Solar pv systems will bring some electromagnetic pollution

Since those early days of Photovoltaic solar power much has been achieved, but in a global perspective, it is far from enough. The boundless energy waste has still not changed. With a little more energy consciousness and even more effective devices, we could easily save half the electricity we use.

Technically, it should be possible to live 100% on solar power if we were to reduce our electricity consumption a bit. Solar systems are becoming part of the modern landscape but even so the potential of solar energy is greatly underestimated. Solar systems give us the possibility of setting up an independent power supply without causing any disturbing alternating electromagnetic fields. With solar energy we can enjoy the luxury and benefits of electricity, while not being forced to live in a permanent electrosmog field.

Although solar panels and batteries in off grid systems generate a clean direct current. The situation is quite different with modern solar controllers, 230Volt inverters and the inverters for feeding the grid. These are the ones, which can turn a basically very harmless technology into a bad electrosmog polluter. There are technical ways to do it differently and I think the entire direction of solar development really needs to be rethought.

The latest rage in solar charge controllers are called MPPT-Solar-Controllers , which have a voltage converter that works between 20 and 30kHz. Their advantage is that they can generate the optimum ratio of current and voltage to charge a battery from any input voltage. But no one mentions the major disadvantage, that this type of controller is a really potent electrosmog polluter, happily humming all day to itself. The interference fields are often comparable with those of small transformer stations! Well meant, but unfortunately the very opposite of well done.

Inverters fall into the same category of electrosmog polluters. Unfortunately, they are often unavoidable unless you are able to source or rebuild all your appliances to be 12 volt, which have lower electrosmog and converting losses. The less we have to turn on the inverter the better, because our bodies respond better to short electrosmog attacks than to continuous 24-hour stress. The interference from pv inverter is very strong because of the large currents between battery and the inverter. Low-cost devices are the worst with high-frequencies (20–30KHz) generated on top of the trapezoid waves, which causes a lot of more interference.

In terms of electrosmog the disadvantages of MPPT controllers and 230 volt inverters are combined with grid inverters, as they always make a lot of wave motions in the ether. The interference frequencies of these inverters often also bleed over into the DC circuit of the solar panels on the roof. The electrosmog is then potentially very strong because of the large size of the installations. Capacitors or mains filters can buffer the harmful electromagnetic waves but not eliminate them entirely. This problem could really only be corrected by creating a decentralized DC network, but this is something that is still a long way off.
