Frequently Asked Questions

We leave no question unanswered. If your question is not listed here, please feel free to contact us directly.

Why should I work with GIGA.GREEN as an SME?

GIGA.GREEN enables you to benefit from cheap solar energy without your own investment costs. We take care of everything — from planning to maintenance.

Isn't a solar system too expensive for my company?

With GIGA.GREEN, you bear no investment costs. Our PPAs offer you stable and affordable electricity prices over the long term, which reduce your energy costs.

How much time does my company need to invest in the implementation?

Minimal. GIGA.GREEN takes care of the entire project, allowing your company to focus on its core business.

How can I be sure that a PV system is worthwhile for my company?

Our experts conduct a detailed profitability analysis that demonstrates how your company can benefit from cost savings and sustainable energy.

What are the insurance obligations?

The system comes with all-risk insurance, covering all damage caused to or by the investment due to external circumstances. However, damages caused by the building (e.g., a fire that damages the system) are excluded, and the customer must insure against such risks accordingly.

Can I obtain electricity from GIGA.GREEN if I don't own the property?

Yes, with the landlord's approval. The contractual relationships are: a lease agreement between the building owner and GIGA.GREEN, and a power purchase agreement between the tenant and GIGA.GREEN.

How long does the system last?

The modules are very durable and have a performance guarantee of 85% after 25 years. Some of the inverters can fail during their 20-year run time, but are then repaired or replaced.

What happens when the property is sold?

There is no change in the operation of the system. The new owner can enter into a power purchase agreement with us. In addition, the investment, e.g. by credit institutions or potential buyers, is valued as an upgrade of the property.

How can GIGA.GREEN support my company with multiple locations?

GIGA.GREEN offers customized, standardized energy solutions for your entire site network. We handle financing, project planning, and operations at all locations.
