Yes Solar provides a complete package of warranty information at the walk-through and will answer any questions. A dedicated service department handles any warranty claims, troubleshooting, or questions about production. If the local company is too small, or not local, a service department is handled on an ad-hoc basis, and if they have no in-house crews, how do they handle service? Ask how many service techs a solar company has on payroll, and what their qualifications are. Yes Solar has our most experienced installers on our Service crew.
