Being off grid is a fairly broad term that encompasses many things. It could mean being completely disconnected from anything: you generate all your electricity, sewage, food, and heating needs yourself. But it also means using clean energy solutions to power your own home whether you’re connected to a local electrical grid or not. So if you want to generate your own power, what are your options?
The most well-known and accessible option is putting solar panels on the roof of your home. Nowadays it’s pretty straightforward and you can also use solar trackers for added energy generating efficiency to get that extra bit of sun. With solar trackers, your panels move along with the sun to ensure maximum exposure. Every year, there are new technological breakthroughs as solar cells become more efficient and costs drop. They’ve even figured out how to make solar panels nearly invisible if you’ve got a problem with how it looks.
Wind energy is energy generated by the flow of air. You’ve probably seen the giant wind turbines dotting the landscape in various parts of the world. While it might seem that buying wind energy is your only solution, there are small-scale wind power setups available if it is appropriate for where you live.
Micro hydro is a type of hydroelectric power. Unlike hydroeletric power which uses large infrastructure such as dams and reservoirs and can harm the local ecosystem, micro hydro power is all about keeping it on a small scale by using a minimal and natural flow of water. The power generated from micro hydro installations produce anywhere from 5 kW to 100 kW. To give you an idea of how much that is, a 100 kW can power a home or a small business. These kinds of systems often complement solar systems making up for the shortfall of sun during the winter.
Geothermal energy is using thermal energy from the Earth to make power. While it’s possible that there is enough geothermal energy to power the entire world, the energy isn’t available everywhere and exploiting hard to access geothermal energy is cost prohibitive. Smaller scale geothermal power plants are increasing in popularity but these are still industrial level solutions. If you’re looking for a geothermal solution for your home, check out a geothermal heat pump which transfers heat to or from the ground to manage your home heating and cooling needs. Upfront costs are high but with subsidies and the amount of money you’ll be saving on your heating and cooling bill, the system should pay itself back in a few years.
So what if you can’t put solar panels on your home or set up a wind turbine or generate your own micro hydro or geothermal energy? Switch to an energy provider that provides clean energy. Go out there and do your research. There are energy providers who produce clean and renewable energy. So even if you you might not be able to generate your own clean energy any time soon and be completely off grid, at least you can support the energy you would like to generate.

Austria''s largest open-air photovoltaic plant recently went into operation in Schönkirchen-Reyersdorf. It is designed to supply clean solar power for forty years. This requires exceptionally robust components, including those used in the electrical connection systems. These come from LAPP.
Austria has set itself ambitious climate targets. In particular, the photovoltaics sector is to be massively expanded. To meet the requirements with typical small-scale installations for single family homes with an output of five kilowatts, around 750 systems would have to be constructed – every day until 2030. However, there''s no need to worry about running out of roof space at some stage because in Austria, the trend is towards large installations with an output of several megawatts.
The country''s largest outdoor photovoltaic system was opened in November 2020 in Schönkirchen-Reyersdorf, north east of Vienna. The 34,600 modules cover an area of 13.3 hectares, which is approximately 18 football fields. Together, they generate 11.5 megawatts, a total of almost 11 gigawatt hours of electrical energy per year, corresponding to the consumption of 3,400 households. This saves 8,000 tons of carbon dioxide per year. The next stage of the project will be a further 10,400 modules providing 3.5 megawatts and supplying 1,000 more households with green energy. The costs are split equally between the energy companies OMV and VERBUND, with KPV Solar having overall responsibility for constructing the installation.
The market for photovoltaics in Austria is growing by 50 percent each year. LAPP is benefiting from this. The global market leader for integrated cable and connection technology solutions is one of the leading suppliers for photovoltaics in Austria and is seeing strong growth in sales. "Brands such as ÖLFLEX® are very well known here and are in high demand", says Andreas Felber, sales engineer and the person responsible for photovoltaics at LAPP Austria.
A major advantage for LAPP is its superior logistics. For the project in Schönkirchen-Reyersdorf, KPV Solar created a quantity structure as part of their planning as a basis for its orders from LAPP. LAPP ensures that the specified goods are in stock at LAPP Austria in Linz, and the customer can then call them off as required. KPV Solar always gives a week''s notice of the day on which they need the goods and LAPP delivers them to the site on that exact day.
In order for such projects to really pay off in the end, despite tight calculations, the connection systems need to last for as long as the solar modules, i.e. as close as possible to 40 years. Since LAPP’s connection systems meet this requirement, they are often the first choice in the solar industry. LAPP Harnessing Solutions is increasingly in demand, says Felber. Under this brand name, LAPP supplies a wide range of pre-assembled cables. The technicians only have to plug in and secure the cables. There is no need to laboriously strip each individual cable and attach the connector in the rain and wind. This saves time and eliminates defects that cannot be completely ruled out with manual assembly on the construction site.
For LAPP Austria, the largest photovoltaic park in Austria is an important reference project, with more to follow. The company is now well connected, for example as a member of the Photovoltaic-Austria interest group, and Andreas Felber also regularly provides training for electrical planners and end customers, and also teaches at the technical college in Graz. "I''m always close to our customers and find out first hand what they need."
