What is solar energy and how does it work?

Solar energy is the light and heat that comes from the sun. We can turn this sunlight into electricity using solar panels. These panels collect sunlight and convert it into a type of electricity called DC (Direct Current). But our home appliances need AC (Alternating Current). So, a machine called an inverter changes this DC into AC, and then the electricity powers your lights, fans, fridge, and more.

A solar power plant is a facility designed to generate electricity on a larger scale using solar energy. It consists of multiple solar panels installed across a large area to collectively produce significant amounts of power. The electricity generated is then transmitted through power grids for public or industrial use.

  • Sunlight hits the photovoltaic (PV) panels.
  • The panels generate Direct Current (DC) electricity.
  • An inverter converts DC into Alternating Current (AC), which is suitable for home or commercial use.
  • The AC power is used on-site or fed into the power grid

A solar system is like a mini power plant on your roof. The main parts are:

  • Solar Panels – Capture sunlight.
  • Inverter – Converts electricity into usable form.
  • Mounting Structure – Holds the panels on your roof.
  • DC/AC cables – Carry electricity.
  • Battery (optional) – Stores power for use during power cuts.
  • Monitoring system – Shows performance on your phone or computer.
  • On-grid (grid-tied) systems are connected to the electricity board. If your solar panels make more power than you need, it goes to the grid, and you get credit on your bill (via net metering).
  • Off-grid systems are not connected to the electricity grid. They use batteries to store power, so you can use it even during power cuts. These are best for remote areas where grid electricity is not available.

An inverter converts the DC electricity generated by solar panels into AC electricity that can be used by household appliances and fed into the grid.

Yes, but they produce less electricity. Solar panels still work in diffused sunlight, like when it’s cloudy or raining, but instead of generating 100%, they might give 30–50%. So, a 3kW system might produce only 1.5 kW on a cloudy day.

No. Solar panels need sunlight to generate electricity. At night, they don’t work. However, if you have a battery-based or hybrid system, it can store extra electricity made during the day for use at night.

Good-quality solar panels last as long as their supporting structure exists. They come with a 25 to 27-year performance warranty. This means they will still produce around 80% of their original power even after 25 to 27 years.

  • Fixed tilt: Simple and cost-effective; panels remain stationary.
  • Adjustable tilt: Angle can be manually changed seasonally.
  • Tracking systems: Automatically follow the sun’s path for maximum efficiency.
  • Ballasted systems: Use weight instead of roof penetrations; ideal for flat roofs.

Mounting structures hold the solar panels in place at the proper angle and orientation to maximize sunlight exposure. They also protect against wind, rain, and environmental damage.

A solar tracker is a device that moves solar panels to follow the sun’s path throughout the day. This can increase energy output by 10–25% compared to fixed systems.

Yes, the mounting structure supports the solar panels and keeps them at the right angle for maximum generation. A strong, rust-free structure ensures the panels stay secure in all weather conditions and last until no external damage occurs.

Yes. A well-designed system with proper panel layout, wiring, and safety measures will generate more electricity, last longer, and need less
maintenance. Poor design or careless work can lead to frequent problems and lower output.

Evaluate the EPC contractor’s technical expertise, compliance with IEC/IS standards, bankable component brands (Tier-1 panels, certified inverters), and quality assurance protocols. Review their track record, project commissioning timelines, and O&M capabilities. Ensure they offer structural and electrical drawings, warranties, and support for regulatory approvals.

Proper design helps the system generate more electricity by setting the right panel direction, angle, and wiring. It also ensures safety, avoids energy loss, and keeps the system running efficiently for many years.

Solar power optimizers are module-level power electronics (MLPE) that perform individual Maximum Power Point Tracking (MPPT) per panel.
They are small devices connected to each panel. They help every panel work at its best, even if one panel has shade or dust. This improves overall system output and allows panel-wise performance tracking.

Your home is suitable if:

  • You have an open rooftop with good sunlight (at least 4–5 hours a day).
  • The roof is strong and not shaded by trees or nearby buildings.
  • You have a monthly electricity bill of ₹1,000 or more — this makes solar more beneficial.

You need about 100 sq. ft. per 1 kW of solar panels. So, if you want a 3 kW system, you need around 300 sq. ft.
Example:
If your monthly electricity bill is ₹2,500, a 3 kW system is ideal and will require 300 sq. ft. space.

Net metering is a system where extra electricity your solar panels produce is sent back to the power grid. The electricity company gives you credit for this. At the end of the month, your bill shows the net usage (units used – units sent), and you pay only for what you actually use. This can reduce your bill to as low as ₹50–100/month.

On average, 1 kW of solar panels requires 10–12 square meters (100–130 sq. ft) of shadow-free roof or land area.

A professional installer will assess:

  • Roof orientation (south-facing is ideal in India)
  • Tilt angle (for optimal sun exposure)
  • Structural strength
  • Shading from trees or buildings

Yes. Common types include:

  • Sloped/Tiled Roofs: Require specialized hooks.
  • Flat Roofs: Use ballast systems or elevated tilt structures.
  • Metal Roofs: Allow easy mounting with clamps.

In India, you typically need:

  • Approval from the local DISCOM (electricity board)
  • Net metering application
  • Structural safety clearance (if applicable)

In India, the cost of installing a solar system depends on its size and quality of materials. On average, it costs about:

  • ₹60,000 to ₹75,000 per 1 kW (without subsidy)
  • After central government subsidy (PM Surya Ghar Yojana), you can get:
    • ₹30,000 subsidy for 1 kW
    • ₹60,000 for 2 kW
    • ₹78,000 for 3 kW and above

For example: A 3 kW system may cost around ₹2.1 lakh, and after ₹78,000 subsidy, your actual cost is around ₹1.3 lakh.

A 1 kW system generates 4–5.5 units per day, potentially saving ₹1,200– ₹1,800 monthly depending on your local tariff.You can save up to 80–90% on your monthly bill.
Let’s say your monthly electricity bill is ₹3,000:

  • Annual bill = ₹36,000
  • With solar, you can save around ₹30,000/year

So, in 4–5 years, your system pays for itself. After that, electricity is almost free for 20+ more years.

Yes! The PM Surya Ghar Yojana provides central subsidies for home solar installations:

  • ₹30,000 for 1 kW
  • ₹60,000 for 2 kW
  • ₹78,000 for 3 kW or more

You must apply through the official portal:
https://pmsuryaghar.gov.in

This subsidy is credited directly to your bank account after inspection.

The payback period is the time it takes to recover your investment through bill savings.
Usually, it’s between 4 to 6 years.

For example:

  • ₹1.3 lakh investment (3 kW after subsidy)
  • Annual savings: ₹25,000 to ₹30,000
  • You recover cost in 4.5 to 5 years

After that, you get 20+ years of free electricity!

You can:

  • Pay in full upfront
  • Apply for a solar loan from banks like SBI, HDFC, or NBFCs
  • Get EMI options from solar companies

Some government schemes also support low-interest loans under MNRE guidelines.

Yes, many solar companies and banks offer EMI plans. Example:

  • ₹1.5 lakh loan over 5 years
  • EMI around ₹3,000/month

This EMI is often equal to your current electricity bill, so you don’t feel extra pressure.

Yes. A house with solar:

  • Has lower electricity bills
  • Is future-ready
  • Is attractive to eco-conscious buyers
    In India, homes with solar systems are often valued ₹1–3 lakh higher
    in the resale market.

Not exactly zero, but very low.
You still pay:

  • Fixed charges (₹500–₹600/month)
  • Net units consumed from the grid
    But if your system is sized correctly and net metering is active, your
    bill can come down to under ₹100/month.
  • CAPEX: Pay full upfront cost. You own the system.
  • OPEX/RESCO: Pay monthly for power; third-party owns the system.
  • PPA (Power Purchase Agreement): Long-term contract to buy power
    at a fixed rate.

Usually:

  • Site survey: 1 day
  • Installation: 2–5 days depending on system size
  • Net metering approval: 2–4 weeks (varies by state)

In total, the entire process can take 2 to 4 weeks from booking to completion.

Here’s how it works step by step:

  1. Site visit – We check your roof, sun direction, and shadow
  2. Design – We calculate how many panels you need
  3. Quotation & booking – You approve the price
  4. Installation – Panels, inverter, and wiring setup
  5. Inspection by DISCOM – For net metering
  6. System activation

We handle all steps for you, including paperwork.

No. Solar panels are installed on mounting stands that do not damage the roof.
We avoid drilling wherever possible and use proper waterproofing materials if needed. RCC roofs are ideal.

Shading affects performance. During the site visit, we check for shadow from trees, tanks, or buildings.
If your roof isn’t south-facing, we install tilted structures to face panels toward the sun. This helps maintain performance.

No. In fact, panels protect the roof from heat and rain.
We use anti-rust frames and careful installation to avoid cracks or leaks. If drilling is needed, we seal the area to prevent water entry.

Yes. Panels can be dismantled and reinstalled at your new location.
However, you may need new wiring and approvals again. Shifting cost may be ₹10,000 to ₹20,000 depending on distance and size.

  • Monocrystalline (Mono) panels are more efficient, need less space, and work better in low light. They’re also costlier.
  • Polycrystalline (Poly) panels are cheaper, need slightly more space, and have slightly lower efficiency.

In India, Mono PERC panels are becoming more common due to better performance in hot climates.

Charge controllers regulate the current and voltage from solar panels to batteries, preventing overcharging and extending battery lifespan.

Absolutely—solar panels are most efficient when sunlight strikes them perpendicularly. Tilt and orientation adjustments can maximize this efficiency.

It depends on your monthly electricity bill. Here’s a simple guide:

Monthly Bill Recommended Solar Size
         ₹1,000        1 kW
         ₹2,000       2 kW
         ₹3,000       3 kW
         ₹5,000       5 kW

Example: If your bill is ₹3,000/month, you use around 300 units. You need a 3 kW system to cover this.

  • Your inverter shows live generation
  • Most systems come with a mobile app to track daily, monthly, and yearly performance
  • You’ll notice lower bills. We also offer a performance health check if you feel the output islow.

Very little! Just:

  • Clean the panels with water and a soft cloth every 15 days.
  • Check for dust, bird droppings, or leaves.
  • Keep inverters in a cool, dry area
    We also offer Annual Maintenance Contracts (AMC) for hassle-free upkeep.

In most cities, twice a month is enough. In dusty or industrial areas, weekly cleaning gives better performance.
Do not use soap or hard brushes. Just plain water and a soft cloth or wiper.

It can be replaced individually. Panels come with 10–12 years product warranty and 25-year performance warranty.

  • On-grid system: Stops working during power cuts (for safety).
  • Off-grid or hybrid system: Works with battery backup.
    If you want uninterrupted power, go for a hybrid system with battery storage.

The inverter is the heart of the system. It:

  • Converts DC power from panels into AC for home use.
  • Shows performance data
  • Manages flow between panels, battery (if any), and grid

Most inverters work well for 8 to 10 years. They come with a 5–10 year warranty, depending on the brand.
Timely maintenance increases lifespan.

Yes! Batteries help store power for use at night or during power cuts.
You can:
