Choosing solar panels for your home has two advantages: it saves you on your bill; is good for the environment . The sun is in fact a source of energy that is always available, which never runs out and does not pollute. Solar energy is therefore a choice of conscience, rather than practice. We are sure it is always feasible, but
In recent years, many types of solar panels for the home have appeared on the market , some of which are even portable. They are easy to assemble and the production price drops from year to year as they become more popular. So you just have to read the article and find out which models are best for you, your home, your needs. Types of solar panels for your home
The term ” solar panels ” encompasses at least three main types of products, with different characteristics and functions. They are almost all equipped with a glass panel that protects the structure and collects the sun’s rays. The rays are conveyed in a circuit that changes according to the type of panel, transforming them into thermal or electrical energy. Solar panels for hot water
Thermal solar panels are the classic solar panels for hot water. They are the most basic models and you can use them for both domestic hot water and heating. In this second case, the water heated by the circuit passes through the pipes instead of that heated by the boiler. In this way you save gas without sacrificing your thermal comfort.
Thermal panels can be with or without glass . Under the glass there are modules consisting of a plate of material with high thermal transmittance, usually steel or copper. Under the plate are bundles of pipes filled with a mixture of water and antifreeze, which heats up with the sun’s heat. The hot liquid transfers the thermal energy stored in a tank, to use it now or later. Depending on the model, the transfer can be natural or forced.
Solar panels for hot water are the cheapest, especially when they have no glass. The absence of glass makes them more efficient immediately, but also more subject to deterioration. Glazed models are a little less efficient at first, but are more durable and cost effective in the long run. Photovoltaic panels
The most classic solar panels for home are photovoltaics , ie those that can be used to produce electricity. However, they are less efficient than solar panels for hot water and more expensive. The thermal panels have aefficiency of about 80%, while photovoltaics by 17% . Furthermore, each house requires a large number of devices, if you want to achieve complete energy autonomy.
Each panel is made up of many modules made of treated silicon . When photons from the sun’s rays strike silicon, its electrons generate an electric field. The larger the surface hit by the sun, the more energy is generated. At this point the electrical terminations below take the energy and transform it into electricity . Unfortunately, a large part of the energy is lost in this second phase. But scientists are working on more efficient alternatives.Thermodynamic panels
The thermodynamic panels convey the advantages of the thermal and photovoltaic ones. You can use them both as solar panels for hot water and to produce electricity . In addition, they are much more efficient than photovoltaics and are in fact becoming increasingly popular.
The premises are similar to those of thermal models, i.e. exploiting the heat produced by the sun’s rays . However, the mechanism is much more complex:

  • the panels convey the sun’s rays into a special heat-carrying liquid;
  • the liquid passes from the liquid to the gaseous state;
  • the compressor compresses the gas, which transmits the heat to the water contained in a tank;
  • the cycle starts again.

The heat produced can also be used to generate mechanical energy , which in turn generates electrical energy . Among the different solar panels for the home, they are certainly the most complete. Do-it-yourself solar panels: it’s possible Solar panels and do-it-yourself are two compatible things or it’s pure science fiction
If you plan to install a solar power system in your home, you can do some of it yourself. You can manage some stages of the installation , reducing the need for external labor and expenses. Here is a list of the things that you must mandatorily delegate:

  • network connection of the photovoltaic system;
  • project;
  • installation authorizations;
  • connections to systems.

What can you do with DIY solar panels , then
You can buy solar panels for your home , the materials needed for installation and supporting structures. In some cases, you can even mount the panels starting from individual cells : online I find numerous kits designed for this purpose. Attention, however: the electrical connections between the different cells must be carried out by an electrician. The actual installation must also be left to competent personnel.
If you are looking for less complex solutions, you can orient yourself on DIY solar thermal panels . In this case, sheet metal , glass wool and a coil are usedto produce a rudimentary plant. Obviously, the efficiency is not comparable to that of traditional solar panels for hot water. The compromise: portable solar panels for home
Portable solar panels for home are a compromise between classic systems and DIY. Usually the panels are fixed to the roof of the house, with all the consequences that this entails. You must have them connected to the systems and you must ask for specific authorizations from the reference municipality. From this point of view, the portable models are much more comfortable.
Since they do not require connections and should not be installed, you don’t have to worry about municipal permissions. If you have a sunny terrace or a nice garden, just choose the brightest corner and place your panel there. The electricity is collected in a battery included in the kit , to be attached to the appliances you want to power.
As convenient as they are, portable solar panels for the home do not replace the normal electrical system. Rather, you can use them for the daily use of household appliances such as computers and televisions. In this way you lighten your bill and avoid system overloads, common in summer due to fans and air conditioners always on. Solar panels for home are worthwhile
Although the price has come down a lot in recent years, solar panels for hot water and electricity are a big expense. So you may be wondering if such an investment pays off and how long it takes to get it back. The answer is yes: despite the initial costs and maintenance costs, solar energy is worthwhile .
The prices of solar panels vary according to the type of system and the size of the house. It ranges from a minimum of 2000 euros up to 10,000 euros for very large houses. This is a huge expense, which you can recover in part thanks to eco -incentives and bonuseson renovations. Thanks to the latter, about half of what you spent over 10 years could come back in your pocket.
The real convenience of solar panels for the home lies in what you save. With the right square footage, you can become almost completely energy independent . Thermal panels alone can save you hundreds of euros in heating every year, paying for themselves in a few winters. In the long run, a real bargain.
