We at TES, understand the potential of energy savings in rooftop building, with our customized
design we make it possible that every sunray is captured and used properly. A solar rooftop system
is installing solar panels in the roof of any residential, institutional, social, Government, commercial,
industrial buildings, etc. A Rooftop installation of a Solar Plant helps in cutting down electricity bills.
It supplies electricity to buildings, so they need to buy less electricity thereby saving on energy costs.
VARIOUS TYPES OF ROOFTOP SOLAR PANELS ARE
- Solar Rooftop System with Storage Facility using battery
- Grid Connected Solar Rooftop System
What is a Solar Rooftop System with Storage Facility using the battery ?
A Solar Rooftop system, having a storage facility is a process of storing the solar in a battery which
can be used later in the night or during times when there is no sun. It is an assembly of many solar panels called a solar
array which is connected to a battery bank that acts as stores these powers and acts as a backup during those times of need.
What is a Grid Connected Solar Rooftop System ?
In a Grid Connected Rooftop also called as Small SPV system, the DC power generated from the SPV
panel is converted to AC power using a power conditioning unit/Inverter is fuelled to the grid either
to a 440/220 Volt three/single phase line or to a 33 kV/11 kV three-phase lines depending on the
capacity of the system installed at residential, institution/commercial establishment and the
regulatory framework specified for respective States.
These systems generate power during the daytime which is utilized by powering captive loads and
feed excess power to the grid as long as the grid is available. In case, where solar power is not
sufficient due to cloud cover etc., the captive loads are served by drawing balance power from the grid.
What Model can be implemented ?
Net metering is a billing process that adds the solar energy system owners for the electricity they
add to the grid. The grid-connected rooftop system works on a net metering basis wherein the
beneficiary pays based on the net meter readings. We can also install two meters, to measure the
export and import of power separately. A Mutual Agreed Tariff can be adopted for gross metering also.
Points to be considered before the installation of a Solar Panel
Based on the Location we can decide to go for an Off-grid or an On-Grid. In locations, where you
have long electricity cuts, an Off-Grid with Battery is a perfect choice. When you go for an off-grid lot
of parameters are checked like
- How long you are going to use
- What are the instruments that to be used
Based on these inputs the Solar PV System can be customized according to the needs of the
customers and to decide on an On-Grid Solar PV System installation, the capacity of the house
has to be calculated to arrive at whether to install On-Grid or an Off-Grid in your house. For
example, you have 2 AC's runs means u 8 + 8 units' means 4-kilo watts capacity you spend
