Solar pays back through lower bills and tariff protection.
A typical 3 kW system can cut monthly electricity costs significantly, with subsidies reducing the upfront investment.
Why solar
Benefits that matter to homeowners and facility owners.
The handbook highlights lower bills, tariff protection, reduced carbon footprint, and greater energy independence.
Lower electricity bills
The handbook frames rooftop solar as a way to reduce recurring grid electricity costs, with an example of over 90% monthly bill savings.
Protection from tariff increases
Solar generation gives homeowners a more predictable power source as electricity rates rise.
Lower carbon footprint
Rooftop solar is a clean, renewable energy source that can reduce greenhouse gas emissions.
Energy independence
Generating power at home reduces reliance on the grid and supports greater energy resilience.
Government subsidies
Central and state government subsidies can significantly reduce the upfront cost of solar installation, making it more accessible.
Increased property value
Homes with solar installations often see an increase in property value due to lower energy costs.
System design
Panels, inverters, mounting structures, and batteries shape the final design.
Choose between monocrystalline, polycrystalline, bifacial and Mono PERC panels; string or micro-inverters; and concrete or sheet rooftop mounting.
Sizing guide
Estimate annual generation and savings by system size.
The handbook uses 1,400 units per kW per year as a planning baseline, then adjusts for consumption, rooftop suitability, sanctioned load, and shading.

Three practical ways to think about solar investment.
Financing depends on loan type, subsidy eligibility, component choice, net-metering charges, and after-sales service.
Personal solar loan
Some banks offer solar loans, often with higher interest rates and more paperwork.
Solar bundled with home loan
A home-loan bundle can be an option for new builds; the handbook cites SBI as an example.
Subsidy-supported installation
The handbook includes subsidy examples such as ₹78,000 for a 3 kW system.
Solar Loans
Solar Financing & Loan Details
The handbook highlights options for solar financing including personal solar loans and home loan bundles.
| Loan Type | Collateral Requirement | Interest Rate | Key Details |
|---|---|---|---|
| Personal Solar Loan | Collateral-free (no personal assets required) | 16%–18% | Flexible, but has higher interest rates and paperwork |
| Bundled Home Loan | Your home serves as collateral | 10% | Can be bundled with a new build. State Bank of India (SBI) is the sole provider |
Suitability
Rooftop suitability & pre-installation checks
Before proceeding with a solar installation, verify your site against the handbook's key structural requirements.
Shadow-Free Space
At least 100 square feet of shadow-free rooftop space is required per kilowatt (kW) of capacity.
Discom Sanctioned Load
Sizing must align with the sanctioned load allowed on your electrical connection parameters.
Rooftop Material
Must be reinforced concrete, metallic sheet, or shingles. Asbestos roofs are structurally unsuitable.
System comparison
Choose the right solar architecture for the site.
On-grid, off-grid, and hybrid systems serve different reliability, backup, and net-metering needs.
| Type | Best for | Notes |
|---|---|---|
| On-grid | Urban areas with reliable grid power | Lower upfront cost, net metering, subsidy eligibility up to 10 kW, but does not prevent outages. |
| Off-grid | Rural or unreliable-grid locations | Uses battery storage, avoids outages, but has higher upfront cost and no net-metering benefit. |
| Hybrid | Homes that want both backup and grid interaction | Connected to the grid and batteries; typically the most expensive option. |
Components
The core parts of a rooftop solar system.
A rooftop solar system is an arrangement of panels, inverters, mounting structures, meters, and accessories working together.
- Solar panels convert sunlight into DC electricity.
- Inverters convert DC power into usable AC power for appliances.
- Mounting structures secure panels on metallic sheet or reinforced concrete rooftops.
- Bi-directional meters enable net metering and grid credit tracking.
- Accessories include cables, MC4 connectors, combiner boxes, conduit trays, earthing strips, and lightning arresters.

Panel types
Choosing between monocrystalline, polycrystalline, bifacial, and Mono PERC.
The handbook compares panel types by efficiency, appearance, cost, and best-use scenarios.
| Panel type | Efficiency | Cost | Best for |
|---|---|---|---|
| Monocrystalline | High (18–22%) | Higher upfront | Limited rooftop space, premium installations |
| Polycrystalline | Moderate (15–17%) | Lower upfront | Budget-conscious projects with adequate space |
| Bifacial | Very high (20–24%) | Premium | Ground-mount and elevated installations with reflective surfaces |
| Mono PERC | High (19–23%) | Mid-to-high | Best balance of efficiency and cost for rooftop systems |
Inverter choices
String inverters vs. micro-inverters for different site conditions.
The right inverter depends on rooftop layout, shading, budget, and long-term maintenance preferences.
String inverter
Multiple panels connected in a series to a single inverter. Cost-effective, reliable, and widely used.
- Lower cost, simpler maintenance, proven technology
Consideration: Performance affected if one panel is shaded
Micro-inverter
Each panel has its own inverter, converting DC to AC independently at the panel level.
- Individual panel optimization, no single point of failure, better performance in partial shade
Consideration: Higher upfront cost, more components to maintain
Mounting Structures
Sturdy & durable module mounting structures
The handbook details the specifications and selection of mounting structures to withstand high winds and minimize shadow risks.
Metallic Sheet Rooftops
Recommendation: Aluminium rail mounting structures
Lightweight, strong, secure fit directly on metal sheets
Reinforced Concrete Rooftops
Recommendation: Hot-dipped galvanised steel structures (6 to 9 ft tall)
Rust-proof, weather-proof, elevates panels to reduce shadow risks from surrounding structures
💡 Pro Tip from the Handbook
Ensure that your solar installer uses chemical anchoring to secure mounting structures. This technique uses waterproofing chemicals to make certain that the structure remains free of water seepage for a decade, while also filling in any minor cracks that may occur.
