India is achieving total power
sufficiency in the coming year. And yet, there continue to be the outages of
power that keeps everyone scrambling for the UPS units. These UPS units have
the power to keep them going even when the power supply is down. Yet some
others are setting up their own solar grid to connect to their UPS so they
become independent of the normal power supply.
Check for the Top UPS Supplier
The first step to achieving the solar
grid is to buy the solar panels. To buy small solar panel online India has many stores. The growth rate of the UPS market in
India remains projected at 12% for the five years 2013-18. Search for the top
UPS supplier in India and you will find the list of the best suppliers. You can
depend on them because many of them have won export awards in the past decade.
Choose only those with at least 20-25 years of experience in this field.
Different Kinds of Solar Panels
You
can use many different combinations for getting the power you need. So, it is
possible to make a 4 kW solar panel system with 20 200-Watt or 16 250-Watt
panels. The output of the solar panel depends on the type of panel you choose.
●
Monocrystalline solar panels
●
Polycrystalline solar panels
●
Thin-film solar cells
●
Amorphous silicon solar cells
●
Bio-Hybrid solar cells
●
Concentrated PV cells
The
efficiency is the most for the Concentrated PV cells. These show a conversion
rate of almost 41% as compared to the 20% of the Monocrystalline solar panels
that come next. The other two have low costs due to their lower efficiencies.
The Polycrystalline has 15% efficiency while the Thin-film solar cells have
7-8% efficiency.
Contact the Solar Panel Supplier
If
you have any more doubts, visit the website of the supplier of the solar panel online. You can see all the
specifications there. You can contact them through the help section to clarify
your doubts. They will tell you which is the best solar panel to buy as per
your energy needs.
Find the Number of Panels Needed
You
will need 100 square feet area for putting up solar panels to produce 1 kW of
power. This will on an average produce 1650-1750 kWh of electricity in one
year. That is about 143-153 kWh of electricity per month. A typical house with
5-6 light bulbs, computer, fans, TV, refrigerator, and all will need 9.56 kWh
for one day.
By
eliminating the standby power support to only the appliances we need, the power
need will come to 1.8 kWh or say 2 kWh. Divide this by the insolation (assume
it to be 4 kWh/m²) and multiplying it by the safety margin of 34%, we get this
to be 2x1.34/4 = 0.67 W.
Now,
we see that we need 670/120 = 5.6 or 6 panels. (We use 120 Watt panels). So we
need the space on the roof for 6 panels. The typical size of one panel is 65x39
inches. We need 106 square feet of space. We put the inverter size at more than
that of the solar panels so throttling gets eliminated.
