Photovoltaic systems are the way to take advantage of solar energy and bring 3 great returns to your home or business: reduction of up to 95% in the light bill for more than 25 years, protection against energy inflation, and property valuation.
As all of us have noticed, each year it becomes more expensive the price of electricity in the World. According to the Institute for Energy Research, the average price of electricity has increased by 67% comparing 2014 to 2000.
End consumers and companies are becoming tired of this escalated prices.However, nowadays we can generate own energy through solar panels that capture and convert sunlight into electricity.
Photovoltaic solar systems, as they are known, have won the hearts of enterprises and end consumers, because they can save up to 95% on the electricity bill and also enjoy other benefits. Get to know below how to use solar energy to reduce your electricity bill.
Heliothermic Solar Energy
The first big difference of this technology for the photovoltaic is that heliothermic is not the light itself that generates energy.
Besides requiring a lot of space for its use, limiting its use in large projects, it works like this: large reflector mirrors are built around a large central tower, capturing and converting sunlight to a receiver installed in the tower.
The heat received will be transferred to heat a reservoir filled with a special liquid which, when heated, will vaporize and power an electric turbine, generating energy.
Photovoltaic Solar Energy
Photovoltaic solar energy converts direct sunlight into electrical energy.
The photovoltaic effect was discovered by the French physicist Alexandre Edmond Becquerel in 1839 when he observed that some materials, mainly metallic, emitted electrons from their surface to contact with certain intensities of light.
This electron emission is the basis for the operation of solar photovoltaic technology. A solar panel, or photovoltaic module, is composed of several photovoltaic cells made of semiconductor material, with Silicon being the most common of them.
This semiconductor, however, undergoes an artificial modification process, called doping, which creates two distinct layers: one negative and one positive, that is, one with excess electrons and another with the absence of them.
The two layers are then joined, with the negative being over and the positive underneath. When in contact with sunlight, the negative layer releases electrons that migrate to the positive layer through an external bond, forming an electric current.
The sum of the electric current of all the cells forms the total power that a solar plate can deliver, which varies between 275 to 335 Watts in the modules currently commercialized.
But to achieve this, you will need more equipment than the boards, which together form solar photovoltaic systems.
Photovoltaic Systems For Electrical Generation
Just like a traditional diesel generator, the function of a solar photovoltaic system is to generate electricity but using sunlight, a clean and abundant source.
The produced Electric power, if it is not consumed, should be drained or stored in batteries.
With this concept in mind, the first thing you need to know is that there are two types of systems: On-grid and Off-Grid.
The two generate energy in the same way, through the solar plates, the only difference is the way the energy generated and not consumed will be treated.
In systems connected to the grid, the street pole receives the load, flowing to the distribution line of the distributor, whereas in isolated systems it is stored in a bank of batteries.
There are many advantages that it brings to you, the main ones being:
- Saving up to 95% on the light bill;
- Protection against energy inflation;
- Plates with a lifespan of more than 25 years and with an efficiency of at least 80% of generation;
- Valorization of the property;
- 100% silent generation.
