Learn How to Optimize Your Home Solar System
Sela Infrastructures LTD — specialists in installing, operating and maintaining solar energy systems — explain how a comprehensive tailor-made solar energy production system will yield maximum energy efficiently, precisely and simply
The global energy economy is undergoing a major change. The climate crisis and the urgency of carbon neutrality and energy security dictate a rebuilding of the energy economy everywhere — phasing out oil, coal and natural gas, and replacing these fossil fuels from green and renewable energy sources. Alternative energies will, it is believed, not only rescue our planet but also spur efficiency and economic profit. Key among these important alternatives is the harnessing of our sun's energy. In Israel, solar energy systems have long been widely used countrywide — in commercial and private buildings, water sources, and industry and agriculture.
A cornerstone of smart utilization of solar energy is vigilant, ongoing maintenance of the solar collection site. Solar panel efficiency and output increase significantly when panels are clean and well maintained, and problems are rapidly identified and solved. Sela Infrastructures Ltd. has been building and maintaining solar systems for the past 12 years and is passionate about solar energy and its power to transform the world. The company is in tune with both the growing demand for alternative energy, and the challenges on the ground that this brings. Its professional teams are familiar with the range of solar technologies in use in Israel and worldwide, and, constantly ahead of the curve, they use what is most appropriate for the systems they build, operate and maintain for their many clients.
Full maintenance
Created as an external contractor for solar systems, Sela Infrastructures has grown into an independent company capable of providing solutions for all aspects of solar energy. In each of the thousands of solar energy systems it has deployed throughout Israel, its guiding principle has always been and remains provision of a comprehensive system, from planning through construction to ongoing maintenance. In practice, this means that the company not only installs the solar system, but also helps its clients through the Israel Electric Corporation's licensing process and the integration of their new energy system into the national power grid, along with the necessary infrastructure and meterage.
Installation of the system is far from the end of Sela Infrastructures involvement. The company operates a branch which monitors and controls the package, responding to client needs and frequently handling issues that may arise with the Electric Corporation. It also takes responsibility for much of the system's ongoing maintenance: washing the solar panels, checking for problems, replacing faulty panels and comprehensive inverter testing, which includes wiring and the services of an onsite electrician.
Maintaining productivity
The importance of maintaining solar systems is rooted in the technology that produces energy from the sun's rays. Dust and debris on solar panels reduce their exposure to the sun, which reduces their efficiency by up to 35 percent — so washing panels is key in routine maintenance of solar energy systems. Those serving households are washed at least four times a year, with commercial systems requiring more frequent washing.
Tap water, with its mineral deposits, leaves residue which makes it unsuitable for cleaning solar panels, and today's market offers a long list of solar-panel washing and cleaning solutions. These range from simple techniques based on manual washing to advanced digital approaches which wash automatically on a predetermined schedule. (Sela Infrastructures notes that while automatic washing systems are very efficient, occasional manual cleaning is also advisable).
The cleaning material aside, Sela Infrastructures points out that a major challenge in washing solar panels lies in their location: most are not readily accessible, placed as they are on rooftops, vast fields or over water sources, and reaching them is the job of qualified, experienced personnel.
Monitoring and controlling solutions
Solar energy systems are generally considered extremely durable. Most of those on the market carry a 25-year warranty and even inverters are guaranteed for 12 years or more — clear evidence of their manufacturers' faith in their producing reliable energy over time. Vital in maintaining their efficiency are built-in monitoring and control technology, which sounds alerts to problems, from a tripped circuit-breaker to voltage or communications faults. Advanced monitors will warn of reduced output in a solar panel. This technology is supported by annual inspections from technicians and electricians. This is the responsibility of the solar energy producer.
Long lifespan
Bottom line, the maintenance requirements of solar systems are minimal, which is an important factor in the economic feasibility solar energy production, and the decision to make the transition. Those making this decision will do well to look to Sela Infrastructures. The company provides all necessary maintenance for solar systems, along with a variety of services and products, customized to the needs of each client. From washing solar panels, through monitoring and control, to repairs, Sela Infrastructure's professional package gives solar system operators the full economic benefit of producing energy directly from the sun while entrusting all maintenance to safe and experienced hands.
