About solar in Paris 13 Gobelins
Paris 13 Gobelins, France has a temperate climate with meaningful seasonal variation in solar resource. Its annual peak sun hours average 3.31 kWh/m²/day, a moderate solar resource by global standards.
The strongest month in Paris 13 Gobelins is June (summer) at 5.81 kWh/m²/day, and the weakest is December (winter) at 0.8 kWh/m²/day. When sizing a year-round off-grid system, it's standard practice to design against the December value rather than the annual average — otherwise the battery bank runs low during the darkest weeks.
Given the moderate resource, Paris 13 Gobelins installations typically oversize panels or combine solar with another source (grid, generator, hydro) for reliability.
FAQ
- What are the peak sun hours in Paris 13 Gobelins?
- Paris 13 Gobelins averages 3.31 peak sun hours per day annually, ranging from 0.8 in December to 5.81 in June.
- How many solar panels do I need in Paris 13 Gobelins?
- Panel count depends on your daily load. At Paris 13 Gobelins's annual average of 3.31 kWh/m²/day, a 5 kWh/day load needs roughly 5 × 400 W panels. Use the calculator above for your actual load.
- What size battery do I need in Paris 13 Gobelins?
- Sizing against Paris 13 Gobelins's worst month (December, 0.8 kWh/m²/day) with 2 days of autonomy at 80% depth of discharge, a 5 kWh/day load needs about a 12.5 kWh battery bank.
- How does Paris 13 Gobelins's solar resource compare globally?
- Paris 13 Gobelins sits in solar zone 2 out of 5 (where 5 is strongest) at 3.31 kWh/m²/day — moderate by global standards. For reference, top-tier desert sites average ~6.5 and high-latitude cities around 2.5 kWh/m²/day.
- How much does winter reduce solar output in Paris 13 Gobelins?
- Paris 13 Gobelins's worst month (December) delivers 0.8 kWh/m²/day — about 14% of the summer peak of 5.81. Off-grid systems here typically oversize 1.5–2× or pair with a backup source.
- Do cloudy days significantly affect Paris 13 Gobelins's solar?
- Partly. Diffuse light still produces 10–25% of clear-sky output. Paris 13 Gobelins's 3.31 kWh/m²/day already reflects average cloudiness, so no further derating is needed for sizing.
- What panel tilt works best in Paris 13 Gobelins?
- At Paris 13 Gobelins's latitude (49°), a fixed tilt near 49° balances year-round yield. Winter-heavy loads favor latitude + 15°; summer-heavy, latitude − 15°.
