Why Renters Are the Biggest Audience for Balcony Solar
Around 19% of households in England rent privately — approximately 4.6 million households. The vast majority of those renters have no access to rooftop solar, not because their home couldn't support it, but because they don't own it. Landlords have little financial incentive to fund rooftop installations that primarily benefit their tenants, and tenants can't install permanent electrical systems without consent.
Balcony solar exists precisely to break this deadlock. A plug-in system requires no permanent electrical work, can be removed completely when you leave, and in most configurations requires no drilling at all. It's the one form of renewable energy generation that is realistically available to renters without a lengthy and often fruitless negotiation with a landlord.
The Legal Picture for Renters in 2026
The Renters' Rights Act 2025 changed the legal landscape for tenants in England in several important ways. While it primarily addresses security of tenure and rent increase mechanisms, it also strengthened tenants' rights around reasonable home improvements. Landlords can no longer unreasonably withhold consent for alterations that would ordinarily be considered minor and reversible — and a portable, removable balcony solar system increasingly falls into this category.
That said, the Act doesn't give tenants carte blanche. You still need to notify your landlord, and in practice the most sensible approach is to seek written consent before installing anything — not because the system is inherently problematic, but because maintaining a good landlord relationship is almost always worth more than the principle of the thing. If your landlord refuses, the no-drill options below mean you can often proceed without affecting the structure of the property at all.
Check your lease agreement first
What Systems Work Best for Renters
For renters, the most important criteria when choosing a balcony solar system are portability, minimal footprint, and no-drill installation. These requirements point clearly towards certain system types and away from others.
Railing-Clamp Systems
The most renter-friendly option in most cases. Railing-clamp mounts grip your balcony railing — typically a tubular steel or concrete-capped railing — using adjustable clamps. No drilling, no fixings into walls or floors, and they can be removed and refitted in minutes. The panel typically hangs at a near-vertical angle from the railing, which reduces annual output slightly compared to an optimal tilt, but is more than acceptable for the convenience gained.
Floor-Stand Systems
If your balcony has a solid floor and enough space, a freestanding floor mount — essentially an adjustable tripod or A-frame — is another excellent no-drill option. These allow you to set the tilt angle properly (30–45°), improving output, and they leave zero trace when removed. The downside is that they take up more floor space and may need to be weighted or tied down in windy conditions.
Avoid Wall-Bracket Systems
Wall-bracket mounting requires drilling into the masonry or render of the building. For renters, this is generally not advisable without explicit written landlord permission — both because of the lease implications and because any damage to brickwork or render can result in deductions from your deposit. If you want a fixed-angle mount and your landlord has given permission, a wall bracket is a sound option — but don't go there without that agreement in writing.
The case for no-drill systems
Juliet Balconies
A large proportion of UK flats — particularly those built since the 1990s — have Juliet balconies: the full-height glass or metal railing panels set into the exterior wall, with no usable floor space beyond the doorway. These are common in purpose-built apartment blocks and converted commercial buildings.
Juliet balconies can still support balcony solar, but your options are more limited. Standard railing-clamp mounts designed for horizontal railings don't always work on vertical glass balustrades. However, several manufacturers now produce Juliet-specific mounting systems that clamp to the frame of the balustrade rather than the glass. These typically support a single panel oriented vertically, which reduces output but is manageable. Alternatively, if you have a flat roof above a ground-floor flat, a discreet floor-stand installation may be possible — worth discussing with your landlord.
East and West Facing Balconies
The majority of balconies in UK apartment blocks face east or west rather than south — a consequence of how developers lay out buildings to maximise natural light to living rooms throughout the day. This isn't ideal for solar, but it's far from a dealbreaker.
An east-facing balcony receives morning sun; a west-facing balcony gets afternoon sun. In terms of annual output, east and west orientations deliver roughly 65–70% of what a south-facing installation would generate. Crucially, the time of day your panels generate matters too. If you work from home and make heavy use of electricity in the mornings, an east-facing system is well-matched to your consumption. If you're a morning commuter who returns in the evening, a west-facing system delivers generation at a time when you're actually home and using electricity — which is better for self-consumption than a south-facing system generating at noon when you're in the office.
What Happens When You Move?
This is one of the questions renters most frequently ask, and the answer is reassuring: balcony solar systems are designed to be moved. A railing-clamp or floor-stand system can be fully dismantled and repacked in under an hour. There's nothing to fill, no damage to repair, and nothing left behind.
The only practical consideration when moving is whether your new property will be suitable. If you're moving from a flat with a south-facing balcony to one with a north-facing balcony, your system's performance will change. But the hardware itself is entirely reusable, and most panels and inverters carry multi-year warranties that transfer with the equipment regardless of where it's installed.
DNO Notification as a Renter
Connecting any generation to the grid — including a plug-in balcony solar system — technically requires notifying your Distribution Network Operator (DNO) under Engineering Recommendation G98. This applies to renters in exactly the same way as homeowners: you notify as the person connecting the generation, not necessarily as the property owner.
In practice, the G98 notification is a simple online form submitted to your regional DNO. You don't need your landlord's involvement, and the DNO doesn't contact your landlord. The notification simply informs the network operator that a small generation unit is connected at your address. Most DNOs process these automatically for systems under 3.68kW — which covers all balcony solar systems — without any follow-up.
See our full G98 guide for the step-by-step process and a table of DNO contact details by region.
Getting Landlord Permission
If you need your landlord's permission — whether because your lease requires it or because you want to use a wall-mount system — the approach matters. Landlords who are unfamiliar with balcony solar often have unfounded concerns about structural damage, insurance, or fire risk. A well-framed conversation or letter can address these before they become objections.
The key points to make are:
- The system is fully removable and leaves no trace (for railing or floor-stand systems)
- It plugs into a standard socket — no electrical work is done to the property
- The equipment carries CE marking and meets relevant safety standards
- It doesn't affect building insurance (the system is your personal property, not the building)
- Similar systems are already in widespread use across Europe without incident

Tips for Getting the Most from Balcony Solar as a Renter
- Use a smart plug and timer to run your washing machine or dishwasher during midday — this shifts your consumption to when your panels are generating, improving self-consumption significantly.
- Consider a battery if you're out during the day. Systems like the EcoFlow STREAM with an integrated battery store daytime generation for evening use, transforming the economics for anyone with a 9-to-5 routine.
- Monitor your system via the app to understand when you're generating and align your habits accordingly.
- Keep your G98 notification confirmation in case your energy supplier or landlord ever queries the system.
