Steps to Choose the Perfect Solar Panels

Real Estate Agent with Daily Real Estate Update

If you live in a private house, own a business, or just would like to decrease the electric bills, solar panels are the perfect option. It is an affordable and constant power supply that works by converting solar energy into electric current. The best way to achieve maximum electric power is to use a special system of solar batteries. 48 volt solar panel is a unit for maximizing sun power for all housekeeping systems. However, if it is not possible to obtain panels with such a voltage, it is recommended to connect the items with a lower voltage in series, which still provides 48 volts. A complete system of 48v solar panel is made up of several elements:

  • Solar panel


  • Controllers


  • Accumulators


  • Other items

First of all, the client has to understand the types of solar batteries to choose the best option. Here are some highly important steps for choosing the right model of these units. You have to be familiar with the types of products, prices and quality features, and the warranty possibilities.

Choose the Right Type of Solar Panel



Before you make such a serious investment, you have to understand the basic principles of solar product types. In the manufacture of PV modules, different semiconductor materials are used, but silicon-based batteries are the most demanded on the market. They can be amorphous, monocrystalline, and polycrystalline.


Flexible models made of amorphous silicon work better than others in cloudy weather and in diffused lighting. They have less loss of performance during heating and the most affordable price. Thin-film PV modules can be used as an energy-saving cladding material and integrated directly into the building. Their main disadvantage is low efficiency: no more than 12%.


Monocrystalline and polycrystalline PV modules are made of polysilicon. They have the same design but differ in technical characteristics.

  • Monocrystal models cost on average 7-10% more due to the more expensive manufacturing technology. They have a uniform dark gray or black color; photocells are in the form of pseudo-squares. Efficiency ­ up to 22%.


  • Polycrystalline models consist of square photocells in a non-uniform dark blue color. They are larger than monocrystal modules of the same power. Their efficiency is up to 18%.

Compare the Price and Quality

During the hot season, the temperature can affect the efficiency of panels. In such a situation, it is important to pay attention to the temperature coefficient and give preference to the model with its lower indicator. Polycrystalline panels will be more acceptable. For areas in cooler places, this moment can be ignored. Here are some significant features to consider:

  • Power. The indicators declared by the manufacturer are determined according to the STC test standards, that is, in conditions close to ideal. In reality, the productivity of the modules is lower


  • Tolerance is a possible deviation in power. It is desirable that it is positive.


  • The temperature coefficient is an indicator of the decrease in power as the temperature rises (over 25° C). On average, it is -0.41 ... -0.45% per degree.


  • Lifetime. It has more than 25 years of product quality and has a 5-year manufacturer's warranty.


  • Working temperature. As a rule, it varies between -40 ... + 90 degrees.

Check the Warranty for Solar Panels

Manufacturers typically offer a 25-year performance warranty and a 10-year hardware warranty. Some companies even give up to 15 years of warranty.

Inform How to Connect the Solar Panels



For maximum efficiency of the system, panels should be connected in series to generate a higher voltage.


Using these tips, you can choose high-quality solar panels that will provide efficient and stable operation of an independent solar system..

Great info.  We don't see many solar panels here in East TN.  I am sure they will make their way here soon though.  Hope you have a wonderful day!

I'm seeing solar panels on homes more & more these days. Incentives in my area are making the switch more palatable to homeowners.

Nowadays, there are manny different ways to save Earth’s resources, but I assume that solar panels is one the best ways. Consequently, just try to visit this source where you will have a good opportunity to check its price, size and other essential characteristics. I sincerely hope you will find it useful!
