not much snow in Romania in winter?[sorry for asking, buy i never been in Romania "in person"]
if so, update solar panels with cleaning machinery and/or use snow-proof installation[cost some power efficiency, usually].
or try diversify power supply between TYPES of generation, like add few vertical wind turbines or even build geothermal power station[thats more expensive, but have longer TTL].
It's similar to Chicago in weather, if you live in the USA. I intend to use a steel mesh net to protect against large diameter hale (very rare, but very large), and for snow I have to either wait for the sun to shine long enough to melt the snow (remember that the cells absorb photon energy, even visible rays have a heating effect) or use a flipping mount which can rotate to dust off the snow from time to time. As explained in the first post, wind turbines are needed since they're cheap and low maintenance and I have plenty of space to plant them.
I know there will be extremes (like cloudy snowy but calm winter days and very bright and windy summer days) and I can only hope to level those off with some batteries, emergency grid hopping or even using a petrol generator in case of black-outs. I don't know yet if it's more important to run at higher capacity and shut down when out of power, or gradually reduce usage to have uninterrupted uptime.
