SOLAR ENERGY AND PHOTOVOLTAIC SYSTEM: IN DEPTH

Introduction and types of Photovoltaic system 1 lecture 00:00 Types of Photovoltaic system

• A stand alone or an off-grid system is a system which is required to provide power at places where no other sources for providing electricity are available. This is the most popular type of solar PV system. This type of photo voltaic system tend to be less expensive and they tend to be small systems.
• A grid tie system works in a similar manner like a stand alone system except for that any excess power production is fed into the grid for later use. The benefit of grid tie system is that is that it reduces our reliance on electricity companies and more of the electricity is produced in an environment friendly manner.
• A grid-tie with a power backup system is one of the most beneficial system in terms of user effectiveness. It is infact, a grid-tie system with a battery bank for backup. Instead of sending surplus energy to electricity companies excess energy can be stored in battery banks and can be used by users during times of need. This type of system enables users to be self-reliant on electricity generation. Even if there is a power cut electricity still remains available for users to rely on. However the cost of such a system tends to be higher than a standard grid-tie system mainly because battery banks tend to be expensive.
• Lastly, it is the grid fallback or grid fail-over system. It is a type of system in which a solar array generates the requisite power which is then send to charge a battery bank. The energy from battery is then taken and run through an inverter to power household appliances. When the batteries run out of power, the system switches back to the grid power supply. The solar array then again recharges the batteries and the system continues working as usual.

QUIZ 1 QUIZ 1 QUIZ 1 QUIZ 1 Micro-inverters 1 lecture 00:00 Why Micro-inverters? Micro-inverters have started gaining popularity from a recent time. Each solar panel has its own individual inverter in a micro-inverter system, and which converts the output to AC power. In general, each solar panel becomes its own independent solar energy system. There are a lot of benefits associated with micro-inverter systems compared to grid-tie systems as mentioned below: 1. As each solar panel runs as an own individual unit, so, if one panel is under-performing, either due to damage or because it is shaded, it does not affect the output from any of the other panels. 2. Since there is no high voltage DC power running from one panel to the next, safety is less of an issue. 3. Installation, maintenance and finding faults also becomes comparatively easier. 4. Becomes easy to expand grid-tie system in the near future. 5. Solar panel installation becomes easier and more flexible. Quiz 2 Micro-inverters. 1 lecture 00:00 Why Micro-inverters?
