Board Governance & Components

Solar Panels and HOA Reserves

Solar has become common enough that most HOAs now deal with it in some form — owner installations, community systems, or both — and it has specific reserve and governance implications. Like EV charging, solar mixes evolving legal protections with reserve components that have non-obvious lifespans. Here's how to think about solar and reserves.

General information, not legal advice — solar access laws vary by state; confirm specifics with counsel.

The Solar Access Landscape

Many states have solar access or solar rights laws that limit how much an HOA can restrict owner solar installations — conceptually similar to right-to-charge laws for EVs. The common pattern:

• Associations generally cannot prohibit or unreasonably restrict owner solar installations
• Associations can impose reasonable rules on placement, appearance, and installation that don't significantly impair efficiency or significantly increase cost
• The specifics — including what counts as "reasonable" and how much aesthetic control the HOA retains — vary considerably by state

Boards should know their state's solar access law before restricting installations, as a blanket prohibition is often unenforceable. (Climate and emerging reserve issues.)

The Two Models and Their Reserve Implications

As with EV charging, solar reaches reserves differently depending on ownership:

Owner-owned systems (on their unit or exclusive-use roof):

• The owner typically owns, maintains, and replaces the system
• The association's reserve concern is mainly coordination with roof replacement — if the owner's panels are on a roof the association maintains, replacing that roof requires removing and reinstalling the panels, which raises cost and responsibility questions
• Governing documents and agreements should clarify who handles panel removal/reinstallation during roof work

Association-owned systems (on common-area roofs/structures):

• The association owns the system and it becomes a reserve component
• The panels themselves are long-lived (often 25+ years), but key sub-components are not

The Inverter Trap

The most important solar reserve insight: the inverter outlives the panels far less. Solar panels themselves are long-lived (commonly 25+ years with gradual output decline), but the inverter — which converts the panels' DC power to usable AC — typically has a much shorter life (often roughly 10–15 years) and will need replacement one or more times during the panels' life.

A board that reserves for "solar panels" as a single 25-year item, and forgets the inverter, will be caught short when the inverter fails halfway through. Treat the inverter as its own shorter-life reserve component — this is the solar equivalent of the tile-underlayment trap or the gate-operator trap.

Roof Coordination Is Critical

Solar and roofing are deeply intertwined, and mismanaging the relationship is costly:

• Don't install solar on a roof nearing replacement — you'd pay to remove and reinstall panels soon after
• Sequence solar with roof replacement — ideally replace the roof first, then install solar, so the timelines align
• For existing owner panels on association roofs, the roof-replacement plan must account for panel handling and the associated cost and responsibility

Coordinating solar and roof timelines is one of the most important — and most overlooked — aspects of solar reserve planning.

Other Solar Reserve Considerations

• Monitoring and electronics — system monitoring and electrical components have their own finite lives
• Mounting and penetrations — roof penetrations must be properly waterproofed; failures create waterproofing and structural risk
• Batteries — if the system includes battery storage, batteries are a significant, finite-life component
• Incentives — federal, state, and utility incentives can offset installation costs (these change frequently)

Planning Solar in Reserves

1. Know your state's solar access law before restricting installations
2. Reserve for the inverter separately — it's much shorter-lived than the panels
3. Coordinate solar with roof replacement — sequence them, and plan panel handling during roof work
4. Clarify ownership and responsibility — owner vs. association systems, and panel handling during roof work
5. Account for batteries and electronics if present — finite-life components
6. Protect roof penetrations — waterproofing matters
7. Investigate incentives — they can meaningfully offset costs

The Bottom Line

Solar mixes evolving legal protections with reserve components whose lifespans aren't obvious — most importantly, the inverter, which fails well before the long-lived panels and is easy to forget. Know your state's solar access law, reserve for the inverter separately, and coordinate solar tightly with roof replacement to avoid paying twice. The boards that plan solar by its actual components — and sequence it with the roof — avoid the surprises that catch associations treating solar as one simple long-lived item.
