In 2021, Switzerland's photovoltaic (PV) installations increased to 685 MWp from 475 MWp in 2020. The Federal Energy Act, revised and effective from January 1, 2018, changed the support scheme for PV systems: it extended the one-time investment subsidy to all sizes of PV systems, ranging from 2 kW to 50 MW. Additionally, in 2022, the investment subsidy formula was updated to encourage investments in larger PV capacities and more efficient use of rooftop space. [pdf]
Among the innovative solutions paving the way forward, solar energy containers stand out as a beacon of off-grid power excellence. In this comprehensive guide, we delve into the workings, applications, and benefits of these revolutionary systems.
Comprising solar panels, batteries, inverters, and monitoring systems, these containers offer a self-sustaining power solution. Solar Panels: The foundation of solar energy containers, these panels utilize photovoltaic cells to convert sunlight into electricity. Their size and number vary depending on energy requirements and sunlight availability.

Batteries: Equipped with deep-cycle batteries, these containers store excess electricity for use during periods of low sunlight.

This paper explores how these containers address key site challenges: their rugged, forklift-friendly design (paired with 30–80 kW solar canopies) cuts diesel generator runtime by 55% (saving ~€5,940/month in fuel costs, per EREC 2025 data); smart load balancing supports peak tools like electric cranes while aligning with the EU Circular Economy Action Plan (reusable across 5+ projects); and a 3.2-year payback period (IEA 2025) plus eligibility for €72B EU JTM funding boosts contractor ROI.

On average, the container home cost starts at approximately CHF 50,000 for a basic model, making it a truly affordable container home option compared to traditional housing. For those seeking more luxurious features or multi-container designs, prices can range upwards of CHF 150,000..

For those seeking more luxurious features or multi-container designs, prices can range upwards of CHF 150,000.. In general, a basic solar trailer (plug-and-play PV only) starts around €21,500 for a 12.6 kWp system with 41 kWh battery, while mid-range hybrid containers (80–200 kW PV with LiFePO₄ storage) often cost €30,900–€43,100; small off-grid units can be found for ~$9,850–$15,800, and turnkey BESS containers (500 kW–2 MWh) command $180,000–$190,000 or more.

The solarfold Container is an immaculately-detailed and sophisticated plug & play system for a wide range of applications. The mobile drive system consists of a flexible drive unit mounted on traverses and can also be used for other solarfold PV power plants.
The Solarcontainer is a photovoltaic power plant that was specially developed as a mobile power generator with collapsible PV modules as a mobile solar system, a grid-independent solution represents. Solar panels lay flat on the ground. This position ensures maximum energy harvest Panels lays flat on the ground.
The innovative and mobile solar container contains 196 PV modules with a maximum nominal power rating of 130kWp, and can be extended with suitable energy storage systems. The lightweight, ecologically-friendly aluminium rail system guarantees a mobile solution with rapid availability. at full power.
Major construction sites require large volumes of electricity. Solarfold can produce clean and environmentally-sustainable electricity, particularly when immense volumes of energy are needed in inaccessible areas. When construction work is completed, the mobile Solar Container can be taken down and transported to the next project site.
Based on an average power consumption of a 4-person household of 4000 kWh per year and a location in Southern Germany, the solar container can supply approx. 32 households with climate-friendly electricity. At a location in Southern Europe it can even be up to 50 households due to the high solar radiation.
The free monitoring app is part of your package and enables you to monitor the solarfold Container at any time, and from anywhere. The comprehensive functionality of the app supplies data about yield, energy flow and the amount of electricity currently being fed into the grid – and all in real-time.
