Autonomous solar kit 90W – Production up to 540Wh/day at 12V

The energy produced by this photovoltaic solar kit allows you to power your applications in isolated site, not connected to the grid: small autonomous dwelling, garden shed, telecommunication site, water pumping, leisure installation (boat, camping, hiking, shed, etc.).

This kit operates at 12V, with a 90W monocrystalline solar panel and a 12/24V 10A solar charge controller.

In good sunlight conditions, it allows producing an average of up to 540Wh per day.

What can be powered with this kit?

Depending on the season, region, and sunlight, this 90W kit can, for example:

• Power 12V LED lighting (a few low-consumption bulbs for several hours per evening)
• Recharge phones, tablets, small USB devices via an appropriate converter
• Power a small 12V pump (irrigation, water circulation) for limited durations
• Provide a base of energy for a small shelter, cabin, stationary camper, in addition to other sources

For more intensive uses (refrigerator, powerful tools, electric heating, etc.), larger panel and battery capacities or a higher-end solar kit will be needed.

Contents of the 540Wh/day solar kit

• 1 monocrystalline solar panel 90W – 12V system
  (Variable dimensions depending on arrival, see technical sheet below)
• 1 solar charge controller 12V/24V 10A of PWM type
• Wiring to be planned according to your installation (battery(ies), cable lengths, protections, etc.)

💡 Indicative production:
Up to ~540Wh/day based on approximately 6 hours of useful sunlight. This value is indicative and strongly depends on the region, season, orientation, and tilt of the panel.

Operating principle

1. The solar panel converts solar energy into electrical energy at 12V.
2. The charge controller protects the battery and optimizes the charge according to its state.
3. The battery stores energy to power your devices when you need it (day, evening, or night).
4. Your 12V devices connect directly to the battery or via a 12V → 230V converter if you want to power standard household appliances.

Sizing advice

• The current that the solar panel must provide depends on the total consumption of your installation (in Wh or Ah per day).
• The required power in the battery corresponds to the total power (W) consumed by the installation (in 12V or via a 230V converter) over a day.
• A 12V/230V converter consumes a bit of energy: allow for a margin compared to the total power of your devices.
• The solar panel only provides its nominal current with good sunlight.
  • Rather than counting 10h of sun, it is generally considered 6h of useful sunlight on average, or the panel is slightly oversized.

Best usage practices

• Install the panel facing south (in France) with an inclination suitable for your region and the season.
• Use cables with a suitable cross-section for the length and current (limit voltage drops).
• Protect the installation with appropriate DC fuses or circuit breakers.
• Use a quality battery (AGM, GEL, or other compatible battery) to optimize the system's lifespan.
• Regularly check the connections and the condition of the cables to ensure safety and performance.

Warranty & support

• Product warranty: 2 years on the kit (panel + regulator, excluding consumables, see general conditions).
• Specific warranties on the panel power:
  • 90% Pmax guaranteed 12 years
  • 80% Pmax guaranteed 25 years
• Email support via our customer service to help you choose the battery, converter, or additional accessories (cables, protections, mounts, etc.) suitable for your project.
