The inquiry we get from high-rise condo communities comes in variations, but the core is always the same. There is a roof. There is a lot of Florida sun. There are a lot of electricity bills spread across dozens or hundreds of units. Why isn’t anyone doing something about this?
We get this question from individual unit owners, board members, and property managers. Sometimes it comes from a multi-building coastal complex where the board has just finished a major roof replacement and is thinking about what comes next. The answer is almost always the same, not because solar does not work or because Florida law makes it impossible, but because the physics and the utility billing rules make it extremely difficult to build a project that delivers what the inquirer has in mind.
Here is the honest breakdown of why these projects almost never go anywhere, and the narrow window where one might actually make sense.
What Individual Condo Unit Owners Can and Cannot Do
Start with the most common source of confusion. If you are a unit owner in a Florida condominium, you cannot install solar panels on the roof. Not because anyone is deliberately stopping you, but because the roof is not your property. It is a common element, owned collectively by all unit owners through the association. Florida Statute 163.04 protects solar access rights, but that protection applies to installations within the boundaries of your own unit. The roof is outside those boundaries. You have no unilateral right to install on it.
This is fundamentally different from a single-family home, where you own the roof and the decision is yours to make. In a condo, the roof belongs to the association, and any change to it is the association’s call.
The Governance Question Is Not the Main Obstacle
Many people assume that getting association approval is the biggest hurdle. Under Florida’s condominium statutes, changes to common elements typically require a member vote, and if the governing documents are silent on the threshold, Florida Statute 718.113 sets the bar at 75% of the total voting interest. Getting 75% of condo owners to agree on anything is an achievement in itself.
But here is what most people do not know. Florida Statute 718.113(7) creates a specific exception for solar energy systems. The board of directors can install solar collectors and other renewable energy devices on the common elements without a unit owner vote, regardless of what the governing documents say. The legislature intentionally cleared this path to make solar more accessible for condo communities. The board can act.
That is actually the easy part. What the board cannot do is make solar financially meaningful for individual unit owners. That is where the real problems begin.
The Energy Density Problem
This is the one that ends most of these conversations.
A high-rise condominium building consumes an enormous amount of electricity relative to the size of its roof. In Florida, a typical condo unit uses somewhere between 800 and 1,400 kilowatt-hours per month, depending on unit size, occupancy, and how hard the air conditioning works. A building with 100 units is consuming 80,000 to 140,000 kilowatt-hours per month at the unit level alone. Add the common area loads, elevators, hallway lighting, lobby HVAC, pool equipment, parking garage lights, and the building’s total demand is enormous.
Now look at the roof.
Rooftop area scales with the building’s footprint. Occupancy scales with the building’s height. The taller the building, the more energy it uses per square foot of available roof. A twenty-story tower with a 10,000 square foot footprint has the same roof as a two-story building sitting on the same lot. But it has ten times the occupants and something close to ten times the electricity demand.
On a realistically usable high-rise rooftop, after accounting for mechanical equipment, HVAC units, elevator machinery rooms, code-required setbacks, and the additional wind-exposure setbacks that engineers require at elevation on a coastal site, a solar designer might be able to fit 75 to 150 kilowatts of panels. In Southwest Florida, 100 kW of solar generates roughly 13,000 to 14,000 kilowatt-hours per month. That is a rounding error against a single building consuming 80,000 kilowatt-hours or more.
Even if you could somehow credit every kilowatt-hour of that solar production to individual unit owners, which you cannot, you would be shaving a few dollars off each unit’s monthly bill. The economics do not justify the investment under any realistic scenario for a high-rise.
Solar on the Roof Cannot Benefit Individual Unit Meters
This is the point that permanently closes the door for most of these inquiries.
Every condo unit has its own FPL account and its own utility meter. Common areas, lobbies, elevators, pool equipment rooms, have separate accounts and separate meters. These are completely distinct billing relationships with the utility.
A solar system installed on the roof connects to one utility account. Under FPL’s interconnection rules, the system’s production offsets consumption at that metered service location and nowhere else. Solar production cannot be allocated across multiple accounts. It cannot be divided among unit owners. It cannot reduce any individual owner’s FPL bill. The roof belongs to the association. Any solar system on that roof belongs to the association. The energy it produces goes to the association’s common area account, and only that account.
If a unit owner came to a board meeting expecting that the building’s new solar array would lower their personal $200 per month FPL bill, that is not how this works. There is no mechanism, no workaround, no software solution that credits rooftop solar production across individually metered utility accounts at the same property.
The Multiple Meters Problem
Even limiting the scope to the association’s own common area loads, the picture gets more complicated for larger complexes. A high-rise building often has more than one utility account serving its common elements. One meter for the parking garage. One for the pool and fitness center. One for the main lobby and corridors. One for the elevator machinery. In a multi-building development, each building may have its own set of common area accounts.
A solar system connects to one utility account. If the goal is to offset electricity costs across multiple common area accounts, you either need multiple solar systems, each designed, permitted, and interconnected separately, or you need a behind-the-meter electrical consolidation that pulls the relevant loads onto a single account before tying in the solar. Either path adds cost and complexity to a project that was already difficult to justify financially.
For a community with seven buildings, this means potentially designing, engineering, and permitting separate systems on seven separate rooftops, each sized to the unique common area loads of that individual building. The logistics and costs of that undertaking are significant.
Coastal Florida Adds Its Own Layer
This is not the primary obstacle, but it is worth naming. We have covered the challenges that high-rise coastal buildings present in the context of solar installations on high-rise condo properties before, and the core issues translate to photovoltaic systems as well.
Rooftop installations at elevation on a coastal site require higher-rated mounting systems to handle wind loads. Salt air accelerates corrosion on everything that is not properly specified. Aluminum racking and stainless or hot-dipped galvanized fasteners are non-negotiable on a beachfront property. Maintenance expectations are also higher than on an inland residential installation.
If a roofing contractor recently completed a roof replacement and issued a warranty covering workmanship and materials, that warranty may be voided by any rooftop penetrations or attachments made by a subsequent contractor. This is a real issue that needs a documented resolution between the association, the roofing contractor, and any solar contractor before a single panel goes up. It is not automatically a deal-breaker, but it requires coordination that adds time and cost.
Where Condo Solar Can Actually Make Sense
If you have read this far and I have burst your bubble, let me offer the honest opening that remains.
Low-rise or garden-style condominium communities, two or three stories, spread across a more generous footprint, have much more favorable energy density ratios. A 24-unit building with a sprawling single-story footprint might have enough usable roof space to produce solar energy that meaningfully offsets common area electricity costs. When the roof-to-floor-area ratio works in your favor, the numbers can pencil.
Even in higher-density settings, there is a scenario worth analyzing. If the association’s common area electrical loads are substantial, active pool equipment running year-round, significant HVAC for large shared spaces, a multi-level parking structure with continuous lighting, and the building has reasonably clean roof access, a system sized specifically for those common area accounts can deliver a legitimate return on the association’s investment. The key is matching the solar output to what the common area actually consumes. Not to the aggregate consumption of all units combined. When those numbers line up, the project can stand on its own.
Battery backup for common area loads is a separate conversation worth having, regardless of whether the solar math works. A battery system connected to the association’s common area service account can provide backup power for essential building functions during grid outages without requiring large roof-mounted arrays. For a coastal community where emergency power for elevators, lobby systems, and emergency lighting is a priority, that option often makes more practical sense than a full solar project.
The Bottom Line
If you are a condo unit owner who found this post because you want to put solar on the building and reduce your personal FPL bill, I want to save you several months of frustration. The solar panels on a shared roof cannot feed electricity to your individual utility meter. That is not a policy someone could change or an obstacle someone could navigate around. It is how utility interconnection works, and it is not going to change.
If you are a condo board member or property manager exploring solar for the association’s common area electricity costs, the conversation is worth having, but only with accurate expectations in place. The system can only offset consumption on the common area accounts. Energy density on a high-rise is fundamentally unfavorable. Multiple buildings multiply the complexity and the cost significantly.
We are glad to evaluate a condo community’s situation and tell you honestly whether the numbers support a project. For most coastal high-rise complexes, particularly larger multi-building developments, the answer is no. We would rather give you that read up front than let you spend months pursuing something that was never going to close.
