Payback possible in 3-7 years depending on your consumption. Technical details and brand comparison below.
Understanding Your Needs Before Choosing
Calculate Your Consumption Baseline
Before investing in a plug and play solar panel, precisely identify your energy needs by consulting your Linky meter.
The consumption baseline represents the power constantly consumed by your home, even when you're not actively using any appliances. It corresponds to equipment running 24/7: refrigerator, freezer, internet box, standby appliances, electric water heater during off-peak hours.
How to measure your baseline:
- Check the instantaneous power on your Linky meter one evening around 11 PM
- Make sure all non-essential appliances are turned off
- The displayed value (in Watts) corresponds to your consumption baseline
- This data determines the minimum panel power to choose
A French household generally has a baseline between 300W and 800W. This measurement guides your choice: a 400 Wp kit covers a 400W baseline, an 800 Wp kit (2 panels) is suitable for 800W.
Evaluate Your Available Space
Installing a plug and play solar kit requires a clear, sunny space with specific technical constraints.
Required surface per panel:
- 1 standard panel: approximately 1.7-2 m²
- 2 panels: 3.5-4 m²
- 4 panels maximum: 7-8 m²
Optimal location criteria:
- Ideal South orientation (South-East to South-West acceptable)
- 30-35° tilt for maximum yield
- Complete absence of shading even temporary (trees, buildings, chimneys)
- Distance to outdoor electrical outlet less than 10 meters
- Stable surface: ground, wall, balcony or flat roof
Check the condominium regulations if you live in an apartment. Some prohibit installation visible from outside, while others require prior authorization from the general assembly.

Define Your Investment Budget
The price of a plug and play solar panel varies considerably depending on power, component quality and included services.
Price ranges by configuration:
| Configuration | Power | Average Price | Annual Savings |
|---|---|---|---|
| 1 panel kit | 300-420 Wp | €350-700 | €80-120 |
| 2 panel kit | 800-900 Wp | €1200-1600 | €180-250 |
| 3-4 panel kit | 1500-2000 Wp | €1800-2500 | €350-500 |
Average profitability is between 3 and 7 years depending on your self-consumption rate and electricity price. A high self-consumption rate (immediate use of produced electricity) accelerates payback.
Regular increases in electricity rates progressively reduce the payback period, making the investment even more relevant in the long term.
Technical Criteria for Choosing
Panel Power: Adapt to Needs
The peak power of a solar panel, expressed in Watt-peak (Wp), indicates its maximum production under optimal sunlight conditions.
Selection guide according to consumption:
| Consumption Baseline | Recommended Power | Number of Panels |
|---|---|---|
| 200-400W | 300-400 Wp | 1 panel |
| 400-800W | 800-900 Wp | 2 panels |
| 800-1200W | 1200-1600 Wp | 3-4 panels |
Warning: the actual power produced represents approximately 75-80% of the advertised peak power. A 400 Wp panel will actually produce 300-320W in average real conditions.
To effectively cover your consumption baseline, favor a power slightly higher than your measured need. A 500 Wp panel is perfectly suitable for a 400W baseline.
Expandable kits allow you to progressively add additional panels. This modularity proves practical for adjusting your installation according to the evolution of your energy needs.
