    24-72 hours is turn around time for any fault response. we also have customer hotline service to support customers to log service calls.

    FIMER inverters have semi-conductor fast acting fuses on AC & DC side to protect inverter from SC and AC breaker to trip and isolate inverter during fault conditions.

    Typically in Indian conditions, you can expect panels equivalent to 1kW  to generate between 4-5 units per day on average, when taken for the full year.

    Typically in Indian conditions, you can expect panels equivalent to 1kW  to generate between 4-5 units per day on average, when taken for the full year. There are periods when generation will be much higher, like the February to June period. Similarly, in North India, generation during November to January end would be much lower due to pollution, shorter days. In the early summer phase and summers, with clear skies, for every  kW capacity, you can get over 5, even 6 units in a day.

    To answer your question then, if you go with the new mono panels available today, they would typically be in the 540 Watt range, You would thus need about 6 of those to be sure of getting 350 units per month on average, or 4200 units annually. Bifacial panels will deliver even higher output, at a higher initial cost of course.

    Better to go with white paint to increase albedo sensitivity, which will increase the yield.

    Majority of Indian solar firms offer a 25-year warranty on their products. If regular maintenance is done, the product life increases considerably. Within the system, inverter warranty might be 5-8 years, and the installer itself would provide a separate 5 year maintainance and running commitment. Other than the module and inverters, the other systems can be expected to last the full 25 year period with regular checks.

    Yes, Mounted solar panels are available in the market and are being used widely. BIPV (Building Integrated PV) for instance refers to panels that are used as substitutes for windows. Similarly, solar panels are being used on balcony’s now, besides for fencing as a solar fence. These options, while not optimum in terms of generation, do help to provide you with a solar energy source in well irradiated areas.

    Solar panels work at full efficiency at around 25˚C. So even in winter they work fine. Even at lower temperatures, they typically perform well if sunshine is good. Colder regions, with their lesser issues of dust are also beneficial for solar generation. Remember, solar energy is generated by light falling on solar panels, not by heat. So really hot temperatures offer no benefit to users.

    Generally, rooftop solar offers an ROI of over at least 20% in most markets today. Hence, it gives a payback period of about 4-5 years. Even without any subsidy or incentives, chances are, it will pay back your investment in 7 years or less with good maintenance and a net metering regime.
