PVPro Solar: Your Photovoltaic Provider in Laatzen

Our Own Certified Installers

Our own installers work on your roof, not changing subcontractors. A registered electrician handles the electrical connection of the inverter, battery and meter cabinet. That has a simple advantage for you: whoever plans the system is also responsible for installing it. If questions come up later, you talk to the same company, not three different ones.

Brand Components We Know

We install modules from AIKO, JA Solar and Longi, Fronius hybrid inverters, BYD batteries and K2 Systems mounting. We deliberately work with a small number of manufacturers whose products we know from daily installation work and who have a contact in Germany. That way, the inverter and battery are sure to work together, and spare parts are available. Our quotes always list the exact model names.

Written Fixed Price and Fair Payment

After the on-site visit, you receive a written fixed-price quote. Scaffolding, installation, electrical work, meter cabinet adjustment, grid operator registration and entry in the Market Master Data Register are included. Payment follows the 30/70 model: 30% on order, 70% only once the system is installed. So you never prepay the full amount.

Experience with proKlima Funding

Laatzen is part of proKlima’s funding area. Funding is only available if you apply before placing the order and cover all suitable roof areas. We plan the system from the start so that it meets the conditions and give you the documents you need for the application. The same applies to the Hanover Region’s Dach-Solar programme.

Short Distances from Hanover to Laatzen

Laatzen borders directly on Hanover. For us, that means the on-site visit is quickly arranged, installation involves no long journey, and if anything needs clarifying after commissioning, we can be with you quickly.

Our Project in Laatzen-Rethen

In Rethen, we installed a 10.23 kWp system: 24 JA Solar modules of 425 Wp each, a Fronius GEN24 Plus hybrid inverter and a BYD HVS 10.2 battery. The total investment was €21,400. The yield forecast for this particular roof is about 9,800 kWh per year. For a general calculation in the Hanover Region, we use a more cautious figure of about 893 kWh per kWp, i.e. just under 9,000 kWh for 10 kWp. You’ll find more projects in our references.

Our Services in Laatzen

PV System for Your Home

We plan the system to match your consumption, on south-facing, east-west or flat roofs. Without storage, households typically use 25 to 35% of their solar power themselves. What’s included in the package is explained under complete solar systems.

Battery Storage, Including Retrofits

With a BYD battery, self-consumption rises to around 55 to 70%. If you already have a system, we check whether and how a battery can be retrofitted. More under retrofitting a solar battery.

Backup Power

The Fronius GEN24 Plus has a built-in backup power socket. With an additional transfer switch, the system supplies the whole house during a power cut. More under solar backup power systems.

Wallbox for Your Electric Car

With PV surplus charging, your electric car charges with the solar power that is currently left over. We install the wallbox and handle registration with the grid operator. More under home wallbox installation.

Heat Pump

We also install heat pumps and design them together with the PV system and battery, so as much solar power as possible goes into heating and hot water. If you already have a heat pump, we size the PV system to match its consumption. More under combining a heat pump with PV.

Balcony Power Plant Installation

For tenants and flat owners, we install balcony power plants securely with K2 brackets and check the connection. More under balcony photovoltaic system.

PV Systems for Businesses

For businesses in Laatzen, we plan systems based on the load profile so that as much solar power as possible is used on site. More under commercial photovoltaics.

How We Work: Your Project in 5 Steps

1. Enquiry: postcode, approximate annual consumption and whether you’d like a battery.
2. On-site visit: we check the roof, structure, shading and meter cabinet, free of charge.
3. Fixed-price quote and funding applications: you receive the written quote and apply to proKlima and the Region using our documents.
4. Installation: on a single-family home, our installers usually complete the system in one to two days.
5. Commissioning: after the meter replacement, we commission the system, enter it in the Market Master Data Register and show you the app.

How Much Does a Solar System Cost in Laatzen?

Our guide price is about €1,450–1,750 per kWp, including installation, registration and commissioning:

Supply and installation of the system and battery on or at residential buildings are subject to 0% VAT. At an assumed electricity price of 37 ct/kWh, every self-consumed kilowatt-hour is worth almost five times the roughly 7.70 ct feed-in tariff. More under solar panel costs.

Funding in Laatzen: proKlima and the Region

• proKlima DachVollToll: €100 per kWp, up to €2,000, from 2 kWp, if all suitable roof areas are covered, while funds last. Apply before placing the order.
• Hanover Region, Dach-Solar: €150 per m² of module area above the legal minimum on existing buildings. Dach-Solar, however, is only available with simultaneous roof insulation and from a calculated grant of €4,000. Apply before placing the order.

• KfW 270 loan: a low-interest loan, not a grant

Under the planned EEG amendment 2027, only systems commissioned by 31 December 2026 are certain to receive the fixed tariff for 20 years. All programmes are listed under solar funding in Hanover.

Grid Connection in Laatzen

In most of Laatzen, enercity Netz is the responsible grid operator. In some districts, it may be a different operator. We check this for your address and handle the registration.

How to Check Our Quote

We want you to check our quote carefully, just as you would any other. Pay attention to these points:

• Price per kWp: divide the price without battery by the system output.
• Usable battery capacity: what counts is the usable kWh, not the gross figure.
• Model names: the manufacturer and exact model of every component must be in the quote.
• Scope: scaffolding, meter cabinet, registration and commissioning should be included.
• Yield forecast: realistic for your roof, not inflated.
• Payment plan: no high prepayment.
