Practical guides to help you understand rooftop solar before you invest.

Solar Energy Basics

Solar photovoltaic panels convert sunlight into electricity. Rooftop systems reduce grid dependency and can lower monthly bills depending on tariff and generation.

On-Grid vs Off-Grid vs Hybrid

On-grid systems connect to the utility network. Off-grid systems use batteries independently. Hybrid systems combine solar with battery backup for selected loads.

Solar Panel Technologies

Common module technologies include mono PERC and other high-efficiency crystalline panels. Choice depends on space, efficiency, warranty, and budget.

Solar Inverter Information

Inverters convert DC from panels to AC for appliances. Sizing should align with system capacity and phase type.

Solar Battery Information

Batteries store energy for backup or off-grid use. They add cost and require appropriate charge controllers / hybrid inverters.

Rooftop Installation Guide

Assess roof strength, orientation, shading, cable routes, earthing, and structure type (RCC, tin, sloping, or ground mount).

Solar Maintenance Tips

Keep modules clean, inspect mounting hardware, monitor inverter status, and schedule periodic electrical checks.

Solar Savings Guide

Savings depend on system size, generation, self-consumption, tariff, and any applicable subsidy. Use our calculator for indicative estimates.

Rooftop solar panels convert sunlight into DC electricity. An inverter converts this to AC power for home or business use. In on-grid systems, surplus energy can be exported to the grid under net metering rules where available.

Indicative costs vary by panel quality, inverter brand, roof type, structure, and location. Use our Solar Calculator for an estimate, then request a site-specific quotation from Wattmeister Energy LLP. Prices shown in the calculator are configurable estimates, not final quotes.

Generation depends on system size, location, roof orientation, shading, and weather. A common planning estimate is around 4 units per kW per day, but actual output varies. Our calculator uses a configurable monthly generation factor.

PM Surya Ghar: Muft Bijli Yojana is a central government rooftop solar scheme for eligible residential consumers. Subsidy amounts and eligibility are governed by official rules and should be confirmed on the official portal.

Typical residential installations may take a few days to a few weeks depending on site readiness, material availability, and DISCOM permissions. Commercial timelines vary with project size.

Payback depends on electricity tariff, system cost after subsidy (if applicable), generation, and consumption pattern. The calculator provides an estimated payback based on configured assumptions.
