How does a PV solar system work?
- A photovoltaic (PV) solar installation consists of solar panels, mounting structures for panels on the roof, electrical wiring, and an inverter.
From sunrise to sunset, the solar panels generate direct current (DC) electricity which is sent to the inverter. The inverter converts the DC into alternating current (AC), which is the type of electricity required for household use.
Is my roof suitable for solar?
Yes, if you have roof space to install solar panels with 4-5 hours of sunlight almost daily, you should consider getting a rooftop PV solar system and start saving.
But there are a lot of other things that affect how well-suited your roof is for solar, including the location of your property, the angle of your roof, how much sun/ shade it gets throughout the day, any adjacent structures, and how old your house/ property is?
Our solar advisors can help you determine if your roof is a good fit for solar.

How many solar panels will I need for my energy requirements?
While determining the number of solar panels you will need;
You have to first consider your energy consumption (check your electricity bills) to find out your energy requirements.
Know the shadow-free area available for installation, beacuse that will determine what size of installation is possible in your premises.
How much will I save with a solar system?
An on-grid system starts paying for themselves almost immediately. The amount of saving can vary based on several factors like:
System size and performance
Your average energy usage
Any applicable solar credits or Tax benefits, and
Utility tariff-rates for net metering offered by the electricity provider.
A detailed calculation of your potential return on investment (ROI) will be provided by us during your solar evaluation.
Can solar panels increase the value of my home?
Installing a home solar system can increase the value of your home considerably and make it more appealing to potential buyers.
Do solar panels work on a rainy / cloudy day?
Solar panels are capable of producing electricity in all types of weather, year round. Though the amount of power produced does change with the season, you can notice some daily variations as well. Your Solar energy generation can vary somewhere around 70% to 90% due to cloud movements.
During monsoons, the movement of the clouds is more frequent and the power output varies around 40% to 80% of your average monthly generation.
We design the systems with all four seasons in mind, and this seasonal fluctuation will be factored into your solar production estimate. During your solar site assessment, we take in to account the sunlight that your specific region receives each year. This means that your system will be sized appropriately for the amount of sunny (or cloudy) days you receive annually.
Will trees/ shade impact my solar performance?
Solar panels provide best output under direct sunlight and shade on your solar panels decreases their efficiency. When we design your system, we account for existing shade on your roof, but changes in tree shape or height can increase shade and lead to decreased production over time.
You don't have to hack down the trees. But when you decide to go solar, it is best to keep your trees trimmed, so they do not block the sun from shining on your panels.
You can learn more about the other factors affecting your solar power generation.
Will my solar system still work well after 25 years?
The solar panels on your roof should continue to produce electricity well past the 25 year mark. Like any other equipment that you use their efficiency might decrease over time, but investing in quality products will help you to earn more on your investment.
Good products available in the market offer long-lasting panels with average degradation rate as low as 0.67% per year.
Which means that even after 25 years, your system should be operating nearly at 80% of its original capacity and continue providing you with clean, renewable energy.
What if my solar panels don't produce enough power?
At times, your personal energy consumption may differ due to an unseasonably hot summer needing you to run the air conditioning more than usual. If that’s the case, you may have to use some extra electricity from your local utility, resulting in a slightly higher energy bill for that month. Your solar panels would still produce the amount of power they’re supposed to. Your higher-than-average energy usage will just need an added boost from the grid to support it.
To know more, you can read about the factors affecting solar energy generation.
Why do I still receive a utility bill with solar?
You receive a bill from the utility even with solar because you remain connected to the grid.
Even in months where your solar system provides all of the electricity you need, you can expect to pay standard utility connection fees, known as the "Fixed charges" on your electricity bill.
Being connected to the grid is a good thing. It allows you to have power when you are using more than your system can produce like when you're running your air conditioning during an extremely hot day. It also allows you to take advantage of net metering by exporting excess energy to the grid, so your solar power never goes to waste and you can have credits for later use.
What is net metering?
Net metering means that your utility will keep track of the solar power that you send into the grid (with the help of a bi-directional meter/ Net-meter) when you are producing more than you’re using. In some months, you may earn credits for this extra power while in others you will need to buy grid power to meet the energy demands of your home.
How long does it take to get the installation done?
The process of having the solar system installed on your roof can be relatively quick — many installations are completed in two to three days.
But before our crew comes to your house, it takes a few weeks to prepare your project so that you have the smoothest installation day possible. Whenever possible, we’ll do the work for you, and we’ll keep you updated along the way.
Here’s what we do:
Conduct a site survey to look at your roof and electrical panel
Finalize your design requirements
Apply for permits and get necessary approvals
Complete your installation
When its time to install the system, we’ll let you know how long the construction process will take for your property and if you need to do anything to prepare towards it.
Can solar power work without batteries?
Solar power installations come different configurations.
They could be net-metered with the electric company (also known as on-grid). In this case the system can work without any external batteries connected to it.
Second configuration could be an off-grid solar in which case, we can set up a stand-alone plant in places where grid facility is unavailable. Here, you will need batteries to store energy for night-time use or during unfavourable weather conditions like monsoon season.
How is solar energy different from electricity supplied by the local utility?
Energy from the local utilities comes from power stations set up hundreds of kilometres away. It goes through multiple transmission and distribution setup before reaching your home, including transmission lines and distribution substations resulting in losses. Maintenance of such huge infratructure involves cost whch is billed to the end-consumer, making it costlier.
What is a solar site assessment?
Do the panels operate during power outages?
It will basically depend on the type of installation;
How much does a solar panel weigh and how big are solar panels?
The average solar panel available on the market weighs 21-23 KGs and is approximately 77 x 39 x 1.4 inches big.
How many watts per hour will my panels produce?
There are many factors that affect the production of a solar panel (Location, orientation, tilt, weather, shade, etc.). Solar panels produce varying amounts of energy through the day. In the mornings and evenings, when the sun is low in the sky, solar panels will generate less power compared to in the afternoons when they are receiving direct sun exposure.
What is the warranty on a solar system and how long will it last?
Our warranty accompanies worksmanship that shall be free from material defects for 5 years, the system's solar panels carry a 25-year linear performance warranty, and inverters carry minimum 5-year manufacturers' warranties.
Can I receive a credit for my extra energy production?
Depending on the net metering laws and electricity provider in your state, excess energy generated may roll over as a credit towards the next month’s bill (credited on an annual basis), or paid to customers as a refund at the end of annual billing cycle.
Aren't Solar Panels Expensive?
What kinds of equipments can solar handle? Can solar run heavy loads like ACs or geyser?
With a solar PV system you can power anything that needs electricity to operate. The only consideration is that the inverter needs to be sized accordingly so that you get ample backup (hours) in case of energy storage/ batteries. During your solar assessment our solar advisors will help in properly sizing a system with detailed load calculation.
