Planning and system size
Electricity use, daytime consumption, usable roof area, shade, connection type and future loads shape the system. A bill-only estimate is useful for planning but not final design.
Savings, subsidy and metering
Savings depend on generation, self-consumption, tariff and applicable metering. Subsidy and utility procedures can change, so confirm current official requirements before ordering.
Safety, warranty and maintenance
Compare complete equipment and installation warranties, exclusions, service access and monitoring. Safe roof access, electrical protection, earthing and planned inspection matter throughout the system life.
Common questions
Can rooftop solar run all appliances in my home?
A correctly designed system can generate energy for a home's overall consumption, but instantaneous appliance operation, sanctioned load, grid availability and backup behavior depend on the system type and electrical design.
Will on-grid solar work during a power cut?
A standard on-grid inverter normally shuts down during a grid outage for anti-islanding safety. Backup requires a compatible hybrid or off-grid design with batteries and selected backup circuits.
How much roof area does 1 kW require?
A rough planning range is about 80–100 square feet per kW, but module size, access paths, setbacks, shade and roof geometry can change the usable capacity.
How accurate is the solar calculator?
It is an educational first estimate. Final generation, cost and savings require roof, electrical, load and current tariff information.
Is subsidy guaranteed?
No. Eligibility, process, approved equipment, commissioning and payment depend on current official rules and the relevant authority.
How often do panels need cleaning?
Frequency depends on dust, rain, roof angle, bird activity and nearby roads or industry. Monitoring trends help determine when cleaning is actually needed.
Do you provide battery backup?
Battery and hybrid options can be assessed around essential loads, required backup duration, battery lifecycle and budget.
What should I keep ready for a site survey?
Recent electricity bills, connection details, property access, roof information and a list of critical backup loads are useful starting points.
