Yes, the Indian government offers subsidies for residential solar installations through various schemes. Currently, subsidies of up to 40% are available for systems up to 3kW and 20% for systems between 3kW to 10kW. Our team will help you with all the paperwork and documentation required to claim these subsidies.

DSMS SOLAR offers flexible EMI options through our financing partners. EMIs start from just ₹2,999 per month with loan tenures ranging from 3 to 5 years. The exact EMI amount depends on the system cost, down payment, and loan tenure. We offer zero down payment options for eligible customers, making solar energy accessible to everyone.

Most residential solar panel systems in Bihar have a payback period of 3-5 years, after which you essentially get free electricity for the next 20+ years. With rising electricity costs, your savings will increase over time. Typically, customers see a 15-20% ROI annually, making solar panels one of the best investments for your home or business.

We offer a 25-year performance warranty on all solar panels, ensuring they maintain at least 80% of their rated output after 25 years. Additionally, there's a 10-year product warranty covering manufacturing defects. Inverters typically come with a 5-10 year warranty depending on the brand, and our installation workmanship is covered for 5 years.

Solar panels require minimal maintenance. We recommend cleaning the panels 3-4 times a year to remove dust and debris, which can be done with water. Our annual maintenance packages include thorough cleaning, system inspection, and performance checks to ensure optimal operation. With no moving parts, solar panels are very reliable and require little attention.

If your solar panels get damaged due to manufacturing defects within the warranty period, they will be replaced free of cost. For damage due to extreme weather conditions, most home insurance policies can be extended to cover solar panels. Our team will assist you with the claim process and ensure quick replacement to minimize downtime.

Yes, DSMS SOLAR provides comprehensive after-sales service including regular maintenance, performance monitoring, troubleshooting, and repairs. Our dedicated support team is available 24/7 to address any concerns. We also offer annual maintenance contracts (AMC) for worry-free operation of your solar system throughout its lifetime.

Most customers see a reduction of 70-90% in their electricity bills after installing solar panels. The exact savings depend on your system size, energy consumption, and local electricity rates. For a typical 5kW system in Bihar, you can expect to save approximately ₹5,000-7,000 per month, which translates to lakhs of rupees over the system's lifetime.

Excess electricity generated by your solar system is fed back to the grid through net metering. Your electricity meter runs backward when you're producing more than you're consuming, giving you credits on your electricity bill. These credits can offset your consumption during evenings or cloudy days when your solar production is lower.

Standard grid-tied solar systems shut down during power cuts for safety reasons. However, we offer hybrid systems with battery backup that can provide power during outages. These systems automatically switch to battery power when the grid goes down, ensuring continuous electricity supply to essential loads in your home or business.

DSMS SOLAR offers monocrystalline, polycrystalline, and bifacial solar panels from premium brands like TATA POWER SOLAR, ADANI SOLAR, WAAREE SOLAR, and LOOM SOLAR. Monocrystalline panels offer higher efficiency but at a higher cost, while polycrystalline panels provide a good balance of cost and performance. We recommend the best option based on your specific requirements and budget.

A 1kW solar system typically requires about 100 square feet (10 square meters) of roof space. For a standard 5kW residential system, you would need approximately 500 square feet of unshaded roof area. During our site survey, we'll assess your available space and design a system that maximizes energy production within your constraints.

Solar panels can be installed on most roof types including concrete, metal, tile, and asphalt shingle roofs. The mounting system is selected based on your specific roof type to ensure secure installation without compromising roof integrity. For flat roofs, we use non-penetrative ballast mounting systems, while pitched roofs typically use rail-based mounting.

Solar panels continue to generate electricity even during cloudy monsoon days, though at reduced efficiency (typically 10-25% of their rated capacity). Our system designs account for seasonal variations to ensure year-round performance. Modern solar panels are also highly durable and waterproof, designed to withstand heavy rain and adverse weather conditions.
