On the roof of J. Nainis – a 15 kW solar power plant: it has been revealed how much energy it consumes per year

Lithuanian television and radio host, music producer Jonas Nainys and his wife Simona also decided to produce their own electricity. He reveals the reasons that pushed them to install a solar power plant and how much electricity his smart home consumes per year.

As for what prompted the installation of the solar power plant, J. Nainys does not hide that one of the most important reasons is economy.

“Before installing a solar power plant, you have to fulfill the ESO requirements, so doing this was a great opportunity to assess how much electricity I consume in a year. I never counted this, although our house can be called semi-smart – it has many different electrical devices, a system has been installed so that the electricity turns on by itself, many things can be controlled by phone. It turns out that we consume even about 10 thousand per year. kWh. This is a lot,” the music producer shares, adding that it is estimated that the investment in the solar power plant should pay for itself in just a few years.

He reveals that the idea of ​​having “our own” electricity had been on his mind for some time, and sustainability and the desire to be independent were no less significant incentives. “Even though we live in a brand new neighborhood, we’re seeing more and more neighbors opting for sustainable energy.” I think that it is not too late for us to jump on the train of installing solar power plants. New technologies are coming to the world and I believe that such solutions are our future”, J. Nainys thinks.

“Knowledge is needed to deal with all ESO matters, so for an ordinary person, it seems that his head will explode. Our solar power plant contractor “Energija futura” helped to solve these seemingly complicated works in just a few minutes”, shares J. Nainys. He adds that it was also difficult to understand how the entire system works, but the experts explained that as well.

Energia futura’s solar power plant installer Dovydas Ivanauskas said that, taking into account the electricity needs and the roof’s capabilities, it was chosen to install 33 solar modules, one of which has a power of 445 W, on the roof of J. Nainis’ house. Thus, a total of approx. 15 kW power plant.

D. Ivanauskas explains that since the direction of the roof is not ideally oriented towards the south, in order to achieve greater electricity generation, as many modules as possible were installed.

“For this, we chose the optimized SolarEdge system, which allows the installation of modules on more than two different roof slopes. This system ensures the most efficient generation on the market and allows even the most complex roofs to be properly employed. The modules, with the help of the system, work independently of each other and do not interfere with each other’s work, so we can squeeze the maximum benefit from them, thus providing Jon with the maximum amount of electricity generation”, the specialist presents the solution and adds that in the future, if necessary, the power plant will be able to be expanded when installing additional modules, which can be of different power and even different manufacturers.

He continues that the power plant was installed on a tiled roof, which requires special care: “Since the tile is a fragile thing, the power plant must be installed with quality and responsibility so that the tiles do not split or break over time, so that water does not start to run through the roof.”

“The high-voltage cables of the solar power plant are installed under the tiles, next to the wooden structures, and although it may not seem very safe, it is the optimized system of SolarEdge that allows us to achieve maximum safety. In the event of any unwanted event, any roof accident, the system switches off automatically and ensures a low and safe voltage in the wires, thus ensuring protection against the occurrence of an electric arc and fire and, most importantly, protecting health and property”, explains D. Ivanauskas.

He adds that rooftop optimizers with integrated temperature sensors that continuously monitor module junction temperatures and react to any deviations from nominal operating temperatures also help to ensure additional safety.

“Exactly the module connections are the weakest part of the solar plant, which is responsible for more than 70 percent of the of all faults. The optimized system, having detected an anomaly, shuts down and sends a message to the installer. A single solution cannot provide comprehensive security, so a solar power plant needs several levels of security layers that complement each other, thus eliminating even the smallest risks,” notes the solar power plant expert.

In addition, today’s optimized solar plants allow you to monitor the operation of the modules in the SolarEdge mobile app on your smartphone, so when you connect to the monitoring system, you can see the generation of both the solar plant and the individual cells.

“In the case of John’s power plant, in the future, if necessary, it will be possible to connect storage batteries to the existing system, which are useful for even better management of your home’s electricity consumption and further reduction of electricity bills,” notes the power plant installer and claims that the inverter provides 12 years, and for the optimizers – a 25-year guarantee, the performer will enjoy the efficient operation of this power plant for a long time.
