Each and every summer, the main cities in India like Delhi, Chennai, Hyderabad, etc face power shortage. Power production using coal is the main source of power in India which is slowly being replaced with more natural methods. Alternative source of energy like Wind power, hydropower, sunlight solar panels, nuclear power generation are slowly growing up both technically and also production-wise. Solar panel is the only source that has now become available for retail households. Though expensive it is still catching up with general public and even commercial establishments have started to engage with solar power. Now let us look into some of the important parameters and aspect about solar panels that you should know.
First, you need to check whether installing a solar panel is feasible both technically and also efficiency-wise. For technical feasibility, your roof should have direct contact with the sunlight. If your house is surrounded by taller buildings or trees, then sunlight might be blocked on your roof. That being the case, installing a solar panel will not be a suitable solution. So make sure you have good direct contact with sunlight.
If your roof is inclined, make sure it is inclined towards South-west or South-eastern direction to get the maximum impact of sunlight.
Types of Solar Panels
There are basically two types of solar panel for residential purposes namely
- Photovoltaic cells which convert sunlight into electricity
- Thermal type which uses sunlight to heat water or air
If you are buying solar panels mainly for the purpose of water heater then going for the second option is a sensible thing to do. If you are installing solar panels for general electricity, then use the first option.
This is the most important and crucial part of installing the solar panels. Both the central government and also most of the state governments provides subsidies for installing solar panels at home. In order to qualify for these subsidies and special benefits schemes, you need to hire an accredited installer. He might charge you a bit extra but it is definitely worth it.
This is one aspect which will determine your return on investment. Solar Panels are an expensive one-time investment and you will reap the benefits over a long period of time. Most of the solar panels in the market today have an efficiency ratio of 15%-22%. You need to check the efficiency of the cells provided by your installer and make sure you get the best value for your money.
Government Grants and Benefits
The Central government of India and most of the state governments offer various schemes that encourage people to install solar panels at home. You should first go through them and understand it before starting the installation. You might choose the type and installer based on the scheme that you are eligible for. Do not hire someone before reading about the benefit schemes for solar panels.
