1How do I know what system size I need?

For starters, our assistance will make this very easy for you as we will give you all the needed information. A team of installers will come down and complete a site survey to give a proper estimate. The solar system size will be based on the total number of kilowatt-hours your establishment used in the last 12 months.

2How much space do I need for a solar photovoltaic system?

In bright sunlight, a square foot of a conventional photovoltaic panel will yield 10 watts of power. That’s a helpful rule of thumb for calculating a rough estimate of how much area you might need. For example, a 1000 watt system may need 100 – 200 square feet of area, depending on the type of PV module used.

3What are the benefits available to reduce my solar installation cost?

There are numerous economic benefits of investing in a solar power plant such as 80% accelerated depreciation, Viability Gap funding (VGF), 10 years income tax holiday and various other ROI attractions relating to investments in solar projects, incentives that have been introduced by Government of India, that means you could recover your investment through tax savings in approximately 3 years –an IRR that could be as high as 30%. We can further elucidate the benefits of investing in solar, such as Tax savings, Renewable Energy Certificates (RECs) and power purchase agreements, across the country with a one-on-one meeting with you.

4What role does panel efficiency play in energy production?

Efficiency of panels as a selling point can often be misleading, as efficiency plays no role in producing more power. A 200W 10% efficient panel and a 200W 40% efficient panel both produce the same rated 200W. In this case the 40% efficient panel would just create the same amount of power over a smaller area. Efficiency only reflects the physical size of a module & the price at which it would cost. The efficiency of a solar panel is the percentage of the solar energy to which the panel is exposed to that is converted into electrical energy.

5What do the terms on-grid, grid-connected, grid-tied and off-grid mean?

On-grid, grid-connected, and grid-tied all mean that your system is connected, or tied in to the utility electrical grid. The typical solar electric system is designed as an on-grid system, meaning that it is interconnected with your existing utility service. Off-grid refers to systems that are not connected to and are independent from the utility electrical grid. These types of systems require a series of battery back-up sources to store electricity for night time use. These systems are typically tend to be more expensive.

6What is net-metering?

This is a method of measuring the difference between the energy you purchase from your utility company and energy you generate and feed to the grid. Solar energy fed to the grid spins the meter backwards, thereby finally giving a net figure of usage from the grid.

7How will the weather affect my solar system?

Solar electric systems are designed to withstand extreme weather conditions. Such as extreme temperatures, lightning, winds up to 80 mph and snow are all conditions the system can handle.

8How strong are the solar panels?

Our panels are certified by ETL to meet UL 1703 standards and are fully tested to withstand wind, hail, sleet and snow.

9Do your solar panels have a warranty?

Our product is durable and has a lifetime of 25 years backed with a warranty. We guarantee our customer will receive 100% of the panel’s rated power at the time of purchase.

10What if I need to replace my roof?

In most cases the solar system can be easily removed and reinstalled on your new roof.

11If I move, can I take my solar system?

You can certainly take your solar system with you however it’s likely better to leave it. Solar panels increase the resale value of the property.

12What is the maintenance required for the PV panels?

PV panels are virtually maintenance free, all they need is to be cleaned. However this is mostly done by the rain. If necessary you can even hose the modules down. Wash them in the morning or evening when they are not hot to prevent thermal shock.

13Will my system work at night?

No, it will not. Sunlight must be present in order for your solar modules to produce power. During the night you would be drawing power from your current utility company.

14Will my system work on cloudy days?

Yes, though it will produce less electricity than on a perfectly sunny day. Think of it as a cloudy day that you go to the beach. You think it is for some odd reason a good idea not to put sunscreen on. You then, however, end up getting extremely burnt. This is because even though it may not be visible, the sun is still producing UV rays through the clouds. This energy is captured by your solar panels and turned into electricity.

15What happens during a power outage?

Unless you have an off-grid battery back-up supply or a hybrid system installed then you will not be receiving power along with everyone else. The utility company will actually stop pulling power from your system back to the grid to ensure the safety of any electrician that may be working on the power lines. A backup generator is another great alternative to have installed for the case of emergency power. Navitas Solar can also supply and install both commercial and residential back-up generator systems to suit your needs.

16How much maintenance do solar energy panels require?

Solar photovoltaic panels require little maintenance – no need to wash or dust. It is, however, important to place panels where they will remain clear of shade and debris. Thus you will have to wipe them off if too much snow or leaves fall on them. Solar hot water collection arrays don’t need much attention either. It does help to periodically use a window wash brush, biodegradable soap, and water to clean the tubes.

17What are the environmental benefits?

The major benefits of using a solar system are the reduction of waste, higher efficiency usage of electricity, conservation of fossil fuels and reduction of pollutants.
