Frequently Asked Questions

Yes, it is. Solar energy is void of producing environmentally hazardous conditions unlike nuclear energy or hydro energy because solar panel systems have no moving parts, have earthing mechanism along with a glass sheet as cover, and don’t require abnormal conditions to function. In fact, it is the most reliable and efficient form of renewable energy for households and businesses alike.

Solar Panels work on the principle of photo-voltaic effect (PV effect). Basically, when light energy hits the solar panel surface, the solar cells start conducting electricity due to the photo-electric property of semiconductors like silicon that make up a solar cell.

Solar Rooftop System consists of solar panels that are mounted up on your roof/terrace, unlike traditional Solar Systems which required extra land for setup. This reduces costs and increases utilization of space on your roof/terrace.

There exist three main types of Solar Rooftop Systems-

1. On-Grid Rooftop Systems - These systems are connected to the main power grid and sends excess power back to the grid. Hence, they don’t require batteries to store power. This system is recommended for those looking to reduce their monthly bill, situated in places with low frequency of power outages and want to make money from the sun.
2. Off-Grid Rooftop System - These systems require batteries to store energy for later use as they are not connected to the main grid. They are best suited for areas where grid connectivity is bleak. Consequently, they are costlier than their On-Grid counterpart because of the inclusion of batteries.
3. Hybrid Systems - They are grid connected and also consist of batteries to store power. Obviously, they are the costliest of the three and are considered a luxury option as they encompass both On-Grid and Off-Grid’s core competencies.

If you want a detailed report, you can visit our Savings Calculator page to get exact information on “my solar requirement”, based on your specific details. If you want to check the feasibility of solar at your home and calculate your savings per month as per that, feel free to book a site assessment and one of our site engineers will arrive at your premises for conducting the same.

No, they are not. Good quality solar panels, like the ones used by Zunroof, are angled sturdily, are water resistant, and do not have any moving parts. This gives them the ability to withstand external pressures of all sorts, ranging from wind, dust, and rain to even monkey menace and more. Improper installation, extreme pressure or lack of care given to solar panels, however, may result in them losing this immunity, so best advice is to give good and regular maintenance.

This is a popular myth. Solar panels function on the principle of light energy being converted to electrical energy. Therefore, as long as there is sunlight, high quality Solar panels can ensure up to 75% of peak electricity production even on the cloudiest days of winter / monsoon months.

Only On-Grid Solar Systems don’t produce electricity during power cuts from the grid because of their half-dependency on the main power grid . Off-Grid Solar Systems and Hybrid Solar Systems, however, can produce electricity even during power cuts by virtue of batteries.

Yes, you can. As a matter of fact, not only can you run your entire house completely on solar, you can also expect optimum performance of load-heavy appliances like Air Conditioners, geysers, etc.

Make sure to clean your panels ideally in the night as there is no incident light that can cause the panels to start conducting electricity. You can clean them using a wet cloth on a dry day, or a water hose, to ensure dirt is removed but the moisture is not sticking around on the panels. How often you clean the system depends on the season. You may need to clean more often during the summer months when there is more dust in the air and fewer rain showers to rinse the panels clean. However, do not attempt to clean the wiring underneath the panels.

Yes , it is possible to get loans from banks but quite difficult for large- scale and small-scale solar projects. If you take a loan from bank the rate of interest will be in between 10-13% but Zunroof provides loans at 11.99%. Moreover, 4% cash back is given by Zunroof after 1 year.

Saur Renewable Power caps the interest rate at 10.99%. If our partner charges more for the loan, we give the difference in interest amount as cashback.

Loan tenure is fixed at 1 year.

There is no collateral required at all.

The answer depends on a number of factors like grid type, system size, specifications of the system, your electricity consumption pattern, etc. When you schedule a solar site assessment, our engineers visit your premises, they evaluate the feasibility of solar power system on your rooftop by analyzing a number of engineering parameters like shadow profiling, design 3D-structure layouts, etc. to determine the most optimized system size at the best price for you.

No, Good quality solar panels, like the ones used by Saur Renewable Power, are angled sturdily, are water resistant, and do not have any moving parts. This gives them the ability to withstand external pressures of all sorts, ranging from wind, dust, and rain to even monkey menace and more. Improper installation, extreme pressure or lack of care given to solar panels, however, may result in them losing this immunity, so the best advice is keep an AMC plan to keep them in best condition.
