In January 2016, HFE was given the challenging task of installing rooftop solar panels on the building of the National Institute of Solar Energy, which is also the headquarters of the Indian Solar Alliance. Given the specifications and design of the rooftop, it proved to be a particularly taxing project as the building had an elliptical roof and the modules had to be installed along the periphery of the ellipse on top of the mesh-like structure protruding from the building.
HFE overcame these challenges through an innovative design, which required each module to be uniquely positioned in order to optimise generation. In addition, since the building stands 20 metres tall, the wind speeds on the rooftop are usually high and could knock down installations. The clamps used in the project, therefore, were specially designed to hold the modules in place. Moreover the project was to be executed within a stringent timeline of around 30 days. However, HFE commissioned it in a record time of only 20 days.
A PV system consists of different components, including:
- Solar Modules (group of solar cells)
- Charge Controllers (to control the amount of charge going into the inverter)
- Inverters (to convert the direct current (DC) of a PV system into alternating current (AC) for use in electrical appliances)
- Batteries (to store any excess energy and use it when the PV system is not generating power) (for off-grid and hybrid systems only)
- Racking (mounting hardware for the modules) etc.
Going solar will help you in the following ways:
- Save Money: Solar power is often cheaper than your grid electricity. There is also no peak time “demand” charge associated with solar electricity. If you own the rooftop system, you will have access to free electricity after a certain time period – i.e. once the initial cost of the system is amortised. [refer (c)].
- Lock In Your Energy Costs: As fossil fuel stocks deplete, the costs of grid based electricity (generated using fossil fuels) will continue to rise. Going solar allows you to locked-in your energy costs for the lifetime of the system, typically a period of 25 years or more.
- It Makes Perfect Business Sense: Depending on your electricity consumption and the incentives and/or rebates available in your area, your rooftop solar system could pay back for itself in as little as 4-5 years. Since the systems last for as long as 25-40 years, you will have access to free electricity for many years.
- Improves Your Business’ Public Perception: Solar systems are an emissions free source of electricity generation. Therefore going solar also has huge environmental benefits. This will improve the perception of your business in the eyes of your customers, your employees, the community and even the government. It’s great CSR.
