Affordable 10 kWp Solar System for Self-Assembly Now Available at Rock-Bottom Prices in the SSV Market

For those with higher energy demands, such as water heating or heat pump operation, solar power systems can be an ideal solution. In this article, we'll explore two DIY solar power systems – a 13.3-kWp and a 16.02-kWp system – and discuss their benefits, installation process, and cost-effectiveness.

The 13.3-kWp System

This system, consisting of 30x 445 Watt Trina Solar Vertex S+ Glass-Glass solar modules, offers an annual yield of approximately 12,683 kWh. It also includes a 10 kWh SAJ LiFePO4 storage, an SAJ HS2-10K-T2-X inverter, a smart meter, and costs 4,985 Euro.

The installation process involves measuring the available roof area, creating an occupation plan, lifting or cutting out tiles at the intended fixing points, screwing special roof hooks onto the roof truss, aligning and securing mounting rails, and connecting solar modules in series with pre-assembled MC4 plugs. However, it's important to note that wiring of solar modules is usually done directly on the roof and requires careful work.

With a payback period of approximately 2.1 years, the 13.3-kWp system offers a quick return on investment. However, DIY solar system installation is not recommended for complete beginners without any handyman experience. It requires technical understanding, precision, and safe handling of tools.

The 16.02-kWp System

This larger system, with a performance of 16.02 kWh, consists of 36x 445 Watt Trina Solar Vertex S+ Glass-Glass solar modules, a 10 kWh SAJ LiFePO4 storage, an SAJ HS2-10K-T2-X inverter, a smart meter, and costs 5,339 Euro.

The 16.02-kWp system is ideal for higher energy demands and offers an annual yield of approximately 15,219 kWh. It also boasts a payback period of approximately two years.

The installation process for this system is similar to that of the 13.3-kWp system. However, due to the increased size, more careful planning and consideration of individual factors are required beforehand.

Once the system is installed, a qualified electrician will handle the final electrical connection to the house network and commissioning.

Long-Term Profitability and Savings

The long-term profitability of DIY PV system installation is hardly beaten, provided that planning, assembly, and registration are carried out carefully. DIY solar systems offer a savings potential and can save up to 10,000 euros on purchase costs, ensuring a significantly faster amortization.

For those who prefer a professional installation, there are numerous solar power providers available. A free PV provider comparison on Solaranlagen-Portal.com allows you to request up to five offers from specialist companies.

In conclusion, DIY solar power systems offer maximum independence and a particularly quick return on investment. Whether you choose a 13.3-kWp or a 16.02-kWp system, careful planning, technical understanding, and safe handling of tools are essential for a successful installation.
