Solar questions

Choosing and maintaining a system

What determines the installed solar price?

Capacity, equipment, structure, cable routes, protection, labour, transport, taxes and site-specific work determine the quote. Request gross cost, exclusions and payment stages in writing; confirm subsidy separately.

Will rooftop solar run during a power cut?

A conventional on-grid inverter shuts down when the grid fails. Backup needs compatible equipment, storage, transfer/protection arrangements and circuits designed for that purpose.

Who owns the commercial solar system?

The stated commercial offer is customer-owned CAPEX. The customer purchases the scoped system; equipment, engineering responsibilities and payment stages are agreed in the proposal.

Can I choose 3, 5 or 10 kW from my bill alone?

Seasonal energy use, usable roof, shade, connection limits, daytime consumption and applicable export rules still need review. A capacity label does not define the installed package.

What does five-year support cover?

Five years of free labour and technician visits. Parts, replacements and manufacturer warranties are separate; confirm the applicable scope and exclusions in your quotation.

Is paid AMC the same as installation support?

No. Paid AMC needs its own inspection schedule, eligibility, scope, exclusions, charges and visit terms. Equipment warranty and the five-year labour/technician-visit commitment have separate responsibilities.

How is battery backup duration decided?

List simultaneous essential loads, starting power and required hours. Usable battery energy, losses, settings and equipment limits determine the design. PV kW, inverter kW/kVA and battery kWh are different quantities.

When can a survey or installation happen?

Agree timing after the locality, access, scope and equipment needs are reviewed. Approvals, site readiness and utility procedures can affect the sequence.

Do you serve places outside the four priority districts?

Prime Green Energies offers solar services across Andhra Pradesh from its Vizianagaram base. Share the district and locality to confirm scope, survey, travel and support arrangements.

Does residential subsidy apply to every solar project?

Eligibility, equipment and application conditions need checking through the current official process. Do not apply residential subsidy assumptions to a commercial project or a standalone battery purchase.

Can a battery be added to an existing solar installation?

Compatibility and retrofit acceptance need assessment before equipment is purchased. Share inverter, wiring and proposed load details; do not assume every installation supports backup.
