Solar panels have become cheaper and cheaper over the years and come in complete sets that are easy to assemble and are particularly suitable for garden owners who do not have their own electricity connection on their plot feature. And finally, solar power is also available for free, if you disregard the one-off investment costs for a photovoltaic system. Everything is correct and on top of that, you basically don't even have to have a roof.

There are now also high-yield, mobile modules that can simply be set up anywhere in the garden and catch even the smallest ray of sunshine. We took a look around at a German manufacturer regarding the prices for small solar systems in order to get an initial indication of the expected costs. Graduated according to output, the complete systems for self-assembly start at just under 1,000 euros (120 watts) and end at approx. 2,000 euros and 2 times 150 watts. Whereby the power requirement of a lawnmower is likely to be much higher, right?
Energy requirement in the allotment garden - how high is it actually?
In order to avoid bad investments, the expected individual daily requirement must first be determined. To do this, the rated power of these electricity consumers is multiplied by their estimated duty cycle, which could look something like this:
| consumer | rated capacity | Duty cycle / day | Consumption / day |
|---|---|---|---|
| Radio set | 15 watts | 4 hours | 60 Wh / day |
| TV | 40 watts | 3 hours | 120 Wh / day |
| Receiver | 40 watts | 3 hours | 120 Wh / day |
| lighting | 10 watts | 5 hours | 50 Wh / day |
| Camping fridge | 50 watts | 6 hours | 300 Wh / day |
| Total: | 165 Wp | 650 Wh / day |
Wp = watt peak (maximum power)
The listed examples of the most common electricity consumers already show that complete independence from other energy sources is exclusive With the help of a photovoltaic system in the garden is basically possible, at least in the variant as a complete set it may be associated with some restrictions should. If you have a coffee machine (approx. 600 watts), computer (around 100 watts) or microwave (approx. 800 watts) would also like to use in the country, is better advised with a professional system, planned together with a specialist. This means that even the robotic lawnmower, which we would like to introduce to you in our last post for this month, will run.
