Frequently Asked Questions
Answers to common questions about solar energy and installations
The solar system size depends on your monthly electricity consumption. As a general guideline, 1 kW of solar generates approximately 4-5 units per day. For example, if your monthly bill indicates consumption of 300 units, a 2-3 kW system may be suitable. A professional site survey provides the most accurate recommendation.
The cost of a solar system depends on its capacity, type of components used, installation complexity and your location. Costs have been decreasing steadily. For an accurate estimate, we recommend requesting a consultation where we can assess your specific requirements and provide a detailed proposal.
A typical residential solar installation (up to 10 kW) takes 2-5 days for the physical installation. The overall timeline from enquiry to commissioning, including site survey, design, approvals and net metering, may take 4-8 weeks depending on the local distribution company processes.
An on-grid (grid-tied) solar system is connected to the utility electricity grid. It exports excess solar energy to the grid and imports power when solar generation is insufficient. On-grid systems support net metering, where you receive credit for exported energy. They are the most cost-effective solar option but do not provide backup during power cuts.
An off-grid solar system operates independently of the utility grid. It uses battery banks to store energy for use when panels are not generating. Off-grid systems are ideal for remote locations without grid access but are more expensive due to the battery component.
A hybrid solar system combines the features of on-grid and off-grid systems. It connects to the grid for net metering while also including battery storage for backup power during outages. Hybrid systems offer the best of both worlds but at a higher initial cost.
On-grid solar systems automatically shut down during power cuts for safety reasons (anti-islanding protection). Hybrid and off-grid systems with battery storage continue to provide power during outages, limited by battery capacity.
Quality solar panels are designed to last 25-30 years or more. Most manufacturers provide a 25-year performance warranty guaranteeing at least 80% of original output. The actual lifespan can extend well beyond the warranty period with proper maintenance.
Solar systems are low-maintenance. Regular cleaning of panels (every 2-4 weeks in dusty conditions) and an annual professional inspection are typically sufficient. There are no moving parts in a solar panel system, which contributes to their reliability and low maintenance needs.
Yes, solar energy can significantly reduce your electricity bill. The exact savings depend on your system size, electricity consumption pattern, tariff structure and local solar conditions. An on-grid system with net metering can reduce your grid electricity consumption substantially.
