Myth 1: "Payback is 1–3 years"

Reality: Payback is typically 5–7 years for most setups.

This myth comes from manufacturer marketing that uses best-case assumptions: maximum solar irradiance, peak electricity rates, and 100% self-consumption. Real-world payback depends on your actual electricity rate, your location's solar resource, and how much of the generated power you actually use.

In high-rate states (California, Massachusetts, Connecticut) with TOU optimization, 3–5 year payback is achievable. In low-rate states (Louisiana, Idaho), payback may exceed 10 years.

Myth 2: "You need landlord permission"

Reality: In California and several other states, you don't.

Utah's HB 340 (2025) is the only enacted US law that explicitly gives residents the right to install plug-in solar without utility approval. Virginia, Colorado, Vermont, and 21 other states have active bills advancing in 2026. Check the State Tracker for the current status in your state.

Even in states without explicit rights, many landlords will agree if you approach it correctly — emphasizing no structural modifications and offering to remove the system when you leave.

Myth 3: "It's not powerful enough to matter"

Reality: A 600W system can offset 15–25% of a typical apartment's electricity use.

A 600W system in a 4.5 peak sun hour location generates about 2.2 kWh per day, or ~800 kWh per year. The average US apartment uses 6,000–8,000 kWh per year. That's 10–13% of total consumption — meaningful, even if not transformative.

In a smaller apartment with lower consumption, or in a high-sun location, the percentage can be higher. The key is matching system size to your actual consumption and available space.

Myth 4: "It's dangerous to plug solar into a wall outlet"

Reality: UL 3700 certified systems are designed specifically for this application and are safe.

The concern about "backfeeding" power into the grid is valid for DIY microinverter setups without proper safety equipment. But commercial plug-in solar systems with UL 3700 certification include all the necessary safety features — anti-islanding protection, ground fault detection, and overcurrent protection — to make this safe.

This is why we emphasize UL 3700 certification. Don't buy a system without it.

Myth 5: "It only works on sunny days"

Reality: Modern LFP batteries store energy for use anytime, regardless of current weather.

The battery is the key. Solar panels generate power when the sun shines. The battery stores that power for use whenever you need it — cloudy days, evenings, or during peak-rate hours. A 1.6kWh battery can power a typical apartment's evening electricity needs (lights, TV, phone charging, small appliances) for several hours.

Even in cloudy climates like Seattle or Portland, plug-in solar generates meaningful power — just less than in sunnier locations. The economics are less favorable, but the system still works.
