Yes, solar panels can bypass inverters under specific circumstances. The key condition is that the device you want to power needs to be compatible with DC (direct current) electricity, which solar panels produce. Most home appliances are built for AC (alternating current) and require an inverter for conversion.
Here’s where inverter-less setups become more applicable:
Off-grid living: People living off the grid and generating their power may use inverter less systems to directly power specific DC appliances like small DC motors, water pumps designed for DC use, or lights with compatible voltage.
Portable applications: Inverter less setups can be handy for portable applications like powering USB-chargeable devices with a DC converter. This can be useful for campers or hikers who want to charge their gadgets with solar power.
However, there are limitations to consider when skipping the inverter:
Limited appliance compatibility: Most appliances rely on AC, making them incompatible with inverter less solar setups.
Voltage matching complexities:
Matching the voltage output from your solar panels to the exact voltage required by the device can be tricky. It might involve connecting multiple panels in series or parallel to achieve the correct voltage, adding complexity to the system.
Safety limitations:
Inverter less systems might lack safety features built into inverters, like automatic shut-off during grid outages or fault conditions. This can pose safety risks.
Inverters take the DC output from solar panels and convert it to usable, AC electricity that can run your home’s appliances and connect to the grid if you have net metering.

Conclusion:
While it is possible to bypass inverters and directly use solar panels for DC-compatible devices, this setup comes with significant limitations. It is mostly applicable for off-grid living or portable applications where DC appliances are used. The main challenges include limited appliance compatibility, the complexity of voltage matching, and potential safety concerns. For most household applications, an inverter remains necessary to convert solar-generated DC into the AC power that standard appliances require.
FAQ's
While it is not common, it is possible to use a solar panel directly without a battery or the grid as a reference, but you need to use an electronic called DC to DC converter, which stabilizes the voltage at a certain level.
