What are the component costs for a 4-module system?
| Component | Price Range (€) | DRBO Greenenergy Recommendation |
|---|---|---|
| 800W Inverter | 200–400 | EZ1 or Deye models |
| 4 Solar Modules (200 Wp) | 400–800 | Bifacial modules for higher yield |
| Cables & Mounts | 50–150 | Weather-resistant accessories |
| Total | 650–1,350 | From €700 in a set |
DRBO Greenenergy bundles all components into complete packages for straightforward installation.
What are the installation costs for DIY vs. professional?
DIY installation: €0–100 (tools). Professional installation: €200–500. Total setup: DIY €700–1,400, professional €900–1,800. DRBO Greenenergy offers plug-and-play sets for easy self-assembly. Professional installers check VDE standards and secure warranty claims.
Which subsidies reduce the 800W setup costs?
KfW grants: up to 30% (max. €1,900/kWp), EEG surcharge savings: 8–12 Ct/kWh, regional subsidies: €100–300. Applications can be made via BAFA or the municipality. DRBO Greenenergy supports subsidy applications. Net costs are reduced to €400–800.
How long does it take for an 800W system with 4 modules to pay for itself?
With an annual yield of 800 kWh and savings of €0.30/kWh, the system pays for itself in 3–5 years. South orientation maximizes yield. With SunLit storage from DRBO Greenenergy, self-consumption can increase to 70%, reducing the amortization period to 2–4 years.
What are the additional costs for accessories and storage?
Accessory costs: €50–200 for cables, protective boxes; SunLit storage: €300–600. Total budget increases by 20–50%. DRBO Greenenergy recommends storage for using solar energy even at night.
| Additional | Cost (€) |
|---|---|
| Energy Manager | 100–200 |
| Balcony Storage (SunLit) | 400–800 |
| RCD (FI Switch) | 50–100 |
Are 800W inverters with 4 modules cost-effective?
Yes, they generate 700–900 kWh/year at €0.7–0.9/Wp and are more efficient than 600W systems. DRBO Greenenergy test sets confirm savings of up to 20% compared to smaller systems.
DRBO Greenenergy Expert Opinions
"For an 800W system with four modules, we recommend complete sets starting from €700. High yield at moderate costs, combined with SunLit storage, increases self-consumption by up to 40%. With subsidies, the investment amortizes in 3 years. Quality over cheap products ensures long-term reliability and low failure rates."

Which hidden costs should be avoided?
Hidden costs arise from incorrect installation (repair approx. €200) or unsuitable cables (failure approx. €100). DRBO Greenenergy minimizes risks through certified complete packages and regular checks.
When is it worth investing in an 800W system?
When electricity prices exceed €0.30/kWh and in sunny locations. Balconies larger than 4m² offer optimal conditions. DRBO Greenenergy provides individual calculations for quick amortization.
Conclusion
An 800W inverter with four modules costs €600–1,500 and amortizes in 3–5 years. Subsidies and DRBO Greenenergy complete sets with SunLit storage reduce costs and increase self-consumption. Start with a price calculation and subsidy check – your decentralized energy transition begins efficiently and cost-effectively.
