PV systems without storage

Buy a cheap PV system without storage for your home

A PV system without storage offers you an entry into solar energy at attractive rates. These grid-connected photovoltaic systems convert sunlight directly into usable electricity and feed excess energy into the public grid. Complete sets start from just €999 and include high-quality components such as 445-watt bifacial JA Solar modules and powerful inverters from Solis or Sofar. The systems achieve outputs between 3 kWp and 10 kWp, ensuring you can find the right solution for various household sizes.

Foregoing a battery storage system reduces the initial investment by 30 to 40 percent compared to hybrid systems. At PVundSO, you receive only components with CE conformity and VDE certification for the German market. Every system features Wi-Fi monitoring, allowing you to monitor your electricity generation at any time via smartphone. The bifacial glass-glass modules utilize not only direct sunlight but also reflected light from the back, increasing energy yield by up to 15 percent. Solar systems without storage are particularly suitable for homeowners with consistent daytime electricity consumption.

Solar system without storage and sustainably reduce electricity costs

The economic viability of a photovoltaic system without storage depends crucially on your consumption habits. If you use the generated electricity directly during production times, you can save up to 35 cents per kilowatt-hour compared to grid electricity. A 3 kWp system generates approximately 3.200 kWh annually and, with optimal self-consumption, pays for itself within 7 to 10 years. The current feed-in tariff is around 8 cents per kWh for surplus electricity, making direct consumption significantly more profitable.

Photovoltaic systems without storage achieve self-consumption rates between 25 and 40 percent, depending on your usage habits. Maximize your savings by operating energy-intensive appliances like washing machines, dishwashers, or heat pumps specifically during peak sunlight hours. Modern string inverters from Solis operate with efficiencies of 97,1 percent and convert direct current (DC) to alternating current (AC) with virtually no loss. Average costs range from €1.200 to €1.800 per kWp, with larger systems becoming proportionally cheaper. At an electricity price of 40 cents per kWh and 30 percent self-consumption, you can achieve annual savings of approximately €380 with a 3 kWp system.

Photovoltaics without storage is only useful with high daily consumption

Using a PV system without storage effectively means adapting your energy needs to the hours of sunshine. If you work from home, operate commercial premises with daytime hours, or use electric water heating, you'll benefit most from this configuration. Peak production time is between 9 a.m. and 16 p.m., when solar panels reach their maximum output with optimal orientation. Households with an average daily consumption of 2.000 kWh can cover up to 1.200 kWh directly from the system.

The system size depends on your available roof area and electricity consumption. A 5 kWp system requires approximately 25 to 30 square meters and generates 5.000 to 5.500 kWh of electricity annually. Whether a PV system without storage is worthwhile for your home can be determined by analyzing your recent electricity bills. If your daily consumption between 8 a.m. and 18 p.m. exceeds 40 percent of your total consumption, you will achieve economically attractive self-consumption rates. Installation on south-facing roofs with a 30 to 35-degree pitch delivers optimal yields. East-west orientations also work well, as they better cover morning and evening electricity demand, although with a 10 to 15 percent lower annual yield.

Maximizing self-consumption of photovoltaic power without storage

Optimizing self-consumption of a PV system without storage requires strategic consumption management. Intelligent timers automatically activate household appliances during daylight hours. Modern energy management systems communicate with the inverter and initiate energy-intensive processes when sufficient solar power is being produced. You can increase your direct consumption from 30 to up to 50 percent through consistent load shifting.

Using your own photovoltaic electricity without storage is particularly efficient for continuous consumers. An 800-watt pool pump consumes 6 kWh daily during the summer months, which you can cover entirely with solar power. Air conditioners, refrigerators, and freezers run continuously and use the generated electricity directly. For photovoltaic systems without grid feed-in and without storage, you install an inverter with grid protection, which automatically shuts down the system in the event of a power outage. These systems operate purely as consumption systems without a bidirectional meter and do not feed any surplus electricity into the grid. For maximum energy independence with a PV system without storage, combining it with a hot water immersion heater is recommended. This heat heater thermally stores excess electricity and thus makes it indirectly usable.

Photovoltaic system without storage using bifacial modules

The complete photovoltaic system without storage from PVundSO relies on premium bifacial modules from JA Solar. This glass-glass technology utilizes light incidence from both sides and achieves module efficiencies between 20,5 and 22 percent. The black frame blends seamlessly into modern roofscapes, while the bifacial structure generates up to 30 percent additional yield on light-colored surfaces. Each module delivers 445 watts of nominal power and comes with a manufacturer's warranty of up to 12 years.

Solis and Sofar string inverters feature integrated Wi-Fi modules for continuous monitoring. They collect real-time data on power generation, grid feed-in, and system status via smartphone apps. The devices operate with two to three MPP trackers, which independently optimize different module strings. This is particularly advantageous in cases of partial shading or varying roof orientations. All components comply with VDE standards for grid connection and grid protection. Complete installation, including the mounting system, cabling, and electrical work, can be completed within two to three working days. PVundSO provides ready-to-ship packages containing all necessary components and German-language installation instructions for professional installation.
