What is net metering? Why is the scheme being phased out and what will replace it?

How big are solar panels, and how many fit on my roof? The size of a panel says a lot about its output and about how many will fit. We also choose A-grade brands with solid warranties. This blog covers the dimensions of solar panels and how to make the most of your roof.
The size of the solar panels from Dijkman Zonne-energie
If you choose solar panels from Dijkman Zonne-energie, a panel measures about 114 cm by 176 cm. Which type our adviser recommends depends on your situation. Our advisers look at the size of the roof on the spot, at the obstacles to work around and at which panel gets the most out of your roof.
Making the most of your roof with the right panel size
To get the most out of the space on your roof, the size of the panels matters. Our advisers map your roof to see how the panels are best positioned for the highest yield, so you know every square metre is put to use.
A roof cannot always be filled completely. Obstacles such as vent pipes or a boiler flue can get in the way. The weight of the panels matters too: the roof has to be in good condition so they can rest there safely, with no risk of collapse. There is also the so-called no-go zone, which means panels may not be laid right at the edge of a roof, in case the wind gets under them. On a sloping roof they stay about 20 cm from the edge. On a flat roof it depends on the height of the panels.
The size of a panel decides its output
The bigger the panel, the more power it produces. A Longi panel of 103.8 x 175.5 cm is rated at 365 to 370 Wp, while a Hyundai panel of 114 x 171.9 cm is rated at 400 Wp. The larger surface catches more sunlight and turns more of it into electricity.
How the panels are laid out
The size of the panels also affects the layout. On a flat roof they have to be set at the right angle so they do not shade each other. On a sloping roof our advisers take the obstacles and the orientation into account. That tells them how many panels you need to cover your consumption.
How many solar panels do I need?
How many panels you need to cover your whole consumption depends among other things on the type of panel and on how many fit on your roof. Want to know more? Read our blog "How many solar panels do I need?".
Little difference in quality between panels
These days the difference in quality between the brands is small. Solar panels have been on the market for a while, but they are still being improved: the quality keeps rising and the design keeps getting sleeker. Where roofs carried blue panels a few years ago, they are black now, which looks more modern.
