General
Sunny Solar Synergies designs and installs solar panel systems for homes, housing societies and businesses. With a relentless commitment to innovation and excellence, we're driving the Har Ghar Solar mission forward, one rooftop at a time. Established by passionate solar enthusiasts, Sunny Solar Synergies is India's trusted residential solar company. We believe in the power of solar to not only reduce carbon footprints but also to revolutionize the way we power our homes and businesses.
A solar rooftop system is a combination of many components that convert sunlight into usable electricity. The components of a rooftop solar include: Solar panels with PV cells, Solar inverter, Solar panel mounting structures, AC and DC cables, AC combiner box, DC combiner box, Earthing cables, and MC4 connectors. These components work together to capture sunlight and convert it into electricity that can power your home or business.
A solar rooftop system works on the concept of conversion of sunlight into electricity. The phenomenon is known as the photovoltaic effect. When sunlight falls on the PV cells in a solar panel, the sunlight is converted into electricity. The generated power is DC current. An inverter is used to convert that DC power into usable AC power. The generated AC electricity is fed into a bidirectional meter that supplies power to the house. It also exports excess power to the DISCOM (grid) and imports power from the grid if electricity generated by the rooftop solar system is not enough to cover the daily requirement.
If you want to save money from the sun, Solar is the best investment for you. Solar allows you to save on your monthly electric bills plus it also allows you to save the planet by going green. Solar energy is a true form of renewable clean energy which leads to zero pollution (air, noise, land) and emits no greenhouse gases mitigating climate change. Additionally, solar systems have a payback period of 5-7 years and continue generating free electricity for 25+ years.
Yes. The electricity produced by a solar power system is no different than the electricity you get from your electricity distribution company. The only difference is the source. Moreover, it is among the safest source of electricity consumption because it is neither hazardous nor does it release any toxic or harmful gases during production. All our installations follow strict safety standards and are certified for quality and safety.
Under the DBT scheme, the subsidy application process has become much easier. Here's a step-by-step breakdown: Visit the National Portal for Rooftop Solar website. Download the Sandes app from the website and install it. Register as a customer on the Sandes app. Once registered, a discom official will visit your home to assess technical feasibility. After receiving the No Objection Certificate (NOC) from the official, choose Sunny Solar Synergies as your solar installation company. Discuss the project details with us and sign an agreement. Upon receiving payment, we will commence the installation process. We will then provide a work completion report and apply for a net meter installation on your behalf. You will receive a commissioning certificate upon completion. Submit your bank account information and upload a copy of a cancelled cheque through the National Portal for Rooftop Solar. Once the fund handling agency receives your details, the subsidy will be credited to your bank account within 30 days.
Solar Maintenance
Solar panels require minimal maintenance. We recommend cleaning them 2-4 times a year, depending on your location and environmental conditions. Dust, bird droppings, and leaves can reduce efficiency. We offer a free 5-year annual maintenance contract that includes quarterly cleaning, preventive and corrective maintenance, and monitoring of power generation efficiency. Regular maintenance ensures your system operates at peak performance for 25+ years.
Yes, solar panels do work during cloudy days and monsoon, though at reduced efficiency. Modern solar panels can generate electricity even in diffused sunlight. On cloudy days, panels typically produce 10-25% of their rated capacity. During monsoon, the efficiency depends on cloud density. However, the net metering system ensures you can draw power from the grid when solar generation is low, and export excess power when generation is high, maintaining consistent power supply throughout the year.
For on-grid solar systems, if there is a power cut, the solar system automatically shuts down for safety reasons (anti-islanding protection). This is a safety feature to protect utility workers. However, if you have an off-grid system with battery backup, you can continue using solar power during grid outages. For uninterrupted power during outages, you can opt for a hybrid system that combines grid connection with battery storage.
Our solar panels come with a comprehensive warranty package: Performance Warranty: 25 years with guaranteed 80% efficiency after 25 years. Product Warranty: 10-12 years covering manufacturing defects. Inverter Warranty: 5-10 years depending on the brand. We also provide installation warranty covering workmanship and mounting structures. Our maintenance contract ensures your system operates optimally throughout its lifespan.
Solar Economics
The cost of solar systems varies based on capacity and quality. Here's a reference about the range of solar panels for home cost without a subsidy in India: 2 kW rooftop solar system: ₹1,51,000 to ₹2,28,000, 3 kW rooftop solar system: ₹1,92,000 to ₹2,63,000, 4 kW rooftop solar system: ₹2,40,000 to ₹3,19,000, 5 kW rooftop solar system: ₹2,87,000 to ₹4,14,000, 7 kW rooftop solar system: ₹4,21,000 to ₹5,39,000, 10 kW rooftop solar system: ₹5,59,000 to ₹7,08,000. These prices include installation, net meter, and all necessary components. With government subsidies, you can save 20-40% on these costs.
Most homeowners save 80-90% on their monthly electricity bills. For example, if your monthly bill is ₹5,000, you could reduce it to ₹500-1,000 per month. Over 25 years, this translates to savings of ₹12-15 lakhs or more, depending on your current consumption and electricity rates. The payback period is typically 5-7 years, after which you enjoy free electricity for the remaining 18-20 years of the system's life.
Yes, we offer multiple financing options to make solar affordable: 10-minute hassle-free loan approval through our partner banks. Interest-free EMI for the first 6 months. 5-year EMI plans with 60 easy installments. Flexible down payment options starting from 10%. We work with leading banks and NBFCs to provide competitive interest rates. Our team will help you choose the best financing option based on your financial situation.
The payback period for a solar system typically ranges from 5-7 years, depending on your electricity consumption, current tariff rates, and system size. After the payback period, you enjoy free electricity for the remaining 18-20 years of the system's warranty period. With government subsidies and tax benefits, the payback period can be reduced further. Our team will provide a detailed financial analysis showing your specific payback period and lifetime savings.
After installing a solar system, you will still receive an electricity bill, but it will be significantly reduced. With net metering, you only pay for the net electricity consumed (imported from grid minus exported to grid). Most customers see 80-90% reduction in their bills. During months when you export more than you consume, you may receive credits that can be carried forward to future bills. In ideal conditions with proper system sizing, some customers achieve near-zero or zero electricity bills.
Installation
The installation time depends on the system size and complexity. For a typical residential system (3-5 kW), installation takes 2-3 days. This includes: Day 1: Site preparation, mounting structure installation, and panel mounting. Day 2: Electrical connections, inverter installation, and net meter connection. Day 3: Testing, commissioning, and handover. For larger systems (10 kW+), it may take 5-7 days. We ensure minimal disruption to your daily routine and complete the installation efficiently.
Our installation process follows these steps: 1. Free site inspection and 3D design (within 24-48 hours of inquiry). 2. Detailed proposal with system design, cost breakdown, and savings projection. 3. Agreement signing and payment. 4. Material procurement and scheduling. 5. Installation by certified technicians (2-3 days). 6. Net meter installation coordination with DISCOM. 7. System testing and commissioning. 8. Handover with user manual and warranty documents. 9. Subsidy application support (if applicable). Throughout the process, we keep you informed and ensure transparency.
While it's not mandatory, we recommend being available during key stages like site inspection, final connections, and commissioning. Our team is professional and can work independently, but your presence helps ensure everything meets your expectations. Many of our customers are working professionals, and we've successfully completed installations even when customers weren't present. We provide regular updates via phone calls and photos throughout the installation process.
