Buying Guide to Select the Best Solar Panels

Before buying a solar panel, it is worth considering its size. This is because they are usually substantial objects that will have to be mounted outside to transform the sun’s rays into energy.

For this, you will have to take into account the space you have outside. If you have an extensive garden, the problem does not arise, but if you are not so lucky, you will have to mount it on the terrace at home. For this reason, we advise you to take the measurements to avoid unexpected events.

Make sure you put it in an open spot where the sun is shining and that maybe the model is easy to install, so you won’t have to spend any more money on the intervention of a professional technician.

For Home or The Camper?

On the market, there are not only solar panels for the home but also suitable for satisfying more … mobile needs. For example, there are models produced to be used in campers or boats, to have a renewable energy source on your vehicle.

Usually, these models are thin enough to be easily mounted without taking up too much space on the windshield of the car or perhaps in the bow or stern of the boat. They are also light in order not to make the means of transport too heavy and not interfere in driving or navigation.

Solar panels for the best brand’s motorhomes can be powered by a cigarette lighter plug, a very convenient solution that avoids complicated connections.

Hot Water

Given that there are many solar panels on the market for sale, it will be necessary to take into account the use that you will have to make of them: in fact, there are models for the home’s power supply, but also those suitable for the production of hot water.

The latter also has an attached tank and can be used instead of a common boiler or water heater for an ecological and above all economic solution. The price of the panels per se, however, is not contained, so if you want to buy them, you will have to prepare yourself to pay a considerable amount.

If you have a swimming pool, you may be interested in purchasing a solar panel used to increase the water temperature to guarantee you, your friends, and family members a hot tub without having to use electricity.

If you only need hot water to shower after the swimming pool, you need a solar shower. Click here for more information.

How to Use a Solar Panel?

The debate on energy, renewable sources, and pollution is more lively than ever. Many still use traditional methods of energy supply, but many people happily chose to take an important step by deciding to use the sun’s energy to give electricity to the house by mounting a series of solar panels.

Of course, the initial investment is not insignificant. This slows down more than someone, but the money spent, over time, turns into savings, also considering the continuous increases in the bill.

The Operation of The Panels

We believe that understanding how things work is always a useful element in making the final decision. For this reason, we will give a brief explanation of the functioning of solar panels, naturally without going into technicalities. These panels are made up of a series of photovoltaic cells that can convert the energy of photons into electricity.
In essence, a process is generated, which, using sunlight, stimulates the electrons present in the silicon, which the cells are made.

Wanting to be even simpler in our explanation, we add that when a photon hits the cell surface, the energy transfers the electrons present. In jargon, it is said that electrons are excited and therefore flow in the circuit, which generates an electric current. The current produced is continuous, but here an inverter comes into play, which transforms it into alternating current.

Efficiency Is Not Maximum.

It is important to know that the conversion efficiency of a photovoltaic system is not only 100%, but it does not even come close to this value.

Good modules can convert no more than 22% of solar energy into electricity. But it is not over because several factors contribute to lowering this already in itself, not high value, starting from the operating temperature: the heating of the cells negatively affects the efficiency of the modules. Even the dirt accumulated on the surface of the panels has negative effects as they are an obstacle.

It is almost useless to underline how negative shading is for energy production. There is also a minimal incidence in the electrical losses typical of wiring and connectors. Finally, photovoltaic cells progressively lose part of their efficiency over the years.

Therefore they do not produce electricity homogeneously over time. It is also estimated that the average life of the photovoltaic cells is between 20 and 25 years, a period in which there can be a 10 or 12% drop in efficiency compared to the beginning.
