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.

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.
The theoretical yield of monocrystalline is slightly higher, but also its price.Watts Solar Panels Tempered Glass Reviews
Characteristics of solar panels
Solar panels work with renewable energy, that is, from an inexhaustible source of energy such as the light emanating from the sun. They need a minimum maintenance, one more reason to have them installed at home. Its approximate lifespan is 30 years.
Although the money that is needed to invest for the purchase of solar panels is not less, the energy savings achieved through its use is reflected in the monthly electricity bill, for which there will be less to pay (as long as you have to resort to the use of conventional energy in exceptional cases). In that sense, it can be said that the money invested is recovered in the first months after the purchase was made.
The installation of solar panels is increasingly requested by people, something that contributes to the care of the planet and the cheapening of the devices.
