If you want to know more information about solar system, you can book an engineer visit from our site. Our solar engineer will visit at your location and they will explain it.
What is solar system?
Solar system is a combination of multiple components such as inverter, battery, solar panel and accessories. Solar system is installed to generate electricity.
What are benefits of solar system?
It has many advantages as given below:
- It reduces electricity bills
- It provides continuous power for 24×7
- It reduces pollutions as it generates green energy
- It provide additional source of income to farmers who export this solar energy to grid and earn extra money
- Property value increases by installing solar system on roof
- You get subsidy and incentive from government
- You become owner of your electricity and reduces burden on transmission line
Types of Solar Rooftop Power Systems
A typical rooftop solar power system has electricity-generating photovoltaic panels, commonly known as solar panels, on top of a house or building. But there is much more to it…
On-Grid System or Grid-tied System
These systems are designed to work in conjunction with the grid or simply put your electricity supply. The electricity you generate using this system is fed back to the grid. A net meter is installed along with this system to keep track of the electricity consumed by you versus what you generated and fed back to the grid resulting in savings which gets reflected in the bill. It does not work when the grid is down.
Off-Grid System
These systems store the electricity produced by conversion in batteries and utilise the stored energy by converting it back to AC as and when required. The rising cost of other power sources and the increasing demand of electricity, especially in high power cut or no grid areas, has resulted in increased demand for such systems. The reduction in battery prices over the years has further brought the system cost down.
What is warranty of solar system?
You get 1 year warranty on solar system, and 25 years on solar panel performance, 2 years on inverter and 5 years on solar battery. Even you can extend your warranty period if needed.
Who should buy it?
If you are getting frequent power cut in your home and if you are looking for affordable electricity, solar power system would be suitable for you.
These are some of the customer types who bought this system:
- Hospital owners
- Petrol Pump
- Farmers for Water Pump
- Atta Chaki owners
- School / Colleges
- 2/3 bhk home owners
- Small shop owners
Installation
Lastly, but most importantly the installation of the solar power system needs to be done with precision in order to generate maximum electricity through the solar power plant. No two rooftops are the same therefore the process requires system design and careful supervision to ensure proper installation of the solar rooftop power plant. Solar panels used in any solar power system should be installed facing South direction.
Tilt angle of solar panel should be between 8 to 33 degree in India, but it varies as per the height of the installation. Solar panels must be grouted using anchor bolts or concrete foundation to ensure durability in rough conditions. UPS and batteries must be installed as close to the panels as possible to minimize DC transmission losses. One needs to ensure that the maximum permissible voltage is not exceeded when connecting the panels in series.
There should be a minimum gap of 5 mm between two solar panels to allow for any expansion in materials. The solar panels being interconnected must be of the same type (mono or poly) and same power class. There should be no shade or shadow on the solar panels as this may lead to losses, formation of hotspots, etc.
