The bright and bright sun is the best
The increase this year seems to be mainly due to a remarkably high yield during the months of May and July. In June, August and September the yield was average. The yield was also remarkably high in February.
It's not that a long and hot summer automatically means that solar panels have above-average performance. Solar panels are happy with the sun, but not necessarily with heat, explained Wim Sinke earlier. As a professor of solar energy (UvA), he is also related to TNO.
The ideal combination for maximum performance is a cold, bright sun. But as the sun shines more often and longer in the summer, this advantage outweighs the disadvantage of heat. "We had a lot more sun this year than a few years ago, and the gains from this light are much higher than the heat," says Sinke.
570 euros a year
It is estimated that there are currently more than 12 million solar panels in the Netherlands. Spread over houses, meadows, etc. The number of households equipped with solar panels has increased sharply in a few years and is now estimated at nearly 700 000, or about 10% of the total number of households.
How do households see such a good solar year in their portfolio? "Normally, a set of ten solar panels is worth about 500 euros a year, and this year it will be about 70 euros more," says Puk van Meegeren, energy consultant at Midway Centraal.
"If you do it more often, longer.If you have such conditions, this will also result in a shorter payback period for investment in panels," Van Meegeren said. "But of course, it is not said that next year will be the same."
Seductive
At present, it is still true that the so-called compensation arrangement makes it more financially attractive to invest in solar panels. As a result, solar panel owners now receive a favorable compensation if they produce more electricity than they need and if electricity is returned to the electricity grid.
But the government thinks the regulations will become too expensive. Minister of Economic Affairs and Climate Wiebes is looking for solutions to address this. New regulations should have started in 2020, but probably no earlier than 2021. The current rules will therefore remain in force for at least two years, even for people who now want to use solar panels.
"The government does not only save money," says Wim Sinke. "If we want a large-scale application, it is good to maximize the use of self-generated electricity, because there is no financial incentive for that now because you recover as much for electricity as for yourself. " [19659003] Wiebes estimates that with the new system, households and businesses that produce green energy themselves can still recover their investment in solar panels in about seven years. We do not know yet how the new regulation will go further.
