Frequently asked questions
Can I use plug-in solar in Montana today?
No statewide plug-in-specific framework was verified in the tracked sources. That does not mean plug-in solar is automatically prohibited; utility and existing rules require research.
Does the watt limit refer to panel watts?
Do not assume so. Compare the final law’s definition with continuous inverter AC output; panel DC nameplate capacity is a different figure.
Will exported electricity be credited?
No export payment or retail credit is assumed here. Ask the serving utility how the meter treats surplus generation and size around daytime self-consumption.
Does a compliant product remove landlord or HOA rules?
No. State energy rules do not grant permission to alter a rented home, common property, balcony rail or façade. Obtain written consent and check local requirements.
Is system-level UL 3700 certification verified for these products?
No product is presented here as having verified system-level UL 3700 evidence. Confirm the precise complete-system listing and all conditions before purchase.
