Solar Basics

Essential information about solar energy systems and how they work

What is a solar rooftop system?

A solar rooftop system is a power generating arrangement where solar panels are installed on the roof of a building to convert sunlight into electricity. It's an efficient way to generate clean, renewable energy while utilizing otherwise unused roof space.

How does a solar rooftop system work?

Solar panels convert sunlight into DC electricity through photovoltaic cells. An inverter then converts this DC power into AC power, which can be used to run household appliances. Excess power can be stored in batteries or fed back to the grid through net metering.

What are the different types of Solar systems?

There are three main types of solar systems: Grid-tied (connected to the power grid), Off-grid (completely independent with battery storage), and Hybrid systems (connected to the grid with battery backup). Each type suits different needs and situations.

Do solar panels generate electricity even during monsoon and winter?

Yes, solar panels continue to generate electricity during cloudy weather and winter, though at reduced efficiency. Even on overcast days, some sunlight reaches the panels. Modern solar panels are designed to work effectively even in diffused light conditions.

Does a rooftop solar PV system generate power during a power failure?

Grid-tied systems typically shut down during power failures as a safety measure. However, systems with battery backup or hybrid systems can continue to provide power during outages, making them ideal for areas with unreliable grid supply.

What is the electricity output of a solar plant?

A solar plant's output depends on several factors including system size, location, panel efficiency, and weather conditions. Generally, a 1 kW system can produce 4-5 units (kWh) of electricity per day in optimal conditions.

What appliances can run on solar power?

You can run any standard electrical appliance on solar power, including AC, refrigerator, TV, washing machine, and lights. The key is to size your system appropriately to meet your power requirements.

Installation

Everything you need to know about solar panel installation

What are the requirements for installing a rooftop solar system?

You need adequate roof space with good sun exposure, structural stability assessment, necessary permissions from local authorities, and connection approval from your electricity distributor. A site assessment by solar experts can help determine your roof's suitability.

How do I decide what size of plant I need?

The size of your solar plant depends on your electricity consumption, available roof space, budget, and energy goals. Review your past electricity bills, consider future consumption changes, and consult with solar experts for optimal sizing.

Can Solar projects damage my roof?

When installed properly by qualified professionals, solar panels will not damage your roof. In fact, they can protect your roof from weather elements. Professional installers use appropriate mounting systems and waterproofing techniques to ensure roof integrity.

My roof is not made of concrete; can I still install a Solar Project?

Yes, solar panels can be installed on various roof types including metal, tile, and asphalt shingle roofs. Different mounting systems are available for different roof materials. A structural assessment will determine the best installation method.

Maintenance

Information about maintaining your solar power system

What is the life of a rooftop solar system?

A well-maintained solar system typically lasts 25-30 years. Solar panels come with 25-year performance warranties, though they continue to produce energy beyond this period at slightly reduced efficiency. Inverters usually need replacement after 10-15 years.

Do Solar Rooftop projects have a high maintenance cost?

No, solar systems have minimal maintenance requirements. Regular cleaning and basic annual inspections are usually sufficient. There are no moving parts in the system, which reduces wear and tear. The main component that might need replacement is the inverter after 10-15 years.

Do I need to clean my Solar plant?

Yes, regular cleaning is recommended to maintain optimal performance. Dust and debris can reduce efficiency. Cleaning frequency depends on your location and environment, but typically once every 2-3 months is sufficient. Simple water cleaning is usually adequate.

Costs & Savings

Information about costs, savings, and financial aspects

What is the cost of a solar power plant?

The cost varies based on system size, quality of components, and type of installation. Generally, residential systems range from ₹40,000 to ₹60,000 per kW before subsidies. Commercial systems may have different pricing due to scale advantages.

What is the break-even period for Solar rooftop projects?

The typical break-even period is 3-5 years, depending on your electricity consumption, tariff rates, and system cost. With government subsidies, this period can be shorter. Solar systems provide returns for 20+ years after breaking even.

Are there any subsidies provided by the government for solar projects?

Yes, the government offers subsidies for residential rooftop solar installations. Currently, subsidies up to 40% are available for systems up to 3kW, and 20% for systems between 3kW to 10kW. Specific subsidy amounts vary by state.

What is the difference between CapEx and OpEx models?

In the CapEx (Capital Expenditure) model, you purchase the solar system outright. In the OpEx (Operational Expenditure) model, a developer installs and maintains the system, and you pay for the electricity generated at an agreed rate. Each has its advantages based on your investment capacity and preferences.

Are financing options available for Solar Rooftop projects?

Yes, many banks and NBFCs offer solar-specific loans with attractive interest rates. Some offer up to 80% financing of the project cost. These loans often come with longer repayment terms and sometimes with additional benefits for green energy projects.
