Photovoltaic Glass for Apartment Balconies<\/h1><\/div><\/div>Hot water from the sun. Directly from your balcony.<\/strong><\/p>\nTurn the glazed surface of your balcony into a discreet source of energy.<\/p>\n
Our system uses semi-transparent, tinted, or colored photovoltaic glass installed on the balcony to produce electricity locally. The energy is used directly to heat domestic hot water through a standard electric boiler.<\/p>\n<\/div>

<\/span><\/div>Why balconies?<\/strong><\/p>\nBecause most apartments do not have real access to the roof.<\/p>\n
Conventional photovoltaic panels are difficult to install on apartment buildings. You need space, approvals, electrical routes, agreements, and interventions in the common parts of the building.<\/p>\n
Instead, many apartments already have an unused energy surface: the glazed balcony.<\/p>\n
Photovoltaic glass uses this surface to produce energy exactly where it is consumed: inside the apartment.<\/p>\n<\/div>
- <\/i><\/span>It does not turn the balcony into a power plant.<\/div><\/li>
- <\/i><\/span>It does not promise total energy independence.<\/div><\/li>
- <\/i><\/span>But it can reduce costs and increase comfort, year after year.<\/div><\/li><\/ul>
How the system works<\/strong><\/p>\nThe photovoltaic glass produces direct current during the day, depending on light, orientation, season, and weather conditions.<\/p>\n
During daylight hours, the energy produced by the glass is sent directly to the electric boiler, where it heats domestic hot water.<\/p>\n
In the evening, the system automatically switches to the grid to complete the hot water demand, so that hot water remains constantly available.<\/p>\n
In practice, the boiler becomes the \u201cbattery\u201d of the system.<\/p>\n
It stores the energy produced during the day as hot water, without the cost, losses, and complexity of an electric battery.<\/p>\n
The system works locally, inside the apartment.<\/p>\n<\/div>
- <\/i><\/span>It does not inject energy into the grid.<\/div><\/li>
- <\/i><\/span>It does not require a bidirectional meter.<\/div><\/li>
- <\/i><\/span>It does not require a prosumer contract.<\/div><\/li>
- <\/i><\/span>It does not modify the building\u2019s electrical installation.<\/div><\/li><\/ul>
Why we do not use an inverter and batteries<\/strong><\/p>\nFor an apartment, a conventional photovoltaic system with an inverter and batteries can become expensive, complicated, and difficult to recover financially.<\/p>\n
The inverter and the battery increase the initial cost of the system and reduce the net energy available to the user because of conversion losses, storage losses, and self-consumption.<\/p>\n
We chose a simpler and more efficient solution for apartments: the energy produced by the photovoltaic glass is used directly to heat domestic hot water.<\/p>\n
The boiler practically becomes the \u201cbattery\u201d of the system.<\/strong><\/span><\/p>\nIt stores the energy produced during the day as hot water, without the cost, losses, and complexity of an electric battery.<\/p>\n
This keeps the system more affordable, more robust, and better suited for apartment buildings.<\/p>\n<\/div>

<\/span><\/div>What benefits do you get?<\/strong><\/p>\n1.<\/span> You reduce the cost of hot water<\/strong><\/p>\nA significant part of the energy needed for hot water can come directly from the sun.<\/p>\n
In the pilot system tested in an apartment in Bucharest, the photovoltaic glass covered approximately 42% of the energy required for hot water over more than 32 months of real operation.<\/p>\n
This is not a simulation.<\/p>\n
This is not an optimistic estimate.<\/p>\n
These are measured data from a real apartment.<\/p>\n
2.<\/span> You reduce the heat entering through the balcony in summer<\/strong><\/p>\nSemi-transparent, tinted, or colored photovoltaic glass reduces part of the solar radiation entering through the balcony.<\/p>\n
This means less overheating in summer and lower air-conditioning consumption.
The glass does not only produce energy.<\/p>\n
It also works as integrated solar protection.<\/p>\n
3.<\/span> You use a surface that already exists<\/strong><\/p>\nThe balcony is already there.<\/p>\n
You do not need a roof.<\/p>\n
You do not need land.<\/p>\n
You do not need a separate structure for conventional panels.<\/p>\n
Instead of allowing the glazed surface to only let heat in, it can produce useful energy for the apartment.<\/p>\n
4.<\/span> You get a discreet solution integrated into the balcony<\/strong><\/p>\nThe glass looks like modern tinted or colored glazing, similar to decorative or solar-control glass already used on balconies and fa\u00e7ades.<\/p>\n
It is not made of conventional panels mounted on the fa\u00e7ade.<\/p>\n
It does not take up space inside the apartment.<\/p>\n
It does not radically change the appearance of the building.<\/p>\n
The solution is suitable for enclosed balconies, existing frames, or new projects where the glass can be integrated directly into the window frames.<\/p>\n<\/div>
<\/i><\/div><\/div>Take advantage of solar energy too and save substantially on your utility bill in the long run!<\/span><\/p>\n<\/div><\/div><\/div>
