There’s a lot being said about green energy these days — but what should you really believe? Every week, new “facts” and “fables” pop up. At OptimaSolar, we’re here to set the record straight! This time, we’re diving into solar panels.
FABLE! Solar panels are also called photovoltaic cells — they convert light into electricity. So while bright sunlight boosts performance, solar panels still generate energy even on cloudy days. Output will be lower, of course, but still enough to keep your system profitable.
FABLE! Temperature does affect production. Solar panels perform best at moderate temperatures, ideally between 20 and 25°C. That’s because heat can reduce their efficiency by disrupting electron flow inside the cells. That’s why proper ventilation — especially beneath the panels — is essential.
FACT! There are currently no direct subsidies for solar panels from the Dutch government. However, there are other incentives. For instance, the Stimuleringsfonds Volkshuisvesting offers an Energy Saving Loan that can help finance energy-efficient home upgrades. Plus, private individuals pay no VAT on solar panel systems in the Netherlands. And don’t forget: the net-metering scheme (salderingsregeling) is still in place until 2027, allowing you to offset your solar production against your energy use in darker months.
FABLE! While a south-facing roof yields the most sunlight, east- and west-facing roofs are also very effective. In fact, an east-west setup can help spread your energy production more evenly throughout the day — reducing large peaks that might otherwise be fed back into the grid. This is especially useful if you’re considering a home battery. And if your roof has some shading? Modern technology has solutions for that, too.
FACT! Solar panels reduce your monthly energy costs and improve your home’s energy label — often by one or more levels. This generally increases the value of your home. The effect depends on how many panels you install and how much energy they produce.

The electricity grid in the Netherlands is increasingly under pressure. In some regions, the grid is even so congested that new connections are no longer possible. As a result, Enexis is asking households to temporarily curtail…
The end of the net metering scheme is getting closer, and many questions are arising. What happens to solar panels after net metering ends? Are solar panels still profitable once the scheme is gone? From January…
