Interest in photovoltaic self-consumption has increased exponentially in recent months. Proof of this is the number of emails and calls, both from companies and individuals, that we are receiving at Solar Panel to request a feasibility study ( technical and economic report ) on the installation of solar roofs.

And it is that solar energy is not a matter of fashion. Society is increasingly aware of the fight against climate change, opting for photovoltaic self-consumption as a clean and economical energy alternative.

One of the decisive issues when designing an energy self-consumption project is the choice of the solar panel.

The solar panel is the main component in photovoltaic installation consumption since they are responsible for absorbing sunlight and convert it into electrical energy.

Type of photovoltaic solar panel

The most common photovoltaic solar panel on the market is made up of monocrystalline or polycrystalline solar cells. Both are made of silicon, which is an abundant, resistant, and long-lasting mineral, and the main difference between them is the purity of the silicon. The more perfect the crystal structure, the fewer impurities the panel will have and, therefore, its performance will be higher.


The availability of space to mount a solar cover and its location are key when choosing between a monocrystalline or polycrystalline solar panel.


passive diactric between the aluminum layer and the silicon base layer of the cell, so these infrared light electrons do not penetrate to the aluminum layer and are reflected, allowing current to be generated between the base layer and the emitter. This use of infrared light gives the PERC cell greater “sensitivity” too long wavelengths.


Solar panels composed of polycrystalline cells have a long history in the photovoltaic sector. They are made up of cells whose silicon does not come from a single crystal but from many small group melts. This makes it not as pure as a monocrystalline cell so its efficiency and performance are somewhat lower than a monocrystalline panel. Its greatest advantage is its cost and the shortest manufacturing time.

Maintenance of solar panel

The maintenance of the photovoltaic panels is essential to ensure their proper operation and guarantee the longest useful life of the installation.

Photovoltaic solar installations are subject to external agents and temperature changes that affect both the panels and the electrical connections that make them up. Maintenance operations depend on factors such as the technical characteristics of each facility, weather conditions, or existing environmental contamination in the area in which it is located.

In most cases, solar panels are cleaned directly by the rain. However, in areas with a lot of wind, high pollution, dust, and dirt, production can decrease by up to 15% over the life of the solar panel installation. To mitigate this effect, it is necessary to clean the solar panels once or twice a year.

Solar Power Saves You Money

The average Australian household could save an incredible 80% on their electricity bills if they installed solar panels. We hope to cut all Australian electricity bills down to nothing, so we offer competitively priced solar power solutions to families in Newcastle. Our payment plans start at just $20 per week, with a $0 deposit and no interest – ever.
