Going solar in itself is one of the biggest investment opportunity you grab in your life.
To get the best out of this opportunity, you must pick the best rooftop solar system for yourself. But how do you do it?
Well, here is a checklist that ZunRoof recommends you tick off before you finally install the solar system at your home.
Choose Only From Certified Solar Panels
Go only for MNRE approved tier-I solar panels. There is a large selection of solar panels available in the market for purchase. I would suggest that you choose NOT to skimp on quality when picking your solar panels. Your average solar panel should last at least 25 years and still give up to 80% efficiency by that time. Low-quality solar panels will cost you dearly on the long run in terms of durability and efficiency as time passes.
Check for Rebates or Subsidies Available in Your State
Many state governments have put out some amazing incentives to push residents to take up renewable energy sources. Check-in on the subsidies or rebates your local government is providing on Rooftop Solar Systems and solar panels. Some states in India tend to offer up to 40% subsidy on choosing to go solar!
Have a Thorough Site Assessment Done of Your Roof
Your return on investments and efficiency will drop significantly if you do not get the right inclination, positioning, or space to put up your solar panels. Have an expert do shadow profiling and design the perfect system layout for you before you splash on a solar panel which just doesn’t absorb any energy from the sun.
Select a System Size That Best Meets Your Energy Demands
Do not overdo it on the number of solar panels that you want to purchase. It will take you way too many years to break even if your power consumption is below your solar energy supply and the system will have been too expensive to be beneficial. Use the ZunRoof Solar Calculator to know what size your system should be to save on money.
Go for Polycrystalline Solar Panels Instead of Monocrystalline Solar Panels
Monocrystalline solar panels tend to have an efficiency of 20-21% and take up only 75-80 sq ft of space per kW but they can be quite expensive. You can choose to skip that and go for polycrystalline solar panels. They have an efficiency of 16-17% and take up 100 sq ft per kW. Though they are less efficient, they are still much more cost-effective at producing the same amount of power and you will get your return on investment much earlier.
Now taking all these steps would require you to go to different vendors and organisations. Instead of spending months going back and forth, you can hire companies like ZunRoof to be your single contact point to get a residential Rooftop Solar System instead of dealing with various vendors.
