We have compiled for you the most frequently asked questions about solar systems
How does a solar system work?
A solar system converts the light radiation created from the sun's energy into electricity with the help of solar panels built from photo-voltaic cells, and with the help of a voltage converter that connects to the power grid through your home electrical panel.
Who is a solar system suitable for?
A solar system is suitable for any property owner with a free roof who wants to use it for the benefit of a solar system.
How long does it take to install a solar system?
The actual installation of a solar system takes a few days. The entire process, from the moment of the decision to the connection of the system to the electricity grid, takes about 3 months in order to obtain the relevant approvals from the various parties.
Is investing in a solar system profitable?
Home solar systems reach a yield of 12-18% and commercial systems can reach 24%. Return the investment in about 7 years for a home system and about 5 years for a commercial system. The systems last for 25 years if there is a decrease of less than 0.5% per year. Therefore, a solar system is not only profitable, but a wise investment for young couples, retirees, foundations and any household that wants a stable and profitable financial investment for 25 years.
Are there options for financing a solar system?
Today there are dedicated programs for solar electricity in the major banks. The banks offer up to 100% financing, up to 10 years, with an interest rate of prime + 1.5%. (We have clients who even received prime interest minus 0.5%!)
What permits should be issued in order to install a solar system?
In order to get a permit to install a solar system, a number of permits are needed (electrical plan, constructor's permit, electrical engineer's permit, coordination with the electricity company, registration with the Ministry of Energy, and more...) but don't worry, we will take care of the entire licensing process for you and take care of all the documents needed!
How does a solar system work in winter?
The system works and produces electricity during the day (and sleeps at night). The production capacity varies from day to day and from season to season, with the system producing less in winter than in summer. But since the planning of the system is carried out according to the average annual daylight hours - this has no meaning. In practice, in the summer the solar system will produce surpluses that will
To your credit on the rainy and gray days.
What does the maintenance of a solar system require?
Regular maintenance of a solar system mainly includes washing and cleaning the panels from dirt. The recommendation is about 3-4 times a year to wash the panels.
Is there a warranty on solar systems?
Most of the leading manufacturers provide a 25-year warranty for the performance of the solar panels (the panels are expected to operate for decades)
The warranty on the converter is 12 years, with an option to extend it to 25 years.
Is there a risk of radiation from a solar system?
The solar panels are passive components, therefore there is no radiation, the voltage converter of the system produces a little radiation that meets all standards, but there is no real danger in it and it is installed outside the house.
Is there insurance for a solar system?
of course! Solar systems can be insured. Today, insurance companies offer insurance coverage for solar systems as part of supplementary insurance. The insurance coverage includes fracture damage, weather and insurance against loss of income in case of need for repair.
What are the different types of solar panels?
There are a number of different types of photovoltaic panels - monosilicon, polysilicon, PERC, and even prascovites. You can read about the technical side of each type of panel in the links above. We work with four official importers in Israel who import panels from different companies. Among them: Longi, JA Solar, Jinko, Sunpower QCell, Eging, etc.. All the companies are ranked Tier 1 by Bloomberg and among the most recognized and high-quality brands in the world.
