Why should I choose solar for panels?
With the purchase of solar panels you can significantly reduce your energy bill. In combination with, for example, a heat pump and improved insulation, you could even heat your house completely gas-free. A nice bonus in times when energy prices, and especially gas prices, are rising exponentially. Another big plus of solar panels is that you contribute to a cleaner and liveable world. Solar panels provide a significant reduction in Co2 emissions. The materials used in the panels can, after being on your roof for twenty years, also be reused through recycling. Nice!
The advantages of solar panels are therefore obvious. However, nowadays you almost have to be an expert in the field of solar energy to make an informed choice. That is why we decided to explain a few things.
The purchase of solar panels is a long-term investment. Solar panels are on your roof for an average of twenty to twenty-five years. You will earn back the investment within a few years, depending on your consumption and the number of panels on your roof. However, take into account that existing government-subsidized schemes such as the “salderingsregeling” in the Netherlands can be gradually phased out from 1 January 2023.
Another point to take into account when purchasing a PV system is your expected consumption in the future. For example, if you are planning to purchase an electric car or install air conditioning, these will significantly increase your total energy consumption. In this case, installing additional panels may be a good option.
One total solution versus separate component brands
A complete PV system consists of the solar panels, a mounting system to ensure that the panels are firmly attached to your roof, cabling and an inverter. An inverter is an electronic device that can convert direct current to alternating current. The voltage supplied by a solar panel system is in most cases not immediately suitable for use.
There are more than one hundred different brands of solar panels and inverters. Many installers use an inverter from brand A, combined with solar panels from brand B and cabling from brand C. They therefore use separate components when constructing the PV system. This separate component based approach has a number of drawbacks. For example, the separate components have not been tested for compatibility with each other and therefore do not fit together seamlessly. This could, for example, lead to power losses and unsafe situations.
A total solution is one PV system of which all components are of the same brand. As a result, all parts seamlessly work together and the system is also immediately a lot safer. An additional benefit: a product warranty is also much easier to claim if all parts are from the same brand.
