Solar system, solar panels and solar panels - are concepts that everyone is familiar with today. But where did it all start? And how does it even work? - All the answers in the next article
The photovoltaic effect on which the technology that operates a solar system consisting of segments of solar panels, also called solar panels, is based, was first discovered in 1839, and half a century later the first photovoltaic cell was built. It would be almost another century until three American researchers invented a solar cell with a 6% efficiency in direct sunlight. From here, the road was short until the world powers learned to use sunlight to produce energy available for daily use - first to heat water, and then to operate lighthouses, trains and satellites.
At the end of the last century there was a leap forward in the industrial use of energy produced from fields of solar panels. Since then, we have witnessed impressive progress in the technology used to produce solar energy, both in the commercial market and in the home market, through the installation of a solar system on the roofs of buildings, agricultural fields, and more. In 2020, the Israeli government announced a revolutionary target for electricity production from renewable energies - which will be 30% of total electricity production by 2030, and encourages its achievement through various arrangements and benefits.
Energy production using solar panels - this is how it works
A solar system converts the sun's energy into electrical energy, using Solar panels Built from a metal frame and inside it a layer of silicon cells, a glass shell and suitable wiring that allows flow. The interaction between the sunlight and the silicon cells creates a direct electric current, which is captured by the wiring nodes on the board. The glass shell, which characterizes many solar panels, protects the silicon cells and the wires between them. The insulation layer under the glass prevents the dispersion of heat and moisture inside the panels and maintains their efficiency. Using a dedicated electric converter, the system converts the direct current into alternating current, which flows according to the voltage of the national electricity grid and is ready for immediate use both for the manufacturer itself and as a product sold to the electricity company.
Where can a solar system be installed?
Installation of Solar system It can be performed on flat roofs as well as tiled roofs - and in fact on any roof that has maximum exposure to direct sunlight, but significant commercial savings can only be created on a roof area of 300 square meters or more. The roof environment is also significant, so it is important to be careful that it will not be overshadowed by buildings or other factors in the environment. It is advisable to take care of the roof area and remove branches that may leave scratched solar panels, and locate places where strong wind may cause damage to the panels. To maintain an efficient solar system, it is important to choose the location of the panels and the optimal angle for efficient absorption of sunlight. If possible, solar panels will be installed facing south - where the radiation is stronger.
solar panels They are a business for experts
In order to install solar panels on the roof and establish a profitable solar system that will generate a significant passive profit for its owner, it is necessary to choose the appropriate system and install it accurately and professionally, with the help of the most modern equipment available on the market today. Shahar Energy is one of the oldest companies in the solar market in Israel and has extensive professional experience and talented and skilled staff members. The high level of reliability of the company, which has already installed solar panels on commercial roofs in hundreds of projects in Israel from Dan to Eilat, is among the highest in the market. The company has several worthwhile profit paths and a 25-year warranty on all systems. Without a doubt - a solar system is a business for experts!
