HQST 100 Watts 12 Volts Polycrystalline Solar Panel Off-Grid RV and Boat Kit with 30A PWM LCD Display Charge Controller + Adaptor Cables + Mounting Brackets
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.

What are the benefits of solar panels in a house?
The advantages of placing solar panels at home translate into a reduction in the energy consumed, reducing the electricity or gas bill.
If we use solar thermal panels , we can reduce or completely cancel the use of gas or electricity to produce hot water .
With photovoltaic panels we will need much less energy to operate our appliances and lighting.
In case of having an electric car we can charge your battery and get a fuel savings .
These benefits are not achieved only in exchange for the cost of the installation; In addition, the law establishes some tolls that tax its use, with the intention of making the users of these energies contribute the same as those who do not use themHQST Polycrystalline Off Grid Controller Mounting Reviews
There has always been a great debate about whether the Chinese modules are worse or better than the European ones, and many users would be surprised if they knew that a good part of the European modules are made with photovoltaic cells manufactured in China, and the only thing that some European manufacturers do is to put the glass and aluminum frame and then your brand. Just as there are good and bad European products, the same happens with Chinese products. And it’s something that has nothing to do with some unscrupulous sellers selling solar panels of debris, or with defective wafers, at prices suspiciously cheap, or even that, at normal prices.
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.
