Contact FAQs
Quick answers before you reach out.
What do you need to start a design?
An address and a few photos are often enough to begin. For best results, share roof plans (if available), desired system size, equipment preferences, and any utility bill or production target.
What’s your typical turnaround time?
Most residential designs are delivered in 1–2 business days after we receive complete inputs. Commercial timelines vary by scope and modeling requirements.
Do you support commercial projects?
Yes. We model commercial projects in Aurora Solar and can support advanced production and financial modeling with Helioscope and Energy Toolbase when required.
Do you work nationwide?
Yes, GreatSun Consulting provides remote design outsourcing and consulting across the United States.
