Solar Carport Costs: Prices, Funding and What Really Pays Off in Hanover

A carport that not only protects your car but also generates electricity: more and more homeowners in Hanover and the surrounding region like this idea. But before deciding, almost everyone asks the same question: what does a solar carport actually cost? This guide gives you an honest overview of solar carport costs, the individual cost components, funding, and a clear assessment of when the investment pays off.

One clarification up front, because it makes the biggest difference to the price: we plan and build your solar carport completely, from the supporting structure in wood, aluminium or steel to the finished photovoltaic system including grid connection. So you don’t need an existing carport frame. All prices in this article refer to this complete solution of structure plus PV system. If you already have a carport and only want a PV system on its existing roof, get in touch. That’s also possible and usually cheaper, because the structure isn’t needed.

Solar Carport Costs at a Glance

Depending on size, material and features, solar carport costs range from around €8,000 to €25,000 for the complete solution. A single parking space with about 3 to 5 kWp typically costs €8,000 to €13,000, and a double carport with 5 to 7 kWp €14,000 to €22,000. High-end premium solutions or systems with a large battery can cost more than €30,000.

The good news is that prices have fallen noticeably in recent years, mainly because solar modules have become much cheaper. At the same time, electricity prices remain high, which makes self-generated solar power all the more attractive.

Importantly, these figures are guide values for the complete carport solution. The actual price depends heavily on your property, the desired output and the features. You’ll only get a reliable quote after individual planning on site.

What Makes Up Solar Carport Costs?

Solar carport costs reflect two functions: protecting your vehicle and generating electricity. The total consists of three main components.

Supporting structure: the carport frame itself. The material is the main price factor here. Wood is cheapest to buy but needs regular care. Aluminium is a little more expensive but rust-free, light and virtually maintenance-free, and often the most economical choice over its lifetime. Steel offers maximum stability but is heavier and needs more corrosion protection.

Photovoltaic system: the solar modules and the inverter. Carports often use glass-glass modules, which double as the roof covering and replace a separate roof. That typically saves €1,500 to €3,000 compared with a normal carport with a PV system added on top.

Installation and electrical work: assembly, cabling, grid connection and registration with the grid operator and in the Market Master Data Register. In Germany, only a registered electrical specialist may carry out the electrical installation.

Optionally, you can add a wallbox for your EV and a battery. Both increase the investment but raise self-consumption considerably.

PVPro Solar: Your Solar Carport from a Single Source

Structure and PV System from One Company

We build the carport in wood, aluminium or steel and the photovoltaic system on top. You have one contact for structural design, assembly, electrics and registration, instead of coordinating a carport builder and a solar installer yourself.

Structural Design and Building Law Checked in Advance

We design the structure for modules, snow and wind, and check with the building authority before construction whether your carport is permit-free or needs permission.

Brand Components and Our Own Electricians

Modules from AIKO, JA Solar or Longi, a Fronius inverter and an optional BYD battery. Electricians from our team handle the electrical installation to VDE standards and registration with the grid operator, which in Hanover is usually enercity Netz.

Fixed Price and Payment Using the 30/70 Model

You get a written fixed price for the carport and PV system and pay using the 30/70 model. On request, we plan a wallbox and battery at the same time; more under PV with heat pump and wallbox.

Solar Carport Costs With or Without a Battery

A solar carport without a battery is cheaper and pays off especially if you use a lot of power during the day or regularly charge your EV during the day. Then you use the solar power at the very moment it’s generated.

A battery becomes interesting if you also want to use your own power in the evening and at night. Without a battery, a typical household uses about 25–35% of its solar power itself, and about 55–70% with a battery. The cost of a battery depends on its capacity. For a BYD HVS 10.2, we calculate around €7,700–9,200, and smaller batteries cost less. Whether the extra investment pays off depends on your consumption profile. Read more under home battery storage.

The combination of a solar carport, wallbox and EV fits especially well: if the car is under the roof during the day, it charges exactly when the modules deliver the most power. Instead of paying 40 to 60 cents per kilowatt-hour at a public charging station, you only pay the generation cost of your own solar power, a fraction of that.

Solar Carport for a Motorhome

A normal car carport is simply too low for a motorhome. Production vehicles are usually between 2.80 and 3.20 metres high, and larger alcove or integrated models sometimes more. If you want to park your motorhome under cover and supply it with your own solar power, you need a structure designed specifically for it.

We build motorhome solar carports with a clearance height from about 3.20 metres, which is enough for most motorhomes. For larger vehicles, we clarify the exact height in advance based on your vehicle’s dimensions. Because of the larger footprint and the taller, more stable structure, a motorhome solar carport costs more than a normal double carport, usually around €16,000 to €24,000 for a complete solution with 6 to 8 kWp.

One technical note: we mount the solar modules on the carport roof, not on the vehicle’s roof. Flexible 12-volt modules directly on a motorhome roof are a separate, much smaller system for the on-board battery and no substitute for a grid-connected carport system.

0% VAT and Funding

Since 1 January 2023, the zero VAT rate under Section 12(3) UStG has applied. No VAT is charged on the PV components, or on batteries installed together with the system, if the system belongs to a residential building. You automatically save 19 percent, without any application. The carport structure itself doesn’t fall under this rule as construction work, and the standard rate also applies to the wallbox.

In the Hanover region, proKlima’s DachVollToll programme funds PV systems on the roofs of existing residential buildings, while funds last and if you apply before placing the order. According to proKlima, applications for 2026 are possible until 31 October 2026. The programme is designed for building roofs, and carport roofs aren’t explicitly mentioned. Clarify directly with proKlima before planning whether your carport project is still eligible. We’ll do this for you on request. For financing, the KfW 270 loan is also available, which is a loan and not a grant. You’ll find all programmes under solar funding in Hanover.

When Do Solar Carport Costs Pay Off?

Whether solar carport costs pay off can’t be stated across the board. A worked example for a typical single carport system with 5 kWp in the Hanover region makes it tangible:

• Annual yield: around 4,500 kWh (893 kWh per kWp, our standard value for the Hanover region)
• Self-consumption: an assumed 50%, realistic if the EV charges under the carport during the day. That’s around 2,250 kWh used on site and 2,250 kWh fed in.
• Savings from self-consumption: 2,250 kWh × 37 cents (assumed electricity price) ≈ €830 a year
• Feed-in revenue: 2,250 kWh × 7.70 cents (partial feed-in, systems up to 10 kWp) ≈ €170 a year
• Total benefit: around €1,000 a year

With an investment of around €10,500 for this carport size, the simple payback period is about 10 to 11 years for the complete carport solution. Looking only at the PV share compared with an identical carport without PV, the extra cost usually pays for itself much faster. How realistic 50% self-consumption is for you depends on your consumption profile and charging behaviour. We discuss this in the free consultation using your own figures.

As of October 2026. The feed-in tariff falls slightly about every six months, and the rate for your system depends on the month of commissioning. According to the government’s draft EEG amendment 2027, the fixed tariff for new small systems is set to fall significantly from 2027.

The wallbox can be calculated too: if you drive around 15,000 kilometres a year at about 18 kWh per 100 kilometres, you need about 2,700 kWh of charging power a year. If you charge most of it with solar surplus from your own carport instead of at a public charging station, you save several hundred euros a year on top, depending on the share.

Regardless of the numbers, a carport has value as weather protection anyway, and a solar carport can also increase the value of your property.

Do You Need Building Permission?

As a guide in Lower Saxony, garages and carports with a footprint of up to 30 square metres are usually exempt from permits under the Lower Saxony Building Code, as long as they comply with the development plan and the setback distances to the property boundary. Outside this scope, permission is generally required, especially if:

• the carport is to be built directly on the boundary or closer than the required distance,
• it’s a taller motorhome carport that exceeds the limits for permit-free garages, or
• the development plan doesn’t provide for a carport at that location.

The exact rules vary by municipality and development plan, so we check the planning situation for your project in advance with the responsible building authority. Building without the required permission risks fines and, in the worst case, having to remove the structure.

One technical note: if the solar modules act as the roof covering over the parking space (overhead glazing), special requirements apply under DIN 18008. In that case, overhead-certified modules or an additional safety net are used.
