would you place it?
Remember that your panel should give sunlight in the most powerful hours of the day, which covers from 10 to 3 in the afternoon. When you know where you will locate it then it will also be easier for you to know the size of panels you need.
Monocrystalline or polycrystalline.

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.
