This page answers common questions about solar systems, including types of panels, insurance options, installation time, and maintenance requirements.
What are the different types of solar panels?
There are several types of photovoltaic panels: mono silicon, polysilicon, PERC, and prascovites. Kedma Solar works with four official importers in Israel who import panels from various companies, including Longi, JA Solar, Jinko, Sunpower QCell, and Eging. All these companies are ranked Tier 1 by Bloomberg and are recognized as high-quality brands.
What insurance options are available for solar systems?
Yes, solar systems can be insured. Insurance companies offer coverage for solar systems as part of supplementary insurance, which includes protection against fracture damage, weather-related issues, and loss of income during repairs.
Is there a risk of radiation from a solar system?
Solar panels are passive components and do not emit radiation. The voltage converter produces minimal radiation that meets all safety standards, posing no real danger as it is installed outside the house.
Is there a warranty on solar systems?
Most leading manufacturers provide a 25-year warranty for the performance of solar panels, which are expected to operate for decades. The warranty on the converter is typically 12 years, with an option to extend it to 25 years.
What does the maintenance of a solar system require?
Regular maintenance of a solar system mainly involves washing and cleaning the panels from dirt. It is recommended to wash the panels about 3-4 times a year.
How does a solar system convert sunlight into electricity?
A solar system converts sunlight into electricity using solar panels made from photovoltaic cells and a voltage converter that connects to the power grid through your home electrical panel.
How does a solar system work in winter?
The system continues to produce electricity during the day, although its production capacity varies by season. It produces less electricity in winter than in summer. However, since the system is designed based on average annual daylight hours, this seasonal variation is accounted for, allowing for surplus production in summer to offset lower production on rainy or gray days.
Who is a solar system suitable for?
A solar system is suitable for any property owner with a free roof who wants to utilize it for solar energy generation.
How long does it take to install a solar system?
The actual installation of a solar system takes a few days. However, the entire process, from the decision to connect the system to the electricity grid, can take about 3 months due to the need for various approvals.
Is investing in a solar system profitable?
Home solar systems yield returns of 12-18%, while commercial systems can reach 24%. The investment can be recouped in about 7 years for a home system and about 5 years for a commercial system. Solar systems are designed to last for 25 years with a decrease of less than 0.5% per year, making them a wise investment for households seeking stable financial returns.
Are there options for financing a solar system?
Yes, there are dedicated programs for solar electricity offered by central banks, providing up to 100% financing for up to 10 years at an interest rate of prime + 1.5%. Some clients have even received rates of prime interest minus 0.5%!
What permits should be issued to install a solar system?
To obtain a permit for installing a solar system, several permits are required, including an electrical plan, constructor’s permit, electrical engineer’s permit, coordination with the electricity company, and registration with the Ministry of Energy. Kedma Solar will handle the entire licensing process and all necessary documentation for you.
