A hybrid system works by using solar PV power during the day – with excess power
used to charge your batteries for later use at night. The major design considerations are
your peak power usage ie the most power you will use at any one point in time and the
amount of power in kWhr that you expect to use during non-solar producing hours.
From point of contact, Nirmitee Solar will help guide you towards the correct type of
system and meet any budget constraints, before undertaking a detailed design and
estimation process. Our engineering and modelling systems will correctly select the
right product combinations and provide detailed electrical and financial modelling. We
will ensure that your hybrid solar system has sufficient autonomy and head room so as
to meet your power needs.
The hybrid solar unit is an additional inverter which takes your solar PV, mains,
batteries and optional generator – combines and stabilises it all into one. If the weather
is black for days on end the system simply switches back to mains power when
required, thereby ensuring consistent power and zero damage to your batteries.
We recommend installing a kW of solar PV for every kWhr you want to store. This rule
of thumb can vary wildly depending on your specific situation, so it is important that if
you are considering hybrid solar that you go through a detailed design process. When
looking at hybrid it is important to maximise PV production and reduce battery use. This
can be achieved by load shifting items such as electric hot water systems and
swimming pools onto daytime usage. Nirmitee Solar can program your hybrid inverter
such that it dumps excess power into these items thereby ensuring that you’re
maximising your investment. Further reductions may be achieved by recommending
appliance changes such as LED lighting and other high-efficiency products. All of our
advice is accompanied by detailed financial modelling showing items such as return on
investment and payback periods.
We provide a range of customized Off grid solar PV installation from concept and
design to commissioning for residential and commercial application. These installations
can be designed based on the need of the customer and installed at site by out experts.
The scope will include system design, engineering, plant layout, supply of component,
system integration, installation, commissioning and maintenance.
Solar PV based off grid power plant consists of PV array which generates DC electricity
from sunlight, a battery bank to store the DC energy and an inverter to convert from DC
to utility grave AC electricity. These plants are available in two configurations a "Hybrid"
that uses diesel generator/Mains to supplement battery charging, and a "Stand Alone"
without a generator. Custom configurations for specific voltage or power requirements
are available for a reliable power source in any remote application
