eParking Solar

How can you turn this to your advantage?

An increasing number of companies are exploring ways to turn their parking lots into profitable assets. They are often intrigued by the idea of converting parking spaces into solar canopies. However, many of these potential solar canopy customers have common questions and concerns. They want to know about the design of these structures, the optimal number of charging systems for electric cars, how to utilize excess solar energy production, the space required for external battery containers and inverters, the amount of soil that needs to be excavated for installation, and the potential impact of one module malfunctioning on the rest of the system.

Furthermore, the perspective of electric vehicle users is important in this discussion. They often ponder, “Where can I conveniently charge my electric vehicle?” Many don’t have the space for home charging, find commercial chargers expensive, and lack a garage for this purpose.

This presents a remarkable opportunity for parking lot owners and management companies to transform their spaces into valuable assets. It encourages individuals who lack access to home or workplace charging options or those looking to avoid the cost of installing a charger at home to consider alternative services.

Time is an invaluable resource, and at Tonomia’s eParking Solar, we firmly believe in optimizing it. Why not empower your employees or customers to charge their electric vehicles right in the parking lot while they work or shop for groceries? This convenience is available whenever your vehicle is parked, whether you’re at the office, train station, attending an exhibition, or even during a hospital visit. The possibilities are limitless.

    Shopping centers, exhibition venues, and parking management firms are actively exploring ways to attract more customers and encourage longer and more frequent visits. Currently, paid parking lots struggle to generate significant profits, while free lots drain valuable resources. What if the pricing per kilowatt-hour (kWh) could vary throughout the day? How can we turn these parking facilities into profitable ventures?

    Electricity distribution operators, or GRIDs, are grappling with the growing challenge of network congestion caused by the proliferation of renewable energy producers. They seek solutions to efficiently transport excess energy generated by these new renewable sources from residential areas to businesses. eParking offers a solution: why not store surplus energy for later use or produce it during off-peak hours when costs are lower? Owners of photovoltaic panels also face grid congestion issues, as their inverters may stall when solar production outpaces consumption.

    Public and local authorities are contemplating strategies to promote electric mobility and boost local business foot traffic simultaneously. They ponder how to address the risks associated with fluctuating electricity prices or how to harness cheap or even free electricity. Is energy storage now a profitable endeavor?

    In an era of increasing water scarcity and rising costs, preserving this precious resource becomes paramount. Rainfall on concrete parking lots often goes to waste. How can we effectively collect and locally utilize this water resource?

    All-in-one smart solar eParking module:

    1. Electricity
    2. Heat
    3. Storage
    4. Fast charging
    5. Thermal cameras monitoring the quality of solar panels
    6. Self-cleaning solar panel system
    7. Intelligent E-Box for Module System Control
    8. Wi-Fi and 4G/5G connectivity

    The modules, designed for either 2 or 4 parking spaces, come in the shape of a Y-infrastructure for 4 parking spaces or a ½ Y-infrastructure for 2 parking spaces. The primary supporting pillar is a hybrid structure, combining wood and metal, featuring a rainwater reservoir that collects all the precipitation gathered by the photovoltaic panels. This harvested water serves multiple purposes, such as cooling the storage batteries, automatically cleaning the solar panels, and can be distributed to various locations, including parks, restrooms, car washes, and other electricity-consuming facilities.

    The photovoltaic panels deliver an impressive output of 10 kWp, covering an area of approximately 46 m² for 4 parking spaces and nearly 23 m² for a module accommodating two parking spaces. This energy production translates into an estimated annual generation of 10 MWh, equivalent to the power consumption of 2.5 households.

    The eParking solar carport module is seamlessly integrated, eliminating the need for bulky external battery containers that might otherwise occupy space designated for additional parking spots. Within the central pillar, the batteries are cleverly integrated, capable of storing the energy equivalent to the consumption of 15 households (any surplus energy beyond panel production is drawn from the grid) or accommodating the charging needs of 30 electric vehicles daily.

    This unit incorporates a 30 kW inverter, effectively managed by the batteries and their individual charging capacities, facilitated by an advanced Battery Management System. The batteries can be charged either through the power generated by the photovoltaic panels or via the public grid (GRID). A common concern with photovoltaic panels is the risk of inverter shutdown during grid congestion. To mitigate this, we’ve adopted an innovative approach, optimizing electricity supply. Stored energy is intelligently distributed to all interconnected modules, ensuring the reliable operation of electric vehicle chargers, thereby guaranteeing the availability of electricity for each EV’s charging needs.

    The compact, liquid-cooled chargers operate silently, delivering a consistent current.

    The potential capacity of an eParking module, designed for 4 parking spaces, varies depending on the number of parked vehicles. It can be configured for 4 cars charging at 30 kW (when all 4 parking spaces are occupied), 2 cars at 60 kW (with 2 parked vehicles), or 1 car at 120 kW (for a single parked vehicle).

    In Northern Europe, a single 4-space module can collect an estimated 40 m³ of water, equivalent to the capacity required for 200 car washes within the same parking area.

    During the mid-season and summer, the solar panels generate heat, which can be efficiently captured through ducts beneath the photovoltaic panels. This heat can then be utilized, thanks to interconnections between modules, to warm the air using a heat pump.

    Lastly, the entire eParking Solar structure is supported by a partially buried base anchored with 4 high-pressure-driven anchors into the ground. This base also serves as a protective buffer, preventing any inadvertent damage to the structure or vehicles by electric vehicle drivers.
